Allergic reactions symptoms and conditions

My mother is on Bactrim for a UTI. She has Alzheimer's disease, but can normally function pretty well. Two days after starting the three day treatment she got more confused and couldn't even figure out how to take her medication. Now she has leg pain, muscle weakness, and joint pain although I think it has helped the UTI.

I'm not a person that necessarily thinks the drug should be removed from the market because of what I've read here. We aren't reading posts from the thousands of people that it has helped without ill effects. All drugs potentially have side effects. There is always the potential for adverse reactions or allergic reactions. As a matter of fact, many people on this forum continued to take the medication when they were clearly having allergic reactions making themselves sicker in the process. We must be diligent and educate ourselves about medications and not just rely on someone else to tell us that it is fine. That being said, I feel for those on this board who have endured such suffering and hope that they recovered without incident.

I was prescribed this drug for a UTI. I've been on it for 6 days already (10 day treatment) and thankfully have not experienced the severe side effects that some people on this site have. I noticed that a few of the entries mentioned that people with penicillin allergies shouldn't be put on this. I'm surprised that my doctor put me on it in that case, but I haven't really had any allergic reactions to it.

However, I have had a few minor side effects. A couple days ago, I had a horrible headache. As for anxiety/depression, I was suffering from that anyway due to real life circumstances so it's impossible for me to tell whether or not the pill had any effect on it (I don't think so, because I feel fine now). As for ongoing side effects, I have actually felt extremely gassy lately, and I know it has nothing to do with my diet. The first day on this pill was fine, but after that I started experiencing this problem. I also had some diarrhea when I first started on it.

Well, I'm done with this pill in four more days. The good news is that it COMPLETELY cured my UTI and I definitely feel much better than I did when I was running to the bathroom every five minutes.

Saw Levaquin on the news yesterday. I was very pleased to see that they are putting a warning on this med. I thought it was just me with a problem with Levaquin. I have allergies to antibiotics anyways so I attributed my problems to just another allergic reaction to an antibiotic. Wow!
I took Levaquin in April 3 years ago for a respiratory infection of some kind. I then had the same experience I have with allergies where my tongue felt swollen. I called the nurse and she told me to take the next dose anyway. I did so and my chest/esophagus felt like it was on fire. I couldn't breathe. I went into the Emergency room and they gave me a lidocaine/maalox combo that would take the pain away for a while and diagnosed me with reflux.
I went on some reflux medications later that caused more problems for digestion. The more we tried to solve it the more my system reacted. I ended up in the emergency room about 5 times that year. Two were for chest pain from the esophagus and two were from severe allergic reactions (anaphylaxis). I became allergic to many categories of food and lost down to 110 lbs. I went to naturopaths and other specialists and none of them could pinpoint any problems. I was tested for Celiac and had two upper GI and one lower GI that year alone, My Dr. bills totalled more than $5,000 for that year.
The next year I had given up. The only doctor that I would go to was the allergist and the new GI doctor I had found. I still worked but was in such severe pain that I did nothing but sleep when I got home. I cried and begged God for death or healing all night long. I was losing my hair in great handfuls. They put me on ativan and I became addicted to the stuff. I was allergic to most foods. I had a diet of about 6-10 foods that I would cook homemade and I would never eat out unless I knew what and how the food was prepared. I took vitamin c in very high doses and that took the pain away.
I slowly re-introduced food back to my system. Now I have a less restrictive diet but it still is limited. I am now allergic to all nuts, rice, sunflower seeds (sunflower oil is used in most potato chips), some other grains, and melons. I still have problems with legumes and some other foods.
It took 2 years for the pain to subside and I still have digestive problems with diarrhea on and off. I am fine just as long as the pain stays away. I don't mind being limited on my diet.
I had noticed that my legs and joints hurt during that time too- but the other pain was so severe and my diet was so limited that I attributed that to diet.
If there is a class action lawsuit on this stuff I would like to be involved.

I am a 56 y/o female who started on Fosamax last Sunday. I have a dx of osteopenia. I followed the directions of taking pill with full glass of water and remained upright for 30 minutes before having anything to eat. I was fine on Sunday but on Monday I woke with SEVERE bone pain! My whole rib cage, back, knees and heels were hurting so bad. It felt like I had pain in every bone in my body. I could not take in a full deap breath as my rib cage was hurting so bad. I could not bend or turn without terrible pain. My energy level was zero. I immediately called my doctor who told me to hold the Fosamax (ya think?) and ordered Vit D lab levels. Apparently when you Vit D levels are off (don't know if too high or too low) you can suffer this bone pain. I am awaiting the results. The pain is better today and I was told it takes 5 days to get out of your system. I only wish I had done my homework and found this site before taking this poison. I have to say I'm a registered nurse and know that ALL medications have side effects and everyone responds to meds differently. Some side effects subside as your body gets use to it and some can experience severe allergic reactions. But it's important to weigh the risk vs the benefit. I would rather deal with osteopenia in another way. So my search begins for alternatives to Fosamax for good bone health. Has anyone had good results with other supplements/meds?

The backs of my hands burn and have red blotches...they burn if the sun even touches them (tough to do anything outdoors...michael jackson gloves, or what?)...they also burn when I run water over them. I'm taking 200mg twice daily for chronic lyme...and am toward the end of the second week of a three week protocol. After reading some of these comments and other allergic reactions elsewhere, I've taken my last dose about an hour ago...

(I love the sun, and am afraid I'm turning into some of those people you see with huge wrap around sunglasses and arab clothing...I want the beach, surf and sail...)

I was prescribed Avelox for an infected insect bite. I took my first daily dose Saturday evening. I woke up Tuesday morning with large painful welts covering my neck. They were very itchy and hurt very badly. Today is Wednesday and they are continuing to get worse and spread. I just made the connection today that this rash is likely due to Avelox. Im a healthy 27 year old and Ive never had any allergic reactions to medicine before. The infection in my arm went away quickly, but the rash on my neck is terrible.

I started using Zyrtec recently after my niece received it from her doctor as the solution to her allergies. (We bought it at the drug store). My allergies are skin related where i walk and feel a deep itch in my thighs and anywhere else i have tight clothing. Also when i work out - i have itch deep skin. This is under the surface and very uncomfortable especially when you are walking/working out. Leads to confusion etc. I had never used any allergy medicine before but decided just to see if i would feel any different.

Anyhow, I started using Zyrtec the other day and almost immediately, I started fighting with my boyfriend - everything i was angry with him about came out. It was helpful but also i was very mean in my approach. I also started getting back pains around the spine area - not in the spine but around it and could not sleep until i took an ibuprofen. Today i experienced left shoulder and back pain. That was it for me and whats funny is that i took the lowest possible doze. So i am not touching that medicine again. I am a 36 year old woman. Its a strong medicine and something is strange with it (changes moods etc). I will have to change the medication for my niece before she goes through the side effects.

My son age 3 was diagnosed with asthma about a year ago. Since then he has been sick constantly. Most recently his doctor has prescribed Singulair. He is aggressively pushing it on us. I stated my concerns to him, and he said there is nothing wrong with the drug.. he gets all the news letters.. and all the things I listed was the first time he heard anything.. I asked for his to refer us to a specialist and he wont.. I cant find anyone for a second opinion..My son needs medicine- at night i cant leave his side cause of his breathing.. The doctor wont suggest any alternate and I am stuck. I keep reading about all the people who are not taking singulair anymore- what what are they taking? I am completely lost here!

My doctor has put me on Levaquin 500 mg 5-7 days every time i get a sinus infection, bronchitis or laryngitis. I haven't had any side effects or allergic reactions to the drug so far. I'm allergic to amoxicillan though. Sorry to hear about everyone having allergic reactions to the drug.

Flindy is correct. It is easily possible to be just plain allergic to montelukast- Singulair. Where were the other "allergens" that her child was exposed to? It was, at least hopefully, a sterile environment.

Montelukast is a quinoline. Drugs often are built around a core molecular called a pharmacophore, the molecule responsible for the drug's important characteristics. There is an enormous amount of literature regarding adverse side effects for other drugs in that category.

At the time when Merck was pursuing quinoline as the pharmacophore, other companies were pursing other core molecules. So a quinoline core is not the only choice of drugs. The huge problem is that doctors are not aware that Singulair is not an anti-histamine. They are not warned that the core molecule is a quinoline so they don't know to watch out for allergic reactions especially serious ones.

It would be common knowledge that a quinoline radical (in an acid pH) could react with hydrogen peroxide to produce quinilinic acid, a nasty neurotoxin. When I hear of neuro-psychiatric side effects that appear to coincide with times when hypoglycemia could be happening, then maybe there are some genetically pre-disposed people that actually are experiencing times of ketoacidosis. Scientist have known about quinolinic acid since the 1940's. Malaria drugs containing quinoline come with a warning about hypoglycemia and electrolyte imbalance. Which comes first - the chicken or the egg- the reaction to the drug then the hypoglycemia or the hypoglycemia then the reaction? It would be amazingly easy to prove whether quinolinic acid is responsible for these neurological side effects.

I am appalled by two things. One is that Merck has such power over the FDA that the FDA fails to even recognize basic pharmacophore characteristics. Merck manages to snow them somehow with just words - leukotriene receptor antagonist. So what is the FDA reaction? Merck should review their clinical data. How about find some people who are suffering from Singulair side effects and do some tests? Then you might actually find out why.

If it turns out that anyone at Merck or FDA knew that montelukast carried significant risk of allergic reactions due to it's pharmacophore and they chose not to reveal that in the literature for marketing reasons, those people should be prosecuted. It should not be the job of doctors who prescribe medications to do their own research.

I spent the weekend reading about the development of Singulair. The early studies recognized that the first phase of the acute asthma response bronco-constriction was probably not caused by leukotrienes. They identified histamines and prostaglandins as the probable sources. I don't think that changed because the Singulair literature states that it should not be considered as a treatment for that. Leukotrienes were a source of inflammation caused by eosinophils and mast cells present in greater numbers (than normal) in airway tissue. So, it was beneficial to find a way to decrease that.

The cysLT1 receptor was identified as source of the signals that tell the cells to produce leukotriene. The receptor, a gene, consist of 337 (they think) amino acids. They modified a compound that would bind to that receptor thus blocking the cells ability to produce leukotrienes. This compound is very specific. It was formulated to bind to the "model" receptor. This compound will not even bind to cysLT receptor sub-types. (That is the good thing.) There is an enormous amount of research that discusses the genetic variability of the chemical reactions that occur in the leukotriene (calling it this for simplicity) pathway. We are also seeing that a number of researchers would like to use gene profiles to predict whether patients will respond favorably to different asthma/allergy drugs. ALL PATIENTS HAVE A RIGHT TO KNOW IF IT IS INHERENT THAT SOME PEOPLE WILL NOT RESPOND TO SINGULAIR OR RESPOND ADVERSELY.

There are many studies from the 1998 era that conclude that montelukast is not effective for everyone. Those researchers stated that it can be predicted that those people who are going to respond favorably will do that within the first 14 days or so. That conclusion would be consistent with a genetic component for efficacy and safety of Singulair. Those doctors concluded that those who did not respond within that time frame should not take Singulair for fear of harming them. That makes good sense.

The Italian researchers wanted to know if there was more going on than blocking leukotrienes in the action of montelukast. They set up a "test tube" study regarding montelukast, the cysLT1 receptor, and some t-cells that they selected. Why? Researchers always have something on their minds. They observed the death of these particular t-cells.

Montelukast is a quinoline. We basically know of quinilines and quinolones as compounds that were invented as broad spectrum antibiotics. They work because they interference with bacterial DNA so they cannot replicate themselves. Montelukast is a quinoline modified to bind with the cysLT1 receptor (a gene) and prevent that gene from activating. That's consistent with what a quinoline/quinolone does.

So what does montelukast do in blood plasma if it does not bind to the receptor because of genetic mis-match? (If montelukast does bind, then a chemical reaction has occurred and the liver will break down the by-products. Montelukast metabolized in 10-12 hours.) What happens if it doesn't bind? How long before it breaks down? Does it produce toxic by-products?

I want to know what happens to lymphocytes such as t-cells just because montelukast is a quinoline. Maybe nothing but what's up with the Italians researchers? I want to know if montelukast has the capability to interfere with lymphocytes who can clone themselves. That could be a good thing under circumstances when these lymphocytes are causing inflammation. But it could be a bad thing in the case of normal individuals with no problems.

I want to know if the bad side effects are due to the fact that the body has to break down and metabolize a quinoline that did not bind to the receptor for which it was created. The side effects of Singulair are strangely similar to what is observed in the quinolones such as levaquin. I have not as yet been able to compare montelukast as a quinoline to levaquin as a quinolone. I am hoping to find something on these categories. There may be no reason to worry that they cause similar damage. But frankly, I think that there is. There is some terrible chit happening to some people. The scariest is the neurological damage.

All of these questions would be in the everybody pharma knows to ask category. I don't know where the answers are. I haven't found them as of yet. Maybe there are no answers. We have to remember that Singulair and Vioxx were released in the same year. They have continued to be drugs under the current executive management of Merck. If the Vioxx marketing promoters had their ghost writers, why not the Singulair marketing promoters. The genetic component appears to be widely accepted but we haven't heard one thing about even that.

I think that it is sad that maybe the marketing of Singulair as one stop shopping for asthma/allergies may have destroyed the original concept. I really think from reading the original work that they knew that they couldn't engineer a drug for one size fits all. Everybody gets harmed when information is withheld.

Shame on the allergist who yelled at the mother who wanted to discuss issues. Does he know exactly who is allergic to Singulair and who isn't? Get him a dunce hat. Just because Singulair is marketed for allergies does not mean that you cannot be allergic to it. See the power of Madison Avenue? The ad agencies focus group these drugs to death. The ad agencies cleverly craft the product information. A good piece of legislation would be to prohibit consumer drugs ads.

I don't know if my 1 1 /2 year old son's being diagnosed with low igG and low IgA have anything to do with singular. He just got off it 2 weeks ago, had been on it a year. He was tested for allergies everything was negative, but tested very high positive to gliadin IgG (95.5), and positive to gliadin IgA (14.8). Is this related???? HELP!!!!!! The GI Dr want to do an endoscopy on Friday May 2. Any help, I don't want my son under anesthesia unnecessarily..................

I have taken Prednisone several times for allergic reactions.The main side effects I have encountered are 1.Shakiness 2. mood swings 3. anxiety-mild depression 4.upset stomach 5 rapid heartbeat.6.insominia. To counteract the anxiety, moodines, insomnia I take benadryl. I talked to my pharmacist and she said Benadryl is ok to take with Prednisone- you should still talk to your Doctor or Pharmacist. The Benadryl takes some of the edge off of the prednisone. As for the upset stomach I just make sure I eat before I take the Prednisone.

I have been on Lisinopril for about 2 and 1/2 months for borderline hbp. About 135/85. I have two cats which have always have caused some allergic reactions but I had that controlled with an air purifier. I really haven't had any bothersome symptoms until about 3 weeks ago when I noticed that I was wheezing during the day (while away from the house, so I couldn't blame the cat allergies) and I was getting very short of breath doing everyday tasks and just talking to people. Then I started noticing a strong post nasal drip and a lot of congestion during the night. To the point where I sounded like something from the Excorcist, my breathing at night was rattly and wheezing. It suddenly occured to me that all of this could be developing side effects from the Lisinopril. But I didn't want to give up so I started taking Claritin at night and in the morning to relieve some of the exasperated allergy symptoms. That worked for about a week, but then I would wake up coughing and finally last night the wheezing got so bad that I thought I would need to go the ER. Today the coughing started pretty badly and just taking my dogs for a walk was taxing and I started getting really tired and developing a headache (which never happens to me). After researching Lisinopril and now reading everyone's posts and symptoms and obviously experiencing this terrible cough and wheezing, I have made up my mind to go off this terrible drug. I can't live with this. I am only 42 yrs old and I feel like I am an 90 year old with emphysema. Bye bye Lisinopril.

I have been taking this medicine for a UTI for a few days and today all of the sudden I had an uncontrollable need to pee every few minutes. When I did there was a burning sensation and the immediate need to pee again. So I looked up the medication and saw online that you are supposed to drink a whole glass of water with each pill. I started chugging water and the burning and need to pee went away after and hour or so. Very strange, but maybe it will help someone else.

I also just heard about the Singulair side effects. I am a 58-year-old female with recurrent sinus infection and general allergic reactions. I had testing at my ENT's last spring--I was allergic to nothing specific. It was thought that I am generally sensitive to lots of different things. Well, the ENT put me on Singulair and I never put two and two together until now--- I became extremely anxious and depressed, couldn't sleep, my legs were so restless at night that it was unreal. I also had frequent urination and bladder spasms, low pelvic pain, etc. Over the winter, I stopped taking the Singulair and gradually was able to get off Lunesta and an anti-depressant. These were the worst months of my life---I went through all kinds of urinary and gyne testing to no avail. The urologist couldn't give me any answer---just that he though it might be a neurological issue so I also spent a lot of time and $ getting CT scans and MRI's to no avail. I really thought I was losing my mind---it was half a year during which I was definitely not my usual healthy, upbeat self. I will never touch Singular again!

I have been on Avelox for three days and pretty much I'd say so far, so good. I have had some anxiety, which I am prone to, but I would probably guess that some of that came from reading all of these posts. I am allergic to most antibiotics, so I do understand allergic reactions. I have been suffering from advanced tonsillitis for about two months. Nothing else has helped. After three Avelox I feel like a new woman. Again, I would not say it is side effect free -- I have had some insomnia and anxiety. The first pill I took during the day and felt very bizarre. The next two I took at night along with a Xanax to help the anxiety and sleeping. So far it seems to have fixed the problems I was experiencing. As I said, I am definitely not out to discount anyone else's experiences, because they sound horrendous. I just wanted to give some hope to those others out there who are allergic to just about everything else. I'm doing well so far, and it really seems to have cleared up my infection when nothing else was working. Here's hoping the next seven days go just as smoothly!

Let me just start off by saying that I have not had any allergic reactions to medications before. I don't have allergies to any foods or external stimuli like dust or pollen. But literally two minutes after taking Avelox, I started sneezing uncontrollably. Then my nose filled with mucus and I started itching all over my body, most notably on my arms, legs, and scalp. Then I felt that my skin was burning. I looked in the mirror and my face and body were bright pink. I called the pharmacist and she told me to take Benadryl and if my throat started to close up I should go to the hospital. Well, I didn't have any Benadryl, because I don't have any allergies, so I had to drive three blocks to the CVS. At this point, my face is starting to swell up: my eyelids, my nose, my lips and my ears are twice their normal size. I have hives all over my arms and legs. I'm shaking because I feel so cold--my body temperature was only 94 degrees. I took two Benadryl but it didn't really work until I took the 2nd dose four hours later. I ended up at the hospital because I felt like there was something stuck in my throat and was unsure whether that meant that my throat was closing up, but they were so busy that I never made it past triage, where my blood pressure was only 80/40 and my heart rate was 120. We waited in the waiting room until I was able to take the second dose of Benadryl and left. All this after only one dose. I would advise extreme caution with Avelox.

Obviously, none of you have read the pamphlet that comes with your b.c possible side effect #1 Irregular Vaginal Bleeding

possible side effect #5 Other side effects " other side effect may include nausea and vomiting, change in appetite, breast tenderness, headache, nervousness, depression, dizziness, loss of scalp hair, rash, vaginal infections and allergic reactions.

and these are side effects on ALL b.c pills, not just Femcon fe

I had my Mirena IUD inserted in January of 2003, The doctor had some issues placing it and got it to stay on the second painful attempt. I spotted that day and the next but no more. I haven't had a real period in years. Occasionally over the past year or two I would have spotting lasting no longer than an hour or two. No real cramping to speak of but I have added about 15 pounds over the past 3 years and I had not changed my diet or exercise and am not even 30 yet. I have gotten emotional beyond my control a few times unexpectedly leading me to wonder what is wrong with me. I have had extreme dandruff in just one small area for the past 2 years and overblown allergic reactions to my normal allergy triggers for the past 2 - 3 years as well. I put off getting the IUD out because it has been easy to dismiss all these as superficial, unrelated, etc....I went to have it out and they can't find the string now. At this point I have to go for an ultrasound so they can find out if it is up in my uterus or if it perforated and is beyond my uterus somewhere.

Here’s a little update from my last post, I hope it may be useful. The reference to snake venom set me thinking, as around six years ago I suffered anaphylaxis after being stung by a wasp on the end of my tongue. I was rushed to casualty as my head and ears swelled up. I was coved in a red spotty rash and although the major symptoms subsided after a day or so after treatment , it after several weeks before I was back to normal. I now carry adrenaline in case of a similar incident. Many of the symptoms were similar to what I have experienced over the last month, the shortness of breath, the red spotty rash ( forgot to put that in the last post. I still have the spots on my arm and back!) , painful joints, blurred vision etc….

So it got me thinking, is there a connection? It would be interesting to note if any of those posting here have similar intolerance to insect venom.

A quick Google brought up a reference to a paper by Janice L Stumpf, Nadine Shehab and Anish Patel in the Annals of Pharmacotherapy Vol 40 No 4 p699-703 titled ‘Safety of Angiotensin-Converting Enzyme Inhibitors in Patients with Insect Venom Allergies’

In the conclusions it states ‘….it seems prudent that patients with document allergic reactions to insect venom avoid ACE inhibitor therapy, if possible..’

I’m convinced that I was slowly going into a form of anaphylaxis brought on due to allergic reaction to linisopril, I now know what I will be telling my GP, as I’m sure many doctors will be unaware of this link. Make sure that if you suffer from the same intolerance that your doctor is made aware.

Hope this helps.

I was recently prescribed this medication for a UTI. I have taken this medicine a few times before. Honestly, I have NOT experienced any side effects from it. It always successfully clears up whatever issue I have that it was prescribed for without incident. If you experience any of the side effects everyone else here seems to be having, I would suggest talking to your doctor and switching to a different medication. Allergic reactions are quite common to this medicine. When you take it, you should hardly notice anything at all besides that your symptoms are improving. Any other reaction should be dealt with immediately. Don't go cold turkey though! Just talk to your doctor and find another option.

Very bad rash that a week later has not gone away. Nexium actually burned my skin! I look like I have color like I just came from the beach. This is a dangerous drug. it works for the reflux, but the side effects arent worth it. I also develiped hip pain, like it was sucking the calcium out of the bone! The hip pain is gone, but i still have burning, itchy skin, and red all over, less than a week later after stopping, about 5 days off it now. Be careful if you are sensitive to hives, this medicine brought me to the emergency room with swollen hands and feet. it is dangerous!

I had been on lisinopril for 3 yrs until a couple of weeks ago. I was taking 10mg in addition to 25mg atenolol(which I have been on for 10yrs). Although I did not notice any serious side effects when I first started on it, it ended up seriously affecting my quality of life. My energy level, which has always been very high, was gradually reduced over the course of the last 3 yrs to a level so low that it was exhausting just to get through the day. I had undergone extensive lab workups to try to figure out what was wrong. I would also have episodes of severe muscle weakness and aches that kept me confined to bed. I was tested for every disease known to man. All came back negative. On top of this, for the first time in my life, I was becoming very depressed and unable to cope with the least little thing to the point where my family became concerned. I also suffered several serious anaphylactic allergic reactions involving serious stomach pains, plummeting blood pressure, pounding heart rate, faintness, swelling of my extremities and shock. I was referred to a specialist and after 4 wks of bloodwork and skin testing, I was incredibly allergic to NOTHING. But I have to carry an epi pen at all times since I don't know when or why a reaction will reoccur. All of this time, I never ever suspected lisinopril as a problem. It was not until one day I was particularly tired and lightheaded and found out that my BP and pulse were way too low (90/50), so I did not take my lisinopril that night (or since then) but only my atenolol. The next day I felt better and within a couple of days incredibly better. My doc has agreed that lisinopril is a problem for me and increased my dose of atenolol to 50mg, which takes care of my BP just fine. Now my energy is returning, my depression has lifted, and I can actually look forward to each day instead of just trying to get through it. I feel like my spark for life is coming back. Like others, I was in a downward spiral and wondered if this is what happens when you turn 50 and if I would ever feel good again. I knew nothing of this website during all of this and wish I had found it long ago. Maybe, just maybe, I would not feel like I missed the last 3yrs of my life.

I began taking sulfameth about 1 week ago. Everything seemed ok until one morning I woke up and my neck was completely stiff! I started getting the hot and cold feeling and a splitting headache with nausea. I took tylenol and it seemed to improve a little. That evening I woke up every ten mins, just unable to get quality sleep. Next morning I woke up (after no sleep again), COVERED in hives. I mean, from my head to my ankles, these huge, red, itchy things all over! My throat, too. You know how it feels right when you swallow?..that's how my throat felt constantly. I was completely freaked out as hubby was at work and I was home alone with my 4 kids. So we hauled booty to the clinic and sure enough, allergic reaction to the antibiotic. I'm actually allergic to penicillin as well, so the doctor I saw said she was really surprised my other doctor would have prescribed a sulfer drug to me as it has a high instance of causing allergic reactions. hhhmmm...thanks.
Anyway she said I could take benadaryl, but better yet, Claritin. She said Claritin won't make you drowsy and will knock it right out (you should take benadryl instead of claritin if you're breastfeeding though). That was yesterday, and besides some weird mottled look on my legs (leftover rash), all seems well.
