I was taking doxycycline for a lesion on my face. I started to have tingling of my feet and fingers but did not associate it with the medication. I only used the doxycycline for two weeks. The tingling in my feet lasted for almost 5 weeks.
Several months later I went on Doxycycline because I thought I had lyme disease. After being on the Doxy for one week I started up with burning sensations of my hands and feet. Puffy, red hands...burning on different parts of my body. My Md said it was anxiety! An immunologist said it was peripheral nueropothy from drinking too much!!! I knew both diagnosis were bogis....then I started to research doxy and came upon this site...thank God. I finished the month of the Doxy. I have been off the med now for two months and the symptoms are finally starting to subside.
I can remember waking up one night and my entire chest felt like it was on fire. Wearing shoes was so painful that I wore slippers to work...I was a burning tingling mess and I am convinced it was the doxycyline.

My 12 year old was on Singulair from age 4 to 10. We too thought it was a life saving drug. The doctor then put my youngest son on it for allergy cough etc. That is when all hell broke loose. He immediately had signs of depression, anxiety, anger, nightmares, ocd and facial ticks. We took both boys of this drug and I will never use it again.
I've told every doctor that we visit about this and they have basically said they haven't heard this as a symptom. When I told his immunologist this was a symptom he said that if I'm telling him it's a symptom then they aren't going to dispute it. His lack of surprise led me to believe that this wasn't the first time he heard this. This is the same doctor that put my 12 year old on this drug as part of a study through U of M. (At the time, the drug wasn't available for 4 year old)
I would strongly caution anyone about the use of this drug and I wish I had done more research. My son has been off it for 2 years and still has
lingering effects.

I am re-posting this from June. I believe that we have many reasons to suspect that Singulair does indeed penetrate the blood brain barrier. I personally believe that under certain unusual conditions that Singulair can cause neurological damage. I tried before to put together a scenario of brain biochemistry that could explain how this can happen. Of course, I am just hypothesizing and all of my ideas will not prove to be totally correct. From the number of postings here regarding neurological symptoms, I believe that there is an answer out there somewhere. Why the FDA is not searching for this answer is a complete mystery to me.
I believe that it is possible that Singulair causes the same biochemical response in the brain that is cited in this study -- thus causing neurological damage.
"Thus, elevated NO production leading to mitochondrial dysfunction, glutamate release, and excitotoxicity may contribute to neuronal death in neurological diseases."
IS SINGULAIR CAUSING THE DEATH OF NERVE CELLS IN SOME PATIENTS? DOES THIS HAPPEN - ALTHOUGH INFREQUENTLY- BECAUSE OF GENETIC OR BIOCHEMICAL FACTORS OR BOTH?

I have stated many times that I am not an expert. I just post what I find. This has been a mind boggling journey for me. This is way over my head but I struggle to read and understand. Finding answers to why children are suffering from neuro-psychiatric side effects is worth the effort.
I have made the following observations.
1. Some quinolines are known to be able to cross the blood brain barrier.
2. Molecules that ionize are known to be more likely to be able to cross cell membranes. So if montelukast ionizes as a result of change in blood pH to sufficient acid conditions, then it could be possible that it does in fact cross the blood brain barrier.
3. We know that there are cysLT1 receptors in the brain.
4. We know that researchers believe that montelukast may bind at the arginine of the cysLT1 receptor.
5. We know that arginine contains four nitrogens. And montelukast contains one.
6. We don't know what happens to those nitrogens. Are those nitrogens converted to nitric oxide?
7. We do know what macrophages create nitric oxide as I posted.
8. We do know that if something cause excessive nitric oxide to build in the brain that there would be damage to the neurons.
Some people may remember when I got stuck at the astrocytes, the cysLT1 receptors and glutamate. I keep looking for research reports that may shed more light on this.

Résumé / Abstract
We determined the ability of pathological levels of nitric oxide (NO) to cause glutamate release from isolated rat brain nerve terminals using a fluorometric assay. It was found that NO (0.7 and 2 μM) produced (4 and 10 nmol/mg of synaptosomal protein) Ca2+-independent glutamate release from synaptosomes (after 1 min of exposure). Spermine/NO complex (spermine NONOate; a slow NO donor) and potassium cyanide (an inhibitor of cytochrome oxidase) also caused Ca2+-independent glutamate release. Preincubation of synaptosomes with 5 μM 1H- oxadiazole quinoxalin-1-one (an inhibitor of soluble guanylyl cyclase) had no effect on NO-induced Ca2+-independent glutamate release. Ca2+-independent glutamate release produced by NO was greater in a low-oxygen medium. NO, spermine NONOate, and potassium cyanide inhibited synaptosomal respiration with a similar order of potency with respect to their ability to cause glutamate release. Because NO has been shown previously to inhibit reversibly cytochrome oxidase in competition with oxygen, our findings in this study suggest that NO (and cyanide) causes glutamate release following inhibition of mitochondrial respiration at the level of cytochrome oxidase. Thus, elevated NO production leading to mitochondrial dysfunction, glutamate release, and excitotoxicty may contribute to neuronal death in neurological diseases.

Oh My Gosh - as I sit here with abdominal cramps typing my experience - I can see the light at the end of the tunnel. I started taking Lisinopril in late April 2008. On May 2 I had severe abdominal cramps and massive vomiting for 8 hours. Finally got myself to ER after I sent my family on to our vacation (I joined 2 days later). The ER attributed it to food poisoning. Lo and behold, I had another "attack" on May 9th. Back to ER I went (my husband witnessed my attack and insisted I go). They took X-rays and MRI - found intestinal inflammation but didn't know why. My internest send me to gastro dr. Third attack hit on June 5th and gastro doctor sent me to major hospital ER. They, too, did MRI & blood work. Looked at gall bladder, pancreas, stomach, intestines, etc. They found intestinal inflammation. Gastro Dr. took more blood and did more test (CT, MRI, Colonoscopy, Endoscopy). He couldn't find anything so he sent me to rheumatologist. She did add'l blood work and genetic testing. She though I had an auto-immune disorder - like Mediterranean Familial Fever! Please...! But all her tests came back negative. She too had no answers, only treatment for symptoms - Colchicine and Prednisone. Yuk. After having my 8th debilitating attack yesterday (since May), I've had enough. I went to the Web and found this wonderful site - along with some others with helpful info. I don't have confirmation that the lisinopril is causing this - but it sure sounds like it. I am a 49 yr old female and I've had no "life changing" events in my life (except for this nastiness) and have been on no other meds. I find it interesting that out of all the doctors I've seen - and all knew of the lisinopril - that none suspected this as a side effect.

Update about my post about the Chinese researchers who reported leukoteine receptors in the brain. There were a few people who misunderstood what I was trying to say to you. I was trying to say that yes it is possible or at least not impossible that Singulair does interfere with brain function in some people because at least one group of researchers found leukoteine receptors in the brain.
I located an article where a professor at Emory was quoted as saying that psychiatric side effects could be possible if leukoteine receptors exist in the brain. That is what I was trying to say without getting myself in trouble for giving misinformation. There is quite a bit more that I would like to say but I cannot find proof as of yet but I am working on it.
Merck’s Singulair likely to see prescription drop-off only in high-risk populations
By Beth Herskovits and Gayatri Iyer in New York

--------------------------------------------------------------------------------------------------------
Merck’s asthma and allergy drug Singulair may see a decline in prescriptions due to recent concerns about suicidality, but the drop will not be precipitous, physicians told Pharmawire.
The warning will likely cause the biggest prescription fall-off among patients with a personal or family history of depression, or patients with mild disease, they add. The drug is taken daily to prevent asthma attacks and allergies, or as needed for exercise-induced asthma.
”Both my kids are on Singulair - and I’m not going to take them off it,” said Dr Lawrence Ciesemier, an allergist and immunologist who practices Kirksville, Missouri. ”It was a surprise to me that this data came out.”
Dr Gregg Santilli, an allergist and immunologist in private practice at AirCare in Plano, Texas, noted that he has prescribed Singulair - a drug he helped launch - for 10 years without seeing any suicides. ”Apparently this is an extremely rare event,” he said. ”This drug has certainly not been linked in a causative way to this.”
”The real question is whether the is greater than what’s seen in the general population,” said Dr Jay Portnoy, president of the American College of Allergy, Asthma and Immunology. ”It’s still an extremely safe and effective medication.”
The FDA announced yesterday that it is ”considering” regulatory action after post-marketing reports seemed to link the asthma and allergy blockbuster to suicidal thoughts and action. Officials said in a statement that they are undertaking a nine-month review of Singulair and three other leukotriene modifying medications: AstraZeneca’s Accolate and Dey’s Zyflo and Zyflo CR.
------------------------------------------------------------------------------------------------------------
HERE IS THE PART ABOUT THE LEUKOTRIENE RECEPTORS IN THE BRAIN
Dr Douglas Bremner, director of Emory’s Clinical Neuroscience Research Unit, noted that drugs can cause psychiatric effects when the targeted receptor also exists in the brain. But he added that it’s unclear whether the brain has leukotriene receptors.
----------------------------------------------------------------------------------------------------------------
He noted that despite the updated label, the side effects ”sort of flew below the radar.” However, he painted a grimmer picture of the effect on the market, saying this would affect Singular sales badly. People are likely to stop taking it, he added.
Over the past year, Merck has updated its safety label to include reports of tremors, depression, suicidality, and anxiousness, the FDA said.
But Dr George Philip, senior director in clinical research for Merck, noted that none of the reports of suicidality came out of clinical studies. He added that post-marketing reports can be ”sketchy” and ”not well-defined” - making it more difficult to determine whether the drug caused the change in behavior.
Asked about whether certain high-risk patients should avoid Singulair, he said, ”It may be part of the dialogue moving forward. These are still unanswered questions.”
He added that other allergy drugs have also been linked to suicide, including Pfizer’s Zyrtec.
Santilli noted that he would consider each patient’s individual risk factors - and the severity of their asthma - before making any treatment changes. GlaxoSmithKline’s Advair has a black box warning linking it to an increased risk of asthma-related death, he said, and Zyflo patients must be monitored for liver toxicity.
”Every drug has risks and benefits,” he said. ”Singulair seemed to be a very clean, very safe drug.”
Ciesemier agreed. ”I prescribe Singulair daily,” he said, but conceded that ”maybe this wouldn’t be the first choice” for patients with a history of suicidality.
Patients who are taking the drug for allergies, a less serious condition, might be more likely to switch to an antihistamine, Santilli noted.
Singulair earned USD 4.3bn last year, growing 19%, and is the bestselling respiratory product on the US market, according to the company. Merck has a market cap of USD 96.57bn.

I have a 10 year old daughter who took Singulair from age 3 until this past November. She has severe asthma/allergies. When she was 6 the night terrors started I informed the pediatrician of this, but they said she probably had sleep apnea. Her concentration level kept her in trouble in school. I never considered that it might be the Singulair. She developed a speech problem and the school speech teacher referred us to a speech pathologist because they thought she might have vocal fold dysfunction. Several specialists later, we wound up at an allergist's office who IMMEDIATELY took her off of Singulair stating that it was a dangerous drug and should have never been prescribed to her.
Her health has IMPROVED off of the singulair and we are doing allergy shots and symbacort with allegra. I wish I could have saved her the emotional roller coaster ride - all because of this drug.

I was given 20 mg of Prednisone for 10 days for a rash and joint pain.
The pain went away and I felt great the rash got a little better. Two days ago I took my last pill. I woke up that night and my knees gave out. By morning I was great! Next night I woke with knee problem again had to slide down the stairs to the living room. I got to wondering if the knee thing could be associated with the Prednisone. I got on line and read all this terrible stuff. I am so Horrified! Today I am in pain like my body is bruised and my face is swollen a little. I have acid reflux as well. Non of this is typical for me. My knee thing is ok again, but I am just appalled! I have no MED insurance. I hope this isn't the beginning of worse things I am not taking that drug now. The Dr. didn't say I needed to taper...
I hope I have not damaged myself by taking this drug! My heart goes out to all of you! My question is - Why are the Dr.'s prescribing this terrible drug?

My son is 4 1/2 years old and has been on Singulair since he was 2. We have been happy with the improvement we have seen in regards to his asthma. No more breathing treatments have been great. The last couple of years though he has continued to get severe headaches that put him out for at least a day with high fevers. The first time it happened was when he was 2 and he had a mild seizure with spiked fever. I haven't thought about it at all until he was due to get another headache and hasn't. We have missed some doings due to the holidays and walked out schedule. The timing and symptoms are seeming a little to coincidental. We have seen a hematologist and immunologist for his chronic headaches but no one knows why he is having them. He has even been admitted for them. His white blood cell count has been elevated with no known cause as to what his body is fighting. I think we will take him off of the Singulair for at another month and see if he gets anymore headaches.

I'm loving it.
After trying every HRT and pill under the sun for surgical menopause, and I'm in my 30's, I'm glad I've finally found something that makes me feel better.
Trust me here. Everyone is different and it may take you a thousand different medications until you find the right one, especially with hormones, but when you find the one that works for you life as you know it changes for the better.
Don't listen to that bollocks about HRT or the Pill causing you breast cancer and death... not having HRT or the pill etc can cause you just as many difficulties. Some of you may get osteopenia, vaginal atrophy, and other things that are very private. Let's face it, death can come after you even if you're not on hormones, just look at a children's hospital if you want proof.
I wish all of you suffering from hormonal conditions a healthy long happy life. I know the journey there is hard, but never give up. Just try something else. Even giving hormone therapy a break for a few months and then trying a different drug or approach such as a smaller dose.
Perhaps it's not even your hormones causing the problem, perhaps you should seek a specialist physician, immunologist, endocrinologist or just find another doctor that understands what they are doing and actually helps you.
All of the above saved my life. All of it. Together. It is a long hard road ladies but it's your life.
Blessings to you all.
