Synthroid and levothyroxine

I've been feeling dizzy for about a year and half. Recently switched from levothyroxine to Synthroid and upped the dosage slightly. Now I'm feeling worse! My endo seems to think there is nothing he can do for me but get my thyroid under control. Is anyone else experiencing dizziness from the meds? Is there a med that is better for this?

I don't believe you are experiencing side effects due to Synthroid - I have similar symptoms and just a couple of days ago my doctor and I have discovered that my symptoms may have to do with my PARAthyroid gland. I also have Chronic Kidney disease which also has a correlation to both the Thyroid and Parathyroid.

Ask your doctor to check your Ionized Calcium, PTH (parathyroid hormone), and your Vitamin D-25 - also your cholesterol levels. Also - check out GOITROGENS - certain foods and drugs, including SOY and Milk may affect your body's absorption of your levothyroxine dose (you may not be getting enough)

I was diagnosed with graves disease last year, I had a really acute case that turned me into a total nut job.
In October after going through several thyroid storms and the doctors not being able to keep me stable with medications, I had a full thyroidectomy in October.
I started on .100 mcg of levothyroxine and then the dosage was gradually decreased, I started having a lot of random body aches, mood swings, lots of muscular pains and no energy.
They ended up raising my dosage and detected that I had a large vitamin D deficiency, after several treatments of taking 50,000 units of vitamin D, and also adding my levothyroxine dosage I started feeling better. I still have mood swings here and there, and feel sad periodically, but the last month or so I've been feeling more fine than I have in a long time. They have me on .170 mcg of levothyroxine for two months now. Last week I started getting headaches more frequently, and one of the times I got this nose bleed.
This past weekend I got a headache, and then later that night I had another nose bleed.
I don't usually get nose bleeds or this many headaches so I'm a little concerned.
Also the last time I was getting headaches and constant nosebleeds was when I was really hyperthyroid.
As far as the doctors go, I'm in between insurances and quite honestly I've been frustrated with both my pcp and endocrinologist...

I suggest to anyone that has Hashimoto's Thyroiditis (type of Hypothyroidism) to have a blood test done for Celiac Disease. There has been research done linking Celiac Disease and Hashimoto's Thyroiditis. Celiac Disease can be controlled by a gluten-free diet (wheat, rye, and barley free). In the US, not many doctors recognize/know of this link. I have been hypothyroid for 20 years (had Hodgkin's Disease (cancer) - radiation/chemo at age 16) I have 2 sisters with Hashimoto's Thyroiditis and were iron and B12 deficient. I was diagnosed with Hashimoto's Thyroiditis 3 months ago with iron and B12 deficiency. I have been on a gluten-free diet for 2 months now. My dosage of synthroid (levothyroxine) was 175 mcg and now is down to 137 mcg. I hope that I am one of the lucky ones that will have their antibodies to their thyroid normalized (no more synthroid!) I have a couple of days left before my next blood test and I hope that it goes down more. I am feeling better now than I have in a very long time. I have attached a link for those of you interested. It is an endocrine article from Finland outling the link between Celiac Disease and Hashimoto's Thyroiditis (among other things). I hope that this helps some of you. http://edrv.endojournals.org/cgi/content/full/23/4/464

I'd like to say that I think the Old version of Synthroid that existed
before 1982-83 was MUCH better than what is produced today,
I'd done quite well on Old Synthroid from 1975 to 1982 after
RAI treatment for a bad case of Grave's disease when I was
eleven years old....but when Synthroid was changed to be
more "cost-effective" for its manufacturer, my life was basically
destroyed--and I haven't recovered since then, despite trying many
different doses of various thyroid drugs.

Symptoms I've gotten since Synthroid changed in '82 include:
Severe breathing trouble that really limits what I can do every
single day; extremely dry skin in certain places--like legs and
feet; much poorer memory and thinking ability; much drier hair
and too much hair falling out; tendency to get chest pains whether
dose is too low, too high, or "normal," have had a lot of trouble with
blood pressure at times; getting red in face; too much weight gain
for what I eat; lymphedema (much swelling in legs and feet),
inability to sleep well; always feel congested or blocked up;
vision problems like black spots floating before eyes; sensitivity
to light; double or triple vision at times; involuntary eye-twitching
at times. I'm sure I've forgotten some things, too....

A very odd thing about Synthroid since 1982 (and the other drugs
that've copied it, since that time) is that it tends to give me
symptoms of both high and low thyroid trouble at the same
time, while also causing new symptoms that I'd never had in
the first place. Old Synthroid was much more clear-cut for me.
If the dose was too low, I'd have typical low thyroid symptoms
only (too tired, dry skin, etc), and if too high, I'd get only typical
high thyroid symptoms (too nervous, insomnia, racing heart, etc),
Much easier to adjust and work with than today's Synthroid.

At any rate, I was left with little working thyroid gland after my
intitial Grave's treatment, so I am (unfortunately) very dependent
on GOOD thyroid medicine to help me. In my opinion, I haven't
had any good stuff to take since Old Synthroid left the market
in 1982-83. Haven't been well to accomplish much since that
time--feel like I'm getting punished for being a thyroid patient,
which is ridiculous, really--because I know better medicine once
existed, and I want it again!

Have tried many avenues to get someone to produce Old Synthroid
again, but no luck--I'm not rich, famous, or politically connected,
so no one listens to me. But if anyone out there reading this can
help in some way, please feel free to contact me--maybe we can
work together to bring back a better treatment that would help at
least some folks out there who are really suffering. S.D.

I a 49 year old male. A little while ago I was diagnosed with Hypothyroidism. My TSH was at 43. I have been taken Synthroid for a little over 3 months. I started with 25mcg and was recently increased to 50mcg since my TSH was still at a high 15. I also thought it prudent, since I had gained a lot of weight over the last year and a half, to also diet and exercise a little. In the last 5 weeks I have lost 32 pounds. (I was about 80 pounds more than I liked). I have more energy, have not lost anymore hair than normal, and my hair is not brittle. I have episodes of Atrial Fibrillation since I was 30 and occasional "heart flips" ever since. Since taking the Synthroid I have not experienced these "flips" at all. I sleep well. My blood pressure was High in the past and was taking two meds for it. Since taking the Synthroid (I'm also guessing the weight loss, diet and exercise has also helped) I am down to one med and I now have a BP of 110/65 with a resting heart rate of 64. By the way..I am taking the generic form of Synthroid.

I have no bad side effects on Synthroid, unless I am overmedicated. I get burning feelings on my shoulders, back, arms, and nape. I can't sleep, or wake for no reason during the night. I get very nervous, and have a jittery feeling all through my body. Has this ever happened to anyone?

I was diagnosed with hypothyroidism in April of this year (2007) kind of by accident through a routine checkup. I had gained a bit of weight over the past two years, but that was really my only symptom. I was begun on 75 mcg of a generic brand of Synthroid, levothyroxine. Since I began this medication, I have rapidly gained another 15 pounds despite a 1,000 calorie per day diet. I retain fluid horribly. My ankles, wrists, hands and face swell daily. My muscles ache, especially my legs, upon walking across a room. I'm fatigued, short of breath. My LDL cholesterol level has skyrocketed in only three months and now I'm being told I need to be on a statin drug. I cry frequently and feel uncharacteristically anxious and irritable, but this could be due to the frustration I am experiencing with the loss of my sense of well-being. In essence, I felt much better before being placed on the medication. I may, in fact, discontinue the medication totally and see if over time I begin to feel better. Like so many other stories I'm hearing, my doctor seems totally unconcerned.

I think what a lot of people are posting here are more side effects of thyroid conditions rather than side effects of thyroid medication. After my RAI treatment I started on a generic brand of levothyroxine. I even got my doctor to let me try Armour Thyroid since many people do well with it rather than Synthroid. Armour didn't work well for me, but it definitely is the only way to go for some people. After months of misery, things finally smoothed out. I was a royal pain in the butt to my doctor because I questioned everything. The biggest side effect for me going from hyper to hypo was edema. A clinical name for water retention. It wasn't so much the bloated feeling that bugged me. It was the pain in my hands and feet from the water retention. I have never, ever had a problem with carpal tunnel syptoms even though I have always used my hands a lot for work and I play the guitar. I had to add a small dose of dieuretic to control the edema and relieve the hand and feet pain. Sometimes it does flair up depending upon what I eat and how much I sweat, but that's what goes along with this type of illness. It's not just a magic pill that makes you feel "back to normal". You have to be demanding of your doctor to try other things to get you to feel right. You even have to pay attention to how you feel at different times of the year to figure out how to adjust what you take, eat, or do to feel better. I have noticed that with all things remaining constant, how I feel in terms of energy level and edema is related to the season. The body is weird that way. I still have side effects from the treatment from time to time, but I finally figured out what seems to work best for me. Maybe things could change over time, but I've learned that medicine just doesn't have a black and white treatment plan that works the same for everyone for thyroid related conditions. To sum it up, question everything your doctor tells you, demand to try things that you think would help you feel right, pay attention to what your body is telling you and adjust, and fire your doctor if they treat thyroid problems as black and white. Your doctor is not the one suffering from the condition, you are. It's your life and there's nothing wrong with being demanding about wanting to feel right.

Hi everyone
I've been on Levothyroxine since August 2006. Eversince being on them I actually feel worse. I've always weighed 7 and 1/2 stones and I've actually put on half a stone since last August. I watch what I eat and I exercise regularly. Recently I had an increase in my thyroxine to 75mcg and my tummy bloated so badly I looked pregnant. GP has dismissed all this and said he didn't know what it was! I spoke to a rude woman on the phone at British Thyroid Foundation who was extremely rude and unhelpful. She said it wasn't the medication and blamed it on my thyroid! How can it be me when my weight has always been the same? I've never had problems like this before and the more sites I've visited on the net, I've actually found that so many people are unhappy on thyroxine and a lot of them experience bloating and weight gain. so something definately is taking place inside us and the Doctors are ignoring it. Its this medication thats making us worse and we are their guinea pigs and in the years to come they will admit they are in the wrong. There are so many thyroid sufferers and it's all about fobbing us off on cheap stuff. Well all those who don't care about us may it happen to them so they realize how and what we have to go through every single day. I am looking into alternative natural medications and am trying to also change my diet to help. We are stuck cos thyroxine is for life. We are all in the same boat and we have to raise this issue. A good website is thyroiduk.com
The good thing is we are all doing our research into this matter and more we are knowledgeable in this matter the better it is for us. I know Armour works for a lot of people but I can't take Armour.
From an unhappy hypothyroid sufferer.

Since i have been on levothyroxine for 8 month i have felt like my heart is going to give out and had it checked and hair is thinning big time my neck has been swollen 2 times it size and hard to swallow .it also has made my legs and feet hurt almost to point of feeling swollen and unable to walk feel worse than ever always have some kinda problem needing dr. attention since started Sandoz Levothyroxine

I started on 50 MCG of Levothyroxine last late May, due to a slightly underactive thyroid. The sides effect I am experiencing that is troubling me the most is that my hair is thinning dramatically. No bald patches, just thinning, and I had thin hair to begin with, so that makes it even more bothersome. I've also noticed that hair has completely stopped growing on my lower legs and upper thighs, and my eyebrows have thinned also. According to my doctor, my latest blood tests indicated that my thyroid levels were in ideal range now, and thinning hair isn't a side effect of the levothyroxine. I've read that it is, unless my thyroid levels still aren't ideal..and the levothyroxine is making my hair thin more than usual when in conjunction with the hypothyroidism. I'm also taking 25 mg of toprol to control tachycardia. If anyone could give me some advice, I'd really appreciate it! I'm at my wit's end as it my hair.

I took Synthroid for about two years for my hypothroidism, it really helped me to feel better and get my weight more on track. Since I have moved to a different state, thus a new doctor, I have been taking the generic for synthroid (levothyroxine). This has been for about 6 months. Since I went off the pill three months ago, I have not had my period. I just had my TSH level checked and it is normal on the generic, but I still haven't gotten my period. Can anyone help me??

RE: the new, generic levothyroxine drug, manufactured by SANDOZ: Theis generic drug was only approved in the summer of 2004. Has any tried it like me, and suddenly had terrible muscle/ joint pain and weakness? Does anyone know who to contact about this?

I have already entered side effects but I forgot to mention that I am taking a pill with two medications in it one is called levothyroxine and I am also taking 50 mcg of this medication.

I've been taking Synthroid (Levothyroxine) for about 17 YEARS. I was diagnosed with Grave's Disease, and opted for the radioactive iodine. After two years of trying to control the disease with PTU (which has serious bone marrow depletion side effects) I decided to go for the one thing I knew would work. Of course, the treatment with the radioactive iodine is very tough to estimate, and I went from hyperactive to hypoactive. As a result, I'll take 200mcg (0.2mg) for life.

I think it's important to understand that Synthroid is not a drug. It is a hormone. When you take Synthroid, you're engaging in hormone replacement therapy (HRT). You really won't experience side effects from the hormone, but you will experience problems if the amount of hormone is not within a "normal" range. Too much or too little will be a problem for anyone. What's critical here is to take the hormone at the same time every day (without food -- calcium will block its absorption), and monitor your hormone level frequently to establish a solid baseline.

The hormone will take days, or even weeks to reach its peak, and the duration is variable. BECAUSE IT'S A HORMONE, TAKING MORE OR LESS THAN IS NECESSARY WILL PRODUCE UNDESIRABLE RESULTS. Any "side effects" are really the result of improper dosing.

Having said all of that, I've never had a problem with Synthroid -- once my optimal level was determined. I worked closely with my MD and together decided that I was best at the upper side of "normal." I've made only one change in the 17 years, and that was to increase the dose.

Here's something to consider: If it weren't for this hormone, and the science behind HRT, I probably would have died years ago.

I've been on levothyroxine for 3 months now. I have anxiety at night while trying to fall asleep. In the morning my hands feel so tight and are a bit swollen. My right knee and calf have started now too. My feet hurt when I get out of bed. After about 10 mins of walking they feel better. My face is also a bit puffy in the morning and I look tired all the time. I have pains on the right side of abdoman, just under my ribs....Is this normal? Could it be my liver from the meds?

Hi everyone,
Just some info concerning Levothyroxine:
1/ Starting doses vary depending on your doctor's method,
I give 150ug then bring it down if necessary
2/ Anxiety problems are due to pre-existing psychological problems and not the molecule; if you're feeling over anxious you need to consult a therapist, the fact that the drug increases basal rate brings this out more manifestly
3/Hair loss is a symptom uniqueley of Hypothyroidism and not of the drug, as is weight gain

Take Care all
