Synthroid Overview

thyroid meds and high blood pressure
My drug store has switched my thyroid manufacturer from Mylan to Lanne. Since taking the same dosage of 88 mcg, my blood pressure has gone up considerably and I don't normally have high blood pressure. I have some of the older ones and have taken them for the last 3 days and my bp is back to normal. Is this just a coincidence or should I talk to the drug store? I also feel jittery in the neck area. I had the radio active iodine treatment 3 years ago. I feel like my thyroid is out of wack again. I don't have an appointment with my endocrinologist for 3 more months. ## I have been taking a 125mg synthroid and have gain extremely weight! I have to be cleared to have surgery but i think my levels off do you think i will Be cleared? Since i have gain so much weight does this mean my ...

Synthroid and Levothyroxine tablets taste just like SUGAR!
I took levothyroxine tablets for over 2 years then stopped. Why did I stop? Because they did absolutely nothing for me -- I kept gaining weight and continued to have all the same symptoms I had prior to taking them. BUT, the most important reason I stopped taking them was because I chewed a tablet (out of mere curiosity) and it tasted just like SUGAR! Oh so sweet. Hmmm...so why do they make a tablet taste like sugar when the instructions are to swallow it whole and NOT suck or chew it? (because they don't want you to discover it tastes like sugar). I believe that Levothyroxine and Synthroid (& most likely all other medication like these) are just SUGAR and that we are all being greatly DECEIVED. I recently went to my GP and she urged me to go back on Levothyroxine for my underac...

Synthroid sweet taste
Idk where to start and after taking my morning synthroid 0.075mcg it's so sweet. I get my prescription filled via mail-order at OptumRX. I have been using them for a year and a half since I changed insurance. This is when I started noticing the sweet taste. I'm thinking they are sugar pills or placebos. My weight just keeps slowing going up up up! And I CAN'T get it off. I am Diabetic with HBP and I have tried to get my dr to increase my synthroid but she won't. So this morning (which I know was wrong) I ended up taking a total of 4. I'm telling you it's some form of sugar! I see this same question over and over but it's like the question is NOT properly answered! What's going on with our meds? The pharmaceutical companies already make a killing on prices...

What does 100 MCG mean vs 0.1 MG?
I ran out of synthroid. It shows 0.1MG. I got a temporary bottle that shows 100MCG. Are they the same? ## Hi Lucille, Conversion tools verify that 100mcg (micrograms) is actually equal to 0.1mg (milligrams), so you should have nothing to worry about as far as taking the correct dosage is concerned. If you were given the temporary bottle by another pharmacy, that could explain why they used a different measurement than you were used to seeing. I hope this helps! ## Do you have to eat when taking leverothryroxin? 0.1 mg ## Hi. I am taking methylcobalamin 500 MG inj. every two weeks, but when you convert mg to mcg you get very high numbers. I am concerned that I am talking too much. Please help! Thank you ## You need to have an empty stomach. The best is to take it 1/2 before you begin you...

combitic global caplet tiroy-100
I just received a refill for what is supposed to be a generic for Synthroid in blister packs. The generic name on the packet is l-thyroxine sodium and looks like the name brand is Tiroy-100 and indicates it is manufactured by Combitic Global Caplet. The pill itself is small pale orange round shaped. There are no markings on the pill. I went to their website, which is very low rent looking, to look for a photo of their pills to make sure it was authentic and l-thyroxine sodium, Tiroy-100, or thyroid meds do not turn up as being manufactured by this company. Does anyone know if what I received is a good brand? Now I'm afraid to take them. ## No answer for you, but I ordered 200mg and just received it. Have you taken it? If so, how do you feel? ## has anyone used albendazole tablets IP...

Synthroid (Levothyroxine)
I'm taking 137 mgs right now but when my thyroid was down the Dr. gave me a different mg level, but I can't remember if this is what it was, but it sure gave me energy and I lost weight, but then he changed it and said that I'm where I should be and if I continued it I would get osteoarthritis as the dr said that I'm right on the borderline. I wish I could remember the mgs, because I felt so good and didn't have any problems on that mg level and I ask him if I could go back on it and he said no. Thank You Linda ## Well, there is, of course, no way for us to know for sure, what that dosage was, but I am betting you just hit a dosage that worked better for you than your current one. Whether it was a higher or lower dosage, our bodies do sometimes do better with a certa...

thyroxine sodium tablets 100 mg instead of synthroid 75 mcg
My wife is taking Thyroxin Sodium 100 mg for thyroid manufactured by GlaxoSmithKline India. Now I am in Canada and was taking the same with the consultation of the Doctor. Now the test is done and the thyroid is low. Now the doctor recommended Synthroid 75 mcg. My question is that whether I can take Throxin sodium instead of synthroid. ## Hi Subhash, Based on my research, Synthroid contains Levothyroxine; which is a synthetic version of the thyroid hormone thyroxine. Thyroxine is the natural hormone that is secreted by the thyroid gland. I can understand why you prefer the Thyroxine since it's not synthetic, but if your doctor suggested that you take the Synthroid (75 mcg) I'm sure he/she's just trying to do what's in your best interest. Nonetheless, if you like how the ...

small round yellow pill with flint onone side and 100 on the other
Small round pill with flint 100 on it ## This is Synthroid 0.1mg. It is used for people who have problems with their thyroid. ## Yes i take that dose myself, i actually take 2 doses between 1mg and 88mg. My thyroid doctor is trying to get me on the right dose right now for my tsh level. I want to be on 1mg, cause i feel my body works better with that dose but he feels that is too high for me. Because i had cancer in my thyroid before it was removed and my tsh is still high but that is his opinion against mine, its doctors against patients as usual. ## This is correct, the tablet is manufactured by Knoll Pharmaceutical Company and they list it as containing 100mcgs of Synthroid, which is used to treat thyroid disorders. The FDA lists its typical side effects as possibly including nausea,...
