Synthroid and yellow tongue
My tongue is always yellow. It's not my oral hygiene. I have been on Synthroid for years. Could it be the cause? ## Hello, Donia! How are you? Is the only medication you take regularly? I didn't find anything specifically listed about Synthroid/Levothyroxine causing this, but there are so many things that can, including foods, beverages, and oral care items that it's hard to be sure. Ref: Medline Plus Synthroid Is there anything that you eat, or drink every day that might be causing it? Have you spoken to your doctor, or dentist about it?

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...

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 menstrual changes side effect
Hi, ever since I started taking synthroid my cycle got much longer and reproductive hormones tests did not come great (low FSH, low LH, high oestradiol, high prolactin). TSH and T4 is ok though so my doctor is happy with dose (and I'm waiting for referral to endo). I can't find anywhere if it's a side effect that goes away by itself as body adjusts or is there something really wrong. Feeling anxious but my wait to see endo could be a while. Anyone knows anything? They only say that hair falling out is a temporary thing (luckily don't have that!) But nothing about other side effects... ## Yes, menstrual, and hormonal, irregularities are a reported side effect of Synthroid, along with nausea, diarrhea, muscle weakness, and insomnia. So, things should improve, once your bod...

levothyroxin tab
I am allergic to the dye in the 112mcg Synthroid tablets. Does anyone know of a 112mcg that is white??? Levothyroxine ? I am now taking 2 pills on 5 days and 3 pills on 2 days. 50mcg each. ## I am allergic to the dye as well, and should be on 112 mcg. too. I like your idea of 2 pills (white..50 mcg.) for 5 days, and 3 pills for 2 days. So glad you posted your idea. Splitting the pills just doesn't work. If any Manufactures are reading this, please refrain from putting dyes in meds!!! Serious side effects can result, and the dyes make it difficult for some of us to take the proper dosage amounts that are prescribed. ## Your pharmacy should be able to provide you with a dye free option, though they may have to order a supply in for you, so it is best to make sure to alert them to the ...

Armor 60 Mg Vs Synthroid 0 112 Mug
I have been on synthroid for approx 11 years. Some of my symptoms never went away. Cold hands &feet, losing (it does grow back, but I have a million baby hairs on my head) hair, etc. I read somewhere that changing from a strictly T4 (Synthroid) to a T3T4 (Armour) thyroid medicine would help. My doctor gave me the new medicine Armour 1 GR (60mg). I was on synthroid 0.112MG). Did my doc give me too high a dose of the new amrour medicine? I want my symptoms to go away but I don't want to overdose. Help! ## I was on Synthroid 0.112mg and the Dr. put me on Armour Thyroid 3GR. which is 180mg. I would say that your dose is closer to the equivelant of Synthroid then mine. I don't know what my last TSH, T4 levels were so I hope thats why he gave me such a high dose... All I know is I...

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...

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 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...
