Levothyroxine side effects

I was recently diagnosed with an underactive thyroid. I have been taking levothyroxine for almost two weeks. For the last four or five days I have had a weird feeling. It is hard to explain. I don't really feel dizzy but I get a strange feeling in my head. I guess you would describe it as a head rush. Has anyone else had this feeling and will it go away as my body adjusts to the levothyroxine? ## yes i would get that every morning after i took my pills and drank coffee. I think its inmortant to eat a little over an hour after to avoid the dizziness. It does go away though. ## Levothyroxine Info and Side effects Click Here ## my pharmactist changed my thyroid pills because my insurance doesn't cover my other ones. I am cold all the time again and i am dizzy. I came home from work...

Carbimazole and Levothroxine

Hi there. Why has my doctor prescribed both Carbimazole and Levothroxine to be taken on the same day? ## How were your thyroid levels? Sometimes, multiple medications might be prescribed to help lower levels as fast, and as safely as possibly. The NIH lists the typical side effects as possibly including nausea, dizziness, headache, weight changes, mood changes, and hair loss.

Swelling in legs and feet levothyroxine

I just started taking Levothyroxine 2 wks ago my legs and feet are swollen so bad by nite I can barley walk. They go down a little at nite but swell back. I am taking 25mcg and I am afraid to continue taking this med. Has any one else had this problem? ## Have you contacted your doctor? It sounds like you might be having a bad reaction to this medication and it may not be the right one for you, or may be too high of a dosage. Generally, the symptoms of a dosage being too high will start to manifest 6 days or so, after you start taking it and this type of fluid retention can be one of them and there is a chance that it could lead to congestive heart failure, if that's what's causing it and it isn't rectified. You should really contact your doctor immediately. ## I am on medic...

Hoarseness Side Effects?

I was diagnoised with hypothyroidism last December and was put on Levothyroxine (75mcg). Overall I have been feeling better and have more energy. But unlike most other people with underactive thyroids I was not overweight and since going on Levothyroxine have lost 10 pounds and am continuing to lose weight. I also have developed hoarseness which gets worse as the day goes on. Question-the weight loss is a common side effect of the medication-but has anyone heard of hoarseness? My thyroid levels were tested a few weeks ago and are now normal. ## Yes, I have noticed sore throat and hoarseness also on generic levothyroxine 75mcg. I finally tried not taking it for a couple of days and the sore throat and hoarseness went away. Started taking it again and voila, the sore throat and hoarseness...

Sandoz Levothyroxine

Recently filled a prescription for Levothyroxine 150 mcg and noticed a very fowl smell and ultimately a slightly different taste when taking it. One side of the pill is marked with "150" and the other side with "GG338." We questioned the pharmacist about this and they opened a new bottle that smelled the same to us, but she didn't smell anything so nothing was done. I know Levoxyl was discontinued for a while for this very problem. Is there any information out there about this Sandoz product? ## If you had a chance to read the FDA recall information, the odor it was recalled for was actually due to a problem with the absorbent canister that was packaged in the bottles, not the pills themselves. However, the odor was not found to cause any adverse health issues, or pr...

Solmux Capsule

How many times do I have to take Solmux? And for how many days do I need to take these capsules? Please advise. Thank you. ## Hi Ellen, Solmux contains the active ingredient Carbocisteine, which is used to help thin the mucous caused by conditions such as allergies and COPD. The dosage and administration guidelines for this medication state the following: For adults and children over age 12, one capsule of Carbocisteine (Solmux) should be taken with food every 8 hours.

Levothyroxine and Ringing in the Ears

I was recently diagnosed with Hypothyroidism after having my thyroid tested and my TSH was 5.9. I have been taking Levothyroxine since the end of June. The middle of July I started having non-stop ringing in my ears and still continues. I also have experienced severe hair loss and cannot put weight ON.

Please help. Is the levothyroxine making me crazy?

I was diagnosed with hypothyroid about 7 yrs ago. I was taking 50 mcg of levothyroxine up until now. I am currently 29 weeks pregnant and my new doctor put me on 125 mcg. My doc says i have to be on a higher dose during pregnancy or the baby will be born with birth defects or have learning disabilities. The road has been really rocky. My moods have been up and down, i suffer from severe depression, mood swings, horrible anger, memory loss, bad anxiety attacks and fear of loosing myself. I litterally feel crazy. I asked my doctor and there is nothing she can do except put me on some antidepressant. I dont think i need that and i dont really like takin meds like that. I absolutely think the levothyroxine is making me worse. I feel suicidal and thats not something i want to feel esp. durin...
