Does levothyroxine cause acne

I have been taking 25mcg for about 6 weeks and feel much better, no weight loss, but no gain. I have developed acne on my chin and around the right side of my mouth...is this a side effect? Anyone else had this happen? ## ive been taking a 25mcg for a week now and am worried that i will develop acne. do many people get this ? ## I have been taking the same dosage as you for about 2 months and have had really bad breakouts EVERYWHERE that I didn't used to get. I now get them on my back, face, shoulders and neck. It's pretty gross and I've never had this problem before but I think it does have something to do with Levothyroxine. ## Hi, I am on thyroxine 4 weeks now and also have gotten acne on my chin and around the mouth. I am now 47 and have not had this problem since I was ...

Levothyroxine100mg is no longer working for me ?

Hi, my100mg levothyroxine tablets are no longer working for me.I have been taking these for 2 years with a gradual spiralling weight gain. I am now tipping 12 stone instead of a normal 10 stones.

However, I'm curious as to how old you are? If you've over 35, these same symptoms ...

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...

I have been taking 25mg of this crap for almost a year. Im 28 over weight and wondering if stoping this med suddenly with my docs concent is dangerous. Im gaining weight and not feeling any better. I also take colonzipam for anxiety metroprol for high bp and Norco for back pain im a smoker and weigh 290 before I only weigh ed 260 me and my doc are exploring the fact that I may not need this med at all or i need a different kind. So he said to stop for 2 months should i be worried about this decession? ## No, it is nothing to worry about. Your doctor isn't trying to steer you wrong. What have the test shown for your TSH results? That is what would let you know whether or not you need such a medication. ## First get some blood tests done. Get T4, T3 and TSH measured at least. If they ...

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. Is it okay to stop taking Levo to see if the ringing in my ears stop? I really don't want to be on this medication, but don't want to cause additional issues as I'm getting married soon. Appreciate any sound advice. ## I have been on levothyroxin for a good while now.i just had a week away and forgot my pills.BUT I feel good.i don't feel as tired I have less headaches.less noise/ringing ear noises.and basically feel better without my pills I don't think my doc will be ...

Levothyroxine 50mcg Tablet Recall

I recieved a letter from my health care provider saying that i cannot continue getting Levothyroxine 50mcg tablet that theres a recall on that medication.I want to know the reason for the recall. ## I can't find any updated recall information for it, but there was one reported on April 28th, for the 150mcg tablets, so it is possible that a problem was also found with this one and it was added under that same recall. There has been an ongoing problem with Levothyroxine products, which has created the need for the recall and this problem has actually been occurring since the 1990's. The problem is actually two-fold. 1) They have regularly found stability and potency problems with them, regardless of the manufacturer or dosage. Most of them did not retain their proper potency up to...

When I had my prescription for levothyroxine 75 refilled recently I immediately noticed a strange smell. Can you please tell me what it is? ## Hello, Joyce! How are you?

Is levothyroxine the same as thyronorm?

What are the benefits of thyronorm over levothyroxine? Do the symptoms like hair fall continue even after starting medication? ## They are the same, one is just a brand name and the other a generic name of the active ingredient. And yes, hair loss is a typical side effect of this medication, as reported by the U.S. FDA. You may also experience nausea, dizziness, headache, mood swings, and weight changes. Are you on any other medications? ## I took thyronorm for 26 years and switched to Levothyroxine after coming to the United States. Can you tell me whether it’s safe to proceed with Levothyroxine or move back to thyronorm? I have noticed a change in mood swings, hair loss as well as depression frequently with Levothyroxine. ## what does anyone know about Armour? I still have the v...

Levothyroxine and working in the heat

I have been on levo for 2 1/2 years. Started at 75 for about a year and a half. I got a new dr and dose was upped to 100, then 125 for last six months. I have also been dealing with menopause, I THINK. In the last 5 months I have had trouble falling asleep, jittery, nervous energy. I have worked outdoors in the heat with no problems. Now that I look back, I have had a hard time in the heat since I started levo. A couple months ago I weaned off of cymbalta and after those withdrawals were over, I started getting naseau and migraine. Has anyone else experienced heat problems? And is there a natural med for hypothyroidism? ## Hi Lisa, Sorry to hear about your situation. According to the US National Library of Medicine, "sensitivity to heat" is listed as a serious side effect of Lev...
