I stopped taking levothyroxine a few weeks ago and have started having red blood shot eyes that do not respond to eye drops of any kind. Allergy, dry eyes , etc. Can stopping levothyroxine cause red , watery eyes and if I restart taking it will the symptoms of the red eyes disappear? If so, how long will it take?

I am having trouble controlling my blood sugars since starting levothyroxine 150 mcg 2 weeks ago after having my thyroid removed, I am on diabetes medication and have been for years and it has been under control and now I am getting crazy highs and lows. Is anyone else having this problem? my Dr. tells me there is no interaction but when I looked it up online it said there was and by the way I am feeling I tend to believe what I read.. any information would be appreciated.. thanks! ## U also need T3 which is Cytomel (or the generic Liothyronine SOD); this is to counter balance the T4 Levothyroxin u've bn taking. The only med that has both is Armor thyroid natural glandular which is hard to come by. ## You may also ask for Synthroid instead of the generic version, Levothyroxine. I kn...

Levothyroxine and Ringing in the Ears
12 Replies RSS
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 ...

I don't feel so confused anymore. Now I know all of you are going through the same thing. My doctor put me on 50mcg of Levothyroxine about a month ago and I have gain 8 pounds! I get short-breathed and winded REALLY easily when working out. I used to go to the gym for 2 hours, now I can't make it longer than 30 minutes. I wake up ALL the time with tingly fingers because my hands have fallen asleep. I have headaches, I feel 100 times more lazy than before...and it's supposed to help your energy, not drain it. I e-mailed my doctor today, this is not making me happy. Not to mention I now have an acne type rash that burns like hell on my chin and I've always had clear skin. If this drug is supposed to make you feel better it sure as sh*t isn't working for me. I feel like...

swelling in legs and feet levothyroxine
87 Replies RSS
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...

Afraid to take Levothyroxine because of reviews
4 Replies RSS
I've just been prescribed Levothyroxine 75mcg. I've been reading all the horrible reviews and am afraid to take it. I didn't have any symptoms of hypothyroidism except being overweight. I went to the dr for something totally different. I was overdue for routine blood work. Came back as this: TSH was 75.320, T4 free below normal 0.49, antibody 2250, T3 normal. I'm getting a biopsy on a nodule on Monday. Dr wants me to start on 75mcg Levothyroxine. I went the internet and have read horror stories. I don't have any symptoms of hashimotos thyroiditis (my diagnosis). In fact my symptoms mimic hyper insomnia, caffeine sensitive. I work 3rd shift. I've read the best time to take it is at night before bed. My pharmacist says in AM 30min before other meds. Neither of thes...

thyronorm overdose

A friend has taken 20 pills of thyronorm 25mcg out of hysteria.. What might be the repercussions? Please reply urgently. ## If you have reason to fear for the life and health of a loved one, you should contact your nearest emergency services or take them to the nearest emergency department, rather than posting online and waiting for an answer. And overdose of any medication is dangerous and risks death, organ damage and other serious health repercussions. High doses of the Levothyroxine in this creates the risk of seizures, strokes, heart palpitations and extremely high blood pressure. Even if she showed no ill effects, at the time she took them, she needs to see a doctor, because she could have done other damage to her body. How is she doing? ## I take 50mcg thyronorm daily.What if i t...
