Have suffered from a low thyroid for about 3 years. I can tell when it needs to be tested again as I get very bad leg aches and bottoms of my feet hurt to touch the floor. However, when my dosage of Levoxyl is increased(has been doubled at one time), I suffer from several side effects. Night Sweats for 8 weeks then they quit and I quit menstrating. Has anyone else had those side effects? What are your physicians telling you?

I spent alot of time last night looking up the side effects of levothroid which also includes levoxyl, synthroid, etc. Here's a list of side effects that is standard from almost every site I visited:

What are the possible side effects of levothyroxine?

• If you experience any of the following serious side effects, stop taking levothyroxine and seek emergency medical attention or contact your doctor immediately:

· an allergic reaction (difficulty breathing; closing of the throat; swelling of the lips, tongue, or face; or hives);

· vomiting; or

· chest pain, irregular heartbeat, shortness of breath.

• Other, less serious side effects may be more likely to occur. Continue to take levothyroxine and talk to your doctor or try another similar medication if you experience

· tremor, nervousness, or irritability;

· headache;

· insomnia;

· diarrhea, changes in appetite, or weight loss;

· leg cramps;

· menstrual irregularities; or

· fever, sweating, or heat sensitivity.

• Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.


Me again, my guess is that the side effects you feel when your dose is increased is the adjustment period that your body goes through as it takes in the extra thyroid hormone. When ihad my dose increased this past June, it felt like a bumpy road .... lots of highs, some lows, very uneven for a time, then smooth. It was strange but after about 6 weeks, it was completely gone. That's just my opinion of what's going on. You can ask your doctor if you want a more educated guess! LOL! Hope you feel better soon.
