What is Levothyroxine?

I have just started on levothuroxine 50mcg. I have noticed bright yellow urine as well as feeling very shaky (like I drank too much coffee) but also out of it. Also, last night I had a hard time going to sleep as my heart was beating very hard (not fast though). Is this normal when adjusting to the new hormone or could my dose be too high?

doctor1 MD

Hello Amelia and thanks for the query
Hypothyroidism is one of the cause for increased heart rate. But as you have started treatment for that hope that it will resolve as your thyroid level came back normal. Other reason for the increased heart rate may be stress or anxiety.
For urine problem...

doctor1 MD

2. since you are taking it for last 5 years, thus is/are there periodic evaluation after 6- 8 weeks to monitor drug response?

31 days and they had to burn my throat to stop bleeding. I need vit K 10mg before and after surgery even getting a tooth pulled.

Ezitimibe(drug for cholesterol) can cause muscle aches but other
alternative drugs such as statins still cause more muscle aches.
Also the combination of acetaminphen with codeine is underpower painkiller for your arthritis.In my...

Hi, My doctor has advised me to take 100 mcg Levothyroxine . So I took two tablets of 50 mcg each day before the breakfast. (In fact, I use 2 x 50 mcg tablets per day, instead of buying new 100 mcg tablets) I see in Merck s drug manual that 2 x 50 mcg is smilar to 100 mcg. But, since I am not sure, I just want to ask that Does two 50 mcg pills have the same effect as one 100 mcg pill? Does it make any problem to take two tablets every day?

doctor1 MD

yes 2 50mcg tablets will have the same effect as the 100mcg tab, only thing is if u take one tab its more comfortable than taking two tablets

I have today been prescribed with 50micrograms of levothyroxine . I have many of the symptoms and one blood test two months ago was slightly abnormal and the most recent one normal! I had a full blood screen done showing no other problems but my presenting symptoms. I would like to know what time of day is best to take it, will it help my snoring and will I put on weight which I really cannot afford to do? I m 52 and female. Thank you.

doctor1 MD

Hi there, thanks for asking. it can help you to lose your weight. You should also be more active when you find better energy after several weeks following taking the medication. It can help for snoring since hypothyroidism is one of the causes for sleep apnea, and losing weight will also help. If...
