the answer to your question depends on a lot of information you didn't include. i'll try to give you some general guidance. in the united states levothyroxine is a regulated drug. you can't obtain it without a prescription. so i'm wondering if you mean you took someone else's prescription medicine (which is always a bad idea) or if you obtained some sort of "natural supplement" type product that claims to contain levothyroxine (or a related product dessicated pork thyroid). levothyroxine is a thyroid hormone. thyroid hormones are important for regulating many body functions. people who have had their thyroid gland removed (or destroyed with radioactive iodine) or who don't produce enough thyroid hormone generally receive therapy with supplements like levothyroxine. no one should take levothyroxine (or any other thyroid hormone) unless they have been diagnosed with a thyroid disorder. taking unneeded thyroid hormone can cause problems with the thyroid gland and can interfere with many bodily functions. so in short taking a single 50mcg dose of levothyroxine on a one-time basis probably is no cause for alarm. but do not take this medication unless it has been prescribed for you by a health care provider. hope this helps! it was given in a pass med for a weekend trip and was not for me. i took the medication then realized it was not mine. pharmacy put someone elses in the bag. i cannot find where there is any real adverse reactions to a single dose of it and since i have not had any of the alergic reactions noted on the label i figure i am ok. dont want to make a trip back to doctor if not necessary. thanks for information.
took a dose of 50mcg levothyroxine can this cause harm? . should i be concerned since it is a natural hormone produced? effects if any it may cause?
