LEVOTHYROXINE (THYRIOD) MEDICATION
Many patients are concerned about the right “way” to take their thyroid medication. The pharmacist will usually instruct you to take it 30 minutes prior to eating breakfast. This is not necessarily true. It’s more important to take it the same time every day. Yes, it’s true that food may decrease absorption of the medicine, but your dose can be titrated so that it does not become a factor. It is also OK to take the medicine at nighttime-once again be consistent and take it the same time at least 4 hours after eating. There are some medications that can interfere with levothyroxine, and these should not be taken at the same time. Calcium, Iron, phosphate binders and even acid reducers, like Omeprazole, will decrease absorption. For those of you taking osteoporosis medications, it’s best to take thyroid pills 30 minutes after the osteoporosis meds.
Some patients ask about branded Synthroid versus generic levothyroxine. Basically there is no difference in the majority of patients. All generics must be BIOEQUIVALENT and is regulated by the FDA. The only thing I would advise is to recheck the TSH (thyroid test) 4-8 weeks after changing brands if you don’t feel “right”.
