Can You Drink Coffee After Taking Thyroid Medication?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 21st, 2026.
No, you should wait at least 30-60 minutes after taking thyroid medication before drinking coffee. Coffee can significantly reduce the absorption of thyroid hormones like levothyroxine by up to 55%, making your medication less effective. The caffeine and other compounds in coffee interfere with how your intestines absorb the medication. Studies show that even small amounts of coffee consumed within an hour can dramatically decrease blood levels of thyroid hormones. For optimal medication effectiveness, take your thyroid pill with plain water on an empty stomach, then wait at least 30 minutes before consuming coffee, food, or other beverages.
