Can I take Levothyroxine and Omeprazole together?

Why this happens

Levothyroxine needs a highly acidic environment in the stomach to be absorbed properly into your body. Omeprazole works by reducing stomach acid, which can prevent the levothyroxine from dissolving and entering your bloodstream effectively.

What you should do

You should ideally take levothyroxine on an empty stomach, at least 30 to 60 minutes before breakfast or taking other medications like omeprazole. If you are starting, stopping, or changing your dose of omeprazole, tell your doctor. They may need to perform a blood test (TSH test) to check if your levothyroxine dose needs adjusting.
