Why this happens
Lercanidipine is a calcium channel blocker used for high blood pressure, and levothyroxine is a hormone replacement for an underactive thyroid. They are processed by different pathways in the liver and do not compete for absorption or excretion.
What you should do
You can continue to take both medicines as prescribed by your doctor. It is usually best to take levothyroxine on an empty stomach, first thing in the morning, at least 30 to 60 minutes before breakfast or taking other medications like lercanidipine, to ensure it is absorbed properly.

Patient picks for Drug interactions

Can I take Esomeprazole and Trazodone together?
Esomeprazole may reduce the amount of trazodone that your body absorbs. This could potentially make trazodone less effective at treating your symptoms (such as depression or sleep issues). Additionally, both medications can rarely affect the electrical activity of your heart, though this risk is generally low.
