Can I take Lercanidipine and Levothyroxine together?

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 do not interfere with each other's absorption or metabolism. However, thyroid hormones naturally affect heart rate and blood pressure; therefore, changes in your thyroid dose might indirectly change how much blood pressure medicine you need.

What you should do

You can take these two medicines together. It is usually best to take levothyroxine on an empty stomach first thing in the morning (30-60 minutes before breakfast) and lercanidipine at least 15 minutes before a meal. Continue to have your regular blood tests to monitor your thyroid levels and your routine blood pressure checks.
