Yes, you can use Ezehron Duo and Drovelis at the same time, especially if you are using the medication as directed by your doctor. 

There are no contraindications to the concomitant use of these drugs. Ezehron Duo lowers LDL cholesterol and Drovelis is a hormonal contraceptive, so they act on different body systems and should not interact with each other.

I encourage you to inform your attending physician about all the medications and dietary supplements you use, which will allow you to choose safe and effective pharmacotherapy. Only a doctor can assess whether the combination of these drugs is safe and appropriate for your current clinical condition.
