You should ask your doctor. As much as we would like to help you, your doctor would know what's best when it comes to medication.💊

If it is not too late, you should be just fine taking the two together. There are rare effects among people with cardiac issues, but even those are uncommon. You can go to drugs.com and type in the medications and the site will list the possible interactions.
