ask your pharmacist

Are there any drug interactions with Penlac?

Although there are no studies of drug interactions with Penlac, it's probably unlikely they exist, as very little medication is absorbed from the nail into the body. However, you should talk to your doctor before using Penlac if you are currently taking oral drugs to treat your nail fungus.
