My dermatologist prescribed me hydrocortisone valerate for my lips. is this weird?

Weird prescription: It doesn't sound strange. It is good practice to get all of your questions answered fully before you leave your doctor's office. If he or she doesn't want to answer them, find someone else quick. If you have questions when you get home, call them and give them 24h to get you an answer. Your own personal doctor is your best source of information.
