Hives and Facial Swelling Just Started After 2 Years on Propecia

Hello Doctor,
I have been using propecia for close to 2 years now with great results. The hair got thicker and I am very thankful for it. But for last 6 months I have been getting hives over my entire body, initially I thought it was food. So I kept track of what I ate but it showed no consistency. I had hives almost every other day. Then I stated taking an antihistamine but the hives continued to get more severe and my lip started swelling up. I went to allergist and everything (got blood test). Nothing showed. Recently I started getting swollen eyes as well. I finally tried stopping propecia and no hives, swollen lips or eyes for almost 10 days now. What can I do now? I really think propecia works great and I want to keep taking it but the side effect is really bad. The lip swelling is really disfiguring. How can I get around this problem? Thanks

It sounds like you have developed an allergy to Propecia if your hives and swollen lips go away upon stopping the drug. I would like you to go back to your doctor or possibly your allergist and give them the information about stopping the drug, asking for an opinion. You are on a timeline here, as you can expect to see hair loss after stopping Propecia for about 2-3 weeks, so get those opinions in hand ASAP.

You may not be able to manage the allergic reaction which has dangers of progression and even more side effects. I am not your doctor, so this is just a general opinion not based upon an intimate knowledge of you and your situation other than what you wrote here.
