Hi Dear , As per your query you have urticaria after drinking beer , which not usually happen with you . Allergic reactions to beer are not unusual, although they are not common either . There can be many reasons for symptoms you mention in query like allergic sensitivity to content of alcohol like hops in beer ( as beer is made from some natural ingredients ) . Contents of alcohol can cause angioedema and urticaria . Well such type of condition should not be ignored because itca lead to anaphylaxis , which can be life threatening . I would suggest you to not to drink beer . drink plenty of water to flush out beer as quickly as possible and to keep yourself hydrate and take bendryl twice a day . Consult dermatologist without any delay . Doctor may give adrenaline shot along with anti inflammatory or steroid ointment . Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
