I started Cymbalta two days ago. The first dose (30 mg.) was fine, no side effects! Took my second dose last night and good golly! I started itching within 30 minutes and thought I wouldn't have any skin left. It was that intense! No hives, no rashes, just the itching! I finally took Benadryl to help with the itching. Is this a normal reaction? Do I need to contact my doctor before I take my next dose? Trying to decide how to proceed! Thanks for your help and wisdom.
