Unusual: Swollen lips or angioedema is rarely caused by seasonal allergy but can occur. There are many other causes and a thorough evaluation is needed.

Yes: Swelling of your lips is caused by histamine released from mast cells when an allergan binds to it. Taking an antihistamine like Claritin or Benadryl (diphenhydramine) should help minimize the symptoms.
