Will Swelling from Allergies Harm Eyelid Surgery Healing?

Allergies will not harm the blepharoplasty incision. From a comfort standpoint, make sure your allergies are under control with antihistamines and cortisone nasal sprays. Antihistamines such as Claritin can be purchased over the counter, but the cortisone nasal sprays need to be prescribed by your physician.

Time saver,
Swelling from any source (allergy, medication, infection, etc) will prolong the healing time following any surgery. The more extensive the surgery and the more severe the swelling source, then the more prolonged the healing period.
Fortunately, plastic surgery limited to the upper eyelid with typical swelling most patients with allergies complain about should not be problem. Most patients will not notice a difference in the recovery period. Blepharoplasty eyelid incisions heal relatively quickly. Speak with your plastic surgeon performing the surgery and your allergist to best manage your specific allergies in the perioperative period. Best of luck.
