Common side effects include itching of the eye, itching, redness or irritation at the treated area and increased unwanted hair growth on other body areas. Less common side effects such as rash, difficulty breathing, swelling of the mouth, face, lips and tongue, dizziness, chest pain and headaches have been reported.
