Side Effects of Patanol Eye Drops

Patanol is prescription eye drop used to treat allergy symptoms such as watery, itchy or red eyes. Patanol is an antihistamine that works by blocking the effect of histamine, which causes an allergic reaction. Patanol will only treat the eye symptoms caused by seasonal allergies. Doctors typically recommend that people with allergies put one drop in each eye twice a day at least six to eight hours apart. Contact wearers should not use Patanol while wearing their contact lenses.

Vision Side Effects

• Some people using Patanol will experience stinging or burning when the drops are applied, blurred vision, eye redness, tearing and swelling of the eyelids. These side effects usually are no cause for concern and do not need to be reported to your doctor unless they become bothersome.

Taste

• Some people using Patanol eye drops may notice that foods taste differently than they once did. This is typically temporary and is not usually anything to be concerned about.

Head Side Effects

Allergic Reaction

• As with all medicines, an allergic reaction is possible when using Patanol. Signs of an allergic reaction include difficulty breathing; swelling of the face, throat and mouth; hives and dizziness. If you suffer an allergic reaction, immediate medical attention is necessary.
