Side Effects of Atropine Eye Drops

Optometrists and ophthalmologists sometimes use atropine ophthalmic eye drops to dilate the pupil before eye examinations. Atropine also is used to relax the eye muscles to relieve pain after surgery or when the patient has an inflammatory eye condition. Numerous side effects are possible, but most are rare.

Common Side Effects

• Atropine eye drops can cause blurred vision, and people should avoid driving if they experience this side effect. Another common side effect is sensitivity to bright light, because the pupil cannot react to light while under the influence of atropine. These side effects disappear as the medication wears off.

Other Side Effects

• Other common atropine side effects include eye irritation or stinging, eye redness, minor eyelid swelling and redness and dry mouth.

Serious Reactions

• Rare but more serious reactions to atropine eye drops call for medical attention. These include fever, irregular or fast heart rate, confusion and difficulty urinating.

Pediatric Side Effects

• Serious rare side effects that are more common in children than adults include hallucinations, irritability and unusual behavior. Infants may develop a swollen or distended stomach.

Allergic Reaction

• Another rare atropine side effect is an allergic reaction. Signs include difficulty breathing, throat closing, hives or rash and swelling of the face or mouth.
