Most of the side effects of atropine are directly related to its antimuscarinic action. Dryness of the mouth, blurred vision, photophobia and tachycardia commonly occur with chronic administration of therapeutic doses. Anhidrosis also may occur and produce heat intolerance or impair temperature regulation in persons living in a hot environment. Constipation and difficulty in micturition may occur in elderly patients. Occasional hypersensitivity reactions have been observed, especially skin rashes which in some instances progressed to exfoliation.
Adverse effects following single or repeated injections of atropine are most often the result of excessive dosage. These include palpitation, dilated pupils, difficulty in swallowing, hot dry skin, thirst, dizziness, restlessness, tremor, fatigue and ataxia. Toxic doses lead to marked palpitation, restlessness and excitement, hallucinations, delirium and coma. Depression and circulatory collapse occur only with severe intoxication. In such cases, blood pressure declines and death due to respiratory failure may ensue following paralysis and coma.

Uses For Atropine
Ophthalmic atropine, homatropine, and scopolamine are used to dilate (enlarge) the pupil of the eye. They are used before eye examinations, before and after eye surgery, and to treat certain eye conditions, such as uveitis or posterior synechiae.
These medicines are available only with your doctor's prescription.
Precautions While Using Atropine
After you apply this medicine to your eyes:
- Your pupils will become unusually large and you will have blurring of vision, especially for close objects. Make sure your vision is clear before you drive, use machines, or do anything else that could be dangerous if you are not able to see well.
- Your eyes will become more sensitive to light than they are normally. Wear sunglasses to protect your eyes from sunlight and other bright lights.
These effects may continue for several days after you stop using this medicine. However, check with your doctor if they continue longer than:
- 14 days if you are using atropine.
- 3 days if you are using homatropine.
- 7 days if you are using scopolamine.
