What is the most important information I should know about atropine?

Use caution when driving, operating machinery, or performing other hazardous activities. Atropine may cause dizziness, drowsiness, or blurred vision. If you experience dizziness, drowsiness, or blurred vision, avoid these activities. Use alcohol cautiously. Alcohol may increase drowsiness and dizziness while you are taking atropine.

Avoid becoming overheated in hot weather. Atropine increases the risk of heat stroke because it causes decreased sweating.

What is atropine?

Atropine produces many effects in the body, including relief from spasms of the gastrointestinal tract (stomach and intestines), the bladder, and the biliary tract. This is helpful in controlling conditions such as colitis, spastic bladder, diverticulitis, infant colic, renal and biliary colic, peptic ulcer, and irritable bowel syndrome.

Atropine also reduces the secretions of many organs, thereby helping to control conditions such as excessive stomach acid production and excessive secretion from the pancreas; to reduce secretions of the nose, lungs, salivary glands, and stomach before surgery; and to help dry up excessive mucus production associated with diseases, infections, and allergies.

Atropine is used to treat the rigidity, tremor, excessive salivation, and sweating caused by Parkinson's disease.

Atropine also has effects on the heart. It is used during surgery to maintain proper heart function, during emergencies involving the heart, and to treat certain heart disorders.

Atropine is used to control laughing and crying episodes that are caused by brain tumors.

Atropine also has effect on the eyes and is available in an ophthalmic (eye) formulation.
