Special warnings about Haldol

You should use Haldol cautiously if you have ever had breast cancer, a severe heart or circulatory disorder, chest pain, the eye condition known as glaucoma, seizures, or any drug allergies.

Temporary muscle spasms and twitches may occur if you suddenly stop taking Haldol. Follow your doctor's instructions closely when discontinuing the drug.

This drug may impair your ability to drive a car or operate potentially dangerous machinery. Do not participate in any activities that require full alertness if you are unsure of your reaction to Haldol.

Haldol may make your skin more sensitive to sunlight. When spending time in the sun, use a sunscreen or wear protective clothing.

Avoid exposure to extreme heat or cold. Haldol interferes with the body's temperature-regulating mechanism, so you could become overheated or suffer severe chills.
