What should I watch for while taking haloperidol?
You may get dizzy or drowsy. Do not drive, use machinery, or do anything that needs mental alertness until you know how haloperidol affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol can increase dizziness and drowsiness. Avoid alcoholic drinks. You can get a hangover effect the morning after a bedtime dose.

Do not treat yourself for colds, diarrhea or allergies. Ask your prescriber or health care professional for advice, some nonprescription medicines may increase possible side effects.

Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water will help. Be careful when brushing and flossing your teeth to avoid mouth infections or damage to your gums. See your dentist regularly.

If you are going to have surgery tell your prescriber or health care professional that you are taking haloperidol.

Avoid extreme heat or cold. Haloperidol can stop you sweating and increase your body temperature. It can also make your body unable to stand extreme cold. Avoid hot baths and saunas. Be careful about exercising especially in hot weather. Dress warmly in cold weather and do not stay out long in the cold.

Haloperidol may make you more sensitive to sun or ultraviolet light. Keep out of the sun, or wear protective clothing outdoors and use a sunscreen (at least SPF 15). Do not use sun lamps, or sun tanning beds or booths. To protect your eyes wear sunglasses even on cloudy days.

Where can I keep my medicine?
Keep out of the reach of children.
