What should I watch for while taking prazepam?

Visit your prescriber or health care professional for regular checks on your progress. Your body can become dependent on prazepam, ask your prescriber or health care professional if you still need to take it. However, if you have been taking prazepam regularly for some time, do not suddenly stop taking it. You must gradually reduce the dose or you may get severe side effects. Ask your prescriber or health care professional for advice. Even after you stop taking prazepam it can still affect your body for several days.

You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how prazepam affects you. To reduce the risk of dizzy and fainting spells, do not stand or sit up quickly, especially if you are an older patient. Alcohol may increase dizziness and drowsiness. Avoid alcoholic drinks.

Do not treat yourself for coughs, colds or allergies without asking your prescriber or health care professional for advice. Some ingredients can increase possible side effects.

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