Navane Side Effects

What should I watch for?

Visit your doctor or health care professional for regular checks on your progress. It may be several weeks before you see the full effects of this medicine.

You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medicine 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 may interfere with the effect of this medicine. Avoid alcoholic drinks.

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

This medicine can make you more sensitive to the sun. Keep out of the sun. If you cannot avoid being in the sun, wear protective clothing and use sunscreen. Do not use sun lamps or tanning beds/booths.

This medicine can reduce the response of your body to heat or cold. Dress warm in cold weather and stay hydrated in hot weather. If possible, avoid extreme temperatures like saunas, hot tubs, very hot or cold showers, or activities that can cause dehydration such as vigorous exercise.

Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water may help. Contact your doctor if the problem does not go away or is severe.


Interactions with Medications

Other serious but rare side effects may also occur. Some of these side effects, including severe muscle stiffness, fever, unusual tiredness or weakness, fast heartbeat, difficult breathing, increased sweating, loss of bladder control, and seizures, may be the sign of a condition called neuroleptic malignant syndrome. You and your doctor should discuss the good this medicine will do as well as the risks of taking it.
