Fluphenazine Side Effects

What should I watch for?

Visit your doctor or health care professional for regular checks on your progress.

You may get drowsy, dizzy, or have blurred vision. 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 can increase possible dizziness or drowsiness. Avoid alcoholic drinks.

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.

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.

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.


Common and Rare Side Effects

Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.

Phenothiazines can sometimes cause serious unwanted effects. Tardive dyskinesia or tardive dystonia (muscle movement disorders) may occur and may not go away after you stop using the medicine. Signs of tardive dyskinesia or tardive dystonia include worm-like movements of the tongue, or other uncontrolled movements of the mouth, tongue, cheeks, jaw, body, arms, or legs. Another possible serious unwanted effect is the neuroleptic malignant syndrome (NMS). Signs and symptoms of NMS include severe muscle stiffness, fever, fast heartbeat, difficult breathing, increased sweating, and loss of bladder control.

Some side effects may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them:

After you stop using this medicine, your body may need time to adjust. The length of time this takes depends on the amount of medicine you were using and how long you used it. During this time, check with your doctor if you notice dizziness, nausea and vomiting, stomach pain, trembling of the fingers and hands, or any of the following signs of tardive dyskinesia or tardive dystonia:

Inability to move eyes

lip smacking or puckering

muscle spasms of face, neck, body, arms, or legs, causing unusual body positions or unusual expressions on face

Although not all of the side effects listed above have been reported for all of the phenothiazines, they have been reported for at least one of them. However, since all of the phenothiazines are very similar, any of the above side effects may occur with any of these medicines.

Other side effects not listed may also occur in some patients. If you notice any other effects, check with your healthcare professional.

Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.
