  • stop taking one of the medications,
  • change one of the medications to another,
  • change how you are taking one or both of the medications, or

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Medications other than those listed above may interact with Fluphenazine. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the Nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.

Fluphenazine Warnings

Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Fluphenazine.

Abnormal heart rhythm: Fluphenazine may cause or increase the risk for a certain type of abnormal heart rhythm called QT prolongation. Other medications can also increase the risk of QT prolongation when taken together with fluphenazine decanoate. If you experience symptoms of an abnormal heart rhythm such as dizziness, heart palpitations (fast, pounding, or irregular heartbeat), fainting, or seizures, stop taking Fluphenazine and get immediate medical attention.

Blood Clots: Fluphenazine may increase the chance of blood clot formation. If you have a history of clotting you may be at increased risk of experiencing blood clot-related problems such as Heart Attack, stroke, or clots in the deep veins of your leg.

If you experience symptoms such as sharp pain and swelling in the leg, difficulty breathing, chest pain, blurred vision, or difficulty speaking, contact your doctor immediately.

Blood counts: Fluphenazine can decrease the number of neutrophils (a type of white blood cell that helps fight infection) and platelets (which help your blood to clot). Your doctor will do blood tests to monitor this. If you notice any signs of infection (e.g., fever, chills, or sore throat) or unusual bleeding or bruising, contact your doctor immediately.

Drowsiness/reduced alertness: Especially in the first few days of treatment, Fluphenazine may impair the mental and physical abilities required for driving a car or operating heavy machinery. Avoid these activities until you know Fluphenazine does not affect your ability to perform them safely. Avoid drinking alcohol while using Fluphenazine, as it can produce extreme drowsiness.

Heat exposure and sweating: Fluphenazine decanoate may prevent the body from cooling when overheated by reducing your ability to sweat. Avoid becoming overheated when using fluphenazine decanoate.

Involuntary movement: Like other medications to control symptoms of schizophrenia, fluphenazine decanoate may cause rhythmic involuntary movements, known as tardive dyskinesia. Tardive dyskinesia is more likely to occur in women and seniors. These movements may involve only the tongue, face, mouth, or jaw, or they may include the extremities and trunk. Tardive dyskinesia is not reversible for some people. Report involuntary movements including sticking out the tongue, puckering mouth, or chewing movements to your doctor as soon as possible.

Kidney function: Fluphenazine decanoate may cause decreased kidney function and should not be used by people with kidney disease. Your doctor may want to regularly monitor your kidney function with blood tests when you first start taking fluphenazine decanoate to monitor for reduced kidney function.

Liver problems: Fluphenazine decanoate may cause liver problems. Your doctor may want to test your liver function with blood tests regularly while you are taking Fluphenazine. If you notice any signs of liver problems such as yellowing of the skin or whites of the eyes, nausea, vomiting, diarrhea, loss of appetite, weight loss, dark urine, or pale stools, contact your doctor as soon as possible.

Low blood pressure: Fluphenazine can cause low blood pressure. If you have heart disease, disorders of the blood vessels in the brain, or are having surgery, discuss with your doctor how Fluphenazine may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Fluphenazine, and whether any special monitoring is needed.

Neuroleptic malignant syndrome: Very rarely, fluphenazine decanoate has been reported to cause a severe reaction called neuroleptic malignant syndrome. If you or someone in your family who is being given fluphenazine decanoate develops symptoms including high body temperature (above 38°C), sweating, rapid heartbeat, severe muscle stiffness, and change in alertness, seek emergency help immediately.

Seizure disorders: Seizures have been reported by people who are taking fluphenazine decanoate. If you have seizure disorders, discuss with your doctor how Fluphenazine may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Fluphenazine, and whether any special monitoring is needed.

Sun: Fluphenazine makes you more sensitive to the harmful effects of sunlight.

Tremor and stiffness: As with other medications used to treat schizophrenia, fluphenazine decanoate may cause tremors or stiffness, or difficulty beginning purposeful movement. If this occurs, report it to your doctor as soon as possible.

Vision changes: Fluphenazine decanoate has been reported to cause changes in vision. Tell your doctor about any changes as soon as possible.

Withdrawal: Suddenly stopping Fluphenazine can cause withdrawal symptoms such as nausea, vomiting, dizziness, and shaking. Do not stop using Fluphenazine unless recommended by your doctor.

Pregnancy: Fluphenazine should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking Fluphenazine, contact your doctor immediately.

Breast-feeding: It is not known if fluphenazine decanoate passes into breast milk. If you are a breast-feeding mother and are taking Fluphenazine, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of Fluphenazine have not been established for children.
