Most important fact about Stelazine

How should you take Stelazine?

If taking Stelazine in a liquid concentrate form, you will need to dilute it with a liquid such as a carbonated beverage, coffee, fruit juice, milk, tea, tomato juice, or water. You can also use puddings, soups, and other semisolid foods. Stelazine should be diluted just before you take it.

Special warnings about Stelazine

You should use Stelazine cautiously if you have ever had a brain tumor, breast cancer, intestinal blockage, the eye condition called glaucoma, heart or liver disease, or seizures. Be cautious, too, if you are exposed to certain pesticides or extreme heat. Be aware that Stelazine may hide the signs of overdose of other drugs and may make it more difficult for your doctor to diagnose intestinal obstruction, brain tumor, and the dangerous neurological condition called Reye's syndrome.

Tell your doctor if you have ever had an allergic reaction to any major tranquilizer similar to Stelazine.

Dizziness, nausea, vomiting, and tremors can result if you suddenly stop taking Stelazine. Follow your doctor's instructions when discontinuing this drug.

Tell your doctor immediately if you experience symptoms such as a fever or sore throat, mouth, or gums. These signs of infection may signal the need to stop Stelazine treatment. Notify your doctor, too, if you develop flu-like symptoms with fever.

This drug may impair your ability to drive a car or operate potentially dangerous machinery, especially during the first few days of treatment. Do not participate in any activities that require full alertness if you are unsure about your ability.

If you have any trouble with your vision, tell your doctor.

Stelazine concentrate contains a sulfite that may cause allergic reactions in some people, especially in those with asthma.

Stelazine can cause a group of symptoms called Neuroleptic Malignant Syndrome. Signs are high body temperature, rigid muscles, irregular pulse or blood pressure, rapid or abnormal heartbeat, and excessive perspiration.

Possible food and drug interactions when taking Stelazine

Extreme drowsiness and other potentially serious effects can result if Stelazine is combined with alcohol, tranquilizers such as Valium, narcotic painkillers such as Percocet, antihistamines such as Benadryl, and barbiturates such as phenobarbital.

If Stelazine is taken with certain other drugs, the effects of either could be increased, decreased, or altered. It is especially important to check with your doctor before combining Stelazine with the following:

Antiseizure drugs such as Dilantin
Atropine (Donnatal)
Blood thinners such as Coumadin
Guanethidine
Lithium (Lithobid, Eskalith)
Propranolol (Inderal)
Thiazide diuretics such as Dyazide

Special information if you are pregnant or breastfeeding

Pregnant women should use Stelazine only if clearly needed. The effects of Stelazine during pregnancy have not been adequately studied. If you are pregnant or plan to become pregnant, inform your doctor immediately. Stelazine appears in breast milk and may affect a nursing infant. If this medication is essential to your health, your doctor may have you discontinue breastfeeding while you are taking it.

Recommended dosage for Stelazine

ADULTS

Nonpsychotic Anxiety

Doses usually range from 2 to 4 milligrams daily. This amount should be divided into 2 equal doses and taken twice a day. Do not take more than 6 milligrams a day or take the medication for more than 12 weeks.

Schizophrenia

The usual starting dose is 4 to 10 milligrams a day, divided into 2 equal doses; doses range from 15 to 40 milligrams daily.

CHILDREN

Doses are based on the child's weight and the severity of his or her symptoms.

Schizophrenia in Children 6 to 12 Years Old Who Are Closely Monitored or Hospitalized

The starting dose is 1 milligram a day, taken all at once or divided into 2 doses. Your doctor will increase the dosage gradually, up to 15 milligrams a day.

OLDER ADULTS

Older people usually take Stelazine at lower doses. Because you may develop low blood pressure while taking this drug, your doctor will watch you closely. Older people (especially older women) may be more susceptible to tardive dyskinesia--a possibly permanent condition characterized by involuntary muscle spasms and twitches in the face and body. Consult your doctor for information about these potential risks.

Overdosage of Stelazine

Any medication taken in excess can have serious consequences. If you suspect an overdose of Stelazine, seek medical help immediately.

Symptoms of Stelazine overdose may include: Agitation, coma, convulsions, difficulty breathing, difficulty swallowing, dry mouth, extreme sleepiness, fever, intestinal blockage, irregular heart rate, low blood pressure, restlessness
