Side effects of Stelazine in details
A side effect of any drug can be defined as the unwanted or undesired effect produced by the drug. The side effect can be major or in few medications minor that can be ignored. Side effects not only vary from drug to drug, but it also depends on the dose of the drug, the individual sensitivity of the person, brand or company which manufactures it. If side effects overweigh the actual effect of the medicine, it may be difficult to convince the patient to take the drug. Few patients get specific side effects to specific drugs; in that case, a doctor replaces the drug with another. If you feel any side effect and it troubles you, do not forget to share with your healthcare practitioner.
These symptoms are seen in a significant number of hospitalized mental patients. They may be characterized by motor restlessness, be of the dystonic type, or they may resemble parkinsonism.
Depending on the severity of symptoms, dosage should be reduced or discontinued. If therapy is reinstituted, it should be at a lower dosage. Should these symptoms occur in children or pregnant patients, the drug should be stopped and not reinstituted. In most cases barbiturates by suitable route of administration will suffice. (Or, injectable Benadryl®" may be useful.) In more severe cases, the administration of an anti-parkinsonism agent, except levodopa, usually produces rapid reversal of symptoms. Suitable supportive measures such as maintaining a clear airway and adequate hydration should be employed.
Motor Restlessness: Symptoms may include agitation or jitteriness and sometimes insomnia. These symptoms often disappear spontaneously. At times these symptoms may be similar to the original neurotic or psychotic symptoms. Dosage should not be increased until these side effects have subsided.
If this phase becomes too troublesome, the symptoms can usually be controlled by a reduction of dosage or change of drug. Treatment with anti-parkinsonian agents, benzodiazepines or propranolol may be helpful.
Dystonias: Symptoms may include: spasm of the neck muscles, sometimes progressing to torticollis; extensor rigidity of back muscles, sometimes progressing to opisthotonos; carpopedal spasm, trismus, swallowing difficulty, oculogyric crisis and protrusion of the tongue.
These usually subside within a few hours, and almost always within 24 to 48 hours, after the drug has been discontinued.
In mild cases, reassurance or a barbiturate is often sufficient. In moderate cases, barbiturates will usually bring rapid relief. In more severe adult cases, the administration of an anti-parkinsonism agent, except levodopa, usually produces rapid reversal of symptoms. Also, intravenous caffeine with sodium benzoate seems to be effective. In children, reassurance and barbiturates will usually control symptoms. (Or, injectable Benadryl may be useful.) Note: See Benadryl prescribing information for appropriate children's dosage. If appropriate treatment with anti-parkinsonism agents or Benadryl fails to reverse the signs and symptoms, the diagnosis should be reevaluated.
Pseudo-parkinsonism: Symptoms may include: mask-like facies; drooling; tremors; pill-rolling motion; cogwheel rigidity; and shuffling gait. Reassurance and sedation are important. In most cases these symptoms are readily controlled when an anti-parkinsonism agent is administered concomitantly. Anti-parkinsonism agents should be used only when required. Generally, therapy of a few weeks to 2 to 3 months will suffice. After this time patients should be evaluated to determine their need for continued treatment. (Note: Levodopa has not been found effective in pseudo-parkinsonism.) Occasionally it is necessary to lower the dosage of Stelazine (Stelazine) or to discontinue the drug.
Tardive Dyskinesia: As with all antipsychotic agents, tardive dyskinesia may appear in some patients on long-term therapy or may appear after drug therapy has been discontinued. The syndrome can also develop, although much less frequently, after relatively brief treatment periods at low doses. This syndrome appears in all age groups. Although its prevalence appears to be highest among elderly patients, especially elderly women, it is impossible to rely upon prevalence estimates to predict at the inception of antipsychotic treatment which patients are likely to develop the syndrome. The symptoms are persistent and in some patients appear to be irreversible. The syndrome is characterized by rhythmical involuntary movements of the tongue, face, mouth or jaw (e.g., protrusion of tongue, puffing of cheeks, puckering of mouth, chewing movements). Sometimes these may be accompanied by involuntary movements of extremities. In rare instances, these involuntary movements of the extremities are the only manifestations of tardive dyskinesia. A variant of tardive dyskinesia, tardive dystonia, has also been described.
There is no known effective treatment for tardive dyskinesia; anti-parkinsonism agents do not alleviate the symptoms of this syndrome. If clinically feasible, it is suggested that all antipsychotic agents be discontinued if these symptoms appear. Should it be necessary to reinstitute treatment, or increase the dosage of the agent, or switch to a different antipsychotic agent, the syndrome may be masked.
It has been reported that fine vermicular movements of the tongue may be an early sign of the syndrome and if the medication is stopped at that time the syndrome may not develop.
Adverse Reactions Reported with Stelazine (Stelazine) or Other Phenothiazine Derivatives: Adverse effects with different phenothiazines vary in type, frequency, and mechanism of occurrence, i.e., some are dose-related, while others involve individual patient sensitivity. Some adverse effects may be more likely to occur, or occur with greater intensity, in patients with special medical problems, e.g., patients with mitral insufficiency or pheochromocytoma have experienced severe hypotension following recommended doses of certain phenothiazines.
Neuroleptic Malignant Syndrome (NMS) has been reported in association with antipsychotic drugs.
Not all of the following adverse reactions have been observed with every phenothiazine derivative, but they have been reported with one or more and should be borne in mind when drugs of this class are administered: extrapyramidal symptoms (opisthotonos, oculogyric crisis, hyperreflexia, dystonia, akathisia, dyskinesia, parkinsonism) some of which have lasted months and even years-particularly in elderly patients with previous brain damage; grand mal and petit mal convulsions, particularly in patients with EEG abnormalities or history of such disorders; altered cerebrospinal fluid proteins; cerebral edema; intensification and prolongation of the action of central nervous system depressants (opiates, analgesics, antihistamines, barbiturates, alcohol), atropine, heat, organophosphorus insecticides; autonomic reactions (dryness of mouth, nasal congestion, headache, nausea, constipation, obstipation, adynamic ileus, ejaculatory disorders/impotence, priapism, atonic colon, urinary retention, miosis and mydriasis); reactivation of psychotic processes, catatonic-like states; hypotension (sometimes fatal); cardiac arrest; blood dyscrasias (pancytopenia, thrombocytopenic purpura, leukopenia, agranulocytosis, eosinophilia, hemolytic anemia, aplastic anemia); liver damage (jaundice, biliary stasis); endocrine disturbances (hyperglycemia, hypoglycemia, glycosuria, lactation, galactorrhea, gynecomastia, menstrual irregularities, false-positive pregnancy tests); skin disorders (photosensitivity, itching, erythema, urticaria, eczema up to exfoliative dermatitis); other allergic reactions (asthma, laryngeal edema, angioneurotic edema, anaphylactoid reactions); peripheral edema; reversed epinephrine effect; hyperpyrexia; mild fever after large I.M. doses; increased appetite; increased weight; a systemic lupus erythematosus-like syndrome; pigmentary retinopathy; with prolonged administration of substantial doses, skin pigmentation, epithelial keratopathy, and lenticular and corneal deposits.
EKG changes-particularly nonspecific, usually reversible Q and T wave distortions-have been observed in some patients receiving phenothiazine antipsychotics. Although phenothiazines cause neither psychic nor physical dependence, sudden discontinuance in long-term psychiatric patients may cause temporary symptoms, e.g., nausea and vomiting, dizziness, tremulousness.
Note: There have been occasional reports of sudden death in patients receiving phenothiazines. In some cases, the cause appeared to be cardiac arrest or asphyxia due to failure of the cough reflex.
What is the most important information I should know about Stelazine?
Stelazine may cause drowsiness, dizziness, or blurred vision. These effects may be worse if you take it with alcohol or certain medicines. Use Stelazine with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
Do not drink alcohol while you are taking Stelazine.
Check with your doctor before you use medicines that may cause drowsiness (eg, sleep aids, muscle relaxers) while you are taking Stelazine; it may add to their effects. Ask your pharmacist if you have questions about which medicines may cause drowsiness.
Stelazine may cause dizziness, light-headedness, or fainting; alcohol, hot weather, exercise, or fever may increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects.
Do not take more than the recommended dose or use for longer than prescribed without checking with your doctor.
Do not become overheated in hot weather or while you are being active; heatstroke may occur.
NMS is a possibly fatal syndrome that can be caused by Stelazine. Symptoms may include fever; stiff muscles; confusion; abnormal thinking; fast or irregular heartbeat; and sweating. Contact your doctor at once if you have any of these symptoms.
Some patients who take Stelazine may develop muscle movements that they cannot control. This is more likely to happen in elderly patients, especially women. The chance that this will happen or that it will become permanent is greater in those who take Stelazine in higher doses or for a long time. Muscle problems may also occur after short-term treatment with low doses. Tell your doctor at once if you have muscle problems with your arms; legs; or your tongue, face, mouth, or jaw (eg, tongue sticking out, puffing of cheeks, mouth puckering, chewing movements) while taking Stelazine.
Tell your doctor or dentist that you take Stelazine before you receive any medical or dental care, emergency care, or surgery.
Stelazine may lower the ability of your body to fight infection. Avoid contact with people who have colds or infections. Tell your doctor if you notice signs of infection like fever, sore throat, rash, or chills.
Stelazine may reduce the number of clot-forming cells (platelets) in your blood. Avoid activities that may cause bruising or injury. Tell your doctor if you have unusual bruising or bleeding. Tell your doctor if you have dark, tarry, or bloody stools.
Stelazine may increase the amount of a certain hormone (prolactin) in your blood. Symptoms may include enlarged breasts, missed menstrual period, decreased sexual ability, or nipple discharge. Contact your doctor right away if any of these symptoms occur.
Stelazine may cause you to become sunburned more easily. Avoid the sun, sunlamps, or tanning booths until you know how you react to Stelazine. Use a sunscreen or wear protective clothing if you must be outside for more than a short time.
Diabetes patients - Stelazine may affect your blood sugar. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
Stelazine may cause the results of some pregnancy tests to be wrong. Check with your doctor if you have questions or concerns about your pregnancy test results.
Stelazine may interfere with certain lab tests, including phenylketonuria (PKU) tests. Be sure your doctor and lab personnel know you are taking Stelazine.
Lab tests, including liver and kidney function tests, complete blood cell counts, and eye exams, may be performed while you take Stelazine. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
Use Stelazine with caution in the ELDERLY; they may be more sensitive to its effects, especially confusion; constipation; dizziness or light-headedness, especially upon standing; drowsiness; fainting; trouble urinating; and uncontrolled muscle movements.
Stelazine should be used with extreme caution in CHILDREN younger than 6 years old; safety and effectiveness in these children have not been confirmed.
PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of taking Stelazine while you are pregnant. Taking Stelazine during the third trimester may result in uncontrolled muscle movements or withdrawal symptoms in the newborn. Discuss any questions or concerns with your doctor. Stelazine is found in breast milk. Do not breast-feed while taking Stelazine.
If you stop taking Stelazine suddenly, you may have WITHDRAWAL symptoms. These may include dizziness, nausea, tremors, upset stomach, and vomiting.
Contraindication can be described as a special circumstance or a disease or a condition wherein you are not supposed to use the drug or undergo particular treatment as it can harm the patient; at times, it can be dangerous and life threatening as well. When a procedure should not be combined with other procedure or when a medicine cannot be taken with another medicine, it is called Relative contraindication. Contraindications should be taken seriously as they are based on the relative clinical experience of health care providers or from proven research findings.
Stop using this medication and call your doctor at once if you have twitching or uncontrollable movements of your eyes, lips, tongue, face, arms, or legs. These could be early signs of dangerous side effects.
Stelazine is not for use in psychotic conditions related to dementia. Stelazine may cause heart failure, sudden death, or pneumonia in older adults with dementia-related conditions.
Do not use Stelazine if you have liver disease, brain damage, bone marrow depression, a blood cell disorder (such as low platelets or low red or white blood cell counts), or if you are also using large amounts of alcohol or medicines that make you sleepy. Do not use if you are allergic to Stelazine or other phenothiazines.
Before you take Stelazine, tell your doctor about all of your medical conditions, and if you have ever had a serious side effect while using Stelazine or similar medicines. Also, tell your doctor about all other medications you use.
