Side effects of Metoclon in details

Neurological: Adverse reactions to Metoclon that are most frequently seen are restlessness, drowsiness, fatigue and lassitude, which occur in approximately 10% of patients. Insomnia, headache, dizziness have been reported less frequently. Acute depression has been reported rarely (<1 in 1000 cases). Symptoms of Metoclon induced depression have ranged from mild to severe and have included suicidal ideation and suicide. Anxiety or agitation may occur, especially after rapid injection. Delirium, severe dysphoria, obsessive rumination and mania have been reported occasionally.

Parkinsonian symptoms including tremor, rigidity, bradykinesia and akinesia, occur rarely in patients receiving Metoclon but may be associated with usual or excessive doses or with decreased renal function.

Various extrapyramidal reactions to Metoclon, usually of the dystonic type, have been reported. Acute dystonic reactions occur in approximately 0.2% of patients treated with Metoclon 30-40 mg/day. In cancer chemotherapy, patients receiving 1-2 mg/kg/dose, the incidence is 2% in patients over the ages of 30-35, and 25% or higher in children and young adults who have not had prophylactic administration of diphenhydramine. Reactions include spasm of the facial muscles, trismus, rhythmic protrusion of the tongue, a bulbar type of speech, spasm of the extraocular muscles including oculogyric crisis, unnatural positioning of the head and shoulders and opisthotonos. There may be a generalised increase in muscle tone. The majority of reactions occur within 36 hrs of starting treatment and the effects usually disappear within 24 hrs of withdrawal of the drug. However, close observation is required, and in cases of more severe reactions, an antiparkinson drug eg, benztropine or an anticholinergic antihistamine eg, diphenhydramine should be given.

A fatal acute dystonic reaction has been reported in a patient who received hexamethylmelamine, cisplatin and Metoclon high dose. Dystonic reactions may present rarely as upper airway obstruction with stridor and dyspnoea, possibly secondary to laryngospasm or supraglottic dystonia. A fatal cardiorespiratory arrest occurred in at least 1 patient with an acute dystonic reaction.

Tardive dyskinesia, which may be persistent, has been reported particularly in elderly patients (particularly women) following long-term therapy with Metoclon. Tardive dyskinesia is most frequently characterised by involuntary movements of the tongue, face, mouth or jaw, and sometimes by involuntary movements of the trunk and/or extremities. The risk of developing tardive dyskinesia and the likelihood that it will become irreversible are believed to increase with increasing duration of therapy and total cumulative dose. Although tardive dyskinesia can occur after relatively brief therapy with the drug at low doses, it appears to be more readily reversible under such circumstances.

Neuroleptic Malignant Syndrome (NMS): It has been reported very rarely (<2 in 10,000). NMS is potentially fatal and comprises hyperpyrexia, altered consciousness, muscle rigidity, autonomic instability and elevated levels of CPK, and must be treated urgently (recognised treatments include dantrolene and bromocriptine).

Metoclon should be stopped immediately if NMS occurs.

Gastrointestinal: Nausea or bowel disturbances have been reported.

Cardiovascular: A single case of supraventricular tachycardia following IM administration has been reported. Cardiac conduction abnormalities (eg, bradycardia and heart block) have occurred very rarely (<1 in 10,000) in association with IV Metoclon. Atrial fibrillation, oedema, ventricular fibrillation, ventricular tachycardia, palpitations and tachycardia have also been associated with the use of Metoclon. In 1 study in hypertensive patients, IV administered Metoclon was shown to release catecholamines; hence, caution should be exercised when Metoclon is used in patients with hypertension.

Endocrine: Raised serum prolactin levels have been observed during Metoclon therapy; this effect is similar to that noted with many other compounds. Galactorrhoea and breast enlargement have also been observed during Metoclon therapy.

Hypersensitivity: There have been isolated reports of hypersensitivity reactions (eg, urticaria, maculopapular rash) in patients receiving the drug.

Respiratory: Respiratory failure, secondary to dystonic reaction, acute asthmatic symptoms of wheezing and dyspnoea may occur.

Genitourinary: Urinary incontinence, sexual dysfunction, priapism and muscle spasm may also occur.

Other Effects: There have been isolated reports of blood disorders. Methaemoglobinaemia, particularly following overdose in neonates, has also occurred in patients receiving the drug. Agranulocytosis and hyperthermia have also been observed.

What is the most important information I should know about Metoclon?

• Metoclon syrup may cause drowsiness, dizziness, or blurred vision. These effects may be worse if you take it with alcohol or certain medicines. Use Metoclon syrup with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
• Do not drink alcohol or use medicines that may cause drowsiness (eg, sleep aids, muscle relaxers) while you are using Metoclon syrup without first checking with your doctor; it may add to their effects. Ask your pharmacist if you have questions about which medicines may cause drowsiness.
• Diabetes patients- Metoclon syrup may affect your blood sugar. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
• Neuroleptic malignant syndrome (NMS) is a possibly fatal syndrome that can be caused by Metoclon syrup. 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 Metoclon syrup 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 Metoclon syrup 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 Metoclon syrup.
• Lab tests, including liver and kidney function tests, may be performed while you use Metoclon syrup. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
• Metoclon syrup should not be used in CHILDREN younger than 15 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 using Metoclon syrup while you are pregnant. Metoclon syrup is found in breast milk. If you are or will be breast-feeding while you use Metoclon syrup, check with your doctor. Discuss any possible risks to your baby.

Metoclon contraindications

NEVER TAKE Metoclon IN LARGER AMOUNTS THAN RECOMMENDED, OR FOR LONGER THAN 12 WEEKS. High doses or long-term use of Metoclon can cause a serious movement disorder that may not be reversible. Symptoms of this disorder include uncontrollable muscle movements of your lips, tongue, eyes, face, arms, or legs. The longer you take Metoclon, the more likely you are to develop a serious movement disorder. The risk of this side effect is higher in women, diabetics, and older adults.

You should not take this medication if you are allergic to Metoclon, or if you have bleeding or blockage in your stomach or intestines, epilepsy or other seizure disorder, or an adrenal gland tumor (pheochromocytoma).

Before you take Metoclon, tell your doctor if you have kidney or liver disease, congestive heart failure, high blood pressure, diabetes, Parkinson's disease, or a history of depression.

Do not drink alcohol. It can increase some of the side effects of Metoclon.

There are many other medicines that can interact with Metoclon. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor. Keep a list of all your medicines and show it to any healthcare provider who treats you.

Stop using Metoclon and call your doctor at once if you have tremors or uncontrolled muscle movements, fever, stiff muscles, confusion, sweating, fast or uneven heartbeats, rapid breathing, depressed mood, thoughts of suicide or hurting yourself, hallucinations, anxiety, agitation, seizure, or jaundice (yellowing of your skin or eyes).
