• Nausea, vomiting, constipation, dry mouth, or increased saliva.
• Weight gain or loss.
• Skin rash, pinkish, itchy swellings on the skin (hives).

Serious side effects, though rare, require immediate medical attention:

• Tardive dyskinesia (uncontrolled movements of the tongue, mouth, cheeks, or jaw, which may progress to arms and legs).
• Neuroleptic Malignant Syndrome (NMS), characterized by high fever, severe muscle stiffness, confusion, and fluctuating blood pressure.
• Heart problems such as irregular heartbeat, abnormally fast heartbeat, or QT prolongation.
• Shortness of breath, wheezing, or difficulty breathing.
• Swelling of the face, lips, mouth, tongue, or throat.
• Convulsions, fits, or seizures.

Precautions

• Allergies: Do not take SERENACE if you are allergic to haloperidol or any of its ingredients.
• Medical Conditions: Inform your doctor if you have Parkinson's disease, severe depression, brain damage, severe drowsiness, coma, heart conditions (e.g., prolonged QT interval, heart failure), thyroid problems, epilepsy, glaucoma, or liver/kidney disease.
• Pregnancy and Breastfeeding: SERENACE is not generally recommended during pregnancy or breastfeeding as it may pass into breast milk and affect the baby.
• Alcohol: Avoid alcohol consumption as it can increase drowsiness, dizziness, and light-headedness.
• Driving and Machinery: SERENACE may cause dizziness, drowsiness, or blurred vision. Do not drive or operate machinery until you know how the medicine affects you.
• Sun Exposure: Be careful in hot environments and wear protective clothing with at least SPF 15+ sunscreen when outdoors, as SERENACE may cause reduced sweating and overheating.
• Drug Interactions: Inform your doctor about all other medicines you are taking, including over-the-counter drugs, herbal supplements, and vitamins, as some can interact with SERENACE (e.g., blood thinners, anticholinergics, antihistamines, certain heart medications, antidepressants, antibiotics).
• Smoking: Nicotine can affect the amount of haloperidol in your body, so sudden changes in smoking habits should be discussed with your doctor.

Storage

Keep SERENACE tablets in their original bottle or pack until it is time to take them. Store them in a cool, dry place where the temperature stays below 30°C, away from moisture, heat, or direct sunlight. Do not store in the bathroom, near a sink, in the car, or on windowsills. Keep out of reach of children and pets.

SERENACE 0.5 (Haloperidol) is an antipsychotic medication primarily used to treat various mental, emotional, and behavioral conditions. Manufactured by RPG Life Sciences Limited, it contains Haloperidol as its active ingredient.

Here are some frequently asked questions about SERENACE 0.5:

What is SERENACE 0.5 used for?

SERENACE 0.5 is used to manage symptoms of several conditions, including schizophrenia, acute psychosis, Tourette's syndrome (for tics and verbal outbursts), mania in bipolar disorder, acute delirium, and severe behavioral problems like agitation, aggressiveness, and hyperactivity in adults and children (aged 6-17 for behavioral problems, 13-17 for schizophrenia). It can also be used for conditions such as hiccups, chorea, and nausea and vomiting. It is not approved for use in older adults with dementia-related psychosis due to an increased risk of death.

How does SERENACE 0.5 work?

SERENACE 0.5 contains Haloperidol, a first-generation (typical) antipsychotic. It works by blocking dopamine D2 receptors in the brain, particularly in areas associated with thoughts and mood, known as the mesolimbic and mesocortical systems. This action helps to reduce psychotic symptoms such as hallucinations and delusions by decreasing dopamine activity. It also has some effects on serotonin 5-HT2 and alpha-1 receptors.

What is the usual dosage for SERENACE 0.5?

The dosage of SERENACE 0.5 varies depending on the patient's age and condition. For adults and children aged 13 and older, the initial oral dose typically ranges from 0.5 to 5 milligrams (mg) two or three times a day, though the maximum recommended daily oral dose is 30 mg, used only in exceptional circumstances, as doses above 10 mg/day are unlikely to provide additional efficacy. Older adults might start with a lower dose, such as 0.5 to 2 mg two or three times daily. For children aged 3 to 12 with severe behavioral problems, the dose is typically weight-based and determined by a doctor, often starting at 0.5 mg per day and gradually increasing. It's crucial to follow your doctor's specific instructions, as it may take several days to weeks for the full effect to be reached.

What are the possible side effects of SERENACE 0.5?

Common side effects can include dry mouth, blurred vision, constipation, nausea, vomiting, dizziness, headache, weight gain, and difficulty sleeping. SERENACE 0.5 can also cause movement-related side effects, known as extrapyramidal symptoms, which may include tremors, muscle stiffness, restlessness (akathisia), or involuntary movements (dystonia, tardive dyskinesia).

More serious but less common side effects include Neuroleptic Malignant Syndrome (NMS), characterized by high fever, severe muscle stiffness, and confusion, and QT prolongation, which is an irregular heartbeat that can be life-threatening.

Is SERENACE 0.5 safe during pregnancy or breastfeeding?

During pregnancy: There are no adequate and well-controlled studies of Haloperidol in pregnant women. Some reports have linked its use to limb reduction defects, though a causal relationship is unclear due to multi-drug exposures. If used in the weeks before birth, it may cause temporary withdrawal symptoms or extrapyramidal symptoms in newborns. SERENACE 0.5 should only be used during pregnancy if the potential benefit justifies the possible risk to the fetus, and this should be discussed with a doctor.

During breastfeeding: Haloperidol passes into breast milk. It may cause side effects in breastfed infants such as drowsiness, difficulty feeding, or slow movements. Due to these potential risks, breastfeeding is generally not recommended, or caution is advised, and the infant should be monitored for any adverse effects.

Can SERENACE 0.5 be taken with other medications?

SERENACE 0.5 can interact with many medications. It should be used with caution, or avoided, with:

• Alcohol and other CNS depressants: These can increase drowsiness and other side effects.
• QT-prolonging drugs: Medications like amiodarone, pimozide, quinidine, sotalol, and certain antibiotics or antidepressants can increase the risk of an irregular heartbeat when taken with Haloperidol.
• Lithium: Concomitant use can lead to a serious neurological condition called encephalopathic syndrome.
• Parkinson's medications (e.g., levodopa): Haloperidol can block their effects and worsen Parkinson's symptoms.
• Certain blood pressure medications (e.g., guanethidine, methyldopa): Haloperidol may reduce their effectiveness or increase side effects.
• Drugs affecting liver enzymes (CYP3A4/CYP2D6 inhibitors/inducers): Some medications like ketoconazole, fluoxetine, carbamazepine, or rifampin can alter the levels of Haloperidol in the body. Always inform your doctor or pharmacist about all medications, supplements, and herbal products you are taking.

What precautions should be taken while using SERENACE 0.5?

It is important to not stop taking SERENACE 0.5 abruptly, as this can lead to withdrawal symptoms or a worsening of your condition; your doctor will advise on a gradual reduction if needed. Regular follow-up appointments with your doctor are essential, especially during the initial months of treatment. Avoid alcohol consumption. Exercise caution when driving or operating machinery, as the medicine can cause dizziness or drowsiness. You may be more sensitive to sunlight, so take protective measures. SERENACE 0.5 can also affect your body's ability to regulate temperature, so avoid overheating. Inform your doctor about any pre-existing medical conditions, especially heart problems, seizures, Parkinson's disease, dementia, low white blood cell counts, or thyroid disease.

What happens if a dose of SERENACE 0.5 is missed?

If you miss a dose of SERENACE 0.5, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one, as this can lead to dangerous side effects.

How should SERENACE 0.5 be stored?

SERENACE 0.5 should be stored in a closed container at room temperature, away from excessive heat, moisture, and direct light. It should also be kept from freezing. Keep all medications out of the reach of children and pets.
