Sperid 1 is a prescription medicine used in the treatment of schizophrenia (a mental disorder that can result in hallucinations or delusions and also adversely affects a person’s ability to think and behave) and mania. Sperid 1 is taken with or without food, preferably at night. However, it is advised to take it at the same time each day as this helps to maintain a consistent level of medicine in the body. Take this in the dose and duration as advised by your doctor and if you have missed a dose, take it as soon as you remember. It is important that this medication is not stopped suddenly without talking to your doctor as it may worsen your symptoms. However, discontinue this medicine immediately if you experience Neuroleptic malignant syndrome (NMS), characterized by fever, muscle rigidity, and altered consciousness or seizures. Some common side effects of this medicine include dryness in mouth, constipation, muscle rigidity, restlessness, and tremor. Initially, this medicine may cause a sudden drop in blood pressure when you change positions, so it is better to rise slowly if you have been sitting or lying down. It also causes dizziness and sleepiness, so do not drive or do anything that requires mental focus until you know how this medicine affects you. This medicine may increase your weight but, modifying your lifestyle by having a healthy diet and exercising regularly can reduce this side effect. You should be cautious while using this medicine as it may increase the risk of developing diabetes, so it is better to monitor glucose regularly. Inform your doctor if you develop any unusual changes in mood or behavior, new or worsening depression, or suicidal thoughts while taking this medicine.

Contraindication
Risperidone is contraindicated in patients with a known hypersensitivity to the product.
Mode of Action
Risperidone is an atypical antipsychotic. Its activity is mediated through a combination of dopamine (D2) and serotonin (5-HT2) receptor antagonism. It also exhibits affinity to adrenergic (alpha1 and alpha2) and histamine (H1) receptors. It is less likely to cause extrapyramidal effects than conventional antipsychotics.
Precaution
Preexisting CV diseases; discontinue use if signs and symptoms of tardive dyskinesia occur; renal and hepatic impairment, elderly, epilepsy; parkinsonism; pregnancy. May cause drowsiness and orthostatic hypotension. Gradual withdrawal is recommended. Monitor blood glucose in diabetics and patients at risk of developing diabetes.
