Take the medication exactly as prescribed with or without food. Initially the doctor may give you a small dose and increase it slowly as your body gets used to the medication.

The medication should not be stopped without the doctor's approval and it should be used regularly and at the same time each day for best results. If your condition remains static or deteriorates inform the doctor.

How risperidone works

The exact procedure that risperidone uses in order to be effective is not fully understood. However, just like other antipsychotics, it interferes with the communication between the nerves in the brain. Nerves communicate with each other when they make and release certain chemicals known as neurotransmitters. Neurotransmitters attach themselves to nerve receptors when they travel to nearby nerves. This attachment will either inhibit or activate the function of these nerves.

Risperidone blocks the nerve receptors like dopamine type 2, serotonin type 2, and also the alpha 2 adrenergic receptors. Psychotic disorders are caused when communication between nerves in the brain becomes abnormal and alters the way neurotransmitters communicate. Risperidone works by altering this psychotic state.

Possible interactions

Herbal medications like St. John's wort could worsen sensitivity to the sun and could also increase serotonin when used with risperidone and so combining the two is not advisable. Ma huang and yohimbe are two other herbal remedies that should be avoided. Kava kava and valerian could increase drowsiness. Ginseng that works partly as an MAO inhibitor should not be combined with risperidone. Alcohol should not be imbibed while taking risperidone and smoking marijuana is not advisable either as sleepiness and inactivity could increase. Avoid exposure to the sun as the medication could lead to an increase in photosensitivity.


Do not stop taking risperidone without first consulting the doctor.
