Risperidone Oral Side Effects

Dizziness, drowsiness, fatigue, nausea, constipation, runny nose, increased appetite, weight gain, nervousness, acne, dry skin, difficulty concentrating, decreased sexual ability/desire or difficulty sleeping may occur. If any of these effects persist or worsen, contact your doctor or pharmacist promptly.

To minimize dizziness and lightheadedness, get up slowly when rising from a seated or lying position.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor immediately if any of these serious side effects occur:

severe dizziness
fainting
fast/pounding/irregular heartbeat
mental/mood changes

muscle stiffness/spasms/twitching

This medication may in rare instances increase your blood level of a certain hormone (prolactin). In females, an increase in prolactin levels may result in unwanted breast milk, the end of menstruation or difficulty becoming pregnant. In males, it may result in decreased sexual ability, inability to produce sperm, or enlarged breasts. If you develop any of these symptoms, tell your doctor immediately.
