How To Use
- Use Risperdal Consta exactly as prescribed.
- Risperdal Consta is given by intramuscular injection (IM) into the buttock by a healthcare professional once every two weeks.
- Injections should alternate between the two buttocks.
- Once the medication has been prepared, shake well before injecting.
- Do not give by injection into a vein (intravenously or IV).
- Injected risperidone may take up to three weeks to begin working.
- During this time, you should still take the oral form of Risperdal Consta or another medication for your condition by mouth.
- After three weeks, your doctor should have you stop taking the oral form, but follow the directions provided.
- The dosage is based on your medical condition and response to therapy.
- Continue to take Risperdal Consta as directed, even if you are feeling better and thinking more clearly.
Side Effects
- Dizziness, drowsiness, fatigue, dry mouth, indigestion, constipation, runny nose, weight gain or loss, acne, dry skin, or redness/swelling/pain at the injection site 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.
- Tell your doctor immediately if any of these serious side effects occur: fainting, rapid/pounding/irregular heartbeat, mental/mood changes, tremor, fever, muscle stiffness/spasms/twitching, sweating, uncontrolled muscle movements (e.g., tongue and facial muscles), drooling, difficulty swallowing, seizures.
- Tell your doctor immediately if any of these unlikely but serious side effects occur: chest pain, one-sided weakness, numbness in the face/arms/legs, sudden vision changes, slurred speech, confusion.
- Males: In the unlikely event you have a painful, prolonged erection, stop using Risperdal Consta and seek immediate medical attention or permanent problems could occur.
- Risperdal Consta 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.
- Risperdal Consta may infrequently make your blood sugar level rise, therefore causing or worsening diabetes.
- This high blood sugar can rarely cause serious (sometimes fatal) conditions such as diabetic coma.
- Tell your doctor immediately if you develop symptoms of high blood sugar, such as increased thirst and urination, or vision changes.
- If you already have diabetes, be sure to check your blood sugar level regularly.
- A serious allergic reaction to Risperdal Consta is unlikely, but seek immediate medical attention if it occurs.
- Symptoms of a serious allergic reaction include: rash, itching, swelling, severe dizziness, trouble breathing.

- Risperdal Consta can reduce sweating.
- Heatstroke may occur if you become overheated during exercise or other physical activity or in hot weather.
- Drink plenty of liquids to avoid the risk of heatstroke.
