Learning About Long-Acting Injectable Antipsychotic Medicines
What are long-acting injectable antipsychotic medicines?
These are medicines that you get as a shot instead of as a pill. Doctors use them to treat certain mental health conditions, such as schizophrenia and bipolar disorder. The medicine releases slowly when it's given as shots. This means the medicine stays in your body longer than if you take a pill.
Why are they given?
A long-acting injection may stabilize your mood and help with disorganized thinking. It can also help with memory or concentration concerns.
You may experience fewer side effects with a shot than with pills. You also won’t need to remember to take a pill each day. Shots may help prevent your symptoms from returning because they keep a steady amount of medicine in the body.
How are they given?
You go to your doctor's office, hospital, or a mental health clinic to get a shot. It's usually given in the arm or the upper hip area. How often you get a shot depends on the type of medicine. You may get it every few weeks, once a month, or every few months.
What are the side effects?
There are possible side effects with these medicines, whether they are given as a shot or as a pill. They include:
- Movement disorders. These are body movements that are hard to control.
- Some may happen soon after you get the shot. They include muscle spasms and trouble sitting still.
- Neuroleptic malignant syndrome. This is a rare but life-threatening condition. The first signs include a high fever and changes in heart and breathing patterns. If you have these symptoms, see your doctor right away.
- Drowsiness.
- Weight gain.
- Increase in cholesterol or blood sugar levels.
- Type 2 diabetes.
- Heart problems.
- Irregular menstrual cycles.
- Problems having sex.
You may have pain or redness where you get the shot. You also may have other side effects not listed here. Talk to your doctor about the possible side effects from your medicine.
You may be asked to wait for a while in the doctor's office, hospital, or mental health clinic after you get the shot. This is to watch for possible problems with the shot.
