General information about side effects

All medicines can cause side effects. Many people don't have side effects. And minor side effects sometimes go away after a while.

But sometimes side effects can be a problem or can be serious.

If you're having problems with side effects, talk to your doctor. He or she may be able to lower your dose or change to a different medicine.

Always be sure you get specific information on the medicine you're taking. For a full list of side effects, check the information that came with the medicine you're using. If you have questions, talk to your pharmacist or doctor.

Cautions about antipsychotics

Cautions for antipsychotics include the following:

  • Antipsychotics may cause you to do a movement over and over, like smacking the lips. This is known as tardive dyskinesia. Talk to your doctor if you have symptoms.
  • These medicines may cause a fast or uneven heartbeat, fast breathing, and severe sweating. Talk to your doctor if you have symptoms.
  • These medicines have been well studied for use in adults. But there are no long-term studies that show how well they work and how safe they are for children and teens.

Cautions for all medicines

  • Allergic reactions: All medicines can cause a reaction. This can sometimes be an emergency. Before you take any new medicine, tell the doctor or pharmacist about any past allergic reactions you've had.
  • Drug interactions: Sometimes one medicine may keep another medicine from working well. Or you may get a side effect you didn't expect. Medicines may also interact with certain foods or drinks, like grapefruit juice and alcohol. Some interactions can be dangerous.
  • Harm to unborn babies and newborns: If you are pregnant, trying to get pregnant, or breastfeeding, ask your doctor or pharmacist if any of the medicines you take could harm your baby.
  • Other health problems: Before taking a medicine, be sure your doctor or pharmacist knows about all your health problems. Other health problems may affect your medicine. Or the medicine for one health problem may affect another health problem.

Always tell your doctor or pharmacist about all the medicines you take. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. That information will help prevent serious problems.

Always be sure you get specific information on the medicine you're taking. For a full list of warnings, check the information that came with the medicine you're using. If you have questions, talk to your pharmacist or doctor.
