Side Effects

Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.

Some side effects may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them:

More common

  1. Drowsiness

Less common or rare

  1. Blurred or double vision
  2. constipation
  3. diarrhea
  4. difficult or painful urination
  5. dizziness
  6. dryness of mouth, nose, and throat
  7. fast heartbeat
  8. headache
  9. loss of appetite
  10. nervousness, restlessness, or trouble in sleeping
  11. skin rash
  12. upset stomach

Not all of the side effects listed above have been reported for each of these medicines, but they have been reported for at least one of them. Buclizine, cyclizine, and meclizine are similar, so any of the above side effects may occur with any of these medicines.

Other side effects not listed may also occur in some patients. If you notice any other effects, check with your healthcare professional.

Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.
