Tell the doctor in charge that you are taking ANTIVERT before you have any skin tests for allergies. The results of the test may be affected by ANTIVERT.

Buclizine, cyclizine, or meclizine will add to the effects of alcohol and other CNS depressants (medicines that make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies, or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or narcotics; barbiturates; medicine for seizures; muscle relaxants; or anesthetics, including some dental anesthetics. Check with your doctor before taking any of the above while you are using ANTIVERT.

ANTIVERT may cause some people to become drowsy or less alert than they are normally. Make sure you know how you react to ANTIVERT before you drive, use machines, or do anything else that could be dangerous if you are not alert.

Buclizine, cyclizine, and meclizine may cause dryness of the mouth. For temporary relief use sugarless candy or gum, melt bits of ice in your mouth, or use a saliva substitute. However, if your mouth continues to feel dry for more than 2 weeks, check with your medical doctor or dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.

Along with its needed effects, a medicine may cause some unwanted effects. The following side effects may go away during treatment as your body adjusts to the medicine; however, check with your doctor if they continue or are bothersome:

• More common
  • Drowsiness 
  
  

• Less common or rare
  • Blurred or double vision;  constipation;  diarrhea;  difficult or painful urination;  dizziness;  dryness of mouth, nose, and throat;  fast heartbeat;  headache;  loss of appetite;  nervousness, restlessness, or trouble in sleeping;  skin rash;  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 above may also occur in some patients. If you notice any other effects, check with your doctor.

Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, some of these medicines are used in certain patients to prevent the following medical conditions:

• Nausea and vomiting following surgery
• Nausea and vomiting following cancer radiation treatment

Other than the above information, there is no additional information relating to proper use, precautions, or side effects for these uses.
