Clemastine is a prescription antihistamine medication commonly used in the treatment and prevention  of allergies. Antihistamines work by blocking histamine, a substance produced during an allergic reaction or sensitivity. If your pet has been diagnosed with allergies or suffers from allergy like symptoms, your veterinarian may prescribe an antihistamine such as clemastine. This medication helps relieve the symptoms associated with allergies, and is not a treatment to eliminate them. Talk with your pet’s veterinarian before administering this medication and follow their specific recommendations for use.

  • Read and follow the prescription label carefully for storage information, possible side effects, and drug interactions.
  • Give the exact amount prescribed and only as often as directed.
  • Do not skip doses or stop giving the medication without consulting your veterinarian.
Clesmastine is sold as an FDA approved generic drug. Brand varies from order to order and variation to variation. VetRxDirect is unable to guarantee which brand will be available at the time of order shipment.
