Amlodipine besylate, or Norvasc as it's commonly known, may be familiar to you because it's prescribed commonly for people with high blood pressure. However, it's also useful for dogs and cats suffering from hypertension. If the vet prescribed Norvasc for Dexter, be sure to give him his medicine as directed.
Amlodipine Besylate: the Calcium Blocker
Whether it's you or your pup, you both need calcium for your muscles to function properly. When a muscle is stimulated, calcium is released, causing the muscle to contract. If Dexter has high blood pressure, his heart must work harder to do its job. Amlodipine besylate helps the process by blocking the calcium necessary to contract the muscles, forcing the blood vessels to relax, ultimately lowering Dexter's blood pressure. There are potential side effects from amlodipine besylate, including low blood pressure, lethargy, decreased appetite, weight loss, quicker heart rate and swollen gums. The drug can interact with other medication, so be sure your vet has a complete list of your pup's medications, as well as a thorough medical history. Pregnant or nursing dogs shouldn't take Norvasc, and a dog with liver disease should be monitore closely. Make sure Dexter takes his medicine as directed; missing a dose can result in increased blood pressure. PetMD notes that if a dose is missed, you should give the dose as soon as possible. However, you should not give your dog two doses at once; if it's almost time for the next scheduled dose, skip the missed dose and resume your regular schedule.
