All About Heartworm Prevention Medicine

Heartworm disease is a serious and potentially fatal condition that affects dogs and cats. It is caused by a parasitic worm known as Dirofilaria immitis, which is transmitted by mosquitoes. April is Heartworm Awareness Month, a time to raise awareness about this preventable disease and the importance of heartworm prevention medicine.

Understanding Heartworm Disease: Causes, Symptoms, and Risks

Heartworm disease is particularly prevalent in warm, humid areas, but it can occur anywhere that mosquitoes are present. The parasite is transmitted to dogs and cats through the bite of an infected mosquito. Once inside the animal’s body, the worms can grow up to a foot long and can cause damage to the heart, lungs, and blood vessels. In severe cases, heartworm disease can be fatal.

Types of Heartworm Prevention Medication

Fortunately, heartworm disease is easily preventable with the use of heartworm prevention medicine. There are several different types of heartworm prevention medication available, including monthly tablets, topical treatments, and injections. These medications work by killing the larvae of the heartworm parasite before they have a chance to develop into adults.

TABLET – The most common type of heartworm prevention medication is a monthly tablet, which is typically administered orally to dogs and cats. These tablets contain an active ingredient that kills the heartworm larvae and prevents them from developing into adults. Monthly tablets are easy to administer and are generally well-tolerated by pets.

TOPICAL – Topical treatments are another option for heartworm prevention. These treatments are applied to the skin of the pet and are absorbed into the bloodstream, where they kill the heartworm larvae. Topical treatments are convenient to use and are especially useful for pets that have difficulty taking oral medications.

INJECTION – Injections are a less common form of heartworm prevention medication. These injections are typically administered by a veterinarian and provide long-lasting protection against heartworm disease. Injections are generally reserved for pets that are at high risk of heartworm disease or for pets that have difficulty taking oral medications.


It is important to note that heartworm prevention medication should be administered year-round, even in areas with cold winters. Mosquitoes can survive indoors during the winter months, so pets are still at risk for heartworm disease even when it’s cold outside.
