Selamectin is a broad-spectrum topical parasiticide for use in dogs and cats. It is effective in preventing and treating common parasites, including fleas, ear mites, heartworm disease, sarcoptic mange, and certain types of intestinal worms in cats. This medication kills parasites by targeting their nervous system and is applied directly to the skin, typically at the base of the neck, once a month.
Selamectin is generally considered safe for dogs aged 6 weeks and older and cats aged 8 weeks and older, with dosing based on the animal’s weight. This solution is generally well-tolerated, though mild side effects such as drooling, vomiting, or skin irritation may occur. When you order Selamectin online, always adhere to the prescribed dosage to ensure the best protection against parasites and overall pet health.

Note: For pets weighing more than the listed ranges, veterinarians may recommend combining doses or using multiple tubes to achieve the appropriate strength. Always follow your vet’s guidance and use species-specific products. Never split or mix doses without professional advice.
How to apply Selamectin safely on your dogs and cats:
Selamectin spot-on solution works by absorbing through your pet’s skin into the bloodstream, where it targets the nervous system of parasites. It causes paralysis and death in fleas, ticks, mites, and certain intestinal worms, and prevents heartworm disease by killing immature heartworm larvae.
Note: Contact your veterinarian or an emergency animal clinic immediately if your pet experiences any serious symptoms or unusual changes after using Selamectin.
Before using Selamectin on your dog or cat, carefully read the following warnings:
Consider these safety precautions when you start your pet's treatment with Selamectin topical solution:
If you miss a scheduled application of Selamectin on your dog or cat, apply it as soon as you remember. Do not double-dose at the next scheduled time. Instead, resume the regular monthly dosing schedule to maintain continuous protection against fleas, ticks, heartworm, and other parasites.
An overdose is rare if Selamectin is used as directed on dogs and cats. However, if too much is applied or the medication is accidentally ingested, it may cause mild side effects such as vomiting, drooling, diarrhea, or lethargy. In rare cases, neurological symptoms like tremors may occur. Contact your nearest veterinarian or an emergency animal clinic right away if an overdose is suspected.
