Stromectol (Ivermectin)
Stromectol (Ivermectin) Dosage and Side Effects
Doctors prescribe STROMECTOL to treat parasites in the intestines, river blindness, scabies, and lice on the head and in the pubic area. STROMECTOL belongs to group of drugs known as antiparasitics. It works by increasing the amount of chloride that flows into the parasite's nervous system, which ultimately paralyzes and kills the parasite.
Warnings and Precautions
You shouldn’t take STROMECTOL if you’re allergic to STROMECTOL or any ingredients in the drug.
Talk to your doctor before taking STROMECTOL if you have asthma or a skin condition called onychodermatitis.
Pregnancy and STROMECTOL
STROMECTOL has not been well studied in pregnant humans.
Before taking STROMECTOL, talk to your doctor about whether the drug benefits outweigh the potential risks to your unborn baby.
Whether or not STROMECTOL is for mothers who are breastfeeding has not been determined.
Tell your doctor if you’re pregnant, planning a pregnancy, or breastfeeding before taking STROMECTOL.
STROMECTOL for Dogs and Cats
Veterinarians often prescribe STROMECTOL (under the brand names Heartgard, Ivomec, Iverhart, and others) for dogs and cats.
The drug is used to treat parasitic infections such as heartworm, mange, and ear mites.
Low doses of STROMECTOL are generally considered safe for animals.
However, STROMECTOL is not suitable for all dogs. Some carry a mutated gene (MDR-1) that makes the dog especially sensitive to STROMECTOL toxicity.
In dogs with this mutation, STROMECTOL can pass into the brain and nervous system with deadly consequences.
There are some dog breeds that are more sensitive to STROMECTOL than others. These include Australian and German Shepherds; English, Old English, and Shelton Sheepdogs; Syke Terriers; and Collies.
However, your dog's breed is not necessarily a guarantee that there will or will not be a problem with STROMECTOL.

This includes prescriptions and over-the-counter medications, vitamins and other dietary supplements (nutritional shakes, protein powders, etc.), herbal remedies, and illegal and recreational drugs.
Ask your doctor about taking Stromectol with warfarin (Coumadin, Jantoven), since Stromectol may increase the side effects of the blood thinner.
STROMECTOL and Alcohol
You should avoid or limit drinking alcohol while taking STROMECTOL, because the combination may increase your risk of serious side effects of the drug.
STROMECTOL and Grapefruit Juice
Grapefruit juice slows down how quickly the body is able to break down STROMECTOL, which could cause blood levels of the drug to become dangerously high.
Do not consume grapefruit or grapefruit juice while you’re taking STROMECTOL.
