Ivermectin is a broad spectrum antiparasitic medication derived from fermented soil bacteria. It is primarily used to treat infections caused by nematodes and arthropods in both humans and animals. The drug acts by binding to specific glutamate-gated chloride channels in the nervous system of parasites. This binding increases chloride ion influx leading to hyperpolarization and paralysis of the target organism. In mammals the same channels are not significantly affected due to differences in channel structure and disposition. The resulting paralysis prevents the parasite from feeding and moving which ultimately leads to its death. Pharmacodynamically the compound is metabolized slowly and excreted mainly through the feces over several days.

Ivermectin is an antihelmintic medication used to treat parasitic worm infections. The drug works by binding to glutamate-gated chloride channels in the nervous system of parasites. This binding increases chloride ion influx, leading to paralysis and death of the worms. The selective affinity for parasite channels results in minimal effect on host tissues at therapeutic doses. Ivermectin is absorbed orally and distributed widely, reaching effective concentrations in the gut and tissues where parasites reside. Its long half-life ensures prolonged presence in the body, allowing effective parasite elimination over time. The combination of potent target binding, selective action, and systemic availability underlies its therapeutic effectiveness against parasitic disease.

Some people experience mild stomach upset after taking Ivermectin. Dizziness or light-headedness may occur, especially when standing up quickly. Skin reactions such as itching or rash can appear. Headache is reported in a small number of users. Fatigue or unusual tiredness is occasionally noted. These effects are generally temporary and resolve without specific treatment.

Ivermectin can cause diarrhea in some patients. Patients may experience dizziness as a side effect. Some individuals report nausea after taking the medication. Headaches are a frequently reported adverse reaction. Fatigue can occur during treatment. Skin rashes may develop as a response to the drug. Mild itching can be observed in certain cases. Abdominal discomfort is another possible side effect.
