Composition and appearance Active ingredient: The generic constituent of the cream is Ivermectin, which acts against a broad spectrum of parasites and worms.

Binding to Glutamate Gated Chloride Ion Channels: The chemical acts specifically and binds with high affinity to the receptors for chloride ions present in invertebrate nerves and muscles. Hyperpolarization: Due to the high affinity and specificity of action, the cell membrane becomes highly permeable to the negatively charged ions. The flow of negatively charged ions hyperpolarizes the nerve and muscle cells. Paralysis: After paralysing the nerves, the parasite stops breathing, moving around, and feeding. Thus, it eventually dies. Dosage and administration Dosage: This Lotion is suitable to both adults and children but in a suitable dosage. For adults: Use a pea-sized amount of the cream 1 time daily for minor issues and up to 3 times daily for severe issues. For children: The suitable dose is given by the doctors after checking the age and weight of the child. However, it is not suitable to children below 2 years.
