What Is Ivermectin 12mg?
Ivermectin is a prescription medication commonly used to treat parasitic infections in humans. It belongs to a class of medicines known as antiparasitic agents. The 12mg tablet strength is one of the most commonly prescribed dosages for adults.
The medicine works by paralyzing and killing certain parasites in the body. Doctors may recommend it for conditions such as:

According to the World Health Organization (WHO), ivermectin has played an important role in controlling several neglected tropical diseases worldwide.
How Does Ivermectin 12mg Work?
When a person takes Ivermectin 12mg for humans, the medicine targets the nervous system of parasites. It interferes with nerve and muscle functions in parasites, eventually causing paralysis and death of the organisms.
Unlike antibiotics that fight bacteria, ivermectin specifically targets parasites. This is why it is mainly prescribed for parasitic infections and not for general viral or bacterial illnesses.
The medication is usually absorbed quickly into the bloodstream and begins working within hours after consumption. However, the complete effect may take several days depending on the infection being treated.
