What are Ivermectin 12 mg Tablets?

Ivermectin belongs to a group of medicines known as antiparasitic agents. It works by killing or disabling certain parasites that infect the human body. Unlike antibiotics, ivermectin is not used to treat bacterial infections, and it is not intended for viral illnesses.

Ivermectin 12 mg tablets are commonly prescribed to treat specific parasitic infections, including:

• Strongyloidiasis (intestinal roundworm infection)
• Onchocerciasis (river blindness)
• Certain cases of scabies, when recommended by a healthcare professional
• Other parasitic infections, depending on the medical assessment

The medicine is available only through licensed healthcare providers or regulated pharmacies in many countries.

How Does Ivermectin Work?

Parasites rely on nerve and muscle signals to survive inside the body. Ivermectin interferes with these signals by binding to specific chloride channels found in susceptible parasites.

This process:

• Paralyzes the parasites
• Prevents them from surviving
• Allows the body’s immune system to remove the infection

Because human nerve cells function differently, ivermectin has an established safety profile when prescribed at appropriate doses for approved indications.

Approved Medical Uses

Healthcare professionals may prescribe Ivermectin 12 mg tablets for several parasitic diseases.

Strongyloidiasis

Strongyloidiasis is caused by Strongyloides stercoralis. Without treatment, the infection may persist for years and can become serious in people with weakened immune systems.

Onchocerciasis (River Blindness)

This parasitic disease is transmitted through blackfly bites and can affect the skin and eyes. Ivermectin helps reduce the number of parasites responsible for the disease.

Certain Scabies Cases

Oral ivermectin may be prescribed for severe, crusted, or treatment-resistant scabies when appropriate. Your healthcare provider will determine whether it is suitable for your situation.

Other Parasitic Infections

Depending on local clinical guidance, ivermectin may be used for selected parasitic infections after careful evaluation.

Conditions Ivermectin Does Not Treat

Patients should understand that ivermectin is not intended for every type of infection.

It does not treat:

• COVID-19
• Influenza (flu)
• Common cold
• Bacterial infections
• Fungal infections

Only use ivermectin for conditions recommended by a qualified healthcare professional.

Why Medical Assessment Matters

The correct ivermectin dose depends on:

• Body weight
• Type of infection
• Overall health
• Liver function
• Other medicines
• Individual response to treatment

A 12 mg tablet represents the tablet strength—it does not mean everyone should take 12 mg. Your healthcare provider determines the appropriate dose and treatment schedule based on your individual needs.

Never change the dose or repeat treatment without medical advice.
