Dr. Arjun Srivastav What Is Ivermectin 3 mg Tablet?
Ivermectin 3 mg is an oral tablet containing 3 mg of ivermectin, an antiparasitic medicine belonging to the avermectin group. For a broader explanation of the medicine, see our guide on what ivermectin is and how it works.
The medicine acts on specific targets involved in the nerve and muscle function of susceptible parasites. This interferes with normal signalling in the parasite and can lead to paralysis and death.
The 3 mg strength does not mean that every person should take one tablet. Ivermectin doses vary according to the infection being treated and, for some conditions, the patient’s body weight. Your prescribed dose should therefore be followed rather than selected based only on the tablet strength.
🔔 Reminder
Ivermectin 3 mg is not a fixed one-tablet dose for everyone. The appropriate number of tablets depends on the prescribed dose, the condition being treated, and, for some conditions, body weight.
Ivermectin 3 mg Tablet Uses
The main ivermectin 3 mg tablet uses involve specific parasitic infections. You can also learn more about what ivermectin is used for and the conditions it may be prescribed to treat.
Ivermectin may be prescribed for:
- Intestinal strongyloidiasis caused by Strongyloides stercoralis
- Onchocerciasis, also known as river blindness
- Human sarcoptic scabies in appropriate circumstances
- Crusted scabies, where oral ivermectin is used with topical treatment
Ivermectin is not suitable for every type of parasite. The appropriate medicine depends on the infection and the clinical assessment.
Ivermectin 3 mg for Scabies
Scabies is a contagious skin infestation caused by the Sarcoptes scabiei mite. Common symptoms include an itchy rash, with itching often becoming worse at night.
Oral ivermectin may be prescribed for human sarcoptic scabies when prior topical treatment has failed or is contraindicated. For crusted scabies, ivermectin is used together with topical treatment. If you are wondering how quickly treatment works, read our guide on whether ivermectin kills scabies immediately for more information about symptom persistence and treatment response.
For human sarcoptic scabies, oral ivermectin may be prescribed in certain circumstances, including when topical treatment has failed or is contraindicated.
How Does Ivermectin 3 mg Work?
Ivermectin acts on specific chloride channels involved in the nervous system of susceptible parasites.
By increasing chloride ion movement across the parasite’s nerve and muscle cell membranes, ivermectin disrupts normal nerve signalling. This can cause paralysis and eventually death of the susceptible parasite.
The medicine therefore targets the parasite rather than simply relieving symptoms caused by the infection.
Ivermectin Scabies Dosage 3 mg
The ivermectin scabies dosage of 3 mg is based on body weight rather than a fixed number of tablets for everyone.
Australian product information describes a target dose of approximately 200 micrograms of ivermectin per kilogram of body weight per dose for scabies. Because each tablet contains 3 mg, the number of tablets needed varies according to the patient’s weight.
For typical scabies, Australian product information describes two doses, with the second dose given between day 8 and day 15. The treatment plan may differ according to the patient’s circumstances and the healthcare professional’s assessment.
How Many Ivermectin 3 mg Tablets Are Needed for Scabies?
There is no single tablet quantity that applies to every patient.
The prescribed amount is determined primarily by body weight and the clinical situation. For people at higher body weights, the dose is calculated to achieve the appropriate weight-based amount rather than simply applying a fixed lower range.
Do not use online dosing information to decide how many ivermectin tablets to take or when to repeat treatment. Your doctor or pharmacist should provide your individual dose and treatment schedule.
If topical treatment is prescribed for scabies, use it exactly as directed.
Ivermectin 3 mg Dosage for Other Infections
Ivermectin dosing differs between infections, so a dose used for one condition should not automatically be used for another.
Strongyloidiasis
For intestinal strongyloidiasis, Australian product information specifies a target dose of approximately 200 micrograms per kilogram of body weight. Treatment is generally given as an oral dose, with follow-up assessment or testing used when appropriate to determine whether treatment has been successful.
Onchocerciasis
For onchocerciasis, the target dose is approximately 150 micrograms per kilogram of body weight. Further treatment may be required depending on the patient’s circumstances and medical advice.
Because ivermectin dosing varies according to the condition and patient factors, see our guide to ivermectin dosage and safety information for additional information.
How to Take Ivermectin 3 mg Tablets
Take ivermectin exactly as prescribed by your healthcare professional.
Australian consumer medicine information instructs patients taking Stromectol to take the prescribed dose with a full glass of water. The number of tablets depends on the prescribed dose.
Important points
- Take only the prescribed amount.
- Take the tablets with water as directed.
- Do not repeat treatment unless instructed to do so.
- Do not give your medicine to another person.
- Tell your doctor or pharmacist about other medicines and supplements you take.
- Follow any additional topical treatment prescribed for scabies.
- Attend follow-up appointments or testing when recommended.
How Long Does Ivermectin 3 mg Take to Work?
The response to ivermectin varies depending on the infection being treated.
With scabies, treatment can eliminate susceptible mites, but itching may continue after treatment because the skin can remain inflamed. Continued itching does not automatically mean that another dose is needed.
For strongyloidiasis, follow-up stool testing may be recommended to determine whether the infection has cleared.
If symptoms continue or worsen, speak with your healthcare professional rather than taking another dose yourself.
Ivermectin 3 mg Side Effects
Like other medicines, ivermectin can cause side effects. The effects experienced can vary depending on the condition being treated and the individual’s response to treatment. For a more detailed overview of possible reactions, see our guide to ivermectin side effects.

- Prescription medicines

Do not stop a prescribed medicine because of a possible interaction. Ask your doctor or pharmacist whether your medicines can be taken together safely.
Ivermectin 3 mg for Strongyloidiasis
Strongyloidiasis is an intestinal infection caused by Strongyloides stercoralis. Some people may have few or no symptoms, while others can develop gastrointestinal or skin-related symptoms.
Ivermectin is an established treatment for intestinal strongyloidiasis. The dose is based on body weight, and follow-up testing may be recommended to confirm treatment success.
Ivermectin 3 mg for Onchocerciasis
Onchocerciasis, commonly called river blindness, is a parasitic infection caused by Onchocerca volvulus.
Ivermectin acts against susceptible stages of the parasite. Dosing is calculated according to body weight, and repeat treatment may be recommended according to the patient’s circumstances.
Ivermectin 3 mg vs Ivermectin 6 mg
| Feature | Ivermectin 3 mg | Ivermectin 6 mg |
|---|---|---|
| Active ingredient | Ivermectin | Ivermectin |
| Amount per tablet | 3 mg | 6 mg |
| Medicine type | Oral antiparasitic | Oral antiparasitic |
| Dose | Weight/condition dependent | Weight/condition dependent |
A 6 mg tablet is not automatically a more appropriate treatment. The correct strength depends on the dose prescribed for the particular infection.
Ivermectin 3 mg vs Mebendazole
Ivermectin and mebendazole are both antiparasitic medicines, but they are not interchangeable.
Mebendazole is used for certain intestinal worm infections, while ivermectin has specific uses, including strongyloidiasis, onchocerciasis, and selected cases of scabies.
The appropriate medicine depends on the parasite causing the infection. Ivermectin and other antiparasitic medicines can differ considerably in their uses and treatment approaches. For another comparison, see our guide to the difference between ivermectin and fenbendazole.
Ivermectin 3 mg vs Albendazole
Albendazole and ivermectin have different therapeutic uses and should not be treated as substitutes for one another.
Albendazole is used for selected parasitic worm infections, while ivermectin is used for specific infections such as strongyloidiasis and onchocerciasis and for certain cases of scabies.
A healthcare professional should determine which antiparasitic medicine is appropriate for the diagnosed infection.
