What is Ivermectin, and why is it used?
Ivermectin is a sort of medication that is used to treat parasitic infections.
Mainly used to treat the following:
Intestinal strongyloidiasis, a gastrointestinal illness (anguillulosis). Strongyloides stercoralis is a kind of roundworm that causes this.
Microfilaraemia, a blood illness caused by “lymphatic filariasis.” An immature worm is known as “Wuchereria bancrofti” is to blame. Adult worms are not affected by Ivermectin; only young worms are.
Mites on the skin (scabies). When microscopic mites crawl into your skin, this is what happens. This might result in a lot of irritation. Only take Ivermectin if your doctor has confirmed or suspects you have scabies.
Ivermectin won’t prevent you from contracting one of these illnesses
It is ineffective against mature worms.
Only use Ivermectin if your doctor has confirmed or suspects you have a parasite infection.
Before you start using Ivermectin, there are a few things you should know.
Ivermectin should not be used.
In general, if you have odd symptoms that appear quickly after taking a drug, such as a rash, hives, or fever, you may be allergic to that medicine.
If you have any of the symptoms listed above, you should not use Ivermectin. Before using Ivermectin, consult your doctor or pharmacist if you have any questions.
What is the best way to take Ivermectin?
Always follow pharmacist instructions. If not sure, ask the doctor.
Treatment for strongyloidiasis in the gastrointestinal tract (anguillulosis)
The suggested dose is 200 grams of Ivermectin per kilogram of body weight, given as a single dose orally.
The dosage depends on body weight, is as follows:
Body Weight (kg)
Dose (No.of 3 mg tab)
15 to 24
25 to 35
36 to 50
51 to 65
66 to 79
Microfilaraemia induced by Wuchereria bancrofti and its treatment (lymphatic filariasis)
In Wuchereria bancrofti microfilaraemia (lymphatic filariasis), a single oral dose of 150 to 200 g ivermectin per kg body weight is suggested for mass treatment campaigns every six months.
To maintain sufficient suppression of microfilaraemia in treated patients in endemic areas where therapy can only be given once per 12 months, the suggested dosage is 300 to 400 g per kg body weight.
Treated patients. Dose based on body weight.
Body Weight (Kg)
Dose (Every 6 Months) (No of 3 mg tablets)
Dose (Every 12 Months) (No of 3 mg tablets)
15 to 25
26 to 44
45 to 64
65 to 84
Alternatively, in the absence of weighing instruments, the ivermectin dosage for mass treatment campaigns can be calculated using the patient’s height, as follows:
Height (in cm)

DOSE (Every 12 Months ) (No of 3 mg tablets)
90 to 119
120 to 140

Using machinery and driving
Ivermectin’s impact on the ability to drive and operate equipment has not been investigated. It’s impossible to rule out the chance of adverse symptoms, including dizziness, sleepiness, or feeling unsteady or spinning in specific individuals, which might impair their ability to drive or operate machinery.

Before using Ivermectin, see your doctor or pharmacist if any of the following apply to you (or if you are unsure).
Ivermectin isn’t meant to be used to prevent tropical parasite infections. It is ineffective against adult parasitic worms and should only be taken when a parasitic infestation is specific or highly suspected, as advised by a doctor.
Ivermectin’s safety in youngsters weighing less than 15 kg has not been determined.
Patients who are elderly
There were insufficient numbers of participants aged 65 and up in clinical investigations with Ivermectin to establish if they respond differently than younger ones. There have been no observed variations in reactions between senior and younger patients in other therapeutic experiences. In general, older patients should be treated with caution due to the increased likelihood of impaired hepatic, renal, or cardiac function, as well as concurrent illness or other medication therapy.
