Ivermectin, known by the brand name Stromectol, is one of the most widely used anti-parasite medicines worldwide. It helps treat several parasitic worm infections that affect the skin, intestinal tract, and bloodstream. Because parasitic diseases are common in many regions and can cause serious complications if untreated, a reliable medication with a predictable track record matters. Ivermectin fills that role well. This guide explains what the drug does, how it is prescribed, how online prescribing works, who can take it, and what questions patients most often ask. By the end, you will have a practical understanding of how Ivermectin functions and how doctors typically use it.
Ivermectin belongs to a drug class called anthelmintics, meaning medicines that kill parasites, specifically worms. The drug works by disrupting the nerve and muscle function of targeted parasites. Once the medication binds to specific channels in the parasite’s nervous system, the parasite becomes paralyzed and eventually dies. Humans do not have those channels in the same way, so the medication has a favorable safety profile when used at proper doses. Stromectol tablets contain Ivermectin for use in people. Other formulations exist for animals, but those are not interchangeable and should never be used in place of human medication.
The most common conditions treated with Ivermectin include strongyloidiasis, onchocerciasis, scabies, and lice infestations. Strongyloidiasis is an intestinal worm infection caused by Strongyloides stercoralis. Onchocerciasis, sometimes known as river blindness, is caused by Onchocerca volvulus, a parasitic worm transmitted by blackflies. Scabies is caused by Sarcoptes scabiei, a microscopic mite that burrows into the skin. Head lice infestations occur when parasitic insects live on the scalp. Although these infections differ in how they spread and what symptoms they cause, many respond well to Ivermectin because the drug affects a wide range of parasites with similar vulnerabilities.
When healthcare providers prescribe Stromectol, they typically calculate the dose based on the patient’s body weight. Most prescriptions follow a single-dose model, although some conditions require repeat treatment. A typical dose ranges from 150 to 200 micrograms per kilogram of body weight, but the exact amount depends on the condition being treated. For example, strongyloidiasis usually involves a single dose, while onchocerciasis often requires a dose once or twice per year to reduce the parasite load. Scabies, when treated with oral Ivermectin, may require two doses spaced one to two weeks apart. Because parasitic infections vary widely in severity, doctors adjust treatment plans accordingly.
What Ivermectin Treats
Below is a quick reference list of common parasitic conditions treated with Ivermectin:
Internal parasitic worms
Strongyloides
Onchocerca
Ascaris (in some cases)
Trichuris (sometimes in combination therapy)
External parasites
Scabies mites
Head lice
Body lice
Certain other ectoparasites depending on clinical judgment
Not every worm infection responds to Ivermectin. Tapeworms and flukes, for example, typically require different medications. Doctors decide based on the parasite type, symptoms, exposure history, and test results.
Ivermectin Prescription Basics
Getting a prescription for Stromectol depends on the diagnosis. Healthcare providers use a combination of symptoms, patient history, and diagnostic tests to determine whether Ivermectin is appropriate.
Typical steps a provider may follow:
Evaluate symptoms
Gastrointestinal discomfort
Rash or skin lesions
Itching
Visible parasites
Travel or exposure history
Order diagnostic tests if needed
Stool tests for worms
Skin scrapings for scabies
Blood tests for microfilariae
Visual inspection for lice
Confirm the parasite type
Accurate identification ensures the medication chosen matches the parasite.
Determine dosage
Based on body weight
Based on severity
Based on single-dose versus repeat-dose needs
Provide guidance
When to take the medication (often on an empty stomach)
What side effects to monitor for
When follow-up is needed
Because Ivermectin can interact with certain medical conditions, the doctor may ask about neurological diseases, liver problems, or recent treatments that could conflict with this medication.
Prescribing Ivermectin Online
Online prescribing has become more common, especially for conditions that are easy to diagnose remotely. Scabies and lice, for instance, can often be evaluated using photos, symptom descriptions, and history of exposure. However, intestinal or blood-borne parasites usually require lab testing, which means online prescribing may still involve in-person steps.
How online prescribing typically works
Medical questionnaire
Patients describe symptoms, medical history, weight, allergies, and possible exposures.
Consultation with a licensed provider
This may be a video visit, chat consultation, or secure message exchange.
Upload of photos (when needed)
Useful for scabies rashes, lice, or visible skin lesions.
Diagnosis and treatment plan
If the provider decides Ivermectin is appropriate, they issue a digital prescription.
Pharmacy delivery or local pickup
Patients can choose the method they prefer.
Advantages of online prescribing
Faster access for common parasitic conditions
No need for an office visit in mild cases
Easy follow-up and refill management
Clear written instructions through patient portals
Limitations
Some parasite infections require lab confirmation
Certain symptoms need in-person examination
Severe cases demand direct medical supervision
Not all online services treat parasitic diseases
Even with online options available, patients should choose reputable services that use licensed medical professionals. Parasitic infections are treatable, but only when the right medication is used correctly.
Anti-Parasite Effects of Ivermectin
Ivermectin targets parasites in two main ways. It paralyzes them, and then it disrupts their ability to reproduce or survive inside the human host. Because the drug concentrates well in tissues, it affects both internal and external parasites.
Key anti-parasitic effects
Paralysis of worms and mites
Caused by binding to glutamate-gated chloride channels in the parasite’s nerve cells.Reduction in parasite burden
Helps the immune system clear remaining organisms.Lowered transmission risk
In conditions like onchocerciasis, reducing microfilariae prevents spread to others.
Conditions where Ivermectin works best
Intestinal parasites with uncomplicated infection
Skin parasites that have not responded to topical treatments
Recurrent scabies outbreaks in communities
Patients unable to use creams or lotions for scabies
Head lice in cases where other treatments failed
How to Take Ivermectin
Doctors usually give very clear instructions for how to take the medication.
General guidance
Take Ivermectin on an empty stomach.
Swallow the tablet with a full glass of water.
Do not crush unless advised by a doctor.
Follow timing exactly, especially with multi-dose schedules.
For internal parasites
Usually one single dose
Occasionally repeated after 1–2 weeks depending on the condition
For scabies
One dose
Second dose after 7–14 days
Sometimes combined with a topical cream for severe cases
For lice
One oral dose
Repeat after 7 days if needed
Used when topical treatments fail or when infestations are widespread
Side Effects
Most people tolerate Ivermectin well, but side effects can occur.
Common mild effects
Headache
Dizziness
Nausea
Mild abdominal discomfort
Fatigue
Less common effects
Skin rash
Joint or muscle pain
Swelling of lymph nodes
Eye irritation (mostly in onchocerciasis treatment due to dying microfilariae)
Seek medical attention for:
Severe rash
Confusion
Trouble breathing
Persistent vomiting
Vision changes
These severe reactions are uncommon, but patients need to know the warning signs.
Drug Interactions and Precautions
Before taking Ivermectin, the healthcare provider reviews any medications the patient already uses. Although interactions are not widespread, some exist.
Possible interactions
Sedatives
Certain anticonvulsants
Drugs that affect liver enzymes
Blood thinners in rare cases
Other anti-parasitic drugs when taken at the same time
Precautions
Not generally recommended during pregnancy unless benefits outweigh risks
Caution with liver disease

FAQs About Ivermectin (Anti-Parasite Use Only)
How long does Ivermectin take to work?
For internal parasites, improvement often starts within a few days. For scabies, itching can continue for weeks even after successful treatment because the skin takes time to heal.
Can Ivermectin kill all worms?
No. It is effective against several types but not all. Tapeworms and flukes require different medications.
Can I take it with food?
Most doctors recommend taking it on an empty stomach to support proper absorption.
Do pets take the same Ivermectin?
No. Veterinary Ivermectin comes in different strengths and forms. Never use animal formulations in humans.
Can scabies return after treatment?
Yes. Reinfection is common in households. All close contacts should be treated when possible.
Does the medicine kill eggs?
In some parasites the drug affects larvae more than eggs, which is why repeat dosing is common.
How do I know if treatment worked?
The doctor may order follow-up tests or rely on symptom improvement depending on the condition.
Can children take Ivermectin?
Only if they meet minimum weight requirements and a healthcare provider approves it.
Why do I need a prescription?
Parasite type, dose calculation, and safety checks require medical assessment. Self-treating is risky.
Can Ivermectin be used as a preventive medicine?
Only in specific cases such as mass treatment programs in regions with endemic onchocerciasis, and only under professional supervision.
