Ivermectin 6 mg tablet dose is a well-established medication with a long track record of treating various parasitic infections in both humans and animals. Since its discovery in the late 1970s, ivermectin has become a cornerstone in global health, especially in efforts to control diseases like onchocerciasis (river blindness) and lymphatic filariasis. But with its expanded use in recent years—and some controversy surrounding off-label applications like COVID-19—many people are asking: Is ivermectin safe?
In this article, we’ll explore the benefits, risks, and side effects of ivermectin to help you make informed decisions under proper medical guidance.
What Is Ivermectin?
Ivermectin is an antiparasitic medication that works by interfering with the nervous system and muscle function of certain parasites, causing paralysis and death. You can also buy ivermectin online from dosepharmacy. It is effective against a variety of parasites, including:
- Intestinal worms (e.g., Strongyloides stercoralis)
- Skin parasites (e.g., lice, scabies)
- Bloodborne parasites (e.g., Onchocerca volvulus, which causes river blindness)
Ivermectin is included in the World Health Organization’s List of Essential Medicines and is available in tablets, topical creams, and injectable forms.
What Is Ivermectin Used For in Humans?
Ivermectin has proven benefits in treating and controlling a range of parasitic diseases. Some common human uses include:
1. Scabies
Scabies is a skin infestation caused by the Sarcoptes scabiei mite. Ivermectin is highly effective, especially in cases where topical treatments have failed or in outbreaks involving multiple people.
2. Head Lice
Ivermectin can be used when other lice treatments fail, typically in the form of a lotion or oral tablet.
3. Strongyloidiasis
A parasitic roundworm infection found in the intestines, strongyloidiasis can be chronic and dangerous if left untreated. Ivermectin is the drug of choice.
4. Onchocerciasis (River Blindness)
This disease is caused by a filarial worm transmitted by blackflies. Ivermectin reduces microfilariae in the skin and eyes, helping prevent blindness.
5. Lymphatic Filariasis
Also known as elephantiasis, this condition is treated as part of mass drug administration programs using ivermectin in combination with other antiparasitic agents.
How Does Ivermectin Work?
Ivermectin works by binding to specific channels (called glutamate-gated chloride channels) in nerve and muscle cells of parasites. This action increases permeability to chloride ions, leading to paralysis and death of the parasite. Importantly, human nerve cells are protected by the blood-brain barrier, which limits ivermectin’s access to the central nervous system, making the drug safe when used correctly.
Is Ivermectin Safe?
✅ Generally Yes—When Used as Prescribed
When taken at the recommended dose and under medical supervision, ivermectin is considered very safe for most people. It has been widely used for decades in mass treatment programs involving millions of individuals with very low rates of serious adverse events.
The safety of ivermectin is supported by clinical trials, long-term data, and the experience of global health programs. However, like any medication, it is not completely risk-free.
Potential Side Effects of Ivermectin
Most side effects of ivermectin are mild and temporary, especially when treating common parasitic infections. Common side effects may include:
- Dizziness
- Headache
- Nausea
- Diarrhea
- Fatigue
- Mild skin rash
These side effects typically resolve on their own as your body clears the dead parasites and adjusts to the medication.
⚠️ More Serious Side Effects (Less Common)
- Allergic reactions: Some individuals may develop rash, itching, or swelling—particularly in response to dying parasites, not the drug itself.
- Eye problems: In rare cases, especially when treating onchocerciasis, eye inflammation may occur.
- Hypotension (low blood pressure): This may lead to dizziness or fainting.
- Liver enzyme elevations: Ivermectin can affect liver function in some individuals, so people with liver disease should use it cautiously.
- Neurotoxicity: Although rare, high doses or incorrect use (especially in veterinary formulations) can cause confusion, tremors, or seizures.
Who Should Avoid Ivermectin?
While ivermectin is safe for many, it may not be suitable for everyone. Caution or medical consultation is advised for:
- Pregnant or breastfeeding women: Safety data is limited.
- Children under 15 kg (about 33 lbs): Lower-weight infants may need special consideration.
- People with liver disease: Liver function should be monitored.
- Individuals taking blood thinners or other medications: Drug interactions can occur.
- Those with compromised immune systems: Higher risk of side effects or complications.
Ivermectin and COVID-19: What’s the Controversy?
During the COVID-19 pandemic, ivermectin was promoted in some circles as a potential treatment or preventive measure. However, major health authorities—including the World Health Organization (WHO), U.S. Food and Drug Administration (FDA), and Centers for Disease Control and Prevention (CDC)—do not recommend ivermectin for COVID-19 outside of clinical trials.
The evidence supporting its use against COVID-19 is inconsistent and largely based on poorly designed studies. In some cases, people misused veterinary ivermectin formulations, leading to overdoses and serious harm. This misuse sparked public concern and widespread debate.
Key point: Ivermectin is not approved for treating or preventing COVID-19. Do not self-medicate without medical guidance.
How to Take Ivermectin Safely
To ensure maximum benefit and reduce risks:
- Take the exact dose prescribed by your healthcare provider.
- Avoid using veterinary versions of ivermectin intended for animals.
- Take with water on an empty stomach, unless directed otherwise.
- Follow hygiene measures (especially in scabies or lice) to prevent reinfection.
- Store properly and keep out of reach of children.
- Inform your doctor of all medications, supplements, and health conditions you have.
Benefits of Ivermectin in Public Health
Ivermectin has contributed significantly to global health, especially in under-resourced regions. Its benefits include:
- Reducing blindness in millions through onchocerciasis programs
- Improving quality of life by controlling disfiguring diseases like lymphatic filariasis
- Providing an affordable and accessible treatment for common parasitic infections
The Nobel Prize in Physiology or Medicine in 2015 was awarded to scientists who discovered and developed ivermectin—a testament to its global importance.
Ivermectin is a safe and effective medication when used for its intended purposes and under proper medical supervision. It has transformed the treatment of parasitic diseases worldwide and continues to be a vital tool in global health. However, like any medication, it must be used responsibly, with a clear understanding of its benefits, potential risks, and side effects.
Avoid self-medicating, especially with non-human formulations or for unapproved conditions like COVID-19. If you suspect a parasitic infection or have been prescribed ivermectin, talk to your healthcare provider to ensure it’s the right choice for you.
