Iverjohn 12 mg: Uses, Dosage, Safety & Side Effects
Iverjohn 12 mg is a prescription medicine containing ivermectin 12 mg, an antiparasitic drug used to treat certain parasitic infections. According to the manufacturer, Iverjohn-12 contains ivermectin USP 12 mg and is intended for the treatment of parasitic infections.
Ivermectin works by affecting the nerve and muscle functions of susceptible parasites, eventually causing their paralysis and death. However, the correct dose and duration depend on the type of infection, body weight, age, medical history, and other medicines a person may be taking.
One important point is that Iverjohn 12 mg does not mean every patient should take one 12 mg tablet as a standard dose. Ivermectin dosing is commonly weight-based for several infections.
What Is Iverjohn 12 mg?
Iverjohn 12 mg is a brand of ivermectin containing 12 mg of ivermectin USP per tablet. It belongs to the antiparasitic class of medicines.
The manufacturer’s information lists Iverjohn-12 for parasitic infections and describes ivermectin as a medicine that works against susceptible worms by affecting their nerve and muscle cells.
Ivermectin tablets are used medically for certain infections, including intestinal strongyloidiasis and onchocerciasis. Other ivermectin formulations or treatment regimens may be used for certain conditions under appropriate medical guidance.
How Does Iverjohn 12 mg Work?
Iverjohn 12 mg contains ivermectin, which targets certain parasites.
Ivermectin binds to specific chloride channels found in the nerve and muscle cells of susceptible parasites. This interferes with normal nerve signaling and muscle activity, leading to paralysis and eventual death of the parasite.
Because different parasites have different characteristics, ivermectin is not appropriate for every type of infection. A healthcare professional should determine whether ivermectin is suitable for the particular infection.
Uses of Iverjohn 12 mg
Iverjohn 12 mg may be prescribed when ivermectin is appropriate for a susceptible parasitic infection.
1. Strongyloidiasis
Strongyloidiasis is an intestinal infection caused by the parasitic worm Strongyloides stercoralis.
Ivermectin is considered a first-line treatment for strongyloidiasis. CDC guidance recommends 200 micrograms per kilogram orally for 1–2 days for uncomplicated infection.
2. Onchocerciasis
Ivermectin is also used to treat onchocerciasis, commonly known as river blindness.
It kills the immature worms, called microfilariae, that contribute to symptoms. It does not kill adult Onchocerca volvulus worms. CDC recommends approximately 150 micrograms per kilogram as an oral dose, with treatment intervals determined by the clinical situation and local guidance.
3. Certain Other Parasitic Conditions
Depending on the diagnosis and local treatment guidelines, ivermectin may also be used for certain other parasitic infections. For example, CDC guidance includes oral ivermectin among treatment options for some soil-transmitted helminth infections and certain ectoparasitic conditions.
The specific condition, dose, and treatment schedule should always be confirmed by a healthcare professional.
Iverjohn 12 mg Dosage
The appropriate dose of Iverjohn 12 mg depends on the infection and the patient’s body weight.
For some approved ivermectin uses, dosing is calculated in micrograms per kilogram (mcg/kg) rather than simply prescribing a fixed number of 12 mg tablets.
For example, the DailyMed labeling for ivermectin tablets recommends approximately:
| Infection | Example ivermectin dosing |
|---|---|
| Strongyloidiasis | About 200 mcg/kg orally as a single dose |
| Onchocerciasis | About 150 mcg/kg orally as a single dose |
| Some other parasitic infections | Regimen varies according to diagnosis |
These are examples from ivermectin clinical guidance and should not be used to self-calculate a dose.
Is One 12 mg Tablet Enough?
Not necessarily.
A 12 mg tablet is simply a strength of the medicine. The required amount may be different depending on body weight and the infection being treated.
Taking additional tablets without medical advice can increase the risk of adverse effects. CDC specifically notes that higher-than-recommended ivermectin doses can increase side effects and may be harmful.
How to Take Iverjohn 12 mg
Take Iverjohn 12 mg exactly as directed by your healthcare professional.
Depending on the indication and formulation, ivermectin tablets may be recommended on an empty stomach with water. For example, DailyMed labeling for ivermectin tablets specifies administration on an empty stomach with water for strongyloidiasis and onchocerciasis.
Do not change the dose, repeat treatment, or extend treatment without medical advice.
Possible Side Effects of Iverjohn 12 mg
Iverjohn 12 mg may cause side effects in some people.
The manufacturer’s information lists possible effects including:
- Vomiting
- Dizziness
- Fever
- Joint pain
- Fatigue
- Vertigo
Clinical ivermectin labeling also reports effects such as nausea, diarrhea, abdominal discomfort, dizziness, rash, itching, and fatigue in some patients.
Side effects can also depend on the infection being treated. For example, treatment of onchocerciasis can cause reactions related to the death of microfilariae.
If symptoms are severe, persistent, or unusual, contact a healthcare professional.
Important Safety Precautions
Pregnancy
Ivermectin should not be taken during pregnancy unless a healthcare professional determines that treatment is appropriate. CDC identifies pregnancy as a relative contraindication for ivermectin treatment of strongyloidiasis and notes that data in pregnancy are limited.
Children
Safety considerations are especially important in children with low body weight. CDC notes that ivermectin safety in children weighing less than 15 kg is unclear.
Liver Problems
Tell your doctor if you have liver disease or abnormal liver function before taking ivermectin. Your medical history can influence treatment decisions.
Loa loa Infection
People who may also have Loa loa (loiasis) require special medical evaluation before ivermectin treatment for onchocerciasis because severe reactions can occur.
Other Medicines
Tell your healthcare professional about all prescription medicines, over-the-counter products, and supplements you take. This helps reduce the risk of interactions or inappropriate treatment.
Who Should Avoid Self-Medicating With Iverjohn 12 mg?
Self-treatment is particularly inappropriate when:
- The infection has not been diagnosed
- The patient is pregnant
- The patient weighs less than 15 kg
- There may be Loa loa infection
- The person has significant medical conditions
- Other medicines are being taken
- Symptoms are severe or unexplained
Ivermectin should be used for an appropriate medical indication rather than simply taking it whenever a parasitic infection is suspected.
