What is Metvi tablet?
Metvi tablet is a medicine that kills parasitic worms. It's mainly used to treat strongyloidiasis (an intestinal worm infection) and onchocerciasis (river blindness). For strongyloidiasis, it kills the worms in your intestines. In river blindness, it kills the developing worms, but not the adult ones. It can also help with some other roundworm infections, lice (tiny insects that infest the skin and hair), and scabies (a skin infection caused by a tiny mite). Essentially, Metvi tablet targets different types of parasites depending on the infection being treated. Remember, this information is for general knowledge and you should always consult a doctor before using any medication.
What is the usual dose of Metvi tablet?
Metvi tablet doses vary greatly depending on age. For adults, studies have used anywhere from 30 to 120 milligrams (mg) at once. Some studies used a much smaller single dose of 12 mg. There's no established safe and effective dose for children under 22 pounds (15 kilograms kg). Milligrams (mg) and kilograms (kg) are units of weight. A milligram is a thousandth of a gram, and a kilogram is a thousand grams. Micrograms (mcg) are one millionth of a gram; so 165 mcg/kg means 165 micrograms of Metvi tablet per kilogram of body weight.
How do I take Metvi tablet?
Metvi tablet tablets should be taken on an empty stomach with water. This means you should take them at least one hour before or two hours after eating a meal. Following this instruction helps your body absorb the medication more effectively. Unless your doctor tells you otherwise, you can continue your regular diet. There are no dietary restrictions associated with Metvi tablet, aside from the timing of meals relative to taking the medication.
For how long do I take Metvi tablet?
Treatment typically involves a single dose, but for onchocerciasis, repeat doses may be needed every 3, 6, or 12 months to manage infections. Follow-up stool tests or evaluations are often required to confirm eradication in strongyloidiasis.
What is Metvi tablet used for?
Metvi tablet is a medicine used to treat several infections caused by tiny worms called nematodes (roundworms). It effectively treats intestinal strongyloidiasis, an infection of the intestines. It also helps with onchocerciasis (river blindness), although it doesn't kill the adult worms. Metvi tablet can also be used for other roundworm infections, head lice, and scabies (a skin infection caused by a mite). Essentially, it's a versatile drug against various parasitic infections.
How long does it take for Metvi tablet to start working?
Metvi tablet begins working within a few hours after ingestion. Improvement in symptoms or reduction in parasite counts is usually observed within days to weeks, depending on the infection.
Is Metvi tablet effective?
Metvi tablet is effective against certain parasitic worms. Studies show it can cure strongyloidiasis (a parasitic worm infection) in 64-100% of cases with a single dose. For onchocerciasis (river blindness), a single dose significantly reduces the number of parasitic larvae in the skin, although it doesn't kill the adult worms. Compared to other anti-parasitic drugs like albendazole and thiabendazole, Metvi tablet is better for strongyloidiasis and equally effective for some cases. Microfilariae are the larval stage of parasitic worms. mcg/kg refers to the dosage of the medicine – micrograms (mcg) per kilogram (kg) of body weight.
How does one know if Metvi tablet is working?
Metvi tablet's safety and effectiveness have been studied. Tests show it doesn't damage DNA (genotoxicity). While we lack enough data on children and the elderly, studies haven't shown different effects between age groups. The body processes Metvi tablet mainly through the liver enzyme CYP3A4 (a protein that breaks down drugs). Common side effects include tiredness, stomach pain, nausea, dizziness, and skin problems. Finally, confirming the elimination of a specific parasitic worm infection (strongyloidiasis) needs a stool test.
How does Metvi tablet work?
Metvi tablet is a medicine that kills parasitic worms (anthelmintic). It works differently depending on the infection. For strongyloidosis (a worm infection in the gut), it kills the worms in the intestines. For onchocerciasis (river blindness), it kills developing worms, but not the adult ones. After you swallow it, the amount of Metvi tablet in your blood is directly related to the dose you take. Your liver breaks it down mostly, and you eliminate most of it through your bowel movements over about 12 days. It takes about 18 hours for half the medicine to leave your body (plasma half-life). Eating a fatty meal significantly increases how much of the medicine your body absorbs – about 2.5 times more. CYP3A4 refers to a specific liver enzyme involved in breaking down many medications.
