Mebendazole 500 mg

Mebendazole 500 mg is a benzimidazole anthelmintic medicine used to treat certain intestinal worm infections. It works primarily within the gastrointestinal tract, where it interferes with processes parasites need for survival and reproduction.  If you want to get rid of these problems, you can buy Mebendazole 500mg from Careskit.Com.

A 500 mg chewable formulation of mebendazole has been approved as Vermox for certain gastrointestinal helminth infections. FDA documentation describes the 500 mg chewable formulation as a single-dose treatment for specified soil-transmitted worm infections.

What Is Mebendazole 500 mg Used For?

Mebendazole is used against susceptible intestinal helminths. Depending on the specific formulation and regulatory labeling, it may be used for infections involving parasites such as:

• Roundworm (Ascaris lumbricoides)
• Whipworm (Trichuris trichiura)
• Hookworm
• Pinworm (Enterobius vermicularis)

The FDA-approved Vermox 500 mg chewable formulation was approved for patients aged 1 year and older for gastrointestinal infections caused by Ascaris lumbricoides and Trichuris trichiura.

Other mebendazole products have different indications. For example, the U.S. Emverm 100 mg labeling covers patients 2 years and older with gastrointestinal infections caused by pinworm, whipworm, roundworm, and hookworm.

How Does Mebendazole Work?

Mebendazole belongs to the benzimidazole class of anthelmintic medicines. Much of an orally administered dose remains in the gastrointestinal tract, where the medicine produces its antiparasitic effect.

It interferes with parasite cellular functions, particularly processes involving tubulin and nutrient utilization. This disrupts the parasite’s ability to maintain normal cellular activity and ultimately contributes to its elimination.

Mebendazole has relatively low systemic bioavailability, with most of the administered drug remaining in the gastrointestinal tract.

Mebendazole 500 mg Dosage

The appropriate dose depends on the specific mebendazole formulation, parasite being treated, patient age, and applicable product labeling.

For the FDA-approved Vermox 500 mg chewable formulation, the approved regimen is a single 500 mg dose for its specified indications. FDA review documents describe the product as a 500 mg chewable tablet intended as a one-time treatment for certain soil-transmitted helminth infections.

Do not assume that every mebendazole product uses the same dose. For example, the U.S. Emverm 100 mg product has different treatment schedules, including a single 100 mg dose for pinworm and twice-daily treatment for three days for certain other infections.

Always follow the instructions supplied with the exact product prescribed or dispensed.

How to Take Mebendazole 500 mg

Mebendazole is taken orally.

Depending on the product, the tablet may be designed to be:

• Chewed
• Swallowed
• Crushed and mixed with food

The FDA labeling for mebendazole chewable tablets states that the medicine can be taken with or without food. No routine fasting or purging is required for the labeled Emverm regimen.

For children who have difficulty chewing a 500 mg chewable formulation, FDA review documents describe a method involving softening the tablet with a small amount of drinking water before administration. The exact product instructions should always be followed.

Common Side Effects

Mebendazole is generally tolerated by many patients, but side effects can occur.

Possible adverse effects include:

• Abdominal pain
• Diarrhea
• Nausea
• Vomiting
• Flatulence
• Reduced appetite
• Rash

These reactions are reported in mebendazole labeling, although the frequency and profile can vary according to formulation, dose, and treatment duration.

Serious Side Effects and Warnings

Seek medical attention for symptoms suggesting a serious reaction, such as difficulty breathing, facial or throat swelling, severe skin reactions, unusual weakness, or other severe or persistent symptoms.

Postmarketing reports involving mebendazole formulations and regimens other than the U.S. Emverm 100 mg regimen have included rare serious reactions such as neutropenia, agranulocytosis, hepatitis, abnormal liver tests, glomerulonephritis, seizures, Stevens-Johnson syndrome, toxic epidermal necrolysis, and severe allergic reactions.

Higher-than-recommended doses or prolonged treatment have also been associated with adverse effects including reversible liver-enzyme elevations, hepatitis, blood-cell abnormalities, and kidney inflammation.

Mebendazole 500 mg Precautions

Before using mebendazole, tell your healthcare professional if you:

• Have previously experienced an allergy to mebendazole.
• Have liver disease or abnormal liver tests.
• Are pregnant or planning pregnancy.
• Are breastfeeding.
• Are taking prescription or nonprescription medicines.
• Are treating a young child.
• Have previously received prolonged or repeated antiparasitic treatment.

The medicine should be used according to the appropriate age and product-specific labeling.

Mebendazole and Metronidazole Interaction

One particularly important interaction involves metronidazole.

The FDA labeling warns against taking mebendazole with metronidazole because serious skin reactions, including Stevens-Johnson syndrome and toxic epidermal necrolysis, have been reported with the combination.

Tell your doctor or pharmacist about all medicines you take before starting mebendazole.

Mebendazole 500 mg During Pregnancy

If you are pregnant or planning to become pregnant, discuss mebendazole treatment with a healthcare professional before taking it.

The FDA patient information states that it is not known whether Vermox can harm an unborn baby. Treatment decisions should therefore consider the confirmed infection, pregnancy stage, available alternatives, and expected benefits and risks.

Do not self-treat suspected worm infections during pregnancy without appropriate medical advice.

Mebendazole and Breastfeeding

Limited information indicates that small amounts of mebendazole can enter human milk. The available data are insufficient to establish the full risk to a breastfed infant.

Patients who are breastfeeding should discuss treatment with their healthcare professional to determine the most appropriate approach.

Mebendazole 500 mg for Children

Age recommendations depend on the specific product.

The FDA-approved Vermox 500 mg chewable formulation was approved for patients 1 year of age and older for its specified indications.

By comparison, U.S. Emverm 100 mg labeling is indicated for patients 2 years and older. Mebendazole should therefore not be administered to a child simply because another mebendazole formulation has a particular age indication.

Missed Dose

The instructions for a missed dose depend on the treatment regimen.

If the prescribed treatment consists of a single 500 mg dose and it was not taken as scheduled, contact the prescribing healthcare professional or pharmacist for instructions.

Do not automatically take an additional dose to compensate for a missed dose unless specifically advised to do so.

Mebendazole 500 mg Overdose

Taking substantially more mebendazole than recommended, particularly for prolonged periods, can increase the risk of adverse effects.

Reported effects associated with excessive or prolonged exposure include gastrointestinal symptoms, liver-enzyme abnormalities, hepatitis, hair loss, neutropenia, agranulocytosis, and glomerulonephritis.

If an overdose is suspected, contact a healthcare professional or poison-control service promptly.

Storage

Storage requirements depend on the specific manufacturer and formulation.

Follow the product label for:

• Temperature
• Moisture protection
• Container requirements
• Expiration date
• Disposal instructions

For example, the U.S. Emverm 100 mg product is stored at controlled room temperature of 20°C to 25°C (68°F to 77°F).

Mebendazole 500 mg vs. 100 mg

Mebendazole is available in different strengths and formulations, and the strength alone does not determine the appropriate treatment schedule.

A 500 mg chewable formulation may be designed for a single-dose regimen for particular infections, while the 100 mg formulation can have different dosing schedules depending on the parasite.

Therefore, 500 mg should not simply be substituted for 100 mg, and the treatment schedule should always correspond to the exact product and diagnosed infection.
