mebex (MEBENDAZOLE)

What is Mebex?

Mebex is an anthelmintic (anti-worm) medication used to treat intestinal worm infections like pinworms, roundworms, whipworms, and hookworms. It works by preventing the worms from absorbing sugar (glucose), which they need to survive. Over time, this causes the worms to die and pass out of the body through bowel movements.

What is the usual dose of Mebex?

For adults and children over 2 years old, the usual dose depends on the infection:

• Pinworms: A single dose of 100 mg, repeated after 2 weeks if needed.
• Other worms (roundworms, whipworms, hookworms): 100 mg twice daily for 3 days.
  Children under 2 years old should not take Mebex unless advised by a doctor.

How do I take Mebex?

Mebex is usually taken by mouth as a chewable tablet or liquid. It can be taken with or without food. The tablet should be chewed completely before swallowing. No special diet is required, but maintaining good hygiene (like washing hands and cleaning bedding) helps prevent reinfection.

For how long do I take Mebex?

The duration of treatment depends on the type of worm infection:

• Pinworm infections: A single dose, repeated after two weeks if reinfection occurs.
• Other worm infections: Taken for 3 consecutive days.
  Follow your doctor's advice, and if symptoms persist, a second course of treatment may be needed.

What is Mebex used for?

Mebex is used to treat infections caused by intestinal worms, including:

• Pinworms (Enterobiasis)
• Roundworms (Ascariasis)
• Whipworms (Trichuriasis)
• Hookworms (Ancylostomiasis and Necatoriasis)
  It helps eliminate these parasites by preventing them from absorbing nutrients, leading to their death.

How long does it take for Mebex to start working?

Mebex starts working within a few hours of taking the dose, but it may take a few days to a week for worms to be fully cleared from the intestines. Some people may see dead worms in their stool within 1–3 days after taking the medication.

Is Mebex effective?

Yes, Mebex is highly effective against most intestinal worms, with cure rates of 90% or higher in many cases. However, reinfection is common, especially with pinworms, so hygiene measures (like washing hands, cleaning clothes, and trimming fingernails) are necessary to prevent worms from returning.

How does one know if Mebex is working?

You will know Mebex is working when symptoms improve, such as reduced itching, stomach pain, or diarrhea. Dead worms may be seen in stool after a few days. If symptoms persist after 3 weeks, consult a doctor to check if a second dose is needed.

How does Mebex work?

Mebex works by blocking the worms' ability to absorb glucose (sugar). Since worms rely on glucose for energy, they become weaker, unable to move, and eventually die. The dead worms are then expelled naturally from the body through bowel movements.

Who should avoid taking Mebex?

People who should avoid Mebex include:

• Pregnant women (especially in the first trimester)
• Children under 2 years old, unless advised by a doctor
• Those with severe liver disease
• People allergic to Mebex or similar drugs

Always consult a doctor before use.

Can I take Mebex with vitamins or supplements?

Yes, Mebex does not have major interactions with most vitamins or supplements. However, it is recommended to avoid high-fat meals and grapefruit juice, as they can affect absorption. If taking iron supplements, consult your doctor, as some anthelmintics can lower iron levels.

Can I take Mebex with other prescription drugs?

Mebex may interact with:

• Metronidazole (Flagyl) – increases risk of serious skin reactions
• Cimetidine (for acid reflux) – may increase Mebex levels in the blood
• Anticonvulsants (like carbamazepine) – may reduce effectiveness of Mebex
  Always inform your doctor about other medications before taking Mebex.
