Mebendazole - oral

Patient Medicine Information
Why do I need this medicine?
Mebendazole is used to treat parasitic worm infections such as roundworm, hookworm, whipworm, and pinworm that infect the intestines.
How do I take this medicine?
Take Mebendazole exactly as directed by your doctor or according to the instructions on the label. Do not take more or less than instructed by your doctor.

You may take this medicine with or without food. Try to take it at the same time each day.

Mebendazole is available as a tablet, chewable tablet, or oral suspension.

If you are taking the tablet, you may chew or swallow the tablet whole. If you have difficulty swallowing the tablet(s), you may crush the tablet(s) and mix it with food.

If you are given the chewable tablet, chew the tablet completely before swallowing. Do not swallow the tablet whole. If you have difficulty swallowing, place the tablet in a spoon and add 2-3 mL of water. Within 2 minutes, the tablet will absorb the water and turn into a soft semi-solid mass, which can then be swallowed.

If you are taking an oral suspension, shake the bottle well before you take it to ensure that the liquid is evenly mixed. Use the measuring spoon or cup provided to measure your dose.

The dose of this medicine will be decided by your doctor. Your doctor will advise you on the treatment timeframe depending on the type and severity of your condition.

Take Mebendazole at regular intervals. Do not skip any doses. You must complete the entire course of this medicine. If you don't, the infection will not be properly controlled.
What should I do if I have forgotten to take this medicine?
Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and return to your normal dosing schedule.

DO NOT double a dose under any circumstances.

If you often forget to take your medicine, let your doctor and pharmacist know.
When should I not use this medicine?
Do not use Mebendazole if you ever had an allergic reaction (e.g. rashes, breathlessness, swollen eyes) to this medicine or any of its ingredients.

Do not take Mebendazole if you are pregnant or planning to have a baby soon. If you become pregnant while being treated with this medicine, alert your doctor immediately. Mebendazole may cause harm to your unborn child. You must use proven birth control methods while taking this medicine.

Do not take Mebendazle with metronidazole (antibiotic).
What should I take note of while taking this medicine?
Inform your doctor if you have the following conditions:
  • Crohn's ileitis (a long-term inflammatory disease that affects the ileum [the last part of the small intestine])
  • ulcerative colitis (a disease that causes inflammation and sores in the linings of the large intestine and rectum)
  • liver disease
Let your doctor know if you are breastfeeding.

Be sure to check with your doctor or pharmacist before giving this medicine to a child.

If you are taking Mebendazole at higher doses or for longer periods, you may need to have regular blood tests to check your body's response to the medicine. Your doctor will advise you about how often you need to have blood tests.

Practice good hygiene to reduce the chances of getting infected again. Wash your hands before eating and after using the toilet.
What side effects could I experience?
Mebendazole may cause any of the following side effects: abdominal pain, diarrhoea, stomach wind, loss of appetite, nausea, vomiting, dizziness, hair loss, and rash.

Some side effects may need immediate medical help. Alert your doctor quickly if you experience rashes with peeling of the skin or blistering of the lips, mouth or eyes accompanied by fever.

This medicine may cause the level of your white blood cells to drop.

White blood cells help your body to fight infections. A fall in the level of your white blood cells may put you at higher risk for infections, such as coughs, colds and flu, which may lead to more serious infections. Avoid crowded places and people who are sick. Inform your doctor if you have a fever, or a cough or flu that does not go away.

Inform your doctor if any of these side effects do not go away or are severe, or if you experience other side effects.
Can I take this with other medicines?
Do not take Mebendazole if you are taking metronidazole (antibiotic).

Inform your doctor and pharmacist if you are taking cimetidine (medicine that reduces stomach acid production).

Always notify your doctor and pharmacist if you are taking any other medicines, including herbal tonics such as traditional Chinese medicines, supplements, and medicines that you buy without a prescription.
What special dietary instructions should I follow?
Avoid alcohol.
How should I store this medicine?
Store in a cool, dry place away from the reach of children.

Medicines must not be used past the expiry date.
