Dosage of Domphil

Your physician will recommend an ideal dose of Domphil you are to take for your medical condition.

He might use your body weight, condition severity, or age in determining the best dosage for you. This is called dose individualization.

Domperidone is better taken on an empty stomach, about 10 to 15 minutes before meal. This increases its absorption.

Domphil dosage for adults


  • Nausea and vomiting: 10mg taken 8 hourly daily
  • Gastrointestinal motility disorders: 10mg taken 8 hourly daily
  • Lactation induction or breast milk production increase: 10mg taken 8 hourly daily


30mg (one suppository) inserted 12 hourly, daily.

Dosage for Children 12 years of age and older and weighing 35 kg or more


  • Nausea and vomiting: 10mg taken 8 hourly daily
  • Gastrointestinal motility disorders: 10mg taken 8 hourly daily


30mg (one suppository) inserted 12 hourly, daily.

Dosage for children

Children weighing less than 35kg are better dosed using their body weight.

To get the right dose for any child, multiple the child’s weight in kg by 250μg. What you get should be the child dose.

For instance, a child whose body weight is 10kg should get: 250ug × 10 = 2.5kg of Domperidone. This will be equivalent to 2.5ml of Domperidone oral suspension.

Note: your doctor can recommend a high dose of Domperidone for you. In some cases, he might recommend 20mg, to be taken 3 to 4 times daily. Always adhere to your doctor’s prescription as against what you get elsewhere, including this one here.

Side Effects of Domphil

  • Drowsiness
  • Diarrhea
  • Headache

When not to use Domphil and/or when to observe caution

  1. Patients who are 60 years and older and are using Domperidone have increased risk of having serious ventricular arrhythmias and sudden cardiac death. Domperidone should, therefore, be used with caution in this type of patients.
  2. Caution should be observed in patients taking more than 30mg of Domperidone orally, daily.
  3. Domperidone should not be used together with drugs that prolong QT interval.
  4. Don’t use Domperidone in patients with heart issues unless when it is certain that benefits of doing so outweigh the risks.
  5. Don’t use in patients with significant electrolyte imbalance or disturbances
  6. There are a group of drugs called CYP3A4 inhibitors. Ask your pharmacist about them if you care to know. Please don’t use Domperidone concomitantly with them. Doing so will increase the level of Domperidone in your blood, thereby exposing you to chancing of having serious side effects.
  7. Do not exceed the recommended dose (even if you don’t feel better).

Can pregnant women take Domphil?

It is not recommended, so do not take it when you’re pregnant.

You should take note that Domperidone is not found to be teratogenic in humans but data supporting this is not enough.

Can breastfeeding women take Domphil?

If your doctor didn’t recommend it for you, for the purpose of increasing your breast milk production, please don’t use it when breastfeeding.

This is to prevent your breastfed infant from having adverse effects associated with its use.

Note: women who have used Domperidone during breastfeeding reported no adverse effects in their babies. This could be because little amount of Domperidone is secreted in breast milk.
