What EMEND capsules are used for

EMEND 80mg and 125mg hard capsules are used to help prevent nausea and vomiting caused by chemotherapy.

The medicine is used in adults and adolescents aged 12 years and older. It is usually part of a wider anti-sickness treatment plan.

EMEND is not described here as a treatment for nausea from other causes. If you are unsure why it has been prescribed, check with your healthcare professional.

How EMEND works

The active ingredient in EMEND is aprepitant. It belongs to a group of medicines called NK1 receptor antagonists.

Aprepitant works by blocking the action of substance P, a chemical involved in nausea and vomiting signals in the brain. This helps reduce the chance of feeling sick around chemotherapy treatment.

EMEND is often used together with other anti-sickness medicines as part of a planned regimen.

How EMEND is usually taken

The exact schedule should always be followed as prescribed. The leaflet information commonly describes use around chemotherapy, with doses taken on specific days.

  • 125 mg on the first day of chemotherapy
  • 80 mg on the following days, if prescribed

Timing matters with this medicine, so it is important to follow the instructions given by the prescriber, pharmacist, or official leaflet.

Possible side effects

Like all medicines, EMEND can cause side effects. The leaflet information in the source content mentions the following:

  • Fatigue
  • Dizziness
  • Headache
  • Constipation
  • Loss of appetite

Not everyone gets side effects, and some may be mild. If anything feels severe, persistent, or unusual, speak to a healthcare professional.

Seek urgent medical help if signs of a serious allergic reaction occur, such as swelling, rash, or difficulty breathing.

Precautions and important safety points

Before using EMEND, it is important to tell a healthcare professional about any medical conditions, especially liver disease.

The source content also notes that EMEND may interact with other medicines, including:

  • Corticosteroids
  • 5-HT3 antagonists
  • Warfarin
  • Anticonvulsants

Because interactions can affect how medicines work, it is important to share a full list of prescribed medicines, over-the-counter products, and supplements with your pharmacist or doctor.

Pregnant or breastfeeding people should discuss use with a healthcare professional before taking EMEND.

Pregnancy and breastfeeding

The source content states that EMEND should not be used during pregnancy without medical advice, because safety has not been established.

If you are pregnant, think you may be pregnant, or are breastfeeding, ask a healthcare professional to review the leaflet information and your treatment plan.

What to check with your doctor or pharmacist

If you have been prescribed EMEND, it can help to confirm the following:

  • Which strength you should take and on which day
  • Whether it should be taken with other anti-sickness medicines
  • Whether any of your regular medicines may interact
  • What to do if you miss a dose
  • Whether your liver condition or pregnancy status changes the advice

These details should come from the official leaflet or your healthcare team.
