1. What Pentacarinat is and what it is used for

The name of your medicine is Pentacarinat 300mg powder for solution for injection/infusion (called Pentacarinat powder in this leaflet). Pentacarinat powder contains a medicine called pentamidine isetionate.

Pentacarinat powder can be used to:

  • Treat or help prevent a lung infection called ‘Pneumocystis carinii Pneumonia (PCP). It often happens in people with the HIV virus.
  • Treat diseases of the skin or organs caused by parasites (Leishmania and Trypanosoma gambiense).

2. Before you have Pentacarinat Powder
Do not have this medicine if:
  • You are allergic (hypersensitive) to pentamidine isetionate or any of the ingredients of this medicine (see Section 6: Further information).

Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of the lips, face, throat and tongue.

Do not have this medicine if the above applies to you.

Take special care with Pentacarinat powder

Check with your doctor or your pharmacist before having this medicine if:

  • You have liver or kidney problems.
  • You have high or low blood pressure.
  • You have a slow heartbeat (bradycardia), an uneven heartbeat or any other heart problems.
  • You have a high or low blood sugar level.
  • You have a low white blood cell count - signs include an unexplained infection or fever.
  • You have anaemia (look pale or feel tired).
  • You have unusual bruising or your blood takes a long time to clot.
  • You have asthma, other breathing problems, or had a collapsed lung (pneumothorax) in the past.
  • You smoke.
  • You have unusual salt levels in your blood, especially if you have low levels of potassium (‘hypokalaemia’) or magnesium (‘hypomagnesaemia’).
    Blood tests will have shown this.

If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before having Pentacarinat 300mg.

Taking other medicines

If you have to go to a doctor, dentist or hospital for any reason, tell them that you are taking Pentacarinat powder. Also tell your doctor or pharmacist if you are taking or have recently taken any other medicine. This includes medicines you buy without a prescription, including herbal medicines. This is because Pentacarinat powder and some medicines can affect the way each other work.

In particular, tell your doctor if you are taking any of the following:

  • Medicines for mood or thought problems called ‘phenothiazines’ (such as chlorpromazine and pericyazine).
  • Medicines for depression called ‘tricyclic antidepressants’ (such as amitriptyline).
  • Anti-histamines called terfenadine and astemizole - used for allergies.
  • Antibiotics such as erythromycin or quinolones (includes ciprofloxacin).
  • Halofantrine - used for malaria.
  • Foscarnet - used for viral infections.

These medicines may cause an uneven heartbeat (seen on your ECG)called ‘QT prolongation’. Pentacarinat 300mg can increase the chance of this happening.


Before you are given Pentacarinat powder, your doctor will check your blood pressure, heart and blood.

Pregnancy and breast-feeding

Talk to your doctor before taking this medicine if:

  • You are pregnant, plan to get pregnant, or think you may be pregnant.
    Miscarriage has been reported during the first three months of pregnancy.
  • You are breast-feeding or planning to breast-feed.

Ask your doctor or pharmacist for advice before taking any medicine if you are pregnant or breast-feeding.
