FAQ

Indinavir is a prescription-only medicine when obtained from local pharmacies in the United Kingdom. Our store policy allows you to order it without a prescription and have it sent by mail. Treatment should still be prescribed and monitored by an HIV specialist.

Do not increase the dose, extend treatment or stop taking indinavir independently. Indinavir must be used with other antiretroviral medicines, and treatment response is assessed with HIV viral-load and other clinical tests rather than symptoms alone. Contact the HIV treatment team promptly for reassessment.

The exact manufacturer is not confirmed in advance and may vary between supplies. Check the manufacturer's name on the received package label, along with the active ingredient, 400 mg strength, dosage form, batch number and expiry date.

Store the capsules at 15°C to 30°C in their original, tightly closed container. Keep the desiccant in the container to protect the capsules from moisture.

Indinavir capsules are taken by mouth as part of combination HIV treatment. A standard adult regimen has been 800 mg every 8 hours, which is two 400 mg capsules per dose, but the regimen must be selected by the treating HIV specialist. Take doses on an empty stomach, at least 1 hour before or 2 hours after food, with a full glass of water; adequate daily fluid intake, usually at least 1.5 L, helps reduce the risk of kidney stones.

Indinavir is an HIV protease inhibitor used to treat HIV-1 infection. It is used with other antiretroviral medicines, not as treatment on its own, to help suppress viral replication.

What is Indinavir?

Indinavir is an antiretroviral medicine in the protease inhibitor class. In the UK, it is prescribed to treat human immunodeficiency virus (HIV) infection and is usually taken with other antiviral medicines. Indinavir helps reduce viral replication in the body, but it does not cure HIV. It will not work for influenza (flu), colds or other non-HIV viral infections.

Ask your doctor, pharmacist or other healthcare professional in the United Kingdom for more information about how this medicine may affect you.

What important information should I know about Indinavir?

Grapefruit and grapefruit juice can reduce indinavir levels. Avoid grapefruit products while taking indinavir unless your healthcare provider tells you otherwise.

Do not stop taking indinavir or change your dose without medical advice. Stopping treatment can make it less effective and may contribute to viral resistance.

Indinavir may cause dizziness or affect coordination. Take care when driving, using machinery, climbing or doing anything hazardous until you know how the medicine affects you.

Alcohol may increase the risk of side effects such as flushing and a rapid heart rate. Take care with alcohol while taking indinavir.

Always tell a doctor before giving indinavir to a child.

What should I tell my doctor before I take this drug?

Your healthcare provider should know if you have:

  • Heart disorders (including rhythm problems)
  • Liver disease or kidney disease
  • Anaemia or other blood disorders
  • An allergy to indinavir or similar medicines, foods, dyes or preservatives
  • Stomach or bowel problems (including colitis)
  • Haemophilia
  • Diabetes
  • Pregnancy, breastfeeding, or plans to become pregnant

How to take Indinavir

Indinavir comes as capsules to take by mouth.

The usual adult dose is 800 mg taken every 8 hours (3 times daily).

Swallow the capsules whole. Do not open, crush, chew or break them.

Your dose may vary depending on your treatment plan. Follow your doctor's instructions exactly.

What should you do if you miss a dose?

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 regular schedule. Do not take a double dose to make up for a missed dose.

What should you do in case of overdose?

Get medical help straight away if you think you have taken too much. Symptoms of overdose may include pain in your side, vomiting, diarrhoea, nausea or blood in the urine.

I live in Newry, Northern Ireland. Can I confirm that indinavir can be delivered to my address before I pay?

Asked by James, Leeds, United Kingdom

I have type 2 diabetes and monitor my glucose at home. Is there anything specific I should know before taking indinavir?

Answered by Support team
Medical reviewed by Donna Brettler

Protease inhibitors including indinavir can cause raised blood glucose, new-onset diabetes or worsening of existing diabetes. Your HIV clinician should review your glucose control and diabetes medicines, and you should seek advice promptly for persistent high readings or symptoms such as unusual thirst or frequent urination.
