What is it and how is it used?

What is PREZISTA?

PREZISTA is an antiretroviral medicine used in the treatment of Human Immunodeficiency Virus (HIV) infection. It belongs to a group of medicines called protease inhibitors. PREZISTA works by reducing the amount of HIV in your body. This will improve your immune system and reduces the risk of developing illnesses linked to HIV infection.

What it is used for?

PREZISTA is used to treat adults and children of 6 years of age and above, and at least 20 kilogram body weight who are infected by HIV and who have already used other antiretroviral medicines.

PREZISTA must be taken in combination with a low dose of ritonavir and other anti-HIV medicines. Your doctor will discuss with you which combination of medicines is best for you.

What do you have to consider before using it?

PREZISTA must be taken in combination with a low dose of ritonavir and other antiretroviral medicines. It is therefore important that you read the package leaflet that is provided with these medicines. If you have any questions about your medicines, please ask your doctor or pharmacist.

Do not take PREZISTA

  • if you are allergic (hypersensitive) to darunavir, other ingredients of PREZISTA or to ritonavir.
  • if you have severe liver problems. Ask your doctor if you are unsure about the severity of your liver disease. Some additional tests might be necessary.

Do not combine PREZISTA with any of the following medicines

If you are taking any of these, ask your doctor about switching to another medicine.

Take special care with PREZISTA

PREZISTA is not a cure for HIV infection. PREZISTA does not reduce the risk of passing HIV to others through sexual contact or blood contamination. Therefore, you must continue to use appropriate precautions.

People taking PREZISTA may still develop infections or other illnesses associated with HIV infection. You must keep in regular contact with your doctor.

People taking PREZISTA may develop a skin rash. Infrequently a rash may become severe or potentially life-threatening. Please contact your doctor whenever you develop a rash.

In patients taking PREZISTA and raltegravir, rashes (generally mild or moderate) may occur more frequently than in patients taking either drug separately.

PREZISTA is not for use in children younger than 6 years of age or weighing less than 20 kilograms, as it has not been studied in this group.

PREZISTA has only been used in limited numbers of patients 65 years or older. If you belong to this age group, please discuss with your doctor if you can use PREZISTA.

Tell your doctor about your situation BEFORE and DURING your treatment Make sure that you check the following seven points and tell your doctor if any of these apply to you.

  • Tell your doctor if you have had problems with your liver before, including hepatitis B or C. Your doctor may evaluate how severe your liver disease is before deciding if you can take PREZISTA.
  • Tell your doctor if you have diabetes. PREZISTA might increase sugar levels in the blood.
  • Tell your doctor immediately if you notice any symptoms of infection (for example enlarged lymph nodes and fever). In some patients with advanced HIV infection and a history of opportunistic infection, signs and symptoms of inflammation from previous infections may occur soon after anti-HIV treatment is started. It is believed that these symptoms are due to an improvement in the body?s immune response, enabling the body to fight infections that may have been present with no obvious symptoms.
  • Tell your doctor if you notice changes in body fat. Redistribution, accumulation or loss of body fat may occur in patients receiving a combination of antiretroviral medicines.
  • Tell your doctor if you have haemophilia. PREZISTA, might increase the risk of bleeding.
  • Tell your doctor if you are allergic tosulphonamides (e.g. used to treat certain infections).
  • Tell your doctor if you notice any musculoskeletal problems. Some patients taking combination antiretroviral therapy may develop a bone disease called osteonecrosis (death of bone tissue caused by loss of blood supply to the bone). The length of combination antiretroviral therapy, corticosteroid use, alcohol consumption, severe immunosuppression, higher body mass index, among others, may be some of the many risk factors for developing this disease. Signs of osteonecrosis are joint stiffness, aches and pains (especially of the hip,

knee and shoulder) and difficulty in movement. If you notice any of these symptoms please inform your doctor.

Taking other medicines

PREZISTA might interact with other medicines. Please tell your doctor if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

There are some medicines that you must not combine with PREZISTA. These are mentioned above under the heading ?Do not combine PREZISTA with any of the following medicines:?

In most cases, PREZISTA can be combined with anti-HIV medicines belonging to another class [e.g. NRTIs (nucleoside reverse transcriptase inhibitors), NNRTIs (non-nucleoside reverse transcriptase inhibitors), CCR5 antagonists and FIs (fusion inhibitors)]. PREZISTA with ritonavir has not been tested with all PIs (protease inhibitors) and must not be used with some PIs. Therefore always tell your doctor if you take other anti-HIV medicines and follow your doctor?s instruction carefully on which medicines can be combined.

The effects of PREZISTA might be reduced if you take any of the following products. Tell your doctor if you take:

  • phenobarbital, phenytoin (to prevent seizures)
  • dexamethasone (steroid)
  • efavirenz (HIV infection).

The effects of other medicines might be influenced if you take PREZISTA. Tell your doctor if you take:

  • felodipine, nifedipine, nicardipine (for heart disease) as the therapeutic effect or unwanted side effects of these medicines may be increased.
  • warfarin (to reduce clotting of the blood) as their therapeutic effect or unwanted side effects may be altered; your doctor may have to check your blood.
  • estrogen-based hormonal contraceptives and hormonal replacement therapy. PREZISTA might reduce its effectiveness. When used for birth control, alternative methods of non-hormonal contraception are recommended.
  • pravastatin, atorvastatin, rosuvastatin (to lower cholesterol levels). The risk of muscle tissue disorder might be increased. Your doctor will evaluate which cholesterol lowering regimen is best for your specific situation.
  • clarithromycin (antibiotic)
  • cyclosporin, tacrolimus, sirolimus (to treat your immune system) as the therapeutic effect or unwanted side effects of these medicines might be increased. Your doctor might want to do some additional tests.
  • fluticasone, budesonide (to control asthma). Its use should only take place after medical evaluation and under close monitoring by your doctor for corticosteroid side effects.
  • buprenorphine/naloxone (medicines to treat opiate dependence)
  • salmeterol (medicine to treat asthma).

The dosage of other medicines might need to be changed since either their own or PREZISTA?s therapeutic effect or unwanted side effects may be influenced when combined.
Tell your doctor if you take:

  • digoxin (to treat certain heart disorders)
  • ketoconazole, itraconazole, clotrimazole (against fungal infections). Voriconazole should only be taken after medical evaluation.
  • rifabutin (against bacterial infections)
  • sildenafil, vardenafil, tadalafil (for erectile dysfunction or high blood pressure in the pulmonary circulation)
  • paroxetine, sertraline (to treat depression and anxiety)
  • methadone
  • sedative agents (e.g. midazolam administered by injection)
  • carbamazepine (to prevent seizures or to treat certain types of nerve pain)
  • colchicine (medicine to treat gout)
  • bosentan (medicine to treat high blood pressure int the pulmonary circulation).

Taking PREZISTA with food and drink

See section 3 ?How to take PREZISTA.?

Pregnancy and breast-feeding

Tell your doctor immediately if you are pregnant or if you are breast-feeding. Pregnant or breast-feeding mothers must not take PREZISTA unless specifically directed by the doctor. It is recommended that HIV infected women must not breast-feed their infants because of both the possibility of your baby becoming infected with HIV through your breast milk and because of the unknown effects of the medicine on your baby.

Driving and using machines

Do not operate machines or drive if you feel dizzy after taking PREZISTA.

How is it used?

Always use PREZISTA exactly as your doctor has told you. You must check with your doctor if you are not sure.

If you have any further questions on the use of this product, ask your doctor.

What are possible side effects?

Like all medicines, PREZISTA can cause side effects, although not everybody gets them. When treating HIV infection, it is not always easy to identify what side effects are caused by PREZISTA, which are caused by other medicines you are taking, or which are caused by the HIV infection itself.

The frequency of possible side effects listed below is defined using the following convention:

  • very common: affects more than 1 user in 10
  • common: affects 1 to 10 users in 100
  • uncommon: affects 1 to 10 users in 1,000
  • rare: affects 1 to 10 users in 10,000
  • very rare: affects less than 1 user in 10,000
  • not known: the frequency cannot be estimated from the available data.

  • changes in body shape due to fat redistribution. These may include loss of fat from legs, arms and face, increased fat in the abdomen (belly) and other internal organs, breast enlargement and fatty lumps on the back of the neck (buffalo hump). The cause and long-term health effects of these conditions are not known at this time.
