1. what darunavir is and what it is used for

What is Darunavir?

Darunavir contains the active substance darunavir. Darunavir is an

antiretroviral medicine used in the treatment of Human Immunodeficiency Virus (HIV) infection. It belongs to a group of medicines called protease inhibitors. Darunavir 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?

Darunavir is used to treat adults and children of 3 years of age and above, and at least 15 kilogram body weight who are infected by HIV and who have already used other antiretroviral medicines.

Darunavir 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.

2. what you need to know before you take darunavir

Do not take Darunavir

• – if you are allergic to darunavir or any of the other ingredients of this medicine (listed in section 6) or to ritonavir.

Warnings and precautions

Talk to your doctor, pharmacist or nurse before taking Darunavir.

Darunavir is not a cure for HIV infection. You can still pass on HIV when taking this medicine, although the risk is lowered by effective antiretroviral therapy. Discuss with your physician the precautions needed to avoid infecting other people.

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

People taking Darunavir 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 Darunavir and raltegravir (for HIV infection), rashes (generally mild or moderate) may occur more frequently than in patients taking either medicine separately.

Tell your doctor about your situation BEFORE and DURING your treatment

Make sure that you check the following 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 infection. Your doctor may evaluate how severe your liver disease is before deciding if you can take Darunavir.

• – Tell your doctor if you have diabetes. Darunavir 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.

– In addition to the opportunistic infections, autoimmune disorders (a condition that occurs when the immune system attacks healthy body tissue) may also occur after you start taking medicines for the treatment of your HIV infection. Autoimmune disorders may occur many months after the start of treatment. If you notice any symptoms of infection or other symptoms such as muscle weakness, weakness beginning in the hands and feet and moving up towards the trunk of the body, palpitations, tremor or hyperactivity, please inform your doctor immediately to seek necessary treatment.

• – Tell your doctor if you have haemophilia. Darunavir might increase the risk of bleeding.

• – Tell your doctor if you are allergic to sulphonamides (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.

Elderly

Darunavir 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 Darunavir.

Children

Darunavir is not for use in children younger than 3 years of age or weighing less than 15 kilograms.

Other medicines and Darunavir

Tell your doctor or pharmacist if you are taking or have recently taken any other medicines.

There are some medicines that you must not combine with Darunavir.

These are mentioned above under the heading ‚Do not combine Darunavir with any of the following medicines:‘

In most cases, Darunavir 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)]. Darunavir with ritonavir has not been tested with all Pis (protease inhibitors) and must not be used with other HIV PIs. In some cases dosage of other medicines might need to be changed. 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 Darunavir might be reduced if you take any of the following products. Tell your doctor if you take:

• - Phenobarbital, phenytoin (to prevent seizures)

• - Dexamethasone (corticosteroid)

• - Efavirenz (HIV infection)

• - Boceprevir (hepatitis C infection)

• - Rifapentine, rifabutin (medicines to treat some infections such as tuberculosis)

• - Saquinavir (HIV infection).

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

• - Amlodipine, diltiazem, disopyramide, carvedilol, felodipine, flecainide, lidocaine, metoprolol, mexiletine, nifedipine, nicardipine , propafenone , timolol, verapamil (for heart disease) as the therapeutic effect or side effects of these medicines may be increased.

• - Apixaban, edoxaban, rivaroxaban, warfarin (to reduce clotting of the blood) as their therapeutic effect or side effects may be altered; your doctor may have to check your blood.

• – Oestrogen-based hormonal contraceptives and hormonal replacement therapy. Darunavir might reduce its effectiveness. When used for birth control, alternative methods of non-hormonal contraception are recommended.

• - Ethinylestradi­ol/drospireno­ne. Darunavir might increase the risk for

elevated potassium levels by drospirenone.

• - Atorvastatin, pravastatin, rosuvastatin (to lower cholesterol levels).

The risk of muscle damage might be increased. Your doctor will evaluate which cholesterol lowering regimen is best for your specific situation.

• - Clarithromycin (antibiotic)

• - Ciclosporin, everolimus, tacrolimus, sirolimus (for dampening down

your immune system) as the therapeutic effect or side effects

of these medicines might be increased. Your doctor might want to do some additional tests.

– Corticosteroids including betamethasone, budesonide, fluticasone, mometasone, prednisone, triamcinolone. These medicines are used to treat allergies, asthma, inflammatory bowel diseases, inflammatory conditions of the eyes, joints and muscles and other inflammatory conditions. If alternatives cannot be used, 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 opioid dependence)

• - Salmeterol (medicine to treat asthma)

• - Artemether/lu­mefantrine (a combination medicine to treat malaria)

• - Dasatinib, everolimus, irinotecan, nilotinib, vinblastine, vincristine (to treat cancer)

• - Sildenafil, tadalafil, vardenafil (for erectile dysfunction or to treat a heart and lung disorder called pulmonary arterial hypertension)

• - Glecaprevir/pi­brentasvir , simeprevir (to treat hepatitis C infection)

• - Fentanyl, oxycodone, tramadol (to treat pain).

• - Fesoterodine, solifenacin (to treat urologic disorders).

The dosage of other medicines might need to be changed since either their own or Darunavir therapeutic effect or side effects may be influenced when combined.

Tell your doctor if you take:

• - Alfentanil (injectable strong and short-acting painkiller that is used for surgical procedures)

• - Digoxin (to treat certain heart disorders)

• - Clarithromycin (antibiotic)

• - Itraconazole, isavuconazole, fluconazole, posaconazole, clotrimazole

(to treat fungal infections). Voriconazole should only be taken after medical evaluation.

4. Possible side effects

During HIV therapy there may be an increase in weight and in levels of blood lipids and glucose. This is partly linked to restored health and life style, and in the case of blood lipids sometimes to the HIV medicines themselves. Your doctor will test for these changes.

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Tell your doctor if you develop any of the following side effects.

Liver problems that may occasionally be severe have been reported.

Your doctor should do blood tests before you start Darunavir. If you have chronic hepatitis B or C infection, your doctor should check your blood tests more often because you have an increased chance of developing liver problems. Talk to your doctor about the signs and symptoms of liver problems. These may include yellowing of your skin or whites of your eyes, dark (tea coloured) urine, pale coloured stools (bowel movements), nausea, vomiting, loss of appetite, or pain, aching, or pain and discomfort on your right side below your ribs.

Skin rash (more often when used in combination with raltegravir), itching.
