Intelence (Etravirine)

What Intelence is and what it is used for

Intelence is a medicine used for the treatment of Human Immunodeficiency Virus (HIV) infection. It belongs to a group of anti-HIV medicines called non-nucleoside reverse transcriptase inhibitors (NNRTIs). Intelence 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.

Intelence is used in combination with other anti-HIV medicines to treat adults who are infected by HIV and who have used other anti-HIV medicines before.

Your doctor will discuss with you which combination of medicines is best for you.

Before you take Intelence

Do not take Intelence

  • if you are allergic (hypersensitive) to etravirine or any of the other ingredients of Intelence. These other ingredients are listed in section 6.

Take special care with Intelence

Intelence is not a cure for HIV infection. It is part of a treatment reducing the amount of virus in the blood. Intelence does not reduce the risk of passing HIV to others through sexual contact or contamination with blood. Therefore, you must continue to use appropriate precautions (a condom or other barrier method) to lower the chance of sexual contact with any body fluids such as semen, vaginal secretions or blood.

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

Intelence is not for use in children or adolescents, because it has not been sufficiently studied in patients under 18 years of age.

Intelence has only been used in a limited number of patients of 65 years or older. If you belong to this age group, please discuss the use of Intelence with your doctor.

Tell your doctor about your situation

Make sure that you check the following points and tell your doctor if any of these apply to you.

Tell your doctor if you develop a rash. If a rash occurs, it usually appears soon after anti-HIV treatment with Intelence is started and often disappears within 1 to 2 weeks, even with continued use of the medicine. Occasionally during Intelence treatment, you can experience hypersensitivity reaction (allergic reaction including rash and fever but also swelling of the face, tongue or throat, difficulty in breathing or swallowing) which could be potentially life-threatening. Please contact your doctor immediately ifyou get a hypersensitivity reaction. Your doctor will advise you how to deal with your symptoms and whether Intelence must be stopped. Ifyou have stopped treatment due to a hypersensitivity reaction, you should not re-start therapy with Intelence.

Tell your doctor ifyou have or have had problems with your liver, including hepatitis B and/or C. Your doctor may evaluate how severe your liver disease is before deciding ifyou can take Intelence.

Tell your doctor ifyou notice changes in body shape or fat. A gain, loss or redistribution of body fat may occur ifyou take a combination of anti-HIV medicines.

Tell your doctor immediately ifyou notice any symptoms of infections. 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.

Taking other medicines

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

In most cases, Intelence can be combined with anti-HIV medicines belonging to another class. However some combinations are not recommended. In other cases, increased monitoring and/or a change in the dose of the medicine may be needed. Therefore always tell your doctor which other anti-HIV medicines you take. Furthermore, it is important that you carefully read the package leaflets that are provided with these medicines. Follow your doctor’s instruction carefully on which medicines can be combined.

It is not recommended to combine Intelence with any of the following medicines:

  • tipranavir/ritonavir (anti-HIV medicine)
  • carbamazepine, phenobarbital, phenytoin (medicines to prevent seizures)
  • rifampicin, because it is contraindicated with boosted protease inhibitors, and rifapentine (medicines to treat some infections such as tuberculosis)
  • products that contain St John’s wort (Hypericumperforatum) (a herbal product used for depression).

If you are taking any of these, ask your doctor for advice.

The effects of Intelence or other medicines might be influenced ifyou take Intelence together with any of the following medicines. Tell your doctor ifyou take:

  • amiodarone, bepridil, digoxin, disopyramide, flecainide, lidocaine, mexiletine, propafenone and quinidine (medicines to treat certain heart disorders, e.g., abnormal heart beat)
  • warfarin (a medicine used to reduce clotting of the blood). Your doctor will have to check your blood
  • fluconazole, itraconazole, ketoconazole, posaconazole, voriconazole (medicines to treat fungal infections)
  • clarithromycin, rifabutin (antibiotics)
  • diazepam (medicines to treat trouble with sleeping and/or anxiety)
  • dexamethasone (a corticosteroid used in a variety of conditions such as inflammation and allergic reactions)
  • atorvastatin, fluvastatin, lovastatin, rosuvastatin, simvastatin (cholesterol-lowering medicines)
  • cyclosporine, sirolimus, tacrolimus (immunosuppressants)
  • sildenafil, vardenafil, tadalafil (medicines to treat erectile dysfunction).

Taking Intelence with food and drink

It is important that you take Intelence following a meal. If you take it on an empty stomach, only half the amount of Intelence is absorbed. For further information see section

How to take Intelence

Pregnancy and breast-feeding

Tell your doctor immediately if you are pregnant. Pregnant women should not take Intelence unless specifically directed by the doctor.

HIV infected mothers must not breast-feed, as there is a possibility of infecting the baby with HIV.

Driving and using machines

No studies on the effects of Intelence on the ability to drive and use machines have been performed. However, do not drive or operate machines if you feel sleepy or dizzy after taking your medicines.

Important information about some of the ingredients of Intelence

Intelence tablets contain lactose. If you have been told by your doctor that you have an intolerance to some sugars (lactose), contact your doctor before taking this medicine.

Bone 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.

Always take Intelence exactly as your doctor has told you. You should check with your doctor if you are not sure.

Instructions for proper use

The usual dose of Intelence is two tablets twice a day.

  • In the morning, take two 100 milligram Intelence tablets, following a meal.
  • In the evening, take two 100 milligram Intelence tablets, following a meal.

It is important that you take Intelence following a meal. If you take Intelence on an empty stomach, only half the amount of Intelence is absorbed. Swallow the tablets whole with a glass of water. Do not chew the tablets. If you are unable to swallow the Intelence tablets whole, you may place the tablets in a glass of water. Stir well until the water looks milky, then drink it immediately.

Rinse the glass with water several times, and completely swallow the rinse each time to make sure you take the entire dose.

Push the plastic screw cap down while turning it counter clockwise.

If you take more Intelence than you should

Contact your doctor or pharmacist immediately.

If you forget to take Intelence

If you notice within 6 hours of the time you usually take Intelence, you must take the tablets as soon as possible. Always take the tablets following a meal. Then take the next dose as usual. If you notice after 6 hours, then skip the intake and take the next doses as usual. Do not take a double dose to make up for a forgotten dose.

Do not stop using Intelence without talking to your doctor first

HIV therapy may increase your sense of well-being. Even if you feel better, do not stop taking Intelence or your other anti-HIV medicines. Doing so could increase the risk of the virus developing resistance. Talk to your doctor first.

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