STOCRIN 30 mg/ml oral solution

STOCRIN belongs to a class of antiretroviral medicines called non-nucleoside reverse transcriptase inhibitors (NNRTIs). It is an antiretroviral medicine that fights human immunodeficiency virus (HIV) infection by reducing the amount of the virus in blood.

Your doctor has prescribed STOCRIN for you because you have HIV infection. STOCRIN taken in combination with other antiretroviral medicines reduces the amount of the virus in the blood.

Do not take STOCRIN

• if you are allergic (hypersensitive) to efavirenz or any of the other ingredients of STOCRIN listed at the end of this leaflet. Contact your doctor or pharmacist for advice.
• if you have severe liver disease
• if you are currently taking any of the following medicines:
• astemizole or terfenadine (used to treat allergy symptoms)
• bepridil (used to treat heart disease)
• cisapride (used to treat heartburn)
• ergot alkaloids (for example, ergotamine, dihydroergotamine, ergonovine, and methylergonovine) (used to treat migraine and cluster headaches)
• midazolam or triazolam (used to help you sleep)
• pimozide (used to treat certain mental conditions)
• St. John's wort ( Hypericum perforatum) (a herbal remedy used for depression and anxiety)

If you are taking any of these medicines, tell your doctor immediately. Taking these medicines with STOCRIN could create the potential for serious and/or life-threatening side-effects or stop STOCRIN from working properly.

Take special care with STOCRIN

• STOCRIN must be taken with other medicines that act against the HIV virus. If STOCRIN is started because your current treatment has not prevented the virus from multiplying, another medicine you have not taken before must be started at the same time.
• You can still pass on HIV when taking this medicine, so it is important to take precautions to avoid infecting other people through sexual contact or blood transfer. This medicine is not a cure for HIV infection and you may continue to develop infections or other illnesses associated with HIV disease.
• You must remain under the care of your doctor while taking STOCRIN.
• Tell your doctor:
• if you have a history of mental illness, including depression, or of substance or alcohol abuse. Tell your doctor immediately if you feel depressed, have suicidal thoughts or have strange thoughts (see section 4, Possible side effects).
• if you have a history of convulsions(fits or seizures) or if you are being treated with anticonvulsant therapy such as carbamazepine, phenobarbital and phenytoin. If you are taking any of these medicines, your doctor may need to check the level of anticonvulsant medicine in your blood to ensure that it is not affected while taking STOCRIN. Your doctor may give you a different anticonvulsant.
• if you have a history of liver disease, including active chronic hepatitis. Patients with chronic hepatitis B or C and treated with combination antiretroviral agents have a higher risk for severe and potentially life-threatening liver problems. Your doctor may conduct blood tests in order to check how well your liver is working or may switch you to another medicine. If you have severe liver disease, do not take STOCRIN (see Section 2, Do not take STOCRIN).
• Once you start taking STOCRIN, look out for:
• signs of dizziness, difficulty sleeping, drowsiness, difficulty concentrating or abnormal dreaming. These side effects may start in the first 1 or 2 days of treatment and usually go away after the first 2 to 4 weeks.
• any signs of skin rash. If you see any signs of a severe rash with blistering or fever, stop taking STOCRIN and tell your doctor at once. If you had a rash while taking another NNRTI, you may be at a higher risk of getting a rash with STOCRIN.
• any signs of inflammation or infection. In some patients with advanced HIV infection (AIDS) 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. If you notice any symptoms of infection, please tell your doctor immediately.
• changes in body fat. Redistribution, accumulation or loss of body fat may occur in patients receiving combination antiretroviral therapy. Tell your doctor if you notice changes in your body fat.
• 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.

Use in children
STOCRIN oral solution can be taken by children 3 years of age and older (see How to take STOCRIN).

Taking other medicines
You must not take STOCRIN with certain medicines. These are listed under Do not take STOCRIN, at the start of Section 2. They include some common medicines and a herbal remedy (St. John?s wort) which can cause serious interactions.

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription and herbal remedies.

STOCRIN may interact with other medicines. As a result, the amounts of STOCRIN or other medicines in your blood may be affected. This may stop the medicines from working properly, or may make any side effects worse. In some cases, your doctor may need to adjust your dose or check your blood levels. It is important to tell your doctor if you are taking any of the following:

Other medicines used for HIV infection:

• protease inhibitors: darunavir, indinavir, lopinavir/ritonavir, ritonavir, ritonavir boosted atazanavir, saquinavir or fosamprenavir/saquinavir. Your doctor may consider giving you an alternative medicine or changing the dose of the protease inhibitors.
• maraviroc
• a combination medicine which contains efavirenz, emtricitabine and tenofovir, which is currently known as ATRIPLA. STOCRIN should not be taken with ATRIPLA since it contains efavirenz, the active ingredient of STOCRIN.

Medicines used to treat bacterial infections, including tuberculosis and AIDS-related mycobacterium avium complex: clarithromycin, rifabutin, rifampicin. Your doctor may consider changing your dose or giving you an alternative antibiotic. In addition, your doctor may prescribe a higher dose of STOCRIN.

Medicines used to treat fungal infections (antifungals):

• voriconazole. STOCRIN may reduce the amount of voriconazole in your blood and voriconazole may increase the amount of STOCRIN in your blood. If you take these two medicines together, the dose of voriconazole must be increased and the dose of efavirenz must be reduced. You must check with your doctor first.
• itraconazole. STOCRIN may reduce the amount of itraconazole in your blood.
• posaconazole. STOCRIN may reduce the amount of posaconazole in your blood.

Medicines used to treat convulsions/seizures (anticonvulsants): carbamazepine, phenytoin, phenobarbital. STOCRIN can reduce or increase the amount of anticonvulsant in your blood. Carbamazepine may make STOCRIN less likely to work. Your doctor may need to consider giving you a different anticonvulsant.

Medicines used to lower blood fats (also called statins): atorvastatin, pravastatin, simvastatin. STOCRIN can reduce the amount of statins in your blood. Your doctor will check your cholesterol levels and will consider changing the dose of your statin, if needed.

Methadone (a medicine used to treat opiate addiction): your doctor may need to change your dose of methadone.

Sertraline (a medicine used to treat depression): your doctor may need to change your dose of sertraline.

Diltiazem or similar medicines (called calcium channel blockers): when you start taking STOCRIN, your doctor may need to adjust your dose of the calcium channel blocker.

Immunosuppressants such as cyclosporine, sirolimus, or tacrolimus (medicines used to prevent organ transplant rejection): when you start or stop taking STOCRIN, your doctor will closely monitor your plasma levels of the immunosuppressant and may need to adjust its dose.

Hormonal contraceptive, such as birth control pills, an injected contraceptive (for example, Depo-Provera), or a contraceptive implant (for example, Implanon): you must also use a reliable barrier method of contraception (see Pregnancy and breast-feeding). STOCRIN may make hormonal contraceptives less likely to work. Pregnancies have occurred in women taking STOCRIN while using a contraceptive implant, although it has not been established that the STOCRIN therapy caused the contraceptive to fail.

Warfarin (amedicine used to reduce clotting of the blood): your doctor may need to adjust your dose of warfarin.

Pregnancy and breast-feeding
Women should not get pregnant during treatment with STOCRIN and for 12 weeks thereafter. Your doctor may require you to take a pregnancy test to ensure you are not pregnant before starting treatment with STOCRIN.

If you could get pregnant while receiving STOCRIN, you need to use a reliable form of barrier contraception (for example, a condom) with other methods of contraception including oral (pill) or other hormonal contraceptives (for example, implants, injection). Efavirenz may remain in your blood for a time after therapy is stopped. Therefore, you should continue to use contraceptive measures, as above, for 12 weeks after you stop taking STOCRIN.

Tell your doctor immediately if you are pregnant or intend to become pregnant. If you are pregnant, you should take STOCRIN only if you and your doctor decide it is clearly needed. Ask your doctor or pharmacist for advice before taking any medicine.

Serious birth defects have been seen in unborn animals and in the babies of women treated with efavirenz during pregnancy. If you have taken STOCRIN during your pregnancy, your doctor may request regular blood tests and other diagnostic tests to monitor the development of your child.

You should not breast feed your baby if you are taking STOCRIN.

Driving and using machines
STOCRIN may cause dizziness,impaired concentration, and drowsiness.
If you are affected, do not drive and do not use any tools or machines.

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

• STOCRIN oral solution may be taken with or without food.
• The dose for adults is 24 ml once daily.
• The dose for STOCRIN may need to be increased or decreased if you are also taking certain medicines (see Taking other medicines).

The dose of STOCRIN oral solution in mg is not the same as for STOCRIN hard capsules or film-coated tablets. Your doctor will give you instructions for proper dose.

• STOCRIN must be taken every day.
• STOCRIN should never be used alone to treat HIV. STOCRIN must always be taken in combination with other anti-HIV medicines.

The dose of STOCRIN oral solution must be measured using the oral syringe supplied in the carton. On first use, the bottle adapter must be fitted into the neck of the 0lm281614121018bottle. To do this, remove the child-resistant cap and the foil seal. 6420The bottle adapter, which is already fixed to the nozzle of the syringe, can then be fitted into the neck of the bottle and pressed firmly down. Separate the syringe from the adapter. The adapter should now fit 86420closely to the neck so that the cap can be replaced without removing it. With the bottle upright, fit the tip of the syringe into the bottle adapter. 86420 Turn the bottle upside down with the syringe still in place. Hold the bottle and the syringe firmly in one hand and with the other hand pull back the plunger slightly beyond the mark for the dose required. If air bubbles appear in the syringe, keep the bottle upside down and slowly 0push in the plunger and pull it back again. Repeat until there are no 2468bubbles in the syringe. 1012 To measure the dose accurately, keep the bottle upside down and push the plunger in slowly until the top of the black ring the edge nearest the syringe tip lines up with the dose. Turn the bottle the right way 1up and remove the syringe. Wipe the adapter and replace the cap 23L45 m67L8910 m11tightly over it. 12L131415 m1617L181920 m Before giving the dose of the oral solution make sure that the patient is sitting or standing upright. Put the tip of the syringe just inside the mouth, pointing it towards the cheek. Press the plunger slowly to 2468allow time for the medicine to be swallowed. Rapid squirting into the 10121416l18 m20mouth may cause choking.

After use, soak the syringe in warm soapy water for at least a minute. Draw the warm soapy water into the syringe until full and then empty completely. Repeat at least three times. Remove the plunger rod from the barrel and thoroughly rinse both parts with warm running water. If parts of the syringe are not clean, repeat the cleaning instructions. Allow the parts to dry completely prior to reassembly. Do not put the syringe in a dishwasher.

Use in children

• The dose for children weighing 40 kg or more is 24 ml once daily.
• The dose for children weighing less than 40 kg is calculated by body weight and is taken once daily as shown below:

Body Weight kg 3 - 5 years STOCRIN oral solution 30 mgml Dose ml 5 years or more 13 to 15 12 9 15 to 20 13 10 20 to 25 15 12 25 to 32.5 17 15 32.5 to 40 - 17 40 - 24

If you take more STOCRIN than you should

If you take too much STOCRIN contact your doctor or nearest emergency department for advice. Keep the medicine container with you so that you can easily describe what you have taken.

If you forget to take STOCRIN

Try not to miss a dose. If you do miss a dose, take the next dose as soon as possible, but do not take a double dose to make up for a forgotten dose. If you need help in planning the best times to take your medicine, ask your doctor or pharmacist.

If you stop taking STOCRIN
When your STOCRIN supply starts to run low, get more from your doctor or pharmacist. This is very important because the amount of virus may start to increase if the medicine is stopped for even a short time. The virus may then become harder to treat.

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

Like all medicines, STOCRIN can cause side effects, although not everybody gets them. When treating HIV infection, it is not always possible to tell whether some of the unwanted effects are caused by STOCRIN or by other medicines that you are taking at the same time, or by the HIV disease itself.

The most notable unwanted effects reported with STOCRIN in combination with other anti-HIV medicines are skin rash and nervous system symptoms.

You should consult your doctor if you have a rash, since some rashes may be serious; however, most cases of rash disappear without any change to your treatment with STOCRIN. Rash was more common in children than in adults treated with STOCRIN.

The nervous system symptoms tend to occur when treatment is first started, but generally decrease in the first few weeks. In one study, nervous system symptoms often occurred during the first 1-3 hours after taking a dose. If you are affected your doctor may suggest that you take STOCRIN at bedtime.

Some patients have more serious symptoms that may affect mood or the ability to think clearly. Some patients have actually committed suicide. These problems tend to occur more often in those who have a history of mental illness. Always notify your doctor immediately if you have these symptoms or any side effects while taking STOCRIN.

Diarrhoea occurred in children who took STOCRIN oral solution and nelfinavir in combination with other antiretroviral medicines.

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

Very common Common affects more than 1 user in 10 affects 1 to 10 users in 100 Uncommon Rare affects 1 to 10 users in 1,000 affects 1 to 10 users in 10,000

Combination antiretroviral therapy may change your body shape by changing the way body fat is distributed. You may lose fat from your legs, arms and face, gain fat in the abdomen (tummy) and other internal organs, get larger breasts or fatty lumps on the back of the neck (?buffalo hump?). The cause and long-term health effects of these conditions are not yet known.

Combination antiretroviral therapy may also cause raised lactic acid and sugar in the blood, increased fat levels in the blood (hyperlipaemia) and resistance to insulin. Your doctor will test for these changes.

If any of the side effects get serious, or you notice any side effects not listed in this leaflet, please tell your doctor or pharmacist.
