Invirase is an antiviral agent. It is a member of a class of medicines called protease inhibitors. It is for the treatment of infection with the human immunodeficiency virus (HIV).
Invirase is used by HIV-infected individuals over 16 years of age. Invirase is prescribed for use in combination with ritonavir and other antiretroviral medicines.
- if you are allergic (hypersensitive) to saquinavir, ritonavir or any of the other ingredients (see section ?Important information about an ingredient of Invirase? and section ?What Invirase contains?).
- if you were born with or have
You should know that Invirase/ritonavir is not a cure for HIV infection and that you may continue to develop infections or other illnesses associated with HIV disease. You should, therefore, remain under the care of your doctor while taking Invirase/ritonavir.
Treatment with Invirase/ritonavir has not been shown to reduce the risk of transmission of HIV to others through sexual contacts or contamination with blood. Therefore, you must continue to take appropriate precautions to avoid giving the virus to others.
At present, there is only limited information on the use of Invirase/ritonavir in children under the age of 16 years and in adults over 60 years.
Invirase can change your heart?s ECG, especially if you are female or elderly. If you are taking any medicine that decreases your blood potassium levels talk to your doctor before taking Invirase. Contact your doctor immediately, if you experience palpitations or an irregular heartbeat during treatment. He/she may wish to perform an ECG to measure your heart rhythm.
Consult your doctor if you have a history of kidney disease.
Please speak with your doctor if you have a history of liver disease. Patients with chronic hepatitis B or C and treated with antiretroviral agents are at increased risk for severe and potentially fatal liver adverse events and may require blood tests for control of liver function.
There are certain conditions, which you may have, or have had, which require special care before or while taking Invirase/ritonavir. Therefore, before using this medicine, you should have told your doctor if you suffer from diabetes mellitus, diarrhoea, or if you have allergies (see section 4) or if you have an intolerance to some sugars (see section ?Important information about an ingredient of Invirase?).
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 inform your doctor immediately (see section 4).
Redistribution, accumulation or loss of body fat may occur in patients receiving combination antiretroviral therapy. Contact your doctor if you notice changes in body fat (see section 4).
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.
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.
Invirase/ritonavir may be taken with a number of other medications that are commonly used in HIV infection.
There are some medications that must not be taken with Invirase/ritonavir (see section "Do not take
Invirase") or that require dosage reduction of that medicine or Invirase or ritonavir. Ask your doctor or pharmacist for more information about taking Invirase/ritonavir with other medicines.
Medicines that can interact with saquinavir andor ritonavir include other HIV antiviral agents e.g. nelfinavir, indinavir, nevirapine, delavirdine, efavirenz, some medicines affecting the immune system e.g. ciclosporin, sirolimus rapamycin, tacrolimus, various steroids e.g. dexamethasone, ethinyl estradiol, fluticasone, certain heart medicines e.g. calcium channel blockers, quinidine, digoxin, medicines used to lower blood cholesterol e.g. statins, antifungals ketoconazole, itraconazole, anticonvulsants e.g. phenobarbital, phenytoin, carbamazepine, sedative agents e.g. midazolam administered by injection, certain antibiotics e.g. quinupristindalfopristin, rifabutin, medicines to treat depression e.g. nefazodone, tricyclic antidepressants, medicines for anticoagulation warfarin, herbal preparations containing St. Johns wort or garlic capsules, some medicines that treat diseases related to the acid in the stomach e.g. omeprazole or other proton pump inhibitors
Therefore you should not take Invirase/ritonavir with other medicines without your doctor?s consent.
If you are taking an oral contraceptive to prevent pregnancy, you should use an additional or different type of contraception since ritonavir may reduce the effectiveness of oral contraceptives.
Taking Invirase with food and drinkInvirase must be taken together with ritonavir and with or after food.
Ask your doctor or pharmacist for advice before taking any medicine. Inform your doctor if you are pregnant or planning to become pregnant. This medicine should be taken during pregnancy only after consultation with your doctor.

Always take Invirase/ritonavir exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure. Invirase is provided as 200 mg capsules. Your doctor will prescribe Invirase in combination with Norvir (ritonavir) and other HIV medicines. The dosage of Invirase is five 200 mg capsules with one 100 mg capsule of Norvir (ritonavir) two times daily. If you have not received other HIV medicines before and you are taking Invirase for the first time, you should take a reduced dosage of Invirase of one 500 mg film coated tablet with one 100 mg capsule of Norvir (ritonavir) two times daily for the first week (see Package Leaflet for INVIRASE 500 mg film-coated tablets). After the first week you should continue with the standard Invirase dosage of five 200 mg capsules with one 100 mg capsule of Norvir (ritonavir) two times daily. Patients who switch immediately without pause between the treatment regimens from another protease inhibitor in combination with Norvir (ritonavir) or from a non-nucleoside reverse transcriptase inhibitor based regimen should initiate and continue with the standard recommended dosage of Invirase of five 200 mg capsules two times daily with ritonavir 100 mg two times daily. Invirase should be taken at the same time as Norvir (ritonavir) and with or after food.

Like all medicines, Invirase/ritonavir can cause side effects, although not everybody gets them.
When treating HIV infection it is not always possible to differentiate between unwanted effects caused by Invirase or by any other medicines you take at the same time or by the complications of the infection. For these reasons it is very important to inform your doctor of any change in your condition.
The most frequently (in more than ten in a hundred) reported side effects of saquinavir taken with ritonavir concern the gastrointestinal tract, with feeling sick, diarrhoea, tiredness, vomiting, wind and abdominal pain being the most common. Also,changes in laboratory markers (e.g., blood or urine tests) have been reported very commonly.
Other, less frequently reported side effects ( in more than one in a hundred but less than one in ten persons), which may occur are: rash, itching, eczema and dry skin, hair loss, dry mouth, headache, peripheral neuropathy (a disturbance of the nerves in the feet and hands that may take the form of numbness, pins and needles, shooting or burning pain), co-ordination problems, fainting, confusion, weakness, dizziness, depression, anxiety, mood swings, night sweats and hot flushes, inability to sleep, libido problems, taste alteration, warts, mouth ulcers, dehydration, abdominal discomfort, indigestion, fever, pain, constipation, decreased as well as increased appetite, inflammation of gastrointestinal tract, piles, discoloured faeces, visual disturbance, eye pain, raised blood pressure, infections of the respiratory tract, muscle spasms, joint pain, blood collection in the joint, painful urination and infections of the urinary tract, fever and shivering, shortness of breath and chest pain.
Furthermore, inflammation of the liver, fits, allergic reactions, sleepiness and abnormal renal function have been reported.
Your doctor will test your blood regularly to detect possible abnormalities.
Cases of diabetes mellitus or increased blood sugar levels have been reported in patients receiving this treatment or another protease inhibitor.
In patients with haemophilia type A and B, there have been reports of increased bleeding while taking this treatment or another protease inhibitor. Should this happen to you, seek immediate advice from your doctor.
Combination antiretroviral therapy may cause changes in body shape due to changes in fat distribution. 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. Combination antiretroviral therapy may also cause raised lactic acid and sugar in the blood, hyperlipaemia (increased fats in the blood) and resistance to insulin.
There have been reports of muscle pain, tenderness or weakness, particularly with combination antiretroviral therapy including protease inhibitors and nucleoside analogues. On rare occasions these muscle disorders have been serious (rhabdomyolysis).
If you experience any side effects that are not in this leaflet, please tell your doctor or pharmacist. Also, tell your doctor if you have any severe or unusual symptoms or if any side effect that you think you may have gets worse or persists.
