Atazanavir+ritonavir
About Atazanavir+ritonavir
Atazanavir+ritonavir is a prescription medicine used, in combination with other antiretroviral medicines, to treat Human Immunodeficiency Virus type 1 (HIV-1) infection. It contains atazanavir, which helps prevent HIV from multiplying, and ritonavir, which increases the amount of atazanavir in your body so that it works more effectively. Together, they help lower the amount of HIV (viral load), which can help protect your immune system and reduce the risk of HIV-related complications.
Although Atazanavir+ritonavir helps control HIV infection, it does not cure HIV or prevent the virus from spreading to others. Continue following your doctor's advice and practise safer sex to help reduce the risk of HIV transmission.
Take Atazanavir+ritonavir exactly as prescribed, at the same time every day and with food, as food helps improve the absorption of atazanavir. Before starting treatment, your doctor may perform blood tests, including resistance testing, to help determine whether this medicine is suitable for your HIV strain and to guide treatment decisions.
Missing doses or stopping treatment without medical advice may allow HIV to become resistant to treatment, making the medicine less effective. Eating a balanced diet, staying physically active, avoiding smoking, and attending regular follow-up appointments may help support your overall health during treatment.
Like all medicines, Atazanavir+ritonavir may cause side effects, although not everyone experiences them. Contact your doctor promptly if you develop a severe skin rash, persistent abdominal pain, symptoms of liver problems, a slow or irregular heartbeat (called PR interval prolongation), or symptoms of kidney stones, such as severe pain in your side or back, pain while passing urine, or blood in the urine.
Before taking Atazanavir+ritonavir, tell your doctor if you have liver disease, kidney disease, diabetes, haemophilia, or heart rhythm problems. Also inform your doctor about all prescription medicines, over-the-counter medicines, herbal products, and supplements you are taking, as some may interact with this medicine. If you have an existing heart condition or are taking medicines that affect heart rhythm, your doctor may recommend an electrocardiogram (ECG) before starting treatment and during follow-up. If you are pregnant, planning to become pregnant, breastfeeding, or are an older adult, consult your doctor before taking this medicine.

- Take with food: Always take this medicine with food to help your body absorb atazanavir properly.
- Do not stop treatment: Continue taking Atazanavir+ritonavir unless your doctor advises you to stop, even if you feel well.
- Regular monitoring: Keep all follow-up appointments and blood tests. Your doctor may monitor your viral load, CD4 cell count, liver function, blood sugar, cholesterol levels, and kidney function during treatment.
- Heart monitoring: If you have a heart condition or take medicines that affect heart rhythm, your doctor may recommend an electrocardiogram (ECG) before starting treatment and during follow-up.
- Inform your healthcare providers: Tell your doctor, dentist, surgeon, and pharmacist that you are taking Atazanavir+ritonavir before starting any new medicine or undergoing a medical or dental procedure.
- Stay hydrated: Drink plenty of water during treatment, as this may help reduce the risk of kidney stones.
- Watch for new symptoms: Tell your doctor if you develop new or worsening symptoms after starting treatment. This may be due to immune reconstitution inflammatory syndrome (IRIS), which can occur when your immune system begins to recover and responds to infections already present in your body.
- Prevent HIV transmission: Continue practising safer sex and avoid sharing needles or other injection equipment, as Atazanavir+ritonavir helps control HIV but does not prevent HIV transmission.
Drug Interactions

Patients Concern
Disease/Condition Glossary
HIV infection: HIV (human immunodeficiency virus) is a virus that attacks the immune system, making the individual susceptible to other infections or illnesses. People with HIV experience flu-like symptoms such as fever, chills, rash, night sweats, muscle aches, tiredness, and sore throat. These symptoms usually last for days to several weeks. It spreads through body fluids such as semen, vaginal fluid, and blood. If left untreated, this condition can lead to AIDS (Acquired Immunodeficiency Syndrome). It is a life-long condition, and there is no definite cure for it. However, it can be controlled by treating with antiretroviral agents.
FAQs
No. Atazanavir+ritonavir should always be taken with a full meal or a substantial snack, as food is necessary for your body to absorb the medicine properly and ensure it works effectively against HIV. Do not take it on an empty stomach. If you have difficulty taking it with food, speak with your doctor or pharmacist.
No. Atazanavir+ritonavir does not cure HIV or AIDS. It is an antiretroviral medicine that helps control the virus by reducing the amount of HIV in your body (viral load), supporting your immune system, and lowering the risk of opportunistic infections. Continue taking it exactly as prescribed and discuss your long-term treatment plan with your doctor.
Yellowing of the skin and the whites of your eyes is a common, usually harmless side effect of this medicine. However, you should still contact your doctor right away to confirm that it is not a sign of liver damage, especially if you also experience dark urine, pale stools, or abdominal pain. Talk to your doctor to monitor your health.
Certain acid-reducing medications can prevent your body from absorbing Atazanavir+ritonavir properly, making it less effective. You should discuss all your current medications with your healthcare provider, as you may need to space out your doses or avoid certain heartburn drugs entirely. Talk to your doctor or pharmacist for specific guidance.
It is highly recommended to limit or avoid alcohol while taking this medicine. Alcohol can increase stress on your liver and worsen some of the common side effects of the medication, such as nausea and dizziness. Talk to your doctor about safe alcohol consumption limits.
You must discuss your pregnancy plans or current pregnancy status with your healthcare provider. Managing your HIV treatment during pregnancy is vital to protect both your health and to prevent transmitting the virus to your baby, but your doctor may need to adjust your treatment plan. Talk to your doctor for personalised advice.
If you miss a dose, take it with food as soon as you remember, unless it is almost time for your next scheduled dose. Never take two doses at the same time to make up for a missed one, as this can increase your risk of severe side effects. Talk to your doctor or pharmacist if you frequently miss doses.
Yes, this medicine can lower the effectiveness of hormonal contraceptives, increasing the risk of unplanned pregnancy. It is recommended to use a reliable, non-hormonal backup birth control method, such as condoms, while using this medication. Talk to your doctor to find the best contraceptive option for you.
Not everyone needs to change their HIV treatment. However, your doctor may recommend switching to a different treatment regimen if the virus becomes resistant to the medicine, troublesome side effects develop, important drug interactions occur, or another treatment is better suited to your health needs. Your HIV specialist will determine the most appropriate treatment based on your medical history, treatment response, and test results. Do not stop or switch your HIV medicines without your doctor's advice.
