Atazanavir: What It Does and How to Use It

Atazanavir is an HIV protease inhibitor. Doctors use it as part of combination therapy to keep the virus under control. It helps stop HIV from making new virus particles, which lowers your viral load and protects your immune system.

How to take atazanavir

Take atazanavir with food to help your body absorb it. The usual adult dose is 300 mg once daily boosted with ritonavir 100 mg. In some cases an unboosted 400 mg daily dose is used, but your doctor will decide based on resistance tests and other medicines you take. If you miss a dose, take it as soon as you remember unless it’s nearly time for the next dose — don’t double up. Always follow the exact plan your provider gives you.

If you have liver problems, dose changes or extra monitoring may be needed. Atazanavir is cleared by the liver, so tell your doctor about any hepatitis or abnormal liver tests. Pregnant people and those with severe liver disease should discuss risks and benefits with their provider.

Watch for interactions and side effects

Atazanavir has important drug interactions. It needs an acidic stomach to work well, so avoid proton pump inhibitors (like omeprazole) and separate antacids by at least 2 hours. Strong enzyme inducers such as rifampin or St. John’s wort can make atazanavir ineffective and are usually not allowed together. Certain statins (simvastatin, lovastatin) are contraindicated because atazanavir raises their levels. Tell your doctor about all prescriptions, supplements, and herbal products.

Common side effects include nausea, headache, stomach upset, and increased bilirubin that can cause yellowing of the skin or eyes. That yellowing is usually harmless (a benign rise in indirect bilirubin) but can be noticeable. Less common but serious problems include liver toxicity, heart rhythm changes (PR interval prolongation), and kidney stones. If you get dark urine, severe abdominal pain, fainting, or high fever and rash, seek medical care right away.

Your doctor will run blood tests to check liver enzymes and bilirubin after you start atazanavir. Periodic checks of kidney function, lipids, and an ECG may be recommended if you have heart issues or take other drugs that affect heart rhythm.

Practical tips: keep a current list of every medicine you take, take atazanavir with a meal, avoid missed doses, and report new symptoms fast. Don’t share or stop your meds without talking to your provider. With steady use and the right monitoring, atazanavir is an effective option in HIV therapy.

If you have specific questions about dosing with other medications or pregnancy, ask your HIV specialist or pharmacist. They can adjust doses and suggest safe alternatives so your treatment keeps working.

As a blogger, I feel it's essential to discuss the potential risks and considerations of mixing Atazanavir, a medication used to treat HIV, with alcohol. Firstly, consuming alcohol while on Atazanavir can lead to reduced effectiveness of the medication, increasing the risk of the virus spreading. Secondly, alcohol can potentially intensify side effects such as nausea, dizziness, and liver problems. It's crucial to consult with a healthcare professional before consuming alcohol while on Atazanavir. Ultimately, being aware of these risks and taking necessary precautions can help ensure the safety and well-being of those on this medication.
