Reyataz® Capsules for HIV-1

Atazanavir is an HIV protease inhibitor used with other antiretrovirals. It helps lower viral load as part of a complete regimen prescribed by your clinician. This page explains how the medicine works, who it suits, and ways to manage treatment and access.

What Reyataz Is and How It Works

With US delivery from Canada, you can access this treatment through our platform. Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing. The active ingredient blocks the HIV-1 protease enzyme. That action prevents maturation of new viral particles. The therapy is taken with other HIV medicines to support viral suppression. Many patients pay cash for Atazanavir without insurance when coverage is limited or deductibles are high.

It is usually given once daily with food. It may be used with a booster such as ritonavir or cobicistat based on the label and prescriber direction. Always follow the official prescribing information provided with your medicine.

Who It’s For

This medicine is indicated for adults and certain adolescents with HIV-1 infection, in combination with other antiretrovirals. Some patients start therapy after baseline labs and genotype testing. Others switch from another regimen when appropriate. Reyataz brand Atazanavir should not be used in patients with known hypersensitivity to atazanavir. People with moderate to severe liver problems may not be candidates. Those with a history of heart conduction issues should discuss risks. For broader context on condition care, see our HIV category and this overview of testing methods in HIV Test Types.

Dosage and Usage

Follow your prescriber’s instructions and the package insert. Standard adult regimens often use once-daily dosing with food. When a booster is prescribed, take both medicines together at the same meal. Swallow capsules whole with water. If your clinician advises an acid-reducing agent, spacing may be required. Proton pump inhibitors and H2 blockers can affect absorption; clinical guidance varies by experience status and booster use. Defer to the official label or your healthcare professional for specifics.

If you start or stop other medicines, inform your prescriber promptly. Take doses at the same time every day to support adherence. If you miss several doses, do not try to “catch up”; contact your clinician for advice. For pediatric or weight-based dosing, see the full prescribing information.

Some adults take a dose that aligns with Atazanavir 300 mg capsules when combined with a pharmacokinetic enhancer, per label. Your clinician will confirm your schedule.

Strengths and Forms

Common presentations include capsules for adults and an oral powder for pediatric patients. Available strengths include 150 mg, 200 mg, and 300 mg capsules. Availability may vary by manufacturer and market. The oral powder is typically mixed as directed and taken with food; caregivers should review label instructions before use.

Missed Dose and Timing

If you miss a dose, take it as soon as you remember unless it is close to the time of your next dose. Do not take two doses at once. If vomiting occurs shortly after taking the medicine, check the package insert or contact your healthcare professional for guidance. Aim for consistent daily timing with a meal, which supports absorption and may reduce stomach upset.

Storage and Travel Basics

Store capsules at room temperature in a dry place, away from excess heat and moisture. Keep the bottle tightly closed and out of reach of children and pets. Do not transfer pills to unlabelled containers. When traveling, carry your medication in original packaging with the prescription label. Pack it in your carry-on to avoid temperature extremes and lost luggage. Keep a copy of your prescription and a medication list in case you need to speak with a clinician while away.

Benefits

This protease inhibitor can help maintain viral suppression as part of a complete antiretroviral regimen. Once-daily dosing with food may fit many routines. A long track record and flexible pairing with other agents provide prescribers with familiar options. For people looking to simplify schedules, a single daily dose can aid adherence when clinically suitable.

Side Effects and Safety

• Common: nausea, diarrhea, headache, abdominal pain
• Skin: mild rash can occur
• Eyes/skin: yellowing from benign bilirubin increases
• General: fatigue, insomnia

Serious but less common risks include significant skin reactions, liver problems, gallstones, kidney stones, and heart conduction changes (PR interval prolongation). Inform your prescriber immediately if you notice severe rash, jaundice with pain, dark urine, chest symptoms, or signs of an allergic reaction. Immune reconstitution may occur when starting combination antiretroviral therapy.

Drug Interactions and Cautions

Atazanavir is metabolized by CYP3A. Strong inducers (such as rifampin or St. John’s wort) can reduce levels and are generally contraindicated. Some statins, antiarrhythmics, benzodiazepines, and ergot derivatives may require avoidance. Acid-reducing agents can lower absorption; timing and maximum doses depend on whether a booster is used and on treatment experience. Tenofovir may influence exposures; clinicians often consider corresponding adjustments within the regimen. Discuss all medicines, vitamins, and herbal products with your prescriber. For perspective on alternative HIV options, see this article: Aptivus Guide.

What to Expect Over Time

With consistent daily use in a complete regimen, many people see improved lab results at routine monitoring visits. Your clinician will track viral load and CD4 counts, and check liver function, bilirubin, and renal labs as needed. Some side effects appear early and fade as your body adjusts. Keep taking your medicine as prescribed unless your prescriber tells you to stop. If diet changes or interacting medicines are needed, your care team will advise on timing strategies.

Education and support matter. Reading about other options can help you prepare for discussions; see our overview in Biktarvy Guide.

Compare With Alternatives

Other options in HIV care depend on resistance patterns, prior therapy, and tolerability.

Some adults use capsule strengths aligned with Atazanavir 300 mg capsules when clinically indicated. Your care team will determine the right option.

Patient Suitability and Cost-Saving Tips

This therapy may suit adults who can take a once-daily protease inhibitor with food and who have no contraindicated interactions. It may not suit those with significant hepatic impairment or certain cardiac conduction abnormalities. To reduce out-of-pocket costs, consider multi-month fills if your prescriber agrees. Set refill reminders so you do not miss doses. Ask your clinician about lab timing to bundle tests and visits efficiently. If insurance changes, check cash-pay options and compare Canadian pricing in our Antivirals category.
