Atazor-R® Tablets for HIV

Atazor-R® combines atazanavir with ritonavir for adult HIV treatment. It is used with other antiretrovirals to help lower viral load. This page explains how it works, who it may suit, and how to compare the Atazor-R price without insurance.

What Atazor-R Is and How It Works

Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing. With US delivery from Canada, you can request this therapy for home use after your prescriber sends a valid prescription. Atazanavir is a protease inhibitor. Ritonavir boosts atazanavir levels by slowing its breakdown. Together, the combination helps block HIV protease, which the virus needs to mature and replicate. This class works best as part of a complete regimen.

Atazor-R tablets should be taken with food. Taking it with a meal improves absorption and helps maintain steady levels. The medicine is typically combined with nucleoside reverse transcriptase inhibitors or another compatible backbone per guidelines.

For background reading on combination therapy approaches, see our overview of modern regimens in A Beginners Guide To Biktarvy. You can also browse our Antivirals category and the condition hub for HIV to compare options.

Who It’s For

This treatment is indicated, with other antiretrovirals, for adults with HIV-1 infection. It may be used in people who are antiretroviral-naive or certain treatment-experienced patients when the background regimen remains active. Individuals with known resistance to atazanavir or with significant drug interactions may need different options. People with moderate to severe liver problems, a history of certain heart conduction issues, or prior severe skin reactions should discuss risks with a clinician before use.

Safety in pregnancy and pediatric dosing require specialized guidance. If you are pregnant, planning pregnancy, or treating an adolescent, your prescriber will follow official labeling and current guidelines to choose appropriate therapy.

Dosage and Usage

The standard adult schedule is once daily with food, taken at the same time each day. When prescribed as the fixed-dose combination, many adults receive Atazor-R 300/100 mg alongside a compatible background regimen. Your prescriber may check for interactions and adjust your overall plan. Swallow tablets whole with water. Do not crush or split unless your prescriber confirms it is permitted. If antacids are needed, separate dosing based on label guidance.

If you also take acid-reducing medicines, timing matters. Some patients must avoid proton pump inhibitors, and H2 blockers or antacids may require spacing. Always review the exact instructions on your prescription label and ask your clinician about any additional medicines.

Strengths and Forms

This product is supplied as film-coated tablets that contain the protease inhibitor atazanavir with the booster ritonavir. Commonly available presentations include atazanavir 300 mg with ritonavir 100 mg in a single oral tablet. Availability can vary by manufacturer and batch. Your order will reflect what our partner pharmacy has in stock at the time of dispensing.

We carry atazanavir ritonavir tablets suitable for use in adult regimens. Country-of-origin details may include India for some lots; see our attribute page for India when relevant.

Missed Dose and Timing

If you miss a dose, take it as soon as you remember with food. If it is almost time for the next dose, skip the missed dose and take the next dose at the regular time. Do not take two doses at once. Consistency supports stable levels and may help prevent resistance. If frequent misses occur, ask your clinician about tools that can help with scheduling.

Storage and Travel Basics

Store tablets at room temperature in the original container. Protect the bottle from moisture and keep the cap tightly closed. Keep out of reach of children and pets. When traveling, pack enough for your trip plus a small buffer in case of delays. Carry your prescription or a copy of the label to avoid issues at security or customs. Use a pill organizer if it helps, and set reminders when changing time zones.

Benefits

This protease inhibitor–based option supports viral suppression when combined with a fully active regimen. Once-daily dosing with food can fit into daily routines. Boosting helps maintain adequate drug exposure. The class may be selected when other regimens are not suitable due to interactions or prior intolerance, as decided by a clinician following current guidelines.

Side Effects and Safety

• Digestive effects: nausea, vomiting, diarrhea, or stomach discomfort
• Headache or fatigue: usually mild and transient
• Skin or eye yellowing: bilirubin elevation can cause jaundice and scleral icterus
• Rash: mild to moderate rashes can occur
• Indirect hyperbilirubinemia: typically benign but cosmetically noticeable

Serious risks are rare but can include severe skin reactions, significant liver problems, heart conduction changes (PR prolongation), kidney stones, or gallbladder issues. Contact a clinician right away for symptoms like severe rash, dark urine, pale stools, chest symptoms, or persistent abdominal pain. People with diabetes may notice changes in blood sugar. Those with liver disease require careful monitoring. This therapy can affect bilirubin labs without indicating liver damage; your clinician will interpret results.

Drug Interactions and Cautions

Interactions are common. Drugs that strongly induce liver enzymes can reduce levels and compromise control. Rifampin and St. John’s wort should not be used. Acid-reducing agents can lower atazanavir exposure; proton pump inhibitors are generally not combined, and H2 blockers or antacids may require spacing per label guidance. Certain statins, such as simvastatin and lovastatin, are contraindicated. Alternatives like atorvastatin at adjusted dosing may be considered by your prescriber.

Other cautions include some antiarrhythmics, sedatives, ergot derivatives, and certain inhaled long-acting beta agonists. Check all prescription drugs, over-the-counter medicines, and supplements with your clinician and pharmacist. If you change therapies within your HIV regimen, ask how those changes affect interaction risk. For context on another protease inhibitor, see our explainer Aptivus For HIV.

What to Expect Over Time

With consistent daily dosing and a fully active background regimen, many patients see improved lab markers over time. Your clinician may monitor viral load and CD4 counts regularly. Some side effects, like mild nausea or indirect bilirubin rises, may appear early and then stabilize. If something feels off, report it promptly. Do not stop or change doses on your own; sudden changes can affect control and resistance patterns. Adherence tools such as alarms, blister packs, or pharmacy synchronization can support steady use.

Compare With Alternatives

Protease inhibitor–based therapy is one option among several HIV classes. If you and your clinician prefer a separate booster with the base agent, some patients consider Atazor 300mg paired with a booster per label. As a non–protease inhibitor choice, Pifeltro (doravirine) may be used within a compatible regimen for certain adults. The right selection depends on resistance history, other conditions, and interaction profiles.

Availability and Substitutions

Supply can vary by lot and manufacturer. If a specific pack is unavailable, your prescriber may recommend an alternative with similar clinical intent. Some patients choose to buy atazanavir ritonavir through a prescriber’s guidance as separate items if a fixed-dose tablet is not in stock. We cannot guarantee restock dates, but we will advise on available options and timing steps once we receive your prescription.

Patient Suitability and Cost-Saving Tips

This medicine may be appropriate for adults who can take a once-daily, food-based regimen and have a compatible background therapy. It may not suit people with significant liver disease, prior serious hypersensitivity, or those using strongly interacting drugs. Discuss pregnancy, plans to conceive, or breastfeeding with your clinician.
