HelloPharmacist Editorial Team Bottom Line
This three-in-one tablet treats HIV-1 infection, but it carries serious warnings, especially a potentially fatal abacavir allergic reaction. Get the HLA-B*5701 test before starting, keep up with blood tests, and know the warning signs. Take it exactly as prescribed.
⚠️ FDA Boxed Warning — the FDA’s strongest safety alert ▾

This medicine can cause a serious, sometimes fatal allergic reaction (from abacavir). Watch for fever, rash, stomach symptoms, tiredness or aches, and cough or shortness of breath. Stop the medicine and get medical help immediately if you suspect a reaction. Never restart it or any abacavir-containing medicine afterward.

People with the HLA-B*5701 gene are at higher risk and must not take it. Everyone should be tested before starting.

Other boxed risks:

  • Low blood counts (neutropenia and anemia) from zidovudine, especially in advanced HIV disease.
  • Muscle disease (myopathy) with long-term use.
  • Lactic acidosis and severe liver enlargement with fat buildup, including fatal cases.
  • Severe hepatitis B flare-ups in people with both HIV and hepatitis B who stop the medicine. Liver function needs close monitoring for at least several months.

📖 Abacavir, Lamivudine, and Zidovudine: Patient Information Guide

A plain-language walkthrough of Abacavir, Lamivudine, and Zidovudine — what it treats, how it works, how it’s taken, side effects, warnings and interactions. Tap any section to expand it.

What Abacavir, Lamivudine, and Zidovudine is used for

▾

This combination tablet is used for HIV-1 infection.

  • Treatment of HIV-1 infection, together with other antiretroviral medicines.
  • Treatment of HIV-1 infection alone, though data are limited in people with a viral load above 100,000 copies per mL.

How Abacavir, Lamivudine, and Zidovudine works

▾

All three ingredients are nucleoside analogue reverse transcriptase inhibitors. They block the enzyme HIV-1 uses to copy itself, which helps lower the amount of virus in the body.

How Abacavir, Lamivudine, and Zidovudine is taken (dosage)

▾

The tablet is taken by mouth, one tablet twice a day, with or without food. It is for adults and children who weigh at least 40 kg. Because it is a fixed-dose tablet, the dose cannot be adjusted. Follow your prescriber's directions and the label.

Abacavir, Lamivudine, and Zidovudine side effects in detail

▾

The most common side effects in clinical trials were:

  • Nausea
  • Headache
  • Malaise and fatigue
  • Nausea and vomiting
  • Diarrhea
  • Fever and/or chills

Seek medical help right away for signs of an allergic reaction, serious liver problems, lactic acidosis, or low blood counts.

Abacavir, Lamivudine, and Zidovudine warnings and precautions

▾
  • Abacavir allergic reaction: can be fatal. Stop the medicine and never restart it if you suspect one.
  • Low blood counts: zidovudine can cause neutropenia and anemia. Blood counts are checked regularly.
  • Myopathy: muscle problems with long-term use.
  • Lactic acidosis and liver enlargement: including fatal cases, more often reported in women.
  • Hepatitis B flare: may occur after stopping if you also have hepatitis B.
  • Immune reconstitution syndrome: inflammation from old infections as the immune system recovers.
  • Lipoatrophy: fat loss in the face, limbs and buttocks.
  • Heart attack: evidence of a link with abacavir is inconclusive.

Abacavir, Lamivudine, and Zidovudine interactions: what it interacts with

▾

Some medicines can change how this one works or raise its risks.

  • Ribavirin: can worsen anemia, so combining is not advised.
  • Interferon alfa, ganciclovir and other bone marrow suppressive drugs: may raise blood-count toxicity.
  • Stavudine and doxorubicin: work against zidovudine.
  • Methadone: dose may need to rise in some people.
  • Riociguat: dose may need to be lowered.
  • Sorbitol: can lower lamivudine levels.

This is not a complete list of interactions. Always talk with your doctor or pharmacist before starting, stopping, or changing any medication.

Before taking Abacavir, Lamivudine, and Zidovudine

▾
  • Must not be used with the HLA-B*5701 gene or a prior reaction to abacavir, lamivudine or zidovudine.
  • Must not be used with moderate or severe liver impairment.
  • Not recommended with mild liver impairment, creatinine clearance below 50 mL per minute, or weight under 40 kg.
  • Tell your doctor if you have hepatitis B or C.
  • Women with HIV should not breastfeed.
  • A pregnancy registry exists for use during pregnancy. Registry data showed no difference in overall birth defect risk compared with the background rate.

Abacavir, Lamivudine, and Zidovudine overdose: if you take too much

▾

There is no known specific treatment for overdose. You would be monitored and given standard supportive care. In zidovudine overdoses, symptoms were mostly fatigue, headache, vomiting and occasional blood changes, and patients recovered.

Pharmacokinetics: how your body processes Abacavir, Lamivudine, and Zidovudine

▾

All three ingredients are absorbed quickly after swallowing. Abacavir is broken down by the liver, lamivudine is mostly cleared unchanged in the urine, and zidovudine is mainly processed by the liver. None are significantly handled by CYP enzymes. Eating lowers peak levels somewhat but does not change the total amount absorbed.

How to store Abacavir, Lamivudine, and Zidovudine

▾

Store at 25°C (77°F); excursions permitted to 15° to 30°C (59° to 86°F) .

How we combine label and product data

HelloPharmacist combines public FDA and NLM records; we don’t author the underlying clinical facts. We identified 1 FDA-filed SPL label set within the page’s selected clinical scope after exact ingredient or ingredient-combination matching and applicable route/form matching. The representative label is the starting point for the displayed reference monograph; the 12 largest stored in-scope SPL records, which may include that representative, are compared section by section, and the longest available version of each section is retained. Forms, routes, brands, labelers, product-listed strengths, and product-record counts are aggregated separately from ingredient-matched FDA NDC Directory records; package records listed above are associated with the linked SPL; and the normalized concept hierarchy comes from NLM RxNorm.

For canonical ingredient pages, bounded product-attributed indication and administration excerpts may be added to the AI evidence, and the generator is instructed to preserve available product, brand, route, and form qualifiers instead of treating one label as universal. Where a section is identified as AI-written, its plain-language text is generated from bounded label evidence. New draft drug pages remain in the admin review queue before first publication. Lupin Pharmaceuticals, Inc. is the representative DailyMed label linked for verification and dates; it is not the sole source used for the page.

This is general education, not medical advice — always consult your doctor or pharmacist about your medications and any medical condition. For the exact wording of the linked representative label, view that label on DailyMed; some displayed composite sections may come from other in-scope SPL labels.
