Abacavir+lamivudine
About Abacavir+lamivudine
Abacavir+lamivudine is a medicine used with other antiretroviral medicines to treat human immunodeficiency virus type 1 (HIV-1) infection. It contains abacavir and lamivudine, which help reduce the amount of HIV in the blood and support the immune system. Abacavir+lamivudine helps control HIV but does not cure the infection or prevent HIV transmission on its own.
Abacavir and lamivudine work by blocking an enzyme that HIV needs to make new copies of itself. This helps lower the amount of virus in the blood, known as the viral load, and allows the immune system to function more effectively. Maintaining a low viral load helps reduce the risk of HIV-related illnesses and other complications.
Take Abacavir+lamivudine exactly as prescribed by your doctor, preferably at the same time each day. It can generally be taken with or without food. Continue taking it regularly even if you feel well, as missing doses may reduce the effectiveness of treatment and increase the risk of HIV becoming resistant to the medicine. Do not stop taking Abacavir+lamivudine or restart it after an interruption without consulting your doctor.
Common side effects may include nausea, headache, tiredness, diarrhoea, or difficulty sleeping. Abacavir can cause a serious and potentially life-threatening hypersensitivity reaction (a severe allergic reaction), particularly in people who carry the HLA-B5701 gene variation. Your doctor should arrange a blood test for HLA-B5701 before you start treatment. Seek immediate medical attention if you develop symptoms from two or more groups, such as fever; skin rash; nausea, vomiting, diarrhoea, or stomach pain; severe tiredness or body aches; or shortness of breath, cough, or sore throat. If a hypersensitivity reaction is suspected, seek immediate medical attention and follow the instructions given by your doctor or emergency medical team. If your doctor confirms or suspects an abacavir hypersensitivity reaction, never restart Abacavir+lamivudine or any other medicine containing abacavir, as a more severe and potentially fatal reaction may occur.
Before taking Abacavir+lamivudine, tell your doctor if you have liver disease, including hepatitis B or C, kidney problems, heart disease, or risk factors for heart disease. Also tell your doctor about all medicines and supplements you take. If you have hepatitis B and stop taking lamivudine, your liver condition may worsen, so your doctor may monitor your liver function closely after treatment is stopped. If you are pregnant, planning a pregnancy, breastfeeding, an older adult, or considering this medicine for a child, consult your doctor before use.

Habit Forming
Diet & Lifestyle Advise
- Practice strict food safety: Because your immune system is compromised, you are more vulnerable to foodborne illnesses. Wash all fresh produce thoroughly, cook meats to safe internal temperatures, and avoid unpasteurised dairy products.
- Support your bone and muscle health: Long-term HIV treatments can sometimes affect bone density. Incorporate weight-bearing exercises like walking or light resistance training, and ensure you are getting adequate calcium and vitamin D through your diet.
- Stay adequately hydrated: Drink plenty of water throughout the day to help your kidneys process and eliminate the medication efficiently, reducing the risk of strain on your excretory system.
- Limit or avoid alcohol consumption: Alcohol can increase the metabolic load on your liver, which is already working to process Abacavir+lamivudine. Reducing alcohol intake helps minimise the risk of drug-induced liver damage.
- Avoid raw or undercooked seafood: Refrain from eating raw fish, oysters, or sushi, as these can carry specific pathogens that pose severe health risks to individuals managing HIV.

Patients Concern
Disease/Condition Glossary
HIV infection: HIV (Human Immunodeficiency Virus) is a virus that attacks the immune system and destroys the white blood cells that help in fighting infection, 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. HIV 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. However, it can be controlled by treating it with antiretroviral drugs.
FAQs
Abacavir+lamivudine contains Abacavir and Lamivudine. Abacavir+lamivudine works by interfering with the functioning of nucleotide and nucleoside reverse transcriptase enzymes which are necessary for the reproduction of the virus. Together, Abacavir+lamivudine helps in treating HIV infection.

This can occur during the first few months after you stop taking Abacavir+lamivudine. Take the Abacavir+lamivudine strictly as instructed, and do not miss any dose.
You need a genetic blood test to check for a gene variation called HLA-B5701. If you have this gene, you are at a very high risk of developing a severe, life-threatening allergic reaction to one of the ingredients in this medicine. If the test is positive, your doctor will prescribe a different medication. Talk to your doctor to learn more about this test.
Yes, you can take Abacavir+lamivudine with or without food. It does not affect how the medicine is absorbed by your body. However, taking it with a small meal can help if you experience mild nausea when starting the medication. Talk to your doctor or pharmacist if you struggle with stomach upset.
Stopping this medicine suddenly can cause the HIV virus to multiply quickly, which can make the virus resistant to this and other medications. Additionally, if you have chronic Hepatitis B, stopping this medicine can cause a severe, life-threatening flare-up of your liver disease. Talk to your doctor before making any changes to your medication schedule.
Fever or skin rash may be a sign of an abacavir hypersensitivity reaction (a severe allergic reaction), especially if you also have nausea, vomiting, diarrhoea, stomach pain, severe tiredness, body aches, breathing difficulties, cough, or sore throat. Seek immediate medical attention and follow the instructions given by your doctor or emergency medical team. If an abacavir hypersensitivity reaction is suspected, never restart Abacavir+lamivudine or any other medicine containing abacavir.
When taken consistently as part of a complete HIV treatment regimen, Abacavir+lamivudine may help reduce the viral load to undetectable levels. People who achieve and maintain an undetectable viral load do not transmit HIV through sex. Regular blood tests are needed to confirm that your viral load remains undetectable. Ask your doctor about preventing HIV transmission in other situations.
Alcohol may increase the amount of abacavir in your bloodstream and raise the risk of side effects. It may also be unsuitable if you have liver problems. Ask your doctor whether it is safe for you to drink alcohol while taking Abacavir+lamivudine.
If you are pregnant, planning to become pregnant, or breastfeeding, you must consult your healthcare provider before taking Abacavir+lamivudine.
