Darunavir
About Darunavir
Darunavir belongs to a class of antiretroviral drugs called protease inhibitors primarily used to treat HIV (Human Immunodeficiency Virus) infection in adults and children aged 3 years and above weighing at least 15kg. HIV is a virus that targets the immune system, primarily white blood cells. HIV destroys white blood cells and reduces a person's resistance to infections.
Darunavir contains Darunavir that works by inhibiting a protein called protease, which is required by virus-infected cells to generate new viruses. As a result, Darunavir reduces the amount of HIV in the body. Thereby, helps improve the immune system and lowers the risk of developing any illness related to HIV infection.
Take Darunavir with food. Your doctor will decide the dose and duration based on your medical condition. In some cases, Darunavir may cause certain common side effects such as headache, nausea, dizziness, abdominal pain, diarrhoea, and vomiting. Most of these side effects do not necessitate medical treatment and fade away with time. Please check with your doctor if the side effects persist or worsen.
Consult your doctor before taking Darunavir if you are pregnant. Due to the risk of HIV transmission, women infected with HIV are recommended not to breastfeed. Darunavir may cause dizziness, so drive only if you are alert. Darunavir should not be given to children below 3 years of age or weighing below 15kg as safety and effectiveness have not been established. Avoid or limit alcohol consumption as it may cause increased dizziness. Keep your doctor updated about your health condition and medications to rule out any interactions.

Habit Forming
Diet & Lifestyle Advise
- Take care of your mental health. Fear and anxiety can hamper the immune system as well. Therapy, yoga, and meditation effectively provide peace of mind.
- Spending time with family or doing whatever makes you happy might help minimise emotional and physical stress.
- Never exchange personal objects that have been contaminated with bodily fluids or blood, such as razor blades or toothbrushes.
- Never share used needles, other injection or drug equipment as it may spread viruses.
- Use condoms for safe sex; it helps to reduce contact with sperm and vaginal fluids.
- Other sexually transmitted infections, such as gonorrhoea or syphilis, can make you more susceptible to HIV infection.
- Consume a well-balanced diet. Include vitamin and nutrient-rich foods like dark-green, yellow, orange, red vegetables and fruits to enhance your immune system. Choose lean protein and whole carbohydrates over-processed foods.
Special Advise
- Monitoring liver function before and during medication, especially in individuals with underlying chronic hepatitis, or cirrhosis.
- Glucose levels should be monitored. During post-marketing surveillance, hyperglycemia has been found in HIV-infected patients receiving protease inhibitor medication.
- It is essential that you do not miss or skip any doses while on treatment. If you miss a dosage of Darunavir, take it as soon as you remember. However, if it is time for the next scheduled dose, skip the missed dose and take the scheduled dose. Avoid double dosing.
Patients Concern
Disease/Condition Glossary
HIV infection: HIV (human immunodeficiency virus) is a virus that damages immune system cells and impairs your ability to fight infections and diseases. 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. It 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 treatment with antiretroviral drugs.
FAQs
Darunavir works by inhibiting protease enzyme that is essential for the reproduction of the human immunodeficiency virus. Thereby, it prevents the production of the new human immunodeficiency virus. Thus, Darunavir lowers virus load in the body and helps treat the infection.
Some patients taking antiretroviral combination therapy may develop osteonecrosis (death of bone tissue due to loss of blood supply to the bone). If you experience joint ache, pain, stiffness, or difficulty movement, consult your doctor.
In some cases, Darunavir may cause a rash, especially when used in combination with raltegravir. A rash is generally mild to moderate. However, occasionally it may become severe. Please inform your doctor if you develop a rash.
Darunavir might increase sugar levels in the blood, therefore, consult your doctor before taking Darunavir if you are diabetic. You are advised to monitor your blood glucose levels regularly while taking Darunavir.
Do not stop taking Darunavir without consulting your doctor as it may reduce the effectiveness of anti-HIV therapy. Continue taking Darunavir for as long as your doctor has prescribed it to you to treat your condition effectually. Do not be reluctant to speak with your doctor if you experience any difficulty while taking Darunavir.
