Uses

HIV infection occurs when a person's immune system is attacked and weakened by the human immunodeficiency virus (HIV). This infection progressively weakens the immune system, making individuals more susceptible to opportunistic infections.

It is an orally available prescription drug. Your doctor will decide the dose and duration of the drug based on the disease condition and other factors. Always take Lopinavir and Ritonavir as prescribed by your doctor. Take the tablet with or without food. Do not break, chew, crush, or break the tablet. Swallow the whole tablet with water.

Side Effects

The most common side effects of Lopinavir, Ritonavir are diarrhoea and increased lipid levels in the blood. Serious side effects can also occur such as severe allergic reactions like lactic acidosis, changes in body fat, inflammation of the pancreas, liver problems, and high blood sugar.

Warnings

Suppose you have Hepatitis B, Hepatitis C, or other liver problems. In that case, you may have a greater risk of developing new or worsening liver illness during treatment with lopinavir and Ritonavir. Tell your healthcare provider immediately if you have any signs and symptoms of liver problems, such as loss of appetite, dark-colored urine, yellow skin and whites of eyes(jaundice), and pale-colored stools. People with high levels of certain fat (triglycerides) have a greater chance of developing pancreatitis(a condition caused by inflammation of the pancreas, a gland behind the stomach). If you have a history of pancreatitis, you may have a greater chance of it returning during treatment with this drug.

Precautions

During the early stages of HIV-1 treatment, some patients may experience an inflammatory response to opportunistic infections. This condition is called immune reconstitution syndrome. It can occur after starting the drug or other antiretroviral therapies. Knowing this possibility and monitoring for any signs of worsening infections or inflammatory symptoms is necessary. Inform your healthcare provider if the symptoms concern you or persist longer than usual. It is advised to avoid using the drug if you are mainly allergic to it or its ingredients. Tell your doctor about all the medications you have been taking recently, including herbal and supplements, before taking this drug.

Word of Advice

To prevent HIV-1 transmission, avoid sharing needles or syringes. Individuals who use injectable drugs must use sterile needles and syringes and never share them with others. Personal items such as toothbrushes, razor blades, or anything with blood or body fluids on them should not be shared, as HIV-1 can be present in blood and certain body fluids, and sharing these items may transmit the virus. Lopinavir and Ritonavir are unsafe during breastfeeding because HIV infection can be transmitted to the infant through breast milk; alternative feeding methods should be considered to support the infant's nutrition. If you miss a dose of Lopinavir and Ritonavir for an entire day, take your usual dose the next day. Do not take a double dose.
