If you’ve seen the name lopinavir on a prescription label, you’re probably wondering what it does. In plain terms, lopinavir is an antiviral drug that blocks HIV from multiplying in your body. It’s usually combined with ritonavir – another antiviral – to boost its effect and keep the virus at bay.
Because it targets a specific step in the HIV life cycle, lopinavir helps lower viral load, supports immune function, and reduces the risk of complications. You’ll often hear it referred to by the brand name Kaletra, but the active ingredient is still lopinavir.
The standard adult dose for HIV treatment is one tablet (containing 100 mg lopinavir and 25 mg ritonavir) taken twice daily with food. Food helps your body absorb the medication better, so try to take it with a meal or snack.
If you’re on a pediatric regimen, the dosage depends on weight and is measured in milligrams per kilogram. Your doctor will calculate the exact amount for kids to keep the drug effective without causing unnecessary side effects.
Don’t skip doses even if you feel fine – missing pills lets the virus rebound and can lead to resistance. If you forget a dose, take it as soon as you remember unless it’s almost time for your next one; then just continue with the regular schedule.
Most people tolerate lopinavir well, but you might notice some mild reactions. The most common are stomach upset, nausea, and diarrhea. Taking the pill with a solid meal usually eases these issues.
A less frequent but important side effect is increased liver enzymes, which can signal stress on your liver. Your doctor will order regular blood tests to catch any problems early. If you experience severe abdominal pain, yellowing of skin or eyes, or persistent vomiting, call your healthcare provider right away.
Because lopinavir interacts with many other drugs, always tell your pharmacist about every medication, supplement, and over‑the‑counter product you use. Certain statins, anti‑arrhythmics, and some antibiotics can boost or lower lopinavir levels, affecting how well it works.
Alcohol isn’t banned while on lopinavir, but heavy drinking adds strain to the liver and may worsen side effects. Moderation is key.
Pregnant or breastfeeding women should discuss risks with their doctor; lopinavir is generally considered safe during pregnancy but close monitoring is recommended.
Overall, lopinavir is a cornerstone of modern HIV therapy when taken correctly. Stick to the dosing schedule, watch for side effects, and keep open communication with your healthcare team – that’s the best way to stay on top of your health.
