Stavudine – What You Need to Know

Stavudine, a nucleoside reverse transcriptase inhibitor (NRTI) used to treat HIV infection. Also known as d4T, it works by blocking the reverse transcriptase enzyme that the virus needs to copy its genetic material. This drug is a core component of antiretroviral therapy, the combination of medicines that keep HIV from replicating. Because HIV, the virus that attacks the immune system mutates quickly, doctors often pair Stavudine with other drug classes such as protease inhibitors or non‑nucleoside reverse transcriptase inhibitors. The relationship can be summed up in a few triples: Stavudine is a NRTI; NRTIs support antiretroviral therapy; antiretroviral therapy reduces HIV viral load. Below we break down how this works in real‑world settings.

How Stavudine Is Used in Everyday Treatment

When doctors prescribe Stavudine, they typically start with a dose of 30 mg twice daily for adults, adjusting based on weight and kidney function. The drug must be taken with food to improve absorption and to lessen stomach upset. Because the medication stays in the bloodstream for several hours, missing a dose can cause the virus to rebound, so adherence is critical. Monitoring includes regular blood tests: a baseline CD4 count, viral load measurements every 3–6 months, and liver function panels to watch for toxicity. If a patient shows signs of peripheral neuropathy—tingling or numbness in the hands or feet—doctors may lower the dose or switch to another NRTI like lamivudine. Stavudine’s cost advantage makes it attractive in low‑resource settings, but clinicians weigh that against its side‑effect profile. The drug’s efficacy in lowering viral load is comparable to newer agents, yet its long‑term safety concerns have led many countries to phase it out in favor of tenofovir or abacavir.

Side effects are the biggest reason patients and providers talk about alternatives. Common issues include nausea, headache, and fatigue, but the most serious are peripheral neuropathy, lipoatrophy (fat loss from the face and limbs), and mitochondrial toxicity that can affect the liver and muscles. Regular physical exams help catch these problems early; if neuropathy appears, switching to a less neurotoxic NRTI often restores comfort. In addition to medical monitoring, lifestyle choices matter: avoiding alcohol, staying hydrated, and maintaining a balanced diet can reduce symptom severity. For pregnant women, Stavudine is classified as a Category C drug, meaning risk cannot be ruled out, so obstetricians usually prefer safer alternatives. The drug’s legacy in global health is clear—it helped millions access life‑saving therapy when newer drugs were unaffordable. Today, its role is more niche, reserved for cases where cost constraints outweigh the risk profile.
