Can I not stop taking Lenapavir Sodium/Salanca once I take it?

Lenapavir sodium/Lenacapavir is a long-acting HIV-1 capsid inhibitor. Many patients are worried about its "long-acting injection" feature when using it, and believe that once they start taking or injecting it, they cannot stop taking it. In fact, the principle of use of lenapavir sodium is similar to that of other antiretroviral drugs, emphasizing long-term, regular and continuous treatment. However, this does not mean that once taken, it must not be stopped, but that discontinuation is risky and needs to be carried out under the guidance of a doctor.

The treatment of HIV infection (AIDS) follows the core goal of "sustained viral suppression". If the patient interrupts treatment at will, the virus will replicate rapidly and the viral load will rise, which will not only lead to a decline in immune function, but may also accelerate the generation of drug-resistant mutations. Lenapavir sodium has a long half-life, and a single injection can maintain its efficacy for several months. If the patient stops taking it midway and does not replenish other antiviral drugs in time, when the drug concentration drops to the "sub-inhibitory level", it is more likely to induce drug resistance, thus affecting subsequent treatment options.

Therefore, once patients start using lenapavir sodium, they usually need to strictly follow the doctor's dosing plan and use it in combination with other antiretroviral drugs to maintain the continuity of long-term treatment. If the drug needs to be discontinued due to adverse reactions or individual circumstances, doctors will arrange alternative plans based on the specific situation to avoid the risk of drug resistance and viral rebound. This is consistent with the principle of discontinuation of routine oral antiretroviral drugs.

In general, the use of lenapavir sodium is not "unstoppable", but patients cannot interrupt it at will and must manage and adjust it under the guidance of a professional doctor. Its long-acting properties bring the advantage of improved compliance, but also require higher treatment planning and follow-up coordination to ensure maximum efficacy and reduce the risk of drug resistance. For HIV, a disease that requires long-term management, regular and continuous treatment is always the basic principle, and Napavir sodium is one of the powerful tools.
