For newly diagnosed Persons Living with HIV (PLHIV), among their top concerns are the possible side effects that might come once they start treatment. These side effects may have an impact on their way of life, especially at work and their studies. In this article, we will try to tackle the different antiretroviral (ARV) drugs, their possible side effects, and how to handle these side effects so as not to affect the PLHIVs way of life.

Antiviral Drugs

Antiretroviral or ARV is an inhibitor drug that blocks HIV from attaching to cells of immunity specifically the CD4 cell (also known as T-cell or T helper cells) and prevents it from multiplying. It has to be taken daily to suppress HIV and prevent the decline of the body's natural defense caused by the virus .

Below are the various ARV drugs and the possible side effects that may occur upon taking said component:

Managing ARV Treatment

The purpose of having ARV treatment for PLHIV is for them to achieve being Undetectable and eventually have a normal life despite their status. But this can only be achieved by consistent and adherent intake of their ARV.

It is important that the set schedule in taking the ARV should strictly be followed to ensure: 1) efficacy of the treatment, and 2) minimize its side effects. Change in the schedule of drinking ARV should be consulted with the medical team. It is recommended that an alarm be set preferably in the Client's mobile device to remind him daily of his time for drinking his ARV. Also, relating the time in drinking his ARV for something he does daily (e.g. sleeping at night, eating dinner, etc.) can help in reminding him of this schedule in drinking his ARV.

Any recurring side effects despite performing the suggested intervention should immediately be consulted with the treatment doctor. Scheduled follow-ups to the treatment center especially for viral load testing should be routinely done to ensure monitoring of the efficacy of the treatment.

And most important, PLHIV should monitor his ARV supply if he has enough for at least three (3) months. It is advised to have a refill if ARV supply is less than two (2) weeks worth. Despite the community quarantine in place, clients enrolled in LoveYourself Treatment Centers can now request for ARV refill at the convenience of their home via Xpress Refill.
