Dear Lillian,
Find below what I have worked on for your consideration.
Question
Dear doctor, my husband and I are both HIV positive and have been doing well on ARVs until recently when they were changed from tenofovir, lamivudine and efavirenz to tenofovir, lamivudine and dolutegravir. Fortunately for my husband, he likes the new regimen and is happy but for me I cannot tolerate it. I developed constipation and my stomach is always bloated making it difficult for me to continue taking them and yet when I reported my problems to my doctor, I was told to drink more and eat fruits that would help solve the problem but it hasn’t. I have actually stopped taking it and gone back to my old ARVs because I still had some from the old supply. The old regimen was working for me perfectly well and I am ready to buy it because the new one makes me miserable. Please advise. Sarah.
Answer
Dear Sarah, the right thing to do is to be open with your doctor and tell him or her that you cannot tolerate the new regimen of tenofovir, lamivudine and dolutegravir (TLD), to which many people are being switched to according to the new guidelines. Most people who have been switched to TLD from tenofovir, lamivudine and efavirenz (TLE) are happy but those who have challenges like you need to be listened to. It is true that compared to efavirenz, dolutegravir is smaller (50 mg compared to 600 mg of efavirenz) and therefore easier to swallow, has fewer side effects and has a higher barrier to resistance compared with efavirenz and nevirapine, which means it can be used for a longer time without the virus developing resistance to it. However, like any other medicines, it has side effects including those that have never been documented hence the need for continued pharmacovigilance, which is the practice of monitoring the effects of medical drugs after they have been licensed. This is necessary in order to identify possible side effects not noticed before the drug was licensed. What can be done for you is to give you the optimized dose of efavirenz, which is 400 mg, because it has been found to be as effective as efavirenz 600 mg. However, you should discuss with your doctor this possibility instead of returning yourself to the old regimen without his or her knowledge. Antiretroviral therapy is treatment for life and in order for it to succeed there must be mutual trust between doctor and patient.
