Question

What are the pills marked with M171 and D100?

Answer

If your doctor prescribed HIV medication that looks like the pill in the picture and has M171 embossed, this is likely to be Tribuss.

Picture: Tribuss, manufactured by Aspen.

The picture is not very clear, but M171 is one one side and D100 is on the other.

This is based on the information at this website.

Tribuss is a generic version of Atripla and it is manufactured by Aspen. It is widely used in South Africa.

Just like Atripla, Tribuss contains three active HIV drugs – efavirenz, tenofovir-DF and emtricitabine.

Sometimes Tribuss is mainly used as an HIV treatment by people who are HIV positive. However, this is an older treatment that is steadily being switched to newer drugs in many countries.

Some countries use Tribuss as a way to prevent HIV after recent risk for people who are HIV negative. This way of using HIV meds is called PEP. Tribuss is not recommended as PEP in most countries though because of the risk of side effects that are higher in people who are HIV negative.

    Will prep treatment really help if I’ve been sleeping with a person that has been taking blue pills written M117 for 3 years and all along I’ve been being tested and my results are always negative.

    Hi Alex,

    It sounds like you’re taking the same meds, (please see the post), if this is the case, then yes you can take them.

    Hi Siyabulela,

    It could be another drug, for another condition. Especially if the pills don’t look the same size and colour as the pills above. What did the doctor say?

  7. Siyabulela

    Does M171 pills for HIV if is not having D100?

    Hi Nkele,

    If your sister is on ARVs that’s great because this treatment can benefit her health. But it is her decision, of course, whether she wants to talk about it.

    Hi Nkele,

    Thanks for this. Yes, we have to keep taking our meds everyday about the same time. But lots of research is looking at long acting meds. So in future it might be a bit easier.
