Q and A

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.

    Hi Lorenzo,

    Please can you ask why the clinic told your partner she must wait 3 weeks?

    Was your partner taking Tribuss (M171) before she missed the doses? And is she taking them again now?

    Please talk to the clinic about taking M171. You can also ask if you should take PEP or PrEP, depending on your risk if you’ve not been using condoms.

    Hi! my partner is HIV positive she missed taking pills for a week and nurses at the clinic said she must come after 3 weeks. She suggested me to take M171 pill not to be infected. Is this true?

    Hi Zakhele,

    The medication that your partner is taking is a generic version of Atripla. Its commonly used by a lot of people. If you want to know how long your partner has been positive for, the best thing is to ask her.

    Hi Thobile,

    If your partner is on medication and his viral load is undetectable, there’s no risk of transmission. Please see here: http://i-base.info/u-equals-u/

    If you still want to access PrEP, please contact the following organisation: https://tac.org.za/ they are based in South Africa.

    Hi Loveness,

    As long your HIV is under control, there’s no risk of your transmitting HIV to your partner. Please see here: http://i-base.info/u-equals-u/ This means that it’s safe to have sex without a condom.

    With regards to having a child, its not possible to predict what a child’s status will be. However, if your HIV is under control, the risk is drastically reduced. Please see here:http://i-base.info/guides/pregnancy
