Q and A


Is it OK to take TB meds as well as ARVs?

I’ve been taking my ARVs together with my TB resistance tablet, will this affect it working on my body?


Thanks for getting in touch.

Its very common that someone who is positive and on ARVs will also be using TB drugs. They’ll both work as they should do. The ARVs on the HIV, and the TB drugs will help prevent you contracting TB.

    Hi Unathi,

    If you live in a TB prone zone, then yes you may need to take the TB meds. However, this is something that will need to be discussed with your doctor.

    Hi Vuyokazi,

    Your CD4 count is high and your HIV is under control. If you’re having other health issues you’ll need to discuss this with a doctor.

    Hi King,

    Is your girlfriend taking HIV meds? Isoniazid is taken by HIV positive people to treat or prevent TB. I hope she’s doing well.

    If your girlfriend’s viral load is undetectable on HIV treatment (ART) the risk to you of HIV is zero, even if you don’t use condoms. Unfotunately we are not doctors at i-Base but you can talk to your doctor about TB if you think you have been affected.
