Tribuss as PEP and the side effects

I’m on day 7 of my 28 day PEP treatment using tribuss. I am unable to sleep as I tend to have serious nightmares. When I wake up the following day I have massive dizziness like those experienced during a bad hangover. Is there a remedy for this as I am very concerned about the three weeks ahead


Hi there,

Thanks for getting in touch.

Dizziness is a common side effect when taking ARVs that contain efavirenz. They do though usually go within a few weeks. For more info please see the following:


Because you’re only taking ARVs for 28 days, if the side effects continue, they will go when you stop taking tribuss.

    Hi Anonymous,

    Yes Tribuss can be taken when pregnant, it won’t have an impact on a baby. If you might be pregnant it’s important that once you’ve finished this course of PEP that you have a HIV test.

    Good day, I’m taking Tribuss as a PEP after exposure to Hiv. I think I might be pregnant, even though it’s still too early to confirm my pregnancy. Is it still safe to continue with the treatment?
    Thank you,

    PEP needs to be taken for 28 days. It is however up to you if you wish to stop taking the Tribuss.

    Hi Ano,

    I’m not sure about your comment. Are you HIV positive and taking Tribuss? Please let us know.

    What happens if you are prescribed Tribuss and stop it midway because you had unprotected sex and you assume the other person was positive and only find out that she is not?

    Hi Norman,

    Why were you prescribed other meds? Were you having problems with Tribuss? How long have you been on your new combination?

    If you’re having side effects and you’ve been on the new combination for more than a few weeks, you may need to change.
