Question

What happens if I miss a dose?

Hi,
I’m aged 28, female, im starting this new Atroiza today. I’m responsible but what happens if I miss a day or 30 min off drinking my tablet.

Answer

Hi,

Thanks for your email.

The best reason to aim for the same time every day, is so that you get into a good routine. This will help you make your meds an easy part of your life. This is especially true when you first start treatment until your viral load becomes undetectable.

Generally it is OK to have a window of an hour either side of your normal time to take your meds. So if you aim to take it at 9 pm each day so long as you take it between 8pm and 10pm this will all be fine.

Most people will miss a dose at some point, but so long as this is not every week , this is also okay.If this keeps happening, please talk to your doctor about things that might help. The more doses you miss though the more likely that you will develop drug resistance.

Please see this page about adherence for more information.

    Hi i was given the ARVs to use immediately after I tested and it was positive. Still waiting for the blood test so I took only one pill of ARVs and I stopped till I get the result I want to know if that would put me in danger if I carry on after receiving my results?

    Hi Annonimouse ssaqs,

    It happened just once, so it shouldn’t make difference. It’s good that you took the tablet when you remembered.

    Hi Dee,

    Yes, you can go back to your normal time.

    If you occasionally miss 1 or 2 doses of Trivenz it’s unlikely to do any harm. Please see this Q&A for more info.

    Hi Sarvesh,

    Its perfectly fine to take your meds a few hours either side of your normal time.

    Hi Somikazi,

    Yes, you can take them at 23.53pm. Please see this link to a similar Q&A.

    If you have missed a dose you should take it as soon as you remember. If you have only realised when you’re taking your next dose do not take a double dose. Almost everyone will be late or miss a dose occasionally. However this becomes a concern if it is happening regularly.

    Hi Gladys,

    If the meds are the same, then yes.
