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 Lis,

    When someone first starts meds, it’s important that they try and adhere to their medication. However, you’ll be OK with missing the one dose.

    Hi Adelaide,

    Missing a dose of meds every now and then won’t be an issue. However, it’s important to try and take your meds at roughly the same time very day, as this ensures that you have the right levels of ARVs.

    Hi Vivian,

    Though not ideal, you should be OK, this is because it takes a week or so for a persons viral load to rebound. If you can just for peace of mind it may be worth having a viral load test.

    I lost my medication on my way back so i missed my medication for 4days. Me and my husband are discordant couple and during that time we had sex . am scared what if i infected him. It was only 4 days. My status are un detectable and i have been like this since 2010. We have sex without protection and he has remained negative for all this time. Please advice. Am 20yrs today living with HIV.

    Hi Ran,

    As the above post explains, this can and does happen. If it isn’t something that happens all the time, then it won’t be an issue.
