The whole question

Dear GroundUp

Can I change the time of taking my ARVs? I switched to a different type of ARV a week ago and have been taking them in the morning as usual. Now I feel fatigued and nauseous. Can I take my medication at night instead?

The long answer

Switching the time of your medication will not be a problem. It is important that you find a time that works best for you. Take your usual dose in the morning and then start that same day with an evening dose. This prevents a 24-hour gap. From this point, you can take your ARVs at the same time every evening instead of in the morning. You will likely have increased drug levels in your body the following day but it is unlikely to cause significant side effects.

It might be worth asking why you have recently switched your medication. We suggest that you visit your pharmacist or doctor who can best explain how to change the timing of your medication.
