When your supply of REYATAZ starts to run low, get more from your healthcare provider or pharmacy. It is important not to run out of REYATAZ. The amount of HIV-1 in your blood may increase if the medicine is stopped for even a short time. The virus may become resistant to REYATAZ and harder to treat.
The importance of taking HIV medications regularly
If you don't take your REYATAZ (atazanavir) and other HIV medications every day as directed by your healthcare provider, they may not work effectively. That could lead to an increase in your HIV viral load and decrease your CD4+ cell count, both of which can increase your chances of becoming sick.
Another reason to take your REYATAZ and other HIV medications correctly is that HIV can become resistant to the drugs used to treat it. If the level of an HIV medication in your body drops too low, then it can't effectively prevent HIV from reproducing. This gives the virus a chance to become resistant to that medication and possibly other medications like it.
Setting up and following a regular schedule can help you to remember to take your REYATAZ and other HIV medications once a day. Work with your healthcare provider to set up a treatment regimen that works for you.
To increase your chances of staying on schedule with REYATAZ® (atazanavir), try the following:
- Take REYATAZ at the same time every day with a meal or a snack. If you decide to take REYATAZ with breakfast, lunch or dinner, you are more likely to keep taking it at the same time every day. You can also take REYATAZ with a light snack. Taking REYATAZ with a meal or snack helps it work better.
- Always carry an extra dose or two, in case you're unexpectedly away from home when it's time to take your medicine.
- When you travel, pack your medicine in your carry-on luggage.
- Always refill prescriptions before you run out of REYATAZ (atazanavir). When your supply of REYATAZ starts to run low, it's time to call your healthcare provider or pharmacy for a refill.
It is worth repeating: It is important that you do not miss any doses of REYATAZ or your other HIV medications.
