Why is this medication prescribed?

Doravirine is a medication used in the treatment of HIV infection. It belongs to a class of drugs called non-nucleoside reverse transcriptase inhibitors (NNRTIs), which work by blocking the action of the enzyme reverse transcriptase, thus preventing the HIV virus from multiplying in the body.

Doravirine is often prescribed as part of a combination therapy regimen along with other antiretroviral medications to effectively manage HIV infection and reduce the viral load in the bloodstream, improving immune function and reducing the risk of developing AIDS-related complications.

How should this medicine be used?

Doravirine is typically prescribed as a tablet to be taken orally, usually once daily. Here’s a general guide on how to use doravirine:

  • Dosage: Take doravirine exactly as prescribed by your healthcare provider. The typical dosage is one tablet (100 mg) once daily.
  • Timing: You can take doravirine with or without food. Choose a time that is convenient for you, and try to take it around the same time every day to maintain consistent levels of the medication in your bloodstream.
  • Swallowing: Swallow the tablet whole with a glass of water. Do not crush, chew, or break the tablet, as this can affect the way the medication is absorbed by your body.
  • Missed Dose: If you miss a dose of doravirine, take it as soon as you remember. However, if it’s almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not double up on doses to make up for a missed one.
  • Follow-up: Keep regular appointments with your healthcare provider while taking doravirine to monitor your progress and any potential side effects. Your provider may also perform blood tests to check your viral load and immune function.
  • Other Medications: If you are taking other medications, including over-the-counter drugs and supplements, inform your healthcare provider to avoid any potential interactions with doravirine.
  • Storage: Store doravirine tablets at room temperature away from moisture and heat. Keep the medication in its original packaging and out of reach of children.

Always consult your healthcare provider or pharmacist if you have any questions or concerns about how to use doravirine properly. They can provide personalized advice based on your medical history and individual needs.
