How to use Delstrigo

Read the Patient Information Leaflet if available from your pharmacist before you start taking doravirine/lamivudine/tenofovir and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with or without food as directed by your doctor, usually once daily.

The dosage is based on other medications you may be taking. Be sure to tell your doctor and pharmacist about all the drugs you use (including prescription/nonprescription drugs and herbal products).

It is very important to keep taking this medication exactly as prescribed by your doctor. Do not skip any doses.

For the best effect, take this medication at evenly spaced times. To help you remember, take this medication at the same time every day.

Do not take more or less of this drug than prescribed or stop taking it even for a short time unless directed to do so by your doctor. Doing so may cause the amount of virus to increase, make the infection more difficult to treat (resistant), or worsen side effects.

Side Effects

Dizziness, drowsiness, nausea, trouble sleeping, or unusual dreams may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

As your immune system gets stronger, it can begin to fight off infections you already had, possibly causing disease symptoms to come back.
