The correct dose for each person is determined by the doctor and is based on patient weight and body surface area. You’ll work with your healthcare team to find the best dose for you or your loved one.

Dosing envelope and packets not shown at actual size. A 5-g dosing envelope is shown as an example. OLPRUVA is available in a number of strengths, and your doctor will decide which dose is best for you.

To take or give 1 dose of OLPRUVA as prescribed, you will need:

1 dosage envelope containing OLPRUVA and Mix-Aid packets. The contents of 1 envelope equals 1 full dose

An open drinking cup

A spoon

8 ounces of water (4 ounces for mixing the OLPRUVA dose and 4 ounces for a “rinse” to ensure you get the full dose)

*Mix-Aid (100% modified food starch) is mixed with water to thicken the water and create a “suspension” for the medication.

Watch the administration video.

Here are the steps for preparing and taking or giving a dose of OLPRUVA:

Step 1: Get an open drinking cup and spoon.

Step 2: Add about 4 ounces of water to an open drinking cup.

Step 3: Remove 1 dosage envelope from the kit.

Note: Each kit is divided into 30 individual sections. Each section contains 3 dosage envelopes for a total of 90 dosage envelopes.

Step 4: Open the dosage envelope and remove all packets (1 packet of Mix-Aid and 1 or 2 packets of OLPRUVA).

Note: All packets in the dosage envelope must be used for 1 full dose.

Step 5: To open the Mix-Aid packet, tear or cut with scissors, straight across from the notch.

Step 6: Add the full contents of the Mix-Aid packet to the water (in the open drinking cup) and stir with the spoon for at least 30 seconds.

Note: The contents will not dissolve but will make the water thicker so that OLPRUVA does not sink to the bottom of the cup.

Do not drink yet.

Step 7: To open the OLPRUVA packet(s), fold at the notch and tear or cut with scissors. Add the full contents of the OLPRUVA packet(s) to the open drinking cup containing the mixture from Step 6 (the water and Mix-Aid) and stir for 15 seconds.

Drink the entire contents of the open drinking cup within 5 minutes to help prevent the coating from dissolving.

Note: The entire contents of each packet must be used for 1 full dose.

Step 8: To make sure that you get the full dose, pour another 4 ounces of water in the open drinking cup, stir, and drink the entire contents.

Do not take or give OLPRUVA suspension in a gastrostomy or nasogastric tube.

The mixed OLPRUVA suspension should be thrown away (discarded) after 30 minutes, if not used right away.

Take your OLPRUVA dose with food. If you miss a dose of OLPRUVA, take it as soon as possible that same day.
