BRIVIACT Injection Dosage

BRIVIACT injection may be used when oral administration is temporarily not feasible [see Dosage and Administration (2.3)]. BRIVIACT injection should be administered intravenously at the same dosage and same frequency as BRIVIACT tablets and oral solution.

The clinical study experience with BRIVIACT injection is up to 4 consecutive days of treatment.

Administration Instructions for BRIVIACT Tablets and BRIVIACT Oral Solution

BRIVIACT can be initiated with either intravenous or oral administration.

BRIVIACT tablets and oral solution may be taken with or without food.

BRIVIACT Tablets

BRIVIACT tablets should be swallowed whole with liquid. BRIVIACT tablets should not be chewed or crushed.

BRIVIACT Oral Solution

A calibrated measuring device is recommended to measure and deliver the prescribed dose accurately. A household teaspoon or tablespoon is not an adequate measuring device.

When using BRIVIACT oral solution, no dilution is necessary. BRIVIACT oral solution may also be administered using a nasogastric tube or gastrostomy tube.

Discard any unused BRIVIACT oral solution remaining after 5 months of first opening the bottle.
