Potential for increased risk of cariprazine adverse effects
If starting cariprazine in a patient on a protease inhibitor, administer cariprazine 1.5 mg on Day 1 and Day 3, with no dose given on Day 2. From Day 4 onward, administer cariprazine 1.5 mg daily. Dose may be increased to a maximum of cariprazine 3 mg daily. If starting a protease inhibitor for a patient already taking cariprazine 3-6mg, reduce dose by half. For patients taking cariprazine 4.5 mg daily, reduced cariprazine dose to 1.5 - 3 mg daily. For patients taking cariprazine 1.5 mg daily, reduce to cariprazine 1.5 mg every other day. If PI is withdrawn, cariprazine dose may need to be increased.
