Risperidone

Risperdal

Use with caution

Your body turns risperidone into its active form faster than usual, and it is more likely not to work well for you. Your doctor may choose a different drug or adjust the dose carefully.

The genes behind this label

The guidelines read one gene for risperidone. Each card shows the two copies this person inherited and what they mean.

CYP2D6Your two copies: *2/*2x2

Ultrarapid metabolizer

One copy works normally and one works faster than usual.

3.0 activity scoreTypical: 1.25 to 2.25

Turns on or clears about 1 in 4 prescription drugs. These include many drugs for depression, pain and ADHD.

What the guidelines say

What each guideline says about your result.

CYP2D6Ultrarapid metabolizer

In plain words
Your body turns risperidone into its active form faster than usual, and it is more likely not to work well for you. Your doctor may choose a different drug or adjust the dose carefully.
What it means
Increased CYP2D6 activity raises the ratio of the active metabolite (9-hydroxyrisperidone, or paliperidone) to risperidone. The share of patients with therapy failure rises from 16% to 37%.
What the guideline suggests
Choose an alternative or titrate the dose according to the maximum dose for the active metabolite (paliperidone) (oral 12 mg/day for adults and children from 15 years of age weighing at least 51 kg and 6 mg/day for children from 15 years of age weighing less than 51 kg; intramuscular 75 mg per 2 weeks).
