ओलैंज़ापिन और फ्लुओक्सेटिन और रिस्पेरिडोन का इंटरैक्शन

Fluoxetine and paroxetine increase plasma concentrations of risperidone.

When either concomitant fluoxetine or paroxetine is initiated or discontinued, the physician should re-evaluate the dose of RISPERDAL CONSTA.

When initiation of fluoxetine or paroxetine is considered, patients may be placed on a lower dose of RISPERDAL CONSTA between 2 to 4 weeks before the planned start of fluoxetine or paroxetine therapy to adjust for the expected increase in plasma concentrations of risperidone.

When fluoxetine or paroxetine is initiated in patients receiving the recommended dose of 25 mg RISPERDAL CONSTA, it is recommended to continue treatment with the 25-mg dose unless clinical judgment necessitates lowering the RISPERDAL CONSTA dose to 12.5 mg or necessitates interruption of RISPERDAL CONSTA treatment.

When RISPERDAL CONSTA is initiated in patients already receiving fluoxetine or paroxetine, a starting dose of 12.5 mg can be considered.
