Before prescribing a dosage of Fanapt, your healthcare provider will consider several factors, such as other medications you are taking and other medical conditions you have. Fanapt is typically started at a low dosage and then slowly increased, in order to reduce the risk of orthostatic hypotension. The medication comes in tablet form and is usually taken twice a day.
Fanapt Dosage: An IntroductionThe dose of Fanapt® (iloperidone) your healthcare provider recommends will vary, depending on a number of factors, including:
- How you respond to Fanapt
- Other medications you are taking
- Other medical conditions you may have.
As is always the case, do not adjust your dosage unless your healthcare provider specifically instructs you to do so.
Fanapt Dosing for SchizophreniaIn order to reduce the risk of low blood pressure when standing up too quickly (known as orthostatic hypotension), Fanapt is started at a low dose and slowly increased. The standard recommended dosing for Fanapt is as follows:
- Day 1 -- Fanapt 1 mg twice daily
- Day 2 -- Fanapt 2 mg twice daily
- Day 3 -- Fanapt 4 mg twice daily
- Day 4 -- Fanapt 6 mg twice daily
- Day 5 -- Fanapt 8 mg twice daily
- Day 6 -- Fanapt 10 mg twice daily
- Day 7 -- Fanapt 12 mg twice daily.
Some people may not need the maximum Fanapt dosage. If you have stopped taking Fanapt for more than three days, it is usually recommended that you start back with a low dose and increase the dosage slowly (as was done initially).
If you take certain other medications, the recommended dosage is reduced by half (see Fanapt Drug Interactions for more information). Similarly, if you are known to metabolize certain medications more slowly than normal (laboratory tests have shown that you are a "CYP 2D6 poor metabolizer"), the recommended dosage is reduced by half.
