Your healthcare provider will recommend a starting Avinza dosage based on several factors, including the dose and type of painkillers you were previously taking. If you are switching from another oral form of morphine, a straight mg-per-mg conversion is recommended. For injected morphine or any non-morphine painkillers, your healthcare provider will need to convert your dosage. The maximum daily Avinza dose is 1600 mg.
The dose of Avinza® (morphine sulfate ER) that your healthcare provider recommends will vary, depending on a number of factors, including:
- The type and severity of your pain
- How you respond to Avinza
- The type and dose of other painkillers you have taken
- Other medications you are taking
- Other medical conditions you may have.
As is always the case with any medication, do not adjust your dosage unless your healthcare provider specifically instructs you to do so.
In most cases, the starting dose of Avinza that your healthcare provider recommends will depend mostly on the dose and type of painkillers you were previously taking. If you are switching from another oral form of morphine, a straight mg-per-mg conversion is recommended. Simply add up the total mg of morphine you take per day; this is the recommended Avinza dose, taken as a single dose per day. For instance, if you are switching from 10 mg of morphine nine times a day, the recommended Avinza dosage is 90 mg once daily.
For injected morphine or any non-morphine painkillers, your healthcare provider will need to convert your current dosage to an appropriate Avinza dosage. It is best to underestimate (rather than overestimate) the dose initially, in order to avoid dangerous Avinza side effects.
