Treatment with a daily dose above 5 mg has not been studied.
Delayed or missed doses: If a planned dose is missed, it should be administered as soon as possible if still within 6 hours of the scheduled dose. Otherwise, the missed dose should be skipped and the next dose should be administered at the regularly scheduled time the next day.
If a dose is not fully swallowed or vomiting occurs after taking a dose of Evrysdi, another dose should not be administered to make up for the incomplete dose. The next dose should be administered at the regularly scheduled time.
Elderly: No dose adjustment is required in elderly patients based on limited data in subjects aged 65 years and older (see Pharmacology: Pharmacokinetics under Actions).
Renal impairment: Risdiplam has not been studied in this population. No dose adjustment is expected to be required in patients with renal impairment (see Pharmacology: Pharmacokinetics under Actions).
Hepatic impairment: No dose adjustment is required in patients with mild or moderate hepatic impairment. Patients with severe hepatic impairment have not been studied and may have increased risdiplam exposure (see Pharmacology: Pharmacodynamics and Pharmacokinetics under Actions).
Paediatric population: The safety and efficacy of risdiplam in paediatric patients < 2 months of age have not yet been established (see Pharmacology: Pharmacodynamics under Actions). No data are available.
Method of administration: Oral use.
Evrysdi must be constituted by a healthcare professional (HCP) prior to being dispensed.
It is recommended a HCP discuss with the patient or caregiver how to prepare the prescribed daily dose prior to administration of the first dose.
Evrysdi is taken orally once a day after a meal at approximately the same time each day, using the re-usable oral syringe provided. In infants who are breastfed, Evrysdi should be administered after breastfeeding. Evrysdi should not be mixed with milk or formula milk.
Evrysdi should be taken immediately after it is drawn up into the oral syringe. If it is not taken within 5 minutes, it should be discarded from the oral syringe and a new dose be prepared. If Evrysdi spills or gets on the skin, the area should be washed with soap and water.
The patient should drink water after taking Evrysdi to ensure the medicinal product has been completely swallowed. If the patient is unable to swallow and has a nasogastric or gastrostomy tube in situ, Evrysdi can be administered via the tube. The tube should be flushed with water after delivering Evrysdi. (See Table 4.)
