FULL PRESCRIBING INFORMATION 1 INDICATIONS AND USAGE RYTARY is indicated for the treatment of Parkinson’s disease, post-encephalitic parkinsonism, and parkinsonism that may follow carbon monoxide intoxication or manganese intoxication. 2 DOSAGE AND ADMINISTRATION 2.1 Dosage in Patients Naïve to Levodopa Therapy The recommended starting dosage of RYTARY in levodopa-naïve patients is 48.75/195mg taken orally three times a day for the first 3 days. On the fourth day of treatment, the dosage of RYTARY may be increased to48.75/195mg taken three times a day. Based upon individual patient clinical response and tolerability, the RYTARY dose may be increased up to a maximum recommended dose of 48.75/195mg taken three times a day. The dosing frequency may be changed from three times a day to a maximum of five times a day if more frequent dosing is needed and if tolerated. Maintain patients on the lowest dosage required to achieve symptomatic control and to minimize adverse reactions such as dyskinesia and nausea. The maximum recommended daily dose of RYTARY is 48.75/195mg 2.2 Converting from Immediate-Release Carbidopa-Levodopa to RYTARY The dosages of other carbidopa and levodopa products are not interchangeable on a 1:1 basis with the dosages of RYTARY. To convert patients from immediate-release carbidopa-levodopa to RYTARY, first calculate the patient’s current total daily dose of levodopa. The starting total daily dose of RYTARY is as recommended in Table 1. After conversion, any combination of the four RYTARY dosage strengths can be used to achieve an optimal dosing. Adjust the dose and dosing frequency as necessary to maintain patient tolerance and sufficient symptomatic control. Administration of concomitant Parkinson’s disease medications should remain stable while adjusting the RYTARY dose. In clinical trials, RYTARY was administered in divided doses of three to five times a day. The maximum recommended total daily dose of RYTARY is 48.75/195mg For patients currently treated with carbidopa and levodopa plus a catechol-O-methyl transferase (COMT) inhibitor (such as entacapone), the initial total daily dose of levodopa in RYTARY described in Table 1 may need to be increased. Use of RYTARY in combination with other levodopa products has not been studied.
