It is recommended to take XADAGO at the same time each day. Do not start or stop taking XADAGO without talking to your healthcare provider first.
The most common side effects seen with XADAGO are uncontrolled movements (dyskinesia), falls, nausea, and trouble sleeping or falling asleep (insomnia).
No, you do not have to change your diet. Restriction of foods and beverages is usually not required when treated with the recommended doses of XADAGO.

The combination of MAO-B inhibitors like XADAGO and antidepressants has resulted in a serious and sometimes fatal condition called serotonin syndrome.

Do not take XADAGO with opioid medications including meperidine, tramadol, methadone, or propoxyphene, as this could result in serious, sometimes fatal, reactions.

Also, do not take XADAGO with amphetamine, cyclobenzaprine, methylphenidate, or St. John’s wort. Taking these drugs together can also result in serotonin syndrome, which could be fatal.

Do not use XADAGO with dextromethorphan. The combination of MAO inhibitors and dextromethorphan has been reported to cause episodes of psychosis or abnormal behavior.
If a dose of once-daily XADAGO is missed, the next dose should be taken at the same time the next day.
