Prokit may reduce the therapeutic effect of cabergoline (the active ingredient in Dostinex) by acting as an antagonist to dopamine receptors. In addition, Prokit affects the motility of the gastrointestinal tract, which may affect the absorption of concomitant oral drugs, so it is recommended to keep at least a 2-hour interval. The use of Medikinet with Dostinex and Prokit is not completely contraindicated, although caution is advised due to the possibility of interaction and aggravation of side effects of drugs. If the medicines have been prescribed by the same doctor, or if the prescriber has been informed about what other medicines you are already taking and what additional conditions you are suffering from, they may be used, but you should strictly follow the dosing regimen agreed with your doctor.
