Der skal udvises særlig forsigtighed under dosistitrering med Rapinyl hos patienter med kronisk obstruktiv lungesygdom eller andre medicinske tilstande, der prædisponerer dem for respirationsdepression (f. eks. myasthenia gravis), på grund af risikoen for yderligere respirationsdepression, der ville kunne medføre respirationssvigt.
Particular caution should be exercised during dose titration with Rapinyl in patients with chronic obstructive pulmonary disease or other medical conditions predisposing them to respiratory depression (e. g. myasthenia gravis) because of the risk of further respiratory depression, which could lead to respiratory failure.
