Fentanyl citrate oral transmucosal and Sildenafil Intravenous
Determining the interaction of Fentanyl citrate oral transmucosal and Sildenafil Intravenous and the possibility of their joint administration.
In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.
Consumer:Limited evidence suggests that use of narcotic medications like fentaNYL may increase the effects of sildenafil. Rarely, there have been reports of prolonged erections lasting 2 to 5 hours. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Professional:MONITOR: Acute intake of opiates during sildenafil use may result in prolonged erections. The proposed mechanism is an opiate-induced acute increase in cyclic guanosine monophosphate concentrations in peripheral nerve endings, which can be additive with that produced by sildenafil. The interaction has been reported specifically with dihydrocodeine but could conceivably occur with other opiates. In two patients who had been using sildenafil for erectile dysfunction, prolonged erections lasting 2 to 5 hours occurred on several occasions of sildenafil use within the first week after initiation of treatment with dihydrocodeine. One patient discontinued the dihydrocodeine, whereupon his erections from sildenafil returned to normal. The other patient continued taking dihydrocodeine for an additional 2 weeks but had no further problems.
MANAGEMENT: Patients using sildenafil should be advised of the potential for prolonged erections during acute intake of opiates, and to contact their physician if problems occur. The interaction may not occur during chronic use of opiates.
