depression. The drug decreases the brain's sensitivity to co2, causing slow, shallow breathing or, in severe cases, total respiratory arrest. visit website is most likely to take place if the drug is administered too rapidly or in high doses. 2.

Tolerance: The body needs significantly greater doses to attain the same level of discomfort relief.

and Care Excellence(NICE)and the British National Formulary (BNF), state specific contraindications for fentanyl citrate. Table 2: Contraindications and Risk Factors Condition Threat Factor with Fentanyl Asthma/ COPD Increased danger of extreme respiratory failure. Head Injury May mask clinical signs of intracranial pressure modifications. Hypovolemia High danger of extreme hypotension(low blood pressure ). Myasthenia Gravis May worsen muscle weakness and breathing struggle. MAOIs( Antidepressants)Serious danger of hypertensive crisis or serotonin syndrome. Reporting Side Effects: The Yellow Card Scheme In the United Kingdom, the Medicines and Healthcare
products Regulatory Agency(MHRA)keeps an eye on the security of all medications. If a patient or healthcare expert observes an unanticipated or serious adverse effects from a fentanyl citrate injection, they are motivated to report it by means of the Yellow Card Scheme.
