Tolerance: The body needs significantly greater dosages to achieve


• the very same level of discomfort relief. Reliance: The body becomes accustomed to the presence of

  the opioid, leading to withdrawal signs if the medication is

• and Care Excellence(NICE)and the British National Formulary (BNF), stipulate particular contraindications for fentanyl citrate. Table 2: Contraindications and Risk Factors


• Condition Danger Factor with Fentanyl Asthma/ COPD Increased danger of serious breathing failure. Head Injury May mask scientific indications



of intracranial pressure changes. Hypovolemia High threat

of severe hypotension(low high blood pressure ). Myasthenia Gravis May worsen muscle weakness and respiratory battle. 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
