By imitating the action of naturally taking place endorphins, it hinders the transmission of discomfort signals and changes the understanding of discomfort.

Severe and Life-Threatening Side Effects
While mild adverse effects can be handled, specific reactions need immediate medical intervention. In a hospital setting, patients are kept track of through pulse oximetry and ECG to detect these problems early.
1. Breathing Depression
The most unsafe negative effects of fentanyl is its ability to minimize the drive to breathe. If the dosage is too expensive or administered too quickly, the patient's breathing may become shallow or stop totally (apnoea).

2. Skeletal Muscle Rigidity
Fentanyl can cause "wooden chest syndrome," a condition where the muscles of the chest wall and abdominal area end up being stiff. This makes manual ventilation hard and requires treatment with muscle relaxants or opioid villains like Naloxone.
3. Anaphylaxis and Hypersensitivity
Though unusual, some people might have an allergic reaction to fentanyl citrate. Indications include:

- Individuals with Respiratory Conditions: Those with asthma, sleep apnoea, or weight problems may experience more extreme breathing anxiety.
- Head Injury Patients: Fentanyl can increase intracranial pressure and obscure the medical course of a head injury.

Long-lasting Considerations: Dependence and Tolerance
While fentanyl citrate injection is frequently utilized for short-term sharp pain, its use in chronic pain management (though less common via injection) brings dangers of physical dependence and addiction.
- Tolerance: Over time, the body needs greater doses to achieve the same pain-relieving result.
