Oxycodone Teva (Oxycodone Hydrochloride)

Oxycodone Teva is an opioid analgesic that acts on the central nervous system to relieve pain.

• Acute postoperative pain: Provides effective relief of pain following surgical procedures.
• Cancer‑related pain: Helps manage persistent pain associated with malignant disease.
• Severe chronic non‑cancer pain: Reduces intensity of long‑term pain when other analgesics are insufficient.

• Oxycodone binds to mu‑opioid receptors in the central nervous system, activating inhibitory G‑protein pathways that decrease neuronal excitability and reduce the perception of pain. This receptor activation also modulates neurotransmitter release, contributing to its analgesic effect.

Adverse reactions to oxycodone may vary in frequency and severity.

Common Side Effects

• Nausea: Feeling of stomach upset or urge to vomit.
• Constipation: Reduced bowel movements and hard stools.
• Drowsiness: Increased sleepiness or fatigue.
• Dry mouth: Reduced salivation leading to a parched feeling.
• Dizziness: Light‑headed sensation, especially when standing quickly.
• Itching: Mild skin irritation or pruritus.

Serious or Rare Side Effects

• Respiratory depression: Slowed or shallow breathing that can be life‑threatening.
• Severe hypotension: Markedly low blood pressure causing faintness.
• Seizures: Uncontrolled electrical activity in the brain.
• Allergic reactions: Rash, swelling, or anaphylaxis.
• Dependence and withdrawal: Physical and psychological reliance with withdrawal symptoms on abrupt discontinuation.

When prescribing oxycodone, clinicians should assess patient history and monitor for adverse outcomes.

• Assess risk of addiction: Evaluate personal or family history of substance misuse.
• Monitor respiratory function: Observe for signs of slowed breathing, especially after dose changes.
• Adjust for renal/hepatic impairment: Dose may need modification in patients with liver or kidney disease.
• Avoid concurrent CNS depressants: Limit use with alcohol, benzodiazepines, or other sedatives.
• Educate on constipation management: Recommend diet, fluids, and laxatives as needed.
• Store at ambient temperature: Keep below 25°C in the original packaging, protected from moisture.

Oxycodone may interact with several medication classes, altering its efficacy or safety profile.

Major Interactions (Avoid)

• Combined with other opioids: Increases risk of respiratory depression and profound sedation.
• Concurrent use with benzodiazepines: Heightens potential for severe respiratory depression.
• MAO inhibitors: May precipitate hypertensive crisis or serotonin syndrome.

Moderate Interactions (Monitor Closely)

• CNS depressants (e.g., antihistamines, muscle relaxants): May enhance drowsiness.
• CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): Can raise oxycodone plasma levels.
• CYP3A4 inducers (e.g., rifampicin, carbamazepine): May reduce analgesic effect.
