Precautions Before Use Synaleve

1. Medical History

  • Liver or Kidney Disease: Avoid Synaleve if you have severe liver or kidney impairments due to the risk of toxicity, especially from paracetamol.
  • Respiratory Conditions: Conditions such as asthma or chronic obstructive pulmonary disease (COPD) may be exacerbated by codeine, which can depress respiration.
  • Substance Abuse History: Codeine can be habit-forming; avoid in individuals with a history of addiction.

2. Pregnancy and Breastfeeding

  • Not recommended during pregnancy due to potential risks to the fetus, including respiratory depression.
  • Codeine passes into breast milk, potentially causing drowsiness or breathing difficulties in the infant.

3. Drug Interactions

  • Avoid combining Synaleve with:
    • Other CNS Depressants: Alcohol, sedatives, or tranquilizers can amplify drowsiness and respiratory depression.
    • Medications Containing Paracetamol: Increases the risk of liver damage due to cumulative doses.
    • Monoamine Oxidase Inhibitors (MAOIs): May result in dangerous interactions.

4. Driving and Machinery Operation

  • Avoid activities requiring alertness, as Synaleve may cause drowsiness, dizziness, or impaired coordination.
