Treatment for ADR:
- Use diluted acetylcystein solution can decrease the probability of vomiting due to the medicine
- Treat systemic anaphylaxis reactions immediately by injecting under the skin adrenalin (0.3 – 0.5 ml of 1/1000 solution), breath 100% oxygen, set up endotracheal if needed, inject IV fluids to increase serum volume, inhale beta – adrenalin in case of bronchospasm, inject into veins 500 mg hydrocortisone or 125 mg methylprednisolone.
