Hydromorphone Kalceks is a strong opioid pain medicine used to treat severe pain in adults and young people over 12 years old.
For adults and young people over 12: typically 1–1.5 mg into a vein over 2–3 minutes, repeated every 3–4 hours; or 1–2 mg under the skin, repeated every 3–4 hours. As an infusion into a vein or under the skin, typical starting dose is 0.15–0.45 mg per hour. For patient-controlled pain relief (PCA), the recommended bolus dose is 0.2 mg with a 5–10 minute lockout.
This medicine is given as an injection into a vein (intravenously) or under the skin (subcutaneously), or as a slow drip (infusion), by a doctor or nurse.
Your doctor will decide your maximum daily dose based on your pain, previous pain medications, age, and weight, and will adjust it until your pain is relieved.
