Morphine Sulfate

Morphine sulfate is a highly potent opioid analgesic. It acts directly on the central nervous system to relieve severe pain. Due to severe risks of addiction, abuse, misuse, and life-threatening respiratory depression, it is classified as a Schedule II controlled substance.

Dosage by Body Weight

Dosages must be highly individualized. For pediatric patients, dosing is strictly based on weight (typically 0.15 to 0.3 mg/kg orally or 0.05 to 0.1 mg/kg intravenously/intramuscularly) and must be calculated and administered by a qualified healthcare provider. Do not use without professional medical supervision.
