This dosage information does not include all the information needed to use Stadol safely and effectively. See full prescribing information for Stadol.
The information at Drugs.com is not a substitute for medical advice. ALWAYS consult your doctor or pharmacist.
Factors to be considered in determining the dose are age, body weight, physical status, underlying pathological condition, use of other drugs, type of anesthesia to be used, and surgical procedure involved. Use in the elderly, in patients with hepatic or renal disease, or in labor requires extra caution (see PRECAUTIONS and CLINICAL PHARMACOLOGY: Individualization of Dosage). The following doses are for patients who do not have impaired hepatic or renal function and who are not on CNS active agents.
Use for Pain
Intravenous: The usual recommended single dose for IV administration is 1 mg repeated every 3 to 4 hours as necessary. The effective dosage range, depending on the severity of pain, is 0.5 to 2 mg repeated every 3 to 4 hours.
Intramuscular: The usual recommended single dose for IM administration is 2 mg in patients who will be able to remain recumbent, in the event drowsiness or dizziness occurs. This may be repeated every 3 to 4 hours, as necessary. The effective dosage range depending on the severity of pain is 1 to 4 mg repeated every 3 to 4 hours. There are insufficient clinical data to recommend single doses above 4 mg.
The usual recommended dose for initial nasal administration is 1 mg (1 spray in one nostril). Adherence to this dose reduces the incidence of drowsiness and dizziness. If adequate pain relief is not achieved within 60–90 minutes, an additional 1-mg dose may be given.
The initial dose sequence outlined above may be repeated in 3–4 hours as required after the second dose of the sequence.
Depending on the severity of the pain, an initial dose of 2 mg (1 spray in each nostril) may be used in patients who will be able to remain recumbent in the event drowsiness or dizziness occurs. In such patients single additional 2-mg doses should not be given for 3–4 hours.
Use as Preoperative/Preanesthetic Medication
The preoperative medication dosage of STADOL Injection should be individualized (see CLINICAL PHARMACOLOGY: Individualization of Dosage). The usual adult dose is 2 mg IM, administered 60–90 minutes before surgery. This is approximately equivalent in sedative effect to 10 mg morphine or 80 mg meperidine.
Use in Balanced Anesthesia
The usual dose of STADOL Injection is 2 mg IV shortly before induction and/or 0.5 to 1.0 mg IV in increments during anesthesia. The increment may be higher, up to 0.06 mg/kg (4 mg/70 kg), depending on previous sedative, analgesic, and hypnotic drugs administered. The total dose of STADOL Injection will vary; however, patients seldom require less than 4 mg or more than 12.5 mg (approximately 0.06 to 0.18 mg/kg).
The use of STADOL NS is not recommended because it has not been studied in induction or maintenance of anesthesia.
In patients at full term in early labor a 1–2 mg dose of STADOL Injection IV or IM may be administered and repeated after 4 hours. Alternative analgesia should be used for pain associated with delivery or if delivery is expected to occur within 4 hours.
If concomitant use of STADOL with drugs that may potentiate its effects is deemed necessary (see PRECAUTIONS: Drug Interactions), the lowest effective dose should be employed.
The use of STADOL NS is not recommended as it has not been studied in labor.
Safety and Handling
STADOL Injection is supplied in sealed delivery systems that have a low risk of accidental exposure to health care workers. Ordinary care should be taken to avoid aerosol generation while preparing a syringe for use. Following skin contact, rinsing with cool water is recommended.
STADOL NS is an open delivery system with increased risk of exposure to health care workers.
In the priming process, a certain amount of butorphanol may be aerosolized; therefore, the pump sprayer should be aimed away from the patient or other people or animals.
The disposal of Schedule IV controlled substances must be consistent with State and Federal Regulations. The unit should be disposed of by unscrewing the cap, rinsing the bottle, and placing the parts in a waste container.
