Morphine Sulfate Information
(mor' feen)Morphine may increase the risk that you will experience breathing problems or other serious or life-threatening breathing problems, sedation, or coma if used along with certain medications. Tell your doctor if you are taking or plan to take any of the following medications: benzodiazepines such as alprazolam (Xanax), diazepam (Diastat, Valium), estazolam, flurazepam, lorazepam (Ativan), and triazolam (Halcion); medications for mental illness, nausea, or pain; muscle relaxants; sedatives; sleeping pills; or tranquilizers. Your doctor may need to change the dosages of your medications and will monitor you carefully. If you use morphine rectal with any of these medications and you develop any of the following symptoms, call your doctor immediately or seek emergency medical care: unusual dizziness, lightheadedness, extreme sleepiness, slowed or difficult breathing, or unresponsiveness. Be sure that your caregiver or family members know which symptoms may be serious so they can call the doctor or emergency medical care if you are unable to seek treatment on your own. Drinking alcohol, taking prescription or nonprescription medications that contain alcohol, or using street drugs during your treatment with morphine rectal increases the risk that you will experience these serious, life-threatening side effects. Do not drink alcohol, take prescription or nonprescription medications that contain alcohol, or use street drugs during your treatment. Morphine may be habit-forming. Do not use more of it, use it more often, or use it in a different way than directed by your doctor. Tell your doctor if you or anyone in your family drinks or has ever drunk large amounts of alcohol, uses or has ever used street drugs, or has overused prescription medications, or if you have or have ever had depression or another mental illness. There is a greater risk that you will overuse morphine if you have or have ever had any of these conditions. Talk to your doctor about the risks of using morphine rectal.
