Morphine has a high risk for abuse and severe, possibly fatal, breathing problems. The risk for harm is higher if you use the wrong dose/strength, or if you use it along with other drugs that might also affect breathing. Be sure you know how to use morphine and what other drugs you should avoid taking with it. The risk for breathing problems might also be higher when you start this medication and after a dose increase. Get immediate help if you notice unusual slow/shallow breathing.

Preservative-free morphine may also be given by a doctor as an injection into the area around the spinal cord (epidural) or into the fluid-filled space that contains the spinal cord (intrathecal). In this case, the medication is first given in the hospital where you can be monitored closely. If your doctor directs you to continue using this medication at home, it is usually given as a continuous injection using an infusion pump placed under your skin.
The dosage is based on your medical condition and response to treatment. For children, the dosage may also be based on weight. Do not increase your dose, use the medication more frequently, or use it for a longer time than prescribed. Properly stop the medication when so directed.
Pain medications work best if they are used when the first signs of pain occur. If you wait until the pain has worsened, the medication may not work as well.
Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Before injecting each dose, clean the injection site with rubbing alcohol.
