How to Use morphine

Injectable solution

This medicine is for injection into a muscle, vein, or under the skin. It is usually given by a health care professional in a hospital or clinic setting.

If you get this medicine at home, you will be taught how to prepare and give this medicine. Use exactly as directed. Take your medicine at regular intervals. Do not take your medicine more often than directed.

Always look at your medicine before using it. Do not use the injection if its color is darker than pale yellow or if it is discolored in any other way. Do not use this medicine if it is cloudy, thickened, colored, or has solid particles in it.

It is important that you put your used needles and syringes in a special sharps container. Do not put them in a trash can. If you do not have a sharps container, call your pharmacist or healthcare provider to get one.

Talk to your pediatrician regarding the use of this medicine in children. Special care may be needed.

What should I tell my health care provider before I take this medicine?

They need to know if you have any of these conditions:

  • brain tumor
  • drug abuse or addiction
  • head injury
  • heart disease
  • if you often drink alcohol
  • liver disease
  • lung or breathing disease, like asthma
  • problems urinating
  • seizures
  • stomach or intestine problems
  • taken an MAOI like Carbex, Eldepryl, Marplan, Nardil, or Parnate in the last 14 days
  • an unusual or allergic reaction to morphine, other medications, foods, dyes, or preservatives
  • pregnant or trying to get pregnant
  • breast-feeding
What if I miss a dose?

If you miss a dose, take it as soon as you can. If it is almost time for your next dose, take only that dose. Do not take double or extra doses.

What should I watch for while using this medicine?

Tell your doctor or health care professional if your pain does not go away, if it gets worse, or if you have new or a different type of pain. You may develop tolerance to the medicine. Tolerance means that you will need a higher dose of the medicine for pain relief. Tolerance is normal and is expected if you take this medicine for a long time.

Do not suddenly stop taking your medicine because you may develop a severe reaction. Your body becomes used to the medicine. This does NOT mean you are addicted. Addiction is a behavior related to getting and using a drug for a non-medical reason. If you have pain, you have a medical reason to take pain medicine. Your doctor will tell you how much medicine to take. If your doctor wants you to stop the medicine, the dose will be slowly lowered over time to avoid any side effects.

There are different types of narcotic medicines (opiates). If you take more than one type at the same time or if you are taking another medicine that also causes drowsiness, you may have more side effects. Give your health care provider a list of all medicines you use. Your doctor will tell you how much medicine to take. Do not take more medicine than directed. Call emergency for help if you have problems breathing or unusual sleepiness.

You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medicine affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol may interfere with the effect of this medicine. Avoid alcoholic drinks.

This medicine will cause constipation. Try to have a bowel movement at least every 2 to 3 days. If you do not have a bowel movement for 3 days, call your doctor or health care professional.

Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water may help. Contact your doctor if the problem does not go away or is severe.

Where should I keep my medicine?

Keep out of the reach of children. This medicine can be abused. Keep it in a safe place to protect it from theft. Do not share this medicine with anyone. Selling or giving away this medicine is dangerous and is against the law.

If you are using this medicine at home, you will be instructed on how to store this medicine. Throw away any unused medicine after the expiration date on the label. Discard unused medicine and used packaging carefully. Pets and children can be harmed if they find used or lost packages.
