Precautions and Warnings With Morphine Sulfate

Specific Morphine Sulfate Precautions and Warnings

Some warnings and precautions to be aware of prior to taking morphine sulfate include the following:
  • Morphine sulfate is a narcotic medication with significant potential for abuse. It is not a good choice for people who have a history of alcohol or drug abuse (see Morphine Addiction). Do not take the drug more frequently, longer, or at a higher dose than prescribed. If you feel you may be developing a problem with morphine sulfate, please seek help from your healthcare provider.
  • Like any other narcotic, morphine sulfate can cause dizziness and drowsiness, and may increase the risk of falls in elderly people.
  • Do not drive or operate heavy machinery until you know how morphine sulfate affects you. Your reflexes and reaction times may be significantly affected, even if you feel fine.
  • Morphine sulfate can cause slow and irregular breathing, especially at high doses. In severe situations, this may lead to life-threatening complications. This may be especially dangerous in people with lung problems.
  • This medication can cause problems in people with head injuries or high intracranial pressure. Morphine sulfate should only be used with extreme caution in such circumstances.
  • Morphine sulfate can interfere with the diagnosis of many conditions that cause severe abdominal (stomach) pain.
  • Check with your healthcare provider before taking the drug if you have hypothyroidism, Addison's disease, an enlarged prostate, or kidney disease, as morphine sulfate may not be the best choice for you.
  • Narcotics such as morphine sulfate are likely to cause constipation. This side effect does not go away as you continue to take the drug. Usually, laxatives are necessary to treat and prevent constipation due to morphine sulfate (see Morphine and Constipation).
  • Morphine sulfate can potentially interact with several other medications (see Drug Interactions With Morphine Sulfate).
  • Morphine sulfate is considered a pregnancy Category C medication. This means that it may not be safe for use during pregnancy, although the full risks are not known (see Morphine and Pregnancy).
  • Morphine sulfate passes through breast milk. Therefore, if you are breastfeeding or plan to start breastfeeding, discuss this with your healthcare provider prior to taking the drug (see Morphine and Breastfeeding).
