Morphine Sulfate While Pregnant: What You Need to Know

Morphine sulfate is derived from a source inside the poppy straw of the opium poppy flower. morphine sulfate is an opioid analgesic, which is used to change the way your body feels and responds to pain. It can be prescribed for acute pain or chronic pain and is highly addictive. Morphine sulfate works by affecting certain receptors in the central nervous system, changing the way you perceive pain.

It’s not completely known how safe it is to take morphine sulfate while pregnant, as there have been no human studies. Data collected shows there may be some risk to your unborn baby, but the effects are largely reversible.

Morphine sulfate may be prescribed if the benefit to the mother outweighs the risks to her baby. Work with your doctor and ask him if taking morphine while pregnant is the best way to manage your pain.

As with any other prescription drug, morphine sulfate carries a risk of side effects. These side effects can include:

  1. Nausea
  2. Vomiting
  3. Constipation
  4. Lightheadedness
  5. Dizziness
  6. Drowsiness
  7. Sweating

Serious side effects can also occur including mental/mood changes, severe stomach pain, difficulty urinating, loss of appetite, unusual tiredness, and weight loss. If you experience any side effects, contact your doctor right away, as some may be serious. He will help you decide if morphine sulfate is the right choice to handle your pain.

Morphine sulfate is listed under the Controlled Substance Act in the United States as a Schedule II controlled substance. Schedule II controlled substances have a high potential for addiction and abuse. Refills of prescription drugs on this list are not allowed, and only a doctor who is licensed to prescribe opiates can prescribe morphine sulfate.

Babies born to mothers taking morphine sulfate may have developed a dependency on the prescription and may experience withdrawal. This is known as neonatal opioid withdrawal syndrome. If this syndrome is not recognized and treated right away, it can be life-threatening to the baby. Symptoms of neonatal opioid withdrawal include tremors, irritability, sleeping problems, high-pitched crying, tight muscle tone, hyperactive reflexes, seizures, yawning, stuffy nose, sneezing, poor feeding and suck, vomiting, diarrhea, dehydration, sweating, fever, and unstable temperature. Be sure to let your baby’s doctor know right away if these symptoms become apparent in your newborn.

Prolonged use of morphine sulfate while pregnant may also cause your baby respiratory depression.

Morphine Sulfate While Pregnant: What You Need to Know

When evaluating a medication’s safety for pregnant women, the FDA (Food and Drug Administration) rates each medicine on a scale of A, B, C, D, or X. Morphine sulfate has been listed as C on the safety scale for pregnant women, which means there are possible risks to the baby. There are risks, as the FDA has acknowledged animal studies have shown adverse effects of Morphine on the fetus but there are no well-controlled human studies to confirm these findings. Because of this lack of research, you should only use Morphine while pregnant if it is absolutely necessary.

These risks are thought to be more physiological without causing malformations to the fetus. As mentioned, these are largely reversible.

Only use morphine sulfate while pregnant if necessary because whatever prescription a mother takes, so does her unborn child.

If you are currently struggling with a morphine addiction and become pregnant, you should seek help as soon as possible. The Recovery Village can provide you with treatment programs to help you live a happier, healthier, substance-free life. You can choose from either inpatient or outpatient morphine rehab to help get you clean. Inpatient morphine rehab requires that patients live at one of The Recovery Village’s designated inpatient centers while going to therapy. Outpatient rehab, usually reserved for more mild cases of morphine addiction, allows patients to live at home while they attend their therapy session at The Recovery Village. You may also want to seek a medically assisted detoxification program before entering morphine rehab. This type of program allows patients to safely detox from morphine in the presence of medically trained staff. These staffers will be able to answer any questions you may have about managing morphine withdrawal and the general recovery process. Recovery is important, especially if you are pregnant, as the health of the fetus depends on you getting clean. In addition, you will want to be a good role model for your child as they grow up, and this will require getting clean from morphine addiction. Ongoing therapy may also be a good idea, as this form of therapy can keep you sober after the initial morphine rehab treatment.
