Is Metamucil safe during pregnancy?

What does the evidence say about Metamucil during pregnancy?

1. Over-the-counter laxatives at recommended doses are not expected to raise the chance of birth defects, and fiber or bulk products such as psyllium are one of the five categories reviewed. 1
2. Fiber-containing bulking agents such as Metamucil are described as probably the safest laxative option in pregnancy, with osmotic agents like polyethylene glycol used for longer-running constipation. 2
3. Fiber supplementation raised stool frequency by about 2.24 bowel movements per week in pregnancy trials, though the pooled evidence covered only 180 women across two studies. 3
4. Psyllium is the single fiber type meta-analyses back for constipation symptoms, at 7 to 30 grams a day, with roughly one in seven people seeing a benefit. 4
5. Swallowing psyllium without enough fluid has caused bowel obstruction in published cases, because the husk holds water and expands to many times its original size. 5

Is Metamucil safe in each trimester?

• First trimester. Constipation often shows up early, when rising progesterone slows the bowel and prenatal iron adds to the sluggishness. Fiber plus steady fluid across the day is usually where clinicians start.
• Second trimester. This is when constipation peaks for many people. If a daily dose has become routine, mention it at your next visit so your provider can look at the timing alongside your iron and other supplements.
• Third trimester. Psyllium stays a reasonable option late in pregnancy. Keep fluids high, since the bulking effect depends entirely on water, and flag cramping, several days without a bowel movement, or any bleeding.
