Metamucil is a fiber laxative medication used to treat occasional constipation. This medication may also help lower cholesterol when combined with a special diet.

Psyllium traps water in your intestinal tract to help make bowel movements easier. As it interacts with your intestinal tract, Metamucil may also improve microbial properties, which further help improve bowel movements and health.

This medication usually helps relieve constipation and produce bowel movements within 12 to 72 hours after taking the powder.

Uses and Dosage

Take Metamucil as directed by your doctor and read the label closely.

  • Mix powder into at least 8 ounces of liquid
  • Drink the mixture right away
  • Make sure you take Metamucil with enough water to avoid choking
  • Add more water to your glass afterwards, swirl, and drink right away
  • Metamucil should produce a bowel movement within 12 to 72 hours
  • Store at room temperature away from moisture and heat
  • Keep the container closed tight

Side Effects

Metamucil may cause some side effects while it interacts with your intestinal tract to relieve constipation. Consult with your doctor for more information regarding any symptoms you may encounter when taking this fiber laxative.

Common Metamucil side effects:

  • Bloating
  • Minor change in bowel habits

Serious Side Effects

Some more serious side effects may occur when taking Metamucil. Stop using and contact your doctor immediately if you notice any of the following symptoms:

  • Constipation lasting longer than 7 days

  • Severe stomach pain

Allergic reactions

Do not take Metamucil if you have ever had an allergic reaction to the medication. Stop using Metamucil and talk to your doctor if you notice any signs of an allergic reaction.

Metamucil allergy symptoms may include:

  • Hives
  • Difficulty breathing
  • Swelling of face, lips, tongue, or throat


If you don’t take Metamucil without enough water, it could swell in your throat and cause you to choke.

Avoid breathing in the Metamucil powder while you mix. Inhaling the dust could cause an allergic reaction.

If you use Metamucil as a cholesterol-lowering treatment, avoid foods high in fat or cholesterol to ensure your treatment plan functions its best.

Consult with your doctor over the safety of taking Metamucil if you have ever had any of the following:

  • Stomach pain, nausea, or vomiting
  • Trouble swallowing
  • A sudden change in bowel habits that lasts more than 2 weeks

Metamucil may affect your body’s ability to absorb other oral medications which could make them less effective. To avoid this, take Metamucil two hours before or after other oral medications.

Some drugs may interact with Metamucil and cause unwanted side effects or decrease its effectiveness. Tell your doctor about all medications you take, including vitamins and herbal products.

If you have diabetes, high blood pressure, phenylketonuria, or if you follow a low-salt diet, check the ingredient label closely because the Metamucil powder may contain sugar, sodium, or phenylalanine. Consult with your doctor for a catered treatment plan.

Ask your doctor about using Metamucil while pregnant or breastfeeding; you may need to take an adjusted dose.

Do not give this medication to a child younger than 6 without your doctor’s advice.

What to do for bloating while taking Metamucil?

A common side effect of taking Metamucil is bloating. If you are a new user, you can start by taking a smaller dose to allow your body to adjust. If this doesn’t help, you can speak with your doctor to make a plan of action.

What is the difference between Metamucil and MiraLAX?

Metamucil contains psyllium which is a natural plant fiber that encourages bowel movements by absorbing water and softening your stool. This medication can be used daily for occasional constipation. MiraLAX draws fluid into your colon using polyethylene glycol to soften stools and shouldn’t be used longer than 7 days.
