Is It Safe to Take Dulcolax or Colace While Pregnant?

Constipation is acommon symptom of pregnancy. Oftentimes, OTC medications are needed for relief.

Dulcolax and Colace will not cross the placenta to affect the fetus if used during pregnancy. Therefore, they are generally considered safe to use while pregnant. However, Dulcolax use should be as limited as possible due to the risk of side effects such as electrolyte imbalances. It’s typically recommended to use other products before Dulcolax in pregnancy.

Don’t take Dulcolax within one hour of drinking milk or taking heartburn medications. This can cause the outer coating of the pills to dissolve too soon, reducing its effectiveness.

Some of theseheartburn medicationsmay include:

Dulcolax vs. Colace: Which One Should I Choose?

Both medications are effective in relieving constipation. However, Dulcolax may begin working within a few hours, whereas Colace may take one to three days to see an improvement.

For this reason, you may opt for Dulcolax if you’re looking for quick relief for your constipation symptoms. On the other hand, if you need a longer-term solution, Colace may be a better option.

It is important to discuss all health conditions and current medications with a healthcare provider when discussing which treatment is right for you.

Summary

Both Dulcolax and Colace are formulated to help reduce symptoms of constipation. However, their side effects, their time to take effect, and the types of dosage forms they come in differ. Dulcolax and Colace also work differently; Dulcolax is considered a stimulant laxative, while Colace is a stool softener.

If laxatives don’t help your symptoms, or you experience frequent constipation, talk to a healthcare provider about other treatment options.
