Constipation
"This product is strong. I mean STRONG. I only use it as a last resort when other, gentler remedies fail. I never need to take more than one pill, even though the box suggests up to 3. And I only take it if I expect to be near a bathroom for the entirety of the next day, because the laxative effect lasts about 24 hours. I make sure to drink plenty of water (or one of those sports/electrolyte drinks) to avoid dehydration. The only side effect I&#039;ve noticed is chills. Many of the pink &quot;women&#039;s laxatives&quot; contain the exact same active ingredient as Dulcolax, so if you&#039;re avoiding one, check the labels very carefully before you buy the other."
