More than 1,000 children and adults with colic experience relief within hours of taking Colace. The treatment is taken until the symptoms subside or a doctor determines they no longer need it. It’s advised to take the medication only as needed, but many people find that they can use smaller doses more frequently. Medications like this work best when used regularly, even if you only have mild stomach pain from time to time. This way your body will become accustomed to giving less signals for pain and won’t be as sensitive to irritation in the future. Always read the label before using any medication – including over-the-counter medications –and talk to your doctor before taking anything new for an upset tummy.
