For these people and situations
Product overview
“Colac Suppository Type” is a fast-acting constipation suppository from the Colac series manufactured and sold by Taisho Pharmaceutical. The suppository quickly melts at body temperature and reacts with mucus in the rectum to generate fine spherical carbon dioxide gas, which acts on the rectum to gently promote bowel movement. Because the carbon dioxide acts locally only in the rectum, it is characterized by a gentle effect that is less likely to cause abdominal pain.
Oral laxatives usually take about 6 to 11 hours to work, but this medicine works quickly in about 10 to 30 minutes after use. It can be used in a wide range of situations such as sudden constipation during travel or before going out, for those who dislike oral medication, or those who resist enemas. It is a Class 3 OTC Drug usable from age 12.
Product features
Fast-acting: effects appear in about 10 to 30 minutes
Effect expected within 10 to 30 minutes after useOral laxatives take time to reach the intestines, but Colac suppository type is inserted directly into the rectum, so fast action of about 10 to 30 minutes can be expected (individual differences apply). Suitable for urgent situations like travel or before going out.
Carbon dioxide acts only on the rectum
Local action, less likely to cause abdominal painThe suppository quickly melts at body temperature and reacts with mucus to generate fine spherical carbon dioxide gas. The carbon dioxide acts locally only in the rectum to promote bowel movement, making it less likely to cause abdominal pain compared to stimulant ingredients like bisacodyl that stimulate the entire intestine.
Easy to use as an alternative to enemas
Recommended for those who dislike enemasMany people feel resistance to enemas because they involve injecting liquid, but this medicine only requires inserting a solid suppository. The simple operation of inserting while sitting and then standing makes it easy to use for those who already use enemas or dislike them.
Suitable for breastfeeding and pregnant women (consultation required)
Confirmed by Taisho Pharmaceutical official FAQAccording to Taisho Pharmaceutical's official FAQ, Colac suppository type can be used by breastfeeding women. It is also recommended for pregnant women using laxatives. However, pregnant women must consult their primary care physician beforehand.
