So, your doctor recommended Duphalac syrup and now you have a few questions. What exactly is this stuff? How does it work? And most importantly, what can you expect after taking it? Don’t worry, we’ve got you covered. Duphalac is a laxative that works by softening your stools and stimulating bowel movements. It’s made of lactulose, a synthetic sugar, that can’t be digested by your body. Instead, it passes through your intestines, drawing water into your colon. The result? Softer, looser stools that are easier to pass. While Duphalac typically produces results within 1-2 days, the full effects may take 2-3 days. The good news is that it is gentle and has few negative effects when used for a short period of time. Continue reading to learn everything you need to know about taking Duphalac syrup and what you can do to get the most out of it.

What Is Duphalac Syrup?

Duphalac syrup is a stool softener used to treat constipation. It works by attracting water to the intestines, allowing stool to flow more readily.

Duphalac contains lactulose, a type of sugar that isn’t digested. Instead, it passes into the intestines where it draws in water. This makes the stool softer and easier to pass. Duphalac comes as a liquid you swallow. The usual dosage for constipation is 15-30 mL, up to 3 times a day. It may take 2-3 days of use to become effective.

Some key points to know:

  1. Follow the directions and don’t take more than the maximum dosage. Excessive consumption might result in diarrhea and dehydration.
  2. Duphalac may cause gas, bloating, and cramping at first. This should subside once your body adjusts, but let your doctor know if side effects are severe or don’t go away.
  3. Don’t use Duphalac for more than 1 week unless directed by your doctor. Prolonged use can lead to a reliance on the medicine to facilitate bowel movements.
  4. Duphalac is safe for short-term use, but talk to your doctor before using long-term or if you have any underlying conditions.
  5. Stay hydrated while taking Duphalac to avoid dehydration. Drink plenty of water and other clear fluids.

If your constipation does not improve with Duphalac or you have any concerns, consult your doctor. They may recommend diet changes, exercise, or alternative treatments to relieve your symptoms in a safe and effective way.
