Duphalac Reviews

For Constipation, Acute "The WORST medication I have ever taken. Not only does it NOT work, it makes everything 10x worse. Painful gas and flatulence at an unpreced level. Took it to deal with constipation post surgery and it made the surgery pain so much worse. Useless!"


For Constipation, Acute "I used this Duphalac syrup but I can say that its the worst medicine have seen ever in my life and has not even a single percent of laxative effect, in fact it had opposite effect to this it will even increase hardness of stool. If I would had an option to rate this medicine I would have rated it in negative. Such a waste company and product. I would request to don’t buy this medicine any chance. Rating: -10 the worst"


For Constipation, Chronic "I was struggling to pass bowel motions so decided to seek advice from a pharmacy. They asked what medication I was on. I informed them that I took Gliclacide for diabetes & Allopurinol for gout. They recommended Duphalac. I have following observations and advice. The leaflet recommended a dose of 15 - 45ml. I chose 15ml. within two hours I had a HYPO and bowel motions that lasted over an hour on & off. There was no warning of that possibility. Also I noted that the plastic bottle container cap was not childproof!! I do not recommend this product....AVOID."
