The liquid medication has a pleasant peppermint flavor and comes in an easy-to-use 300ml bottle. The formula works by forming a protective layer on top of stomach contents, providing quick and long-lasting relief from acid reflux symptoms. Take as directed after meals and at bedtime. Always read the label and follow dosage instructions. If symptoms persist, consult your healthcare provider.
