How does Peptac treat heartburn symptoms?

Peptac liquid relieves heartburn and indigestion symptoms through its three main ingredients: sodium bicarbonate, sodium alginate and calcium carbonate.

Together, these three ingredients work to neutralise excess acid in your stomach. By doing so, this medicine effectively reduces and relieves symptoms such as bloatedness, flatulence, nausea and uncomfortable, burning sensations in your chest.

The liquid is easy to swallow, measure and has an aromatic aniseed flavour.


What is the recommended dose of this treatment?

Peptac is suitable for adults and children over the age of six. Do not give to children younger than six years old. It is also suitable for treating heartburn and indigestion symptoms during pregnancy.

The recommended dose for adults and children over the age of 12 is two - four spoonfuls. You can use a teaspoon (5ml) to measure the dose.

For children aged 6 to 12, the recommended dose is one-two teaspoons.

Take the liquid by mouth, directly after meals and just before bedtime. Do not take more than 4 doses per day.
