  2. Do I take Gaviscon® before a meal?

    The tablets need to be chewed for the foam barrier mechanism to effectively and promptly begin working. Sucking on the tablets won't allow the foam barrier to form all at once potentially reducing the product's strength. Also, the tablets are somewhat large and are not designed to be swallowed whole.Back to top
