Rennie® Deflatine relieves the pain and discomfort of bloating, flatulence, and trapped wind. Each tablet is formulated with simeticone, a highly effective anti-foaming agent that causes the trapped air bubbles to combine and disperse, helping to eliminate the symptoms discreetly and without embarrassment. Rennie Deflatine also contains antacids which provide effective relief from heartburn, indigestion and acid reflux. You must contact a doctor if you do not feel better or if you feel worse after 7 days
