Losec works by calming your stomach and reducing irritation and discomfort caused by excess stomach acid. This helps relieve symptoms such as heartburn and indigestion, making it an effective treatment for those suffering from acid-related stomach issues.
Generally, Losec begins to reduce symptoms like heartburn and acid reflux one to two days after starting them. Taking your Losec capsule around the same time each day helps maintain a steady level of medication in your body, which aids in effectively managing your symptoms.

When you are prescribed Losec, your pharmacist or doctor will provide you with full instructions specific to your condition.
If you’re unsure how to take Losec, speak to one of our medical professionals or read the patient information leaflet.
