Depends what kind of medicine you use. Medicine like Zantac (ranitidine) should work within the hour. Medicine like Gaviscon should work instantly. PPIs like Prilosec and Protonix should work within a week. However, after reading many different posts and forums PPIs depend on the person as they may react differently depending on the person.. It could take a month for them to work. Go to a doctor and follow their prescription dosage.
