Antacids 1-3 HR PROTECTION

Antacids work to neutralize the acid in your stomach. But unlike Nexium 24HR, antacids can’t block the production of acids before it starts and only lasts 1-3 hours.

Histamine Blockers (H2s) 12 HR PROTECTION

Histamine blockers (H2s), like Zantac, block a signal that prompts the body to produce acid. While they can go into effect within 30 minutes, H2s only last up to 12 hours and can lose their efficacy if used for more than a few days.

Nexium 24HR Protection

Proton pump inhibitors, or PPIs, stop the production of acid before it starts and have a longer lasting effect than antacids and histamine blockers (H2s). This is why taking just one Nexium 24HR pill a day can protect and provide relief for 24 hours

PPIs vs. Antacids

What’s the difference between antacids and PPIs? Antacids neutralize stomach acid, and while they work quickly, its effects only last for 1-3 hours after use. PPIs, like the ones in Nexium24HR, go straight to the source and block acid production before it starts for 24 hours.*

PPIs vs. H2 Blockers

What’s the difference between PPIs and Histamine blockers (H2)? H2s, like Zantac, work to block one of the signals that prompt your body to make acid. Effects can take place within 30 minutes, but for a maximum of 12 hours. PPIs, like Nexium 24HR, work differently by blocking the source of acid production for 24 hours.*
