Antacids things needs to remember
Provide excellent symptom relief, usually in 5 minutes or less, and lasts 20-30 minutes
Food helps keep antacid in the stomach (up to 3 hours if administered within 1 hour of a meal

Histamine Type 2 Receptor Antagonists (H2RA) OTC options
Cimetidine, ranitidine, famotidine and nizatidine
Histamine Type 2 Receptor Antagonists (H2RA)
Block histamine from stimulating the parietal cell receptor thus decreases gastric acid secretion and gastric volume
H2RA may be used
Onset of symptoms

No more than 2 times per day and only for 2 weeks
H2RA side effects
