Omeprazole is not for immediate relief of heartburn. Omeprazole should be taken exactly as directed on the label, or as it was prescribed by your doctor. Omeprazole is usually taken before meals.
Omeprazole is available in delayed-release capsule, enteric coated tablet and powder form.
Do not crush, chew, or break an enteric-coated tablet. Swallow the tablet whole. The enteric-coated tablet has a special coating to protect your stomach. Crushing the tablet could damage this coating.
Dissolve the Omeprazole powder in a small amount of water. Add 1 teaspoon of water for the 2.5-mg packet, or 1 tablespoon of water for the 10-mg packet. Let the mixture stand for 2 or 3 minutes, then stir and drink right away.
Usual dose:
Gastroesophageal Reflux Disease: The initial dose is 20 mg once a day before a meal for 4 to 8 weeks. This may be increased to 40 mg per day if needed. Gastric Ulcer: 40 mg, once a day before a meal for 4 to 8 weeks.
Erosive Esophagitis: 20 mg once a day before a meal. For this indication, the dosage may be increased to 40 mg daily based on desired clinical response and patient tolerance.
Dyspepsia: to prevent frequent heartburn: 20 mg orally once daily, before a meal, for 14 days.
Omeprazole is used to treat symptoms of gastroesophageal reflux disease (GERD) and other conditions caused by excess stomach acid. It is also used to promote healing of erosive esophagitis.
Omeprazole may also be given with antibiotics in treating gastric ulcers caused by helicobater pylori.
