Description

Omeprazole is a proton pump inhibitor (PPI) that suppresses gastric acid production by irreversibly inhibiting the H⁺/K⁺ ATPase enzyme in stomach lining cells. It is commonly used to treat gastroesophageal reflux disease (GERD), peptic ulcers, Zollinger–Ellison syndrome, and to prevent acid-related complications. 

2. Prescription

This medication is prescription-only (POM/Rx‑only) in most jurisdictions. 

3. Therapeutic Category

Proton pump inhibitor (PPI) used in the pharmacotherapeutic group “drugs for acid-related disorders” (ATC code A02BC01). 

4. Active Ingredients / Composition

• Active Ingredient: Omeprazole 20 mg per capsule/tablet (enteric-coated). 
• Excipients: Often include sucrose, lactose, hypromellose acetate succinate, sodium starch glycolate, talc, iron oxides (capsule coating), among others.

5. Vitamins

None.

6. Minerals

None.

7. Variant

• Available primarily in 20 mg enteric‑coated capsules or gastro‑resistant tablets.
• Other variants include 10 mg and 40 mg strengths, as well as combinations (e.g. omeprazole with sodium bicarbonate).
  

8. Consume Type

Oral administration. Capsules or tablets are swallowed whole. If necessary, capsules can be opened and pellets mixed with applesauce or juice—but must not be chewed. 

9. Directions / Usage

• Adults (standard dose): 20 mg once daily, typically in the morning before meals. Duration depends on indication (e.g., 2–8 weeks for ulcers, longer for reflux) 
• Other uses: H. pylori eradication (with antibiotics), NSAID-associated ulcers, and reflux.

10. Common Side Effects

Common (1–10%): headache; gastrointestinal effects such as abdominal pain, diarrhea, constipation, nausea, flatulence.
Less common: dizziness, skin reactions, blood cell changes. Rare but serious: severe cutaneous reactions (e.g. Stevens–Johnson syndrome), hypomagnesemia, bone fractures, interstitial nephritis. 

11. Package Type

Typically blister packs—e.g., Alu‑Alu or Alu/PVC strips, in pack sizes ranging from 7 to 30 capsules/tablets. 

12. Storage Advice

Store in the original package, protected from moisture and not above 25 °C, in a cool, dry place away from sunlight and out of reach of children. 

13. Safety Advice

• Contraindications: Allergy to omeprazole or related PPIs; concurrent use with nelfinavir. 
• Precautions: Exclude gastric malignancy when ulcer suspected; long-term use (>1 year) increases fracture risk (especially hip, wrist, spine); monitor magnesium levels and bone health; rare skin reactions require immediate discontinuation.

• Drug Interactions: May reduce effectiveness of clopidogrel and affect absorption of certain medications.
• Special Populations: Pregnancy—use with caution; breastfeeding—omperazole is excreted in milk but unlikely to cause adverse effects. Use in children ≥1 year with appropriate supervision. 
• Chronic Use Risks: C. difficile infection, gastric cancer masking, nutrient malabsorption concerns (e.g., vitamin B₁₂, iron).
  

14. Product Substitute

Other PPIs (esomeprazole, pantoprazole, lansoprazole) or generic omeprazole variants.
