Buy Omeprazole Capsules (10mg & 20mg) Online In The UK

 

Omeprazole 10mg & 20mg capsules are frequently used proton pump inhibitors (PPIs) that are used to lower the production of acid in the stomach and treat symptoms associated with GORD. These capsules help block the acid-producing pumps in the stomach lining, helping relieve symptoms such as persistent heartburn, acid reflux, indigestion, sour taste in the mouth, chest burning, and reflux-related throat irritation.

 

Both 10mg and 20mg strengths are commonly used to treat: 

 

  • Acid reflux (GERD) 
  • Heartburn & indigestion 
  • Stomach ulcers and duodenal ulcers 
  • Oesophagitis (inflammation of the food pipe) 
  • Prevention of NSAID-related ulcers 
  • Long-term management of chronic acid-related disorders 
  • Reflux-related cough or laryngopharyngeal reflux (LPR) 

 

Omeprazole capsules are gastro-resistant, meaning they bypass the stomach and dissolve in the intestine for maximum absorption. This ensures consistent and reliable acid reduction for up to 24 hours with just one daily dose. 

 

How Omeprazole Works 

 

Omeprazole serves as a proton pump inhibitor and works on the proton pumps, which are found on the parietal cells in the stomach. It is these pumps that secrete gastric acid. With suppression of acid, Omeprazole offers an effective inhibition of gastric acid production that: 

  • Relieves burning chest pain and discomfort 
  • Allows ulcers to heal 
  • Reduces regurgitation and sour taste 
  • Prevents future flare-ups 
  • Protects the stomach during NSAID use 

 

That makes Omeprazole one of the most reliable and fastest-acting treatments for long-term acid-related conditions. 

 

Standard Dosage

Adults (including elderly):

  • Omeprazole 20mg:

    Take one capsule once daily, preferably in the morning before breakfast.
  • Omeprazole 10mg:

    Used for mild symptoms or maintenance therapy; take one capsule once daily.

For more severe symptoms, a doctor may advise 20mg twice daily for a short period.

How to Take the Capsules

  • Swallow the capsule whole with a glass of water.
  • Do not crush, chew, or break, as this damages the gastro-resistant coating.
  • Take 30–60 minutes before a meal for best results.
  • If you struggle with swallowing:

    Open the capsule and mix the granules in a spoonful of apple sauce or yogurt.

    Swallow immediately without chewing.


Length of Treatment

  • Acid reflux / heartburn: 2–4 weeks
  • Stomach ulcers: 4–8 weeks
  • NSAID protection: As long as NSAIDs are used
  • Chronic conditions: long-term under medical supervision

If symptoms do not improve within 14 days, consult a clinician.
