Drug Class: H2-Receptor Antagonist | Form: Oral Tablet | Prescription Status: Prescription Only (Rx) — DRAP Registered
What is Famot 40mg Tablet?
Famot 40mg contains a higher dose of Famotidine — prescribed when stronger or more sustained acid suppression is needed than the 20mg strength provides. It works by blocking histamine H2 receptors on the stomach's acid-producing parietal cells, reducing both daytime and nocturnal acid secretion at the source. The 40mg dose is particularly effective for active ulcer healing, erosive oesophagitis, and conditions of extreme acid overproduction such as Zollinger-Ellison syndrome where standard doses are insufficient.
What is Famot 40mg Used For?
- Active duodenal ulcer — short-term healing of ulcers in the small intestine (معدے کا السر)
- Active gastric ulcer — short-term treatment of stomach ulcers, typically over 4–8 weeks
- GERD and erosive oesophagitis — acid reflux causing damage to the food pipe lining (سینے کی جلن)
- Zollinger-Ellison syndrome — rare condition causing extreme acid overproduction requiring higher doses
- Prevention of ulcer recurrence — maintenance therapy after ulcer healing
How Does Famot 40mg Work?
Famotidine competitively blocks H2 receptors on parietal cells, stopping histamine from triggering acid secretion. At 40mg, it provides stronger suppression of both basal acid production and the nocturnal acid surge — the overnight peak in acid secretion that is a primary driver of ulcer formation and poor healing. Taking the tablet at bedtime targets this nocturnal acid peak directly, maximising ulcer healing overnight.

Frequently Asked Questions (FAQs)
Q: What is the difference between Famot 20mg and 40mg? Famot 40mg is prescribed for active ulcers, erosive oesophagitis, and conditions needing stronger acid suppression — your doctor will prescribe 20mg for milder symptoms or long-term maintenance.
Q: Why is Famot 40mg taken at bedtime for ulcers? Nocturnal acid secretion is the most damaging for ulcer healing — taking Famotidine at bedtime directly targets this overnight acid surge for maximum healing effect.
Q: How long before my ulcer heals with Famot 40mg? Most duodenal ulcers heal within 4 weeks and gastric ulcers within 8 weeks — your doctor will confirm healing and advise on maintenance therapy to prevent recurrence.
Q: Can Famot 40mg hide serious stomach conditions? Yes — Famotidine can mask symptoms of stomach cancer. Always have persistent or unexplained stomach symptoms fully investigated before starting long-term treatment.
