Frequently Asked Questions
What is the difference between Ranitidine and Famotidine?
+
Ranitidine and Famotidine are both H2 blockers that reduce stomach acid, but Famotidine is generally considered more potent and longer-lasting. Ranitidine was more commonly used in the past but has been withdrawn in many countries due to safety concerns.
Why was Ranitidine taken off the market?
+
Ranitidine was removed from many markets because it was found to contain NDMA, a potentially cancer-causing substance, especially when stored improperly or for long periods.
Is Famotidine safer than Ranitidine?
+
Yes, Famotidine is considered safer. Unlike Ranitidine, it has not been linked to NDMA contamination and is still approved and widely used to treat acid reflux and ulcers.
Can I switch from Ranitidine to Famotidine?
+
Yes, many people who previously took Ranitidine have switched to Famotidine. However, you should talk to a doctor to confirm the right dose and ensure it\'s suitable for your condition.
Which works faster: Ranitidine or Famotidine?
+
Both drugs work relatively quickly, but Famotidine tends to last longer. Its effects can last up to 12 hours, making it suitable for twice-daily dosing to control acid production.
