What is the L194 White Pill?
The L194 white pill is an over-the-counter (OTC) medication containing Famotidine 20 mg, a well-known H2 blocker used to treat acid-related issues such as:
-
Heartburn

What Does Famotidine Do?
Famotidine works by reducing the amount of acid your stomach produces. Unlike antacids that neutralize existing acid, Famotidine acts at the source: the acid-producing cells.
Comparison | Antacids | Famotidine |
---|---|---|
How it works | Neutralizes existing acid | Reduces acid production |
Speed | Fast (within 15 mins) | Slower (30–60 mins) |
Duration | Short (1–2 hrs) | Long (up to 12 hrs) |
This makes L194 ideal for prevention, not just relief.
