Frequently Asked Questions
Is Bismuth Subgallate safe for open wounds?
Yes, it's USP-monographed for topical hemostasis and wound protection.
Why does stool turn black after ingestion?
Normal reaction - bismuth forms black sulfide in GI tract (harmless).
Can it replace bismuth subsalicylate (Pepto-Bismol ®)?
Similar GI benefits but without salicylates (safer for aspirin-sensitive patients).
Shelf life and storage?
24 months unopened; store below 25°C away from light/moisture.
Is it vegan-friendly?
Gallic acid is plant-derived (tannins), but confirm sourcing for strict vegan needs.
