A Tale of Two Products: The Name Game
When comparing medications and supplements, precise naming is crucial. The question of whether Gastrex is the same as Gastro-Stop is a perfect example of this, as the answer is both yes and no, depending entirely on which 'Gastrex' you are referring to. In Australia, Gastrex is a brand name for a pharmaceutical drug used to treat diarrhea. In the United States, Gastrex is the name of a whole-food nutritional supplement from the company Standard Process. These two products have nothing in common besides the name and a general connection to the digestive system.
The Anti-Diarrheal Drug: Gastro-Stop and Gastrex (Loperamide)
Gastro-Stop is a widely known over-the-counter medication for the symptomatic relief of diarrhea. Its sole active ingredient is Loperamide Hydrochloride. Loperamide is an opioid-receptor agonist that works by binding to opioid receptors in the gut wall. This action slows down the propulsive movements of the intestines, allowing more time for water and electrolytes to be absorbed from the stool, thus making it firmer and reducing the frequency of bowel movements.
In Australia, a product also named Gastrex is marketed as a generic alternative to Imodium and Gastro-Stop. It contains the exact same active ingredient: loperamide hydrochloride. Therefore, in the context of Australian pharmacy, Gastrex and Gastro-Stop are functionally identical and used for the same purpose: controlling acute, non-specific diarrhea.
Important Safety Information for Loperamide: Loperamide should not be used if the diarrhea is accompanied by a high fever or if there is blood or mucus in the stool, as this could indicate a bacterial infection that the body needs to expel. Using more loperamide than recommended can lead to serious side effects, including severe constipation, abdominal pain, and potentially life-threatening cardiac events. Always follow package directions or a doctor's advice.
The Nutritional Supplement: Gastrex by Standard Process
In contrast, the Gastrex manufactured by Standard Process in the US is a dietary supplement, not a pharmaceutical drug. Its purpose is to provide broad nutritional support for the digestive system.
Instead of a single active drug, it contains a proprietary blend of whole foods, vitamins, and animal-derived glandular extracts. Key ingredients include:
- Okra
- Spanish moss (Tillandsia usneoides)
- Anise seed
- Bovine liver and porcine stomach extracts
- Alginic acid
- Vitamins C, B6, and Niacin
This formulation is intended to support the body's natural digestive processes, help maintain a healthy GI lining, and support cleansing of the upper GI tract. It is used by consumers for general digestive discomfort, bloating, and as nutritional support for chronic conditions like gastritis, not as an immediate remedy for acute diarrhea. Unlike loperamide, it does not have an anti-motility effect to stop diarrhea quickly.

Conclusion
So, is Gastrex the same as Gastro-Stop? If you are in Australia and referring to the loperamide-based anti-diarrheal, then yes, they are equivalent generic and brand-name products. However, if you are referring to the Standard Process Gastrex available in the US, then no, they are fundamentally different. One is a targeted pharmaceutical designed to stop the symptom of diarrhea quickly, while the other is a nutritional supplement designed for long-term digestive health support. Always check the active ingredients and intended use on the label to ensure you are using the correct product for your needs.
