Treatments for acid reflux, ulcers, IBS, inflammatory bowel disease, nausea and constipation.

About Gastrointestinal Drugs medications

This category includes proton pump inhibitors such as omeprazole and pantoprazole, H2 blockers, antacids and alginates, antispasmodics for IBS, mesalamine and biologics for ulcerative colitis and Crohn's disease, anti-nausea medications, laxatives and pancreatic enzyme replacements.

Proton pump inhibitors work best taken 30 to 60 minutes before a meal, and are intended for defined courses rather than indefinite use without review. If reflux symptoms persist beyond a few weeks, see your prescriber.

Biologics for inflammatory bowel disease are cold-chain products and ship in insulated packaging.

Gastrointestinal Drugs — frequently asked questions

Can I buy omeprazole without a prescription?
Lower-strength omeprazole is available over the counter in some pack sizes; higher strengths and longer courses need a prescription. Each product page states which applies.
Do you stock treatments for H. pylori?
Yes. The antibiotic combinations used in eradication therapy are stocked and require a prescription.
Do I need a prescription to order?
Yes. Prescription medications require a valid prescription from your licensed prescriber. After you place your order you can upload, email, fax or mail it to us, and our pharmacy team verifies it before anything ships. Over-the-counter items and supplies do not need a prescription.
How long does delivery take?
Standard delivery to the United States usually takes 2 to 4 weeks from the day your prescription is approved. Expedited shipping is available at checkout, and temperature-sensitive medications ship in cold-chain packaging.
