Gastrointestinal
This category brings together treatments and supports for the Gastrointestinal system. It spans common reflux and nausea care to bowel motility therapies, plus options for symptom relief, short-course antimicrobials, and maintenance medicines so you can compare brands, forms, and strengths alongside class guidance. We provide US shipping from Canada on many items, and inventory may vary by supplier, formulation, or strength without notice. You can review ingredients, typical dose ranges, storage notes, and pill counts on each page to plan your next step responsibly.
Gastrointestinal Overview
Digestive health affects comfort, nutrition, and daily energy. This category covers acid suppression, antispasmodics for cramping, antiemetics for nausea, laxatives and prokinetics for constipation, and selective anti-infectives when prescribed. In clinical terms, gastroenterology addresses disorders of the upper and lower digestive tract. In plain language, that means caring for your stomach, food pipe, and bowels, along with the pancreas, liver, and bile ducts. We encourage a steady, stepwise approach that follows your clinician’s plan and recognizes when escalation or de-escalation is appropriate.
Some options are nonprescription, while others require a valid prescription and closer monitoring. Labels describe timing with meals, dose limits, and key cautions such as drug interactions. If you want background reading before choosing, explore our Gastrointestinal Articles for plain-language guides, class comparisons, and safety pointers you can bring to your next appointment. Thoughtful, informed browsing helps you choose treatments that fit your goals and daily routine.
What’s in This Category
You will find acid reducers, including H2 blockers and proton pump inhibitors, antispasmodics for cramps, antiemetics for nausea, and therapies for constipation or diarrhea. Some products support the mucosal lining, while others target inflammation or motility. Many focus on the gastrointestinal tract in specific ways, such as reducing acid exposure to protect the esophagus or moderating bowel spasms during flare days. Read the product details to understand where the medicine acts and how fast relief may begin.
To compare common choices, review an H2 Blocker for heartburn, an Anti-Nausea Tablet for vomiting, or an IBS Antispasmodic for cramping. Each class has distinct onset times and interaction profiles. For example, antispasmodics can cause dry mouth or drowsiness, while antiemetics may interact with other serotonergic drugs. Always review cautions, including pregnancy, breastfeeding, and kidney or liver considerations, before adding a new therapy to your routine.
How to Choose
Start with your primary concern, timing, and severity. For frequent heartburn, a daily proton pump inhibitor may help, while occasional symptoms might fit an H2 blocker taken before triggers. For constipation related to opioid treatment, a peripherally acting agent could suit you better than a stimulant laxative. For delayed gastric emptying, a motility-focused option may be discussed after other measures, including hydration, fiber, and meal-size changes.
Match the form to your needs and setting. Liquids and orodispersible tablets can help if swallowing is difficult. Coated tablets may protect the active ingredient from stomach acid. If reflux is persistent, review a proton pump inhibitor primer such as Dexilant Overview to understand onset, duration, and step-down strategies. If nausea relates to gastric stasis, see Domperidone Uses for context on mechanism and monitoring. Track your gastrointestinal symptoms with a brief diary, including triggers, timing, and response.
Popular Options
For frequent heartburn or erosive esophagitis, Prevacid (lansoprazole) provides acid suppression that can support healing under a clinician’s plan. It is often taken before breakfast and sometimes used as a step-down after an intensive course. Review drug interactions, especially with agents needing acidic absorption, and check how long continuous therapy is recommended for you.
For opioid-induced constipation, Movantik (naloxegol) works peripherally on gut receptors to improve bowel function without reversing pain control. It may be suitable when dietary fiber, hydration, and osmotic laxatives have not been enough. Short courses of targeted antibiotics may be part of gastrointestinal infection treatment in other scenarios, but these require medical guidance and clear diagnostic rationale to avoid resistance and adverse effects.
Related Conditions & Uses
Many products here are used alongside lifestyle steps for reflux, nausea, irritable bowel syndrome, or post-infection recovery. When infection is suspected, see our condition page on Gastrointestinal Infection for general features, red flags, and clinician-led care pathways. Treatment choices depend on illness severity, hydration status, and risk factors like older age or recent antibiotic exposure.
For inflammatory bowel disease discussions, our Pentasa Guide explains a mesalamine option used in specific cases, including dosing and safety basics. Cancer-related entities may have highly specialized regimens and supportive care needs distinct from general digestive care. Coordinate closely with your oncology or GI team, keep a medication list updated, and review interactions whenever a new medicine is added.

Frequently Asked Questions
Which items here are over-the-counter versus prescription?
Some acid reducers, anti-gas agents, and rehydration products are typically over-the-counter. Many antiemetics, antispasmodics, rectal steroids, and peripherally acting laxatives require a prescription. Product pages explain regulatory status and any eligibility steps. If a prescription is needed, your clinician must confirm the medicine, dose, and duration. Always review cautions, especially for pregnancy, liver or kidney disease, and drug interactions, before deciding.
How can I compare forms and strengths effectively?
Use filters to narrow by form, such as tablets, capsules, liquids, or orodispersible options. Then review product pages for milligram strength, pack size, and typical dosing schedules. Consider swallowing comfort, storage needs, and timing with meals. If your prescriber noted a specific class or dosing window, match that first. Keep a simple symptom and dosing diary to see what aligns with your routine and goals.
What if the item I want appears out of stock?
Stock can vary by supplier, strength, and season. If a product shows limited or unavailable, consider comparable formulations or strengths within the same class. Check similar items in the category and read the class notes for safe substitutions. Keep your prescriber informed about any change in formulation or dose. Revisit later, as supply patterns may change without notice.
How are temperature-sensitive or special-handling items managed?
Product pages note storage ranges and special handling, such as protection from moisture or light. Follow labeled guidance and consider delivery timing that avoids heat extremes. Some items require refrigeration before opening, while others should not be refrigerated. If you are unsure about transport conditions, plan for timely receipt and avoid prolonged exposure in vehicles or mailrooms. When needed, discuss backup options with your clinician.
Can I get guidance on side effects and interactions before I browse?
Yes. Class summaries outline common effects, such as headache, constipation, or drowsiness, and note relevant interactions. For example, acid reducers can change absorption of some drugs, and antispasmodics may cause dry mouth. Read labels closely and compare across similar products. Keep a current medication list and bring any concerns to your clinician for individualized advice before starting a new therapy.
