You’re doubled over. It’s that familiar, nagging cramp or maybe a sharp, "did-I-eat-a-brick" sensation right in the center of your gut. Naturally, you reach for the nearest bottle in the bathroom cabinet. Stop. Honestly, the most common mistake people make is treating every stomach pain like it’s the exact same problem. It isn't. Determining what to take for tummy ache depends entirely on whether you’re dealing with excess acid, trapped gas, a slow gallbladder, or just a literal "stomach bug" (gastroenteritis).
Most folks think Pepto-Bismol is a magic wand. Sometimes it is. Other times, it’s like trying to put out a grease fire with a glass of water—it just doesn't work that way.
Understanding the "Why" Before the "What"
If your stomach hurts because you overindulged in a spicy taco platter, your solution is miles away from what you’d need if you caught a Norovirus from your toddler. Doctors generally categorize abdominal pain by its behavior. Is it a burning sensation high up in the chest? That’s likely GERD or acid reflux. Is it a localized, sharp pain in the lower right? That’s a "go to the ER" situation because of the appendix.
For the garden-variety "my stomach just hurts" scenario, we look at symptoms like bloating, nausea, and cramping. According to the Mayo Clinic, many "tummy aches" aren't even in the stomach itself but in the small or large intestines. This distinction is huge. If you take an antacid for gas trapped in your colon, you're basically wasting your time.
The Heavy Hitters: Over-the-Counter Options
When people ask what to take for tummy ache, they usually want a quick OTC fix.
Calcium Carbonate (Tums, Rolaids)
These are the basics. They work by neutralizing the acid already sitting in your stomach. They are fast. We're talking minutes. But here's the kicker: they don't stop your body from making more acid. If you have a legitimate case of indigestion from a heavy meal, these are your best friend. If you have a virus? They’re useless.
Simethicone (Gas-X, Mylanta Gas)
This is a surfactant. Basically, it breaks up big gas bubbles into smaller ones so they can pass more easily. If you feel like a literal balloon is inflating under your ribs, simethicone is the gold standard. It doesn't get absorbed into your bloodstream, which makes it one of the safer options for most people.
Bismuth Subsalicylate (Pepto-Bismol, Kaopectate)
The pink stuff. It’s actually a derivative of aspirin (salicylate), which is why you shouldn't give it to kids due to Reye’s syndrome risks. It’s an anti-inflammatory and an antidiarrheal. It coats the stomach lining. If your tummy ache comes with a side of "the runs," this is usually what a GP will suggest.

H2 Blockers and PPIs (Famotidine, Omeprazole)
These are for the long haul. Famotidine (Pepcid) starts working in about an hour and lasts all day. Omeprazole (Prilosec) is even more intense—it actually shuts down the "pumps" that make acid. You don't take these for a one-off stomach ache from eating too much candy. These are for chronic "my stomach always hurts after I eat" issues.
The Natural Route: Does Ginger Actually Work?
You've heard it a thousand times: "Drink some ginger ale."
Well, most commercial ginger ale has zero real ginger in it. It’s just high-fructose corn syrup and "natural flavors." However, actual ginger root is a different story. A study published in the journal Nutrients confirmed that ginger accelerates gastric emptying. Basically, it helps move food out of the stomach and into the small intestine faster. If your ache is from "feeling too full," ginger is scientifically backed.
Peppermint oil is another one. It’s an antispasmodic. It relaxes the smooth muscles of the gut. This is specifically helpful for IBS-related pain. But a word of caution: if your stomach ache is actually heartburn, peppermint can make it worse by relaxing the sphincter that keeps acid down.
The BRAT Diet Myth
For decades, the advice for a sick stomach was Bananas, Rice, Applesauce, and Toast (BRAT).
Times have changed.
The American Academy of Pediatrics actually moved away from recommending BRAT as a primary treatment. Why? Because it’s too restrictive and lacks the protein and fats needed for the gut lining to actually repair itself after an illness. While these foods are "safe" because they are low-fiber and won't stimulate a bowel movement, they aren't a cure. They are just "holding pattern" foods.

When "What to Take" Becomes "Where to Go"
There are moments when reaching for a bottle of Maalox is actually dangerous. If you have a "tummy ache" that is accompanied by a fever, you aren't looking at indigestion. You're looking at an infection or inflammation.
- Rebound Tenderness: If it hurts more when you release pressure on your stomach than when you push down, call a doctor.
- The "Board-Like" Abdomen: If your stomach feels rock hard and you can't suck it in, that’s a sign of peritonitis.
- Localized Lower Right Pain: Could be the appendix.
- Upper Right Pain under the Ribs: Often signals gallbladder issues, especially after a fatty meal.
In these cases, taking an antacid or a laxative can actually cause a rupture or worsen the condition. If you're vomiting blood (or something that looks like coffee grounds) or if your stool is black and tarry, skip the pharmacy and go to the ER.
The Role of Probiotics
Sometimes the "ache" is actually a microbiome imbalance. If you've recently finished a round of antibiotics and your stomach has felt "off" ever since, you don't need an antacid. You need bacteria. Specifically, strains like Lactobacillus rhamnosus GG or Saccharomyces boulardii (which is actually a beneficial yeast).
Research from the World Journal of Gastroenterology suggests that probiotics can significantly reduce the duration of stomach-related distress, but they aren't an "instant fix." You won't take a capsule and feel better in twenty minutes. It’s more like a three-to-five-day process of re-balancing the internal ecosystem.
Real World Scenario: The "Holiday Gut"
We’ve all been there. It’s 11:00 PM on Thanksgiving or after a massive birthday dinner. Your stomach feels like it’s being stretched from the inside.
In this specific case, the best thing to take is actually... nothing. Or, specifically, water and a walk. Movement stimulates peristalsis—the wave-like contractions that move food along. If you must take something, a dose of simethicone to handle the air you swallowed while eating too fast is usually the smartest play.
Avoid laying flat. Gravity is your friend. If you lie down immediately after a big meal, you're inviting stomach acid to travel up your esophagus, turning a simple "full" feeling into a burning nightmare.

Why You Should Be Careful With NSAIDs
This is the big "don't." If your stomach hurts, do not take Ibuprofen (Advil/Motrin) or Aspirin. These are non-steroidal anti-inflammatory drugs. They work by inhibiting enzymes called COX-1 and COX-2. The problem? COX-1 is responsible for maintaining the protective mucus lining of your stomach.
Taking Advil for a stomach ache is like trying to fix a hole in your roof by throwing a rock at it. It might numb a headache, but it will actively irritate the stomach lining and can even cause small bleeding ulcers if you're already stressed or dehydrated. If you absolutely need a painkiller for a non-stomach-related issue while your tummy hurts, Acetaminophen (Tylenol) is the safer bet because it doesn't affect the stomach lining the same way.
Actionable Steps for Relief
Instead of panic-buying every bottle on the shelf, follow this logic flow to figure out exactly what to take for tummy ache:
- Identify the sensation. If it’s burning in the throat/chest, go for an antacid (Tums) or an H2 blocker (Pepcid).
- Check for bloating. If you feel "inflated" and are burping or passing gas, simethicone (Gas-X) is the answer.
- Assess the "bathroom situation." If you have diarrhea, bismuth subsalicylate (Pepto) is the move. If you haven't gone in three days, you might actually be experiencing "backup" pain, in which case a stool softener or magnesium supplement is better than an antacid.
- Hydrate correctly. Don't chug water. Sip room-temperature water or an oral rehydration solution (like Pedialyte). High-sugar sports drinks can actually make diarrhea worse because the sugar pulls more water into the gut.
- Heat therapy. A heating pad on a low setting can relax the muscles of the abdomen. This is especially effective for menstrual cramps that feel like "stomach aches" or for general stress-induced gut tension.
Ultimately, your gut is a second brain. It's incredibly sensitive to what you put in it, but also to your stress levels. If your stomach ache is chronic—happening more than twice a week—stop self-medicating. Chronic use of antacids can lead to "acid rebound," where your stomach overproduces acid to compensate for the medicine, creating a vicious cycle. Get a breath test for H. pylori or talk to a gastroenterologist about potential food sensitivities like celiac or lactose intolerance.
For the occasional, "oops I ate too much" or "I caught a bug" moment, stick to the basics. Neutralize the acid, break up the gas, stay hydrated, and give your digestive system the 24 hours of rest it's begging for.
Next Steps:
- Monitor your temperature; if a fever develops above 101°F, contact a healthcare provider.
- Switch to a "bland" diet of plain crackers and broth for the next 12 hours to let the gut rest.
- Check the active ingredients in your medicine cabinet to ensure you aren't doubling up on salicylates if taking Pepto-Bismol.
