When Tums (calcium carbonate) no longer controls your heartburn, other options include H2 blockers such as famotidine (Pepcid) for longer-lasting relief, proton pump inhibitors like omeprazole (Prilosec) or esomeprazole (Nexium) for frequent symptoms, and alginate antacids like Gaviscon that form a barrier against reflux. Timing, dosing, drug interactions, and trigger foods all affect whether these work, and there are several important factors to consider before you switch, detailed below. Antacid failure, heartburn more than twice a week, difficulty swallowing, vomiting, unexplained weight loss, or chest pain spreading to the arm or jaw can point to GERD, an ulcer, or a heart issue needing prompt care, so review the complete answer below.
Because persistent heartburn can look identical to conditions that are far more serious, guessing at the next medication can delay the answer you actually need. A free, instant, online symptom check can help you understand what your symptoms may mean and decide whether self-treatment, a pharmacist visit, or a doctor's appointment is the right next step.

Heartburn happens when stomach acid splashes up into your esophagus, causing that familiar burning sensation. Tums (calcium carbonate) often provides quick relief by neutralizing stomach acid. But if you find Tums isn’t doing the job, there are other steps and treatments you can try. Below is a complete guide—based on credible sources such as the American College of Gastroenterology and Mayo Clinic—covering over‐the‐counter (OTC) and prescription options, plus lifestyle tips to help manage heartburn.
Tums are fast-acting antacids. They work by neutralizing acid on contact, but they:
If your heartburn is frequent, severe or lasts more than two weeks, you may need a different approach.
Antacids similar to Tums include:
Tips for antacids in general:
H2 blockers reduce the amount of acid your stomach makes. They take longer to work (30–45 minutes) but provide relief for up to 12 hours.
How to use H2 blockers:
PPIs are the strongest OTC acid-suppressing drugs. They block the pump that makes stomach acid.
Key points:
Alginates (Gaviscon®) combine with antacids to form a protective “raft” that sits on top of stomach contents, reducing reflux. They’re especially helpful if you lie down soon after eating.
If OTC treatments aren’t enough, your doctor may prescribe:
Prescription therapy should be guided by symptoms, test results (like endoscopy or pH monitoring), and overall health.
Medication often works best when paired with lifestyle changes:
Eat Smaller Meals
Avoid Trigger Foods
Time Your Meals
Elevate Your Head
Lose Extra Weight
Quit Smoking
Wear Loose Clothing
Frequent or severe heartburn can sometimes signal a more serious condition (like GERD, peptic ulcer disease or even, rarely, heart problems). If Tums and other OTC remedies aren’t helping, consider:
If you have any of these alarming signs, speak to a doctor right away.

If Tums aren’t providing enough relief:
Heartburn can often be managed effectively with the right combination of treatments and habits. But never ignore severe or lasting symptoms—they deserve prompt medical attention.
