What Are Tums Chewable Tablets?
Tums chewable is an over-the-counter antacid made primarily from calcium carbonate. It works by neutralizing stomach acid, which can relieve heartburn, acid indigestion, and upset stomach. The chewable form means the tablet dissolves in the mouth rather than needing to be swallowed whole, allowing faster absorption and quicker symptom relief. Tums has been a household name for decades and remains one of the most accessible options for occasional acid discomfort.

How Tums Chewable Works in the Body
Calcium carbonate is a base, and when it contacts stomach acid (hydrochloric acid), it creates a chemical reaction that reduces acidity. This neutralization process happens relatively quickly once the chewed tablet reaches the stomach lining. The relief is usually felt within minutes, which is why many people reach for Tums chewable after eating a meal known to trigger symptoms. The calcium released during this process also serves as a dietary supplement, though the amount per tablet is modest compared to dedicated calcium supplements.
Proper Dosage and Usage Guidelines
For adults and children 12 years and older, the typical dose is 2 to 4 chewable tablets after meals and at bedtime, or as directed by a doctor. The tablets should be chewed thoroughly before swallowing. Do not crush or swallow them whole. Maximum daily intake varies by product strength, but exceeding the recommended dose can lead to serious side effects, including calcium overdose. Always check the specific product label, as Tums comes in several formulations including Tums Ultra, Tums Smoothies, and Tums Sugar Free.
Possible Side Effects and Risks
Most people tolerate Tums chewable well when used as directed, but side effects can occur. Common ones include constipation, gas, and bloating. Calcium carbonate can also cause belching or a chalky taste in the mouth. More serious risks arise with overuse or prolonged use, which may lead to hypercalcemia, kidney stones, or milk-alkali syndrome. Individuals with kidney disease, those on a low-calcium diet, or people taking certain medications should consult a healthcare provider before regular use.
When to Seek Medical Attention
Stop taking Tums chewable and contact a doctor if you experience severe stomach pain, nausea, vomiting, loss of appetite, confusion, or irregular heartbeat. These can be signs of calcium toxicity. Also seek help if heartburn symptoms persist for more than two weeks despite treatment, as chronic acid reflux may require a different approach.
Drug Interactions and Precautions
Calcium carbonate can interfere with the absorption of many prescription medications. Important interactions include certain antibiotics like tetracycline and ciprofloxacin, bisphosphonates used for osteoporosis, levothyroxine for thyroid conditions, and some iron supplements. To minimize interactions, take Tums chewable at least two hours apart from other medications. People on a sodium-restricted diet should note that some Tums formulations contain sodium. Pregnant individuals should also discuss antacid use with their healthcare provider.

Storage and Safety Tips
Store Tums chewable at room temperature away from moisture and heat. Keep the bottle tightly closed when not in use. As with all over-the-counter medications, keep Tums out of reach of children. Even though calcium carbonate is a mineral found in the body, a child accidentally consuming multiple tablets can lead to overdose symptoms including nausea, vomiting, and confusion. If an overdose is suspected, contact poison control or seek emergency medical care immediately.
