Risks from prolonged use of antacids
Anti-acid drugs are a popular, over-the-counter (OTC) drug, often used to reduce heartburn, indigestion or acid reflux. However, drug abuse can lead to many unwanted side effects.
Constipation: Anti-acid drugs containing calcium (such as Tums, calcium carbonate) or aluminum can cause constipation, bloating and flatulence. Users need to increase fiber, drink plenty of water or switch to other appropriate medications.
Diarrhea: In contrast, medications containing magnesium (eg, magnesium milk, magnesium hydroxide) are prone to diarrhea, nausea and abdominal pain, especially when taken in high doses.
Electrolyte imbalance: When consumed too much, the body can have trouble concentrating minerals such as calcium, magnesium, and aluminum. This affects heart, muscle and nerve activity. Symptoms include dizziness, cramps, irregular heartbeat, and even confusion.
kidney stones: Some antacids containing calcium can increase the risk of kidney stones, especially if the patient also takes calcium supplements.
Osteoporosis: Anti-acid drugs containing aluminum when used for a long time will hinder calcium absorption, causing weak bones and increasing the risk of fractures.
pharmacologist Mary Choy, PharmD, an expert in New York, USA, warned: "Many people consider antacids harmless because they sell them without a prescription. But if used for a long time, they can damage the kidneys and bones."
Use safe drugs: Principles to remember
Experts recommend that antacids should only be taken for a short time to temporarily reduce symptoms. If the patient has to use it every day, they need to see a doctor to check the cause and have appropriate treatment.
Dr. Karen Berger, author of the study published on October 1, 2025, emphasized: "Anti-acid drugs are not a long-term treatment replacement. Patients should change their lifestyle: eat scientifically, quit smoking, maintain weight to prevent heartburn".
Some important notes:
Do not arbitrarily take high or prolonged doses.
Consult your doctor or pharmacist before choosing a medication.
Pay attention to the ingredients in the medicine to avoid side effects.
Combine a healthy diet, limit foods that cause reflux.
"Anti-acid drugs are just an immediate solution," said digestive experts at New Jersey Medical University Hospital. If overused, patients can easily ignore more dangerous signs of illness, such as gastric ulcers or chronic reflux."
Proper use not only helps control symptoms but also limits long-term health risks.
