What is Antacids and how to take It

The Food and Drug Administration licences antacids to treat mild episodes of indigestion and heartburn. Antacids, available without a prescription, neutralize stomach acid but should be taken as directed to avoid digestive issues and increased food sensitivities; allergic reactions are also possible. Unlike H2 receptor blockers and proton pump inhibitors, ANTACIDS DO NOT REDUCE ACID SECRETION. 

They alleviate symptoms of excessive stomach acid, such as acid reflux, heartburn, and indigestion. Antacids come in liquid, chewable, and dissolvable tablet forms, with popular brands including Alka-Seltzer, Maalox, Mylanta, Rolaids, and Tums. While generally safe, individuals with certain conditions like heart failure or kidney issues should consult their doctors before using antacids containing aluminum hydroxide and magnesium carbonate due to potential sodium and electrolyte concerns.

When ingesting chewable tablets, make sure to chew them well before swallowing. Next, sip a full glass of water (8 ounces, or 240 millilitres), then repeat. Use this medicine orally as needed both before and after meals. Follow your doctor’s instructions or all instructions on the product’s packaging. Shake the bottle of this medication thoroughly before using each dose if you are using the liquid version. Using a pharmaceutical spoon or cup, carefully measure the prescribed dose. 

Avoid using an ordinary spoon because the dose might not be accurate. Chilling the suspension may improve its flavour. Prevent freezing. Taking the liquid form alone is advised, without any additional beverages. You can dilute your dose with water if necessary. 

Important information about Antacids

Following are some points that you should know about Antacids:

  • Antacids can interact with other medications, reducing their effectiveness or causing harmful interactions.
  • Antacids counteract the effects of excessive stomach acid by neutralizing it, relieving symptoms like heartburn. They work quickly but for a short duration, usually up to 2 hours.
  • Common side effects include diarrhea or constipation due to changes in digestive processes. Long-term or excessive use of antacids can lead to imbalanced electrolytes, affecting heart rhythm or muscle function. Some antacids with aluminum can cause phosphorus depletion, impacting bone health.
  • Although rare, allergic reactions like skin rashes, itching, swelling, and breathing difficulties can occur. Seek medical attention if such symptoms arise.
  • It should be taken with discussion after a doctor by renal and cardiac patients.
