          Kidneys and liver
          • People with kidney disease on dialysis may need to take a lower dose or avoid use. Your doctor can do blood tests to see if it's safe to use.
          • If you have kidney or hyperparathyroid disease Tums (Calcium Carbonate) can build up in your blood. This may can cause toxic levels of calcium in your body. This is more likely if you have severe kidney disease (defined as a kidney function blood test called GFR of less than 30ml/min). If you have severe kidney disease or are on kidney dialysis don't use Tums (Calcium Carbonate); a different antacid would be better for you.
          • Tums (Calcium Carbonate) contains calcium. Calcium can be an ingredient in some kidney stones. If you have had kidney stones in the past (especially the calcium-containing kind) be careful using Tums (Calcium Carbonate). Use the lowest dose for the shortest time possible or just play it safe and use a different antacid instead.

          Upsides and benefits
          • Works really fast.
          • Available over the counter without a prescription.
          • Cheap.
          • Most people can take Pantoprazole without any noticeable day-to-day side effects.
          • Pantoprazole lasts longer than other types of antacids (like Zantac, Pepcid, or Tums), and you only need to take it once or twice a day.
          • You can take it in combination with a quick-acting antacid (like Maalox or Tums) if you need relief right away.
          • In studies it was better than a placebo (sugar pill) and as good as other proton pump inhibitors at treating heartburn.
          • Available as both a generic and over-the-counter option, so it's pretty affordable.
          Downsides and risks
          • Doesn't last very long.
          • Other antacids like Zantac (H2 blockers) and omeprazole (proton pump inhibitors) can work better and last longer.
          • Some chalky aftertaste.
          • Doesn't start working as fast as some other antacids like Tums, Rolaids, or Maalox.
          • Like with other proton pump inhibitors, long-term use can cause weak or broken bones.
          • Can cause low levels of magnesium in the blood. You might need to take a magnesium supplement if you use Pantoprazole long-term.
          • Can be expensive. Other alternatives are usually cheaper than Pantoprazole.
          • Less risk of drug interactions with Pantoprazole than with other proton pump inhibitors.
          Tips from our pharmacists for people taking the medication
          • Take at the first sign of discomfort.
          • You might need to take more than once a day but pay attention to the instructions on your bottle to avoid overdosing.
          • You need to separate Tums from some medications to avoid interactions.
          • If heartburn doesn't improve or lasts more than 2 weeks, talk to your doctor.
          • People with kidney disease on dialysis may need to take a lower dose or avoid use. Your doctor can do blood tests to see if it's safe to use.
          • Don't take if you have high blood calcium levels.
          • Take with or without food.
          • Swallow tablets whole; don't split, crush, or chew.
          • Take the oral suspension 30 minutes before a meal mixed only with applesauce or apple juice. Follow instructions carefully.
          • When using Pantoprazole long-term, take a calcium citrate with vitamin D supplement daily to prevent bone loss. Be sure it's calcium citrate because it works the best when using a proton pump inhibitor.
          • Get a blood test for your magnesium level once a year; you may need a magnesium supplement while using Pantoprazole.
          • Avoid drug interactions by telling your doctor all of the other medications or herbal supplements you take before starting Pantoprazole.
