Prilosec (Omeprazole) gives you long-lasting heartburn relief. Choose the cheapest proton pump inhibitor because they all work equally well for heartburn.

Upsides
  • Zantac 75 (ranitidine) works well to relieve heartburn symtoms and is quite tolerable.
  • You can take it in combination with a quick-acting antacid (like Maalox or Tums) if you need relief right away.
  • If you have trouble swallowing pills you may find the liquid product a good option.
  • Inexpensive with over-the-counter and generic options.
  • Coupons are available for the brand product - speak to your doctor or pharmacist.
  • Most people can take Omeprazole without any noticeable day-to-day side effects.
  • Omeprazole 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
  • Zantac 75 (ranitidine) doesn't work as quickly as some other acid reducers. Speak to your doctor or pharmacist if you need quicker relief.
  • Zantac 75 (ranitidine) does not last as long as some other acid reducers. Speak to your doctor or pharmacist if you need longer relief.
  • May not be as effective in healing the esophagus when it is inflammed or torn, known as erosive esophagitis. Your doctor will assess which medication is best for you.
  • Can lower your vitamin B12 levels if you use Zantac 75 (ranitidine) for a long time. Your doctor can order lab tests to monitor your vitamin B12 levels.
  • 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 Omeprazole long-term.
  • Although the generic is affordable, other medications might still be cheaper than Omeprazole.
  • Can interact with other drugs so be sure your doctor knows all the medicine you're taking before starting Omeprazole.
