Why is this medication prescribed?

Prevacid is a brand name for lansoprazole, a medication that belongs to a class of drugs known as proton pump inhibitors (PPIs). It is commonly prescribed for the treatment of conditions related to excess stomach acid. Here are some of the main reasons why Prevacid may be prescribed:

  • Gastroesophageal Reflux Disease (GERD): Prevacid is often prescribed to treat GERD, a condition where stomach acid flows back into the esophagus, causing symptoms such as heartburn and irritation.
  • Peptic Ulcers: Prevacid may be used to heal and prevent peptic ulcers, which are sores that develop on the lining of the stomach or the upper part of the small intestine.
  • Zollinger-Ellison Syndrome: This is a rare condition where the stomach produces too much acid. Prevacid may be prescribed to manage the excessive acid production in such cases.
  • Erosive Esophagitis: Inflammation and damage to the esophagus caused by stomach acid can be treated with Prevacid to allow healing.
  • Helicobacter pylori Infection: In combination with antibiotics, Prevacid may be prescribed to eradicate H. pylori bacteria, which is associated with the development of peptic ulcers.

How should this medicine be used?

Prevacid (lansoprazole) is typically used to reduce the production of stomach acid and is prescribed for various conditions related to excessive gastric acid. The following general guidelines provide an overview of how Prevacid is commonly used, but it’s crucial to follow your healthcare provider’s specific instructions:

  • Dosage and Timing: Prevacid is usually taken once a day, before a meal. The medication comes in different forms, including capsules, oral disintegrating tablets, and oral suspension. Follow your doctor’s instructions regarding the specific form and dosage prescribed for your condition.
  • Swallowing Precautions: Swallow the Prevacid capsules whole with a glass of water. Do not crush, chew, or open the capsules, as they are designed to release the medication slowly.
  • Consistency: Take Prevacid at the same time each day to maintain a consistent level of the medication in your body.
  • Combination Therapy: In some cases, Prevacid may be prescribed in combination with antibiotics to treat Helicobacter pylori infections. If your doctor prescribes a combination therapy, follow their instructions carefully.
  • Duration of Treatment: The duration of treatment with Prevacid varies based on the specific condition being treated. Follow your doctor’s recommendations, and do not stop taking the medication without consulting them, even if you start feeling better.
  • Monitoring: Your healthcare provider may monitor your response to the medication and may adjust the dosage or treatment plan as needed.
  • Interaction with Food: Prevacid can be taken with or without food. However, taking it before a meal may enhance its effectiveness.
  • Missed Dose: If you miss a dose, take it as soon as you remember. However, if it’s almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.
  • Adverse Reactions: Be aware of any potential side effects or adverse reactions. If you experience severe or persistent side effects, contact your healthcare provider.

Always follow the specific instructions provided by your healthcare provider and read the medication guide that comes with the prescription. If you have any questions or concerns about how to use Prevacid, don’t hesitate to discuss them with your healthcare professional.
