Prevacid vs Nexium
Introduction
For patients dealing with gastrointestinal issues like gastroesophageal reflux disease (GERD) or stomach ulcers, certain drugs can help by decreasing the amount of acid produced in the stomach. Prevacid and Nexium are two such medications that are often prescribed to manage these conditions. Both fall under a class of drugs known as proton pump inhibitors (PPIs), which work by blocking an enzyme in the stomach lining responsible for producing acid. Prevacid, also known as lansoprazole, reduces gastric acid secretion by binding irreversibly to available proton pumps within parietal cells. On the other hand, Nexium or esomeprazole inhibits final steps of gastric acid production, thus reducing basal and stimulated gastric acidity. Despite their different chemical structures and activity rates at various pH levels, both effectively treat symptoms related to excess stomach acid.
What is Prevacid?
Lansoprazole (the generic name for Prevacid) is a proton pump inhibitor that was an innovative progression from earlier classes of antacids. It was first approved by the FDA in 1995. Prevacid works by decreasing the amount of acid produced in the stomach, therefore providing relief from symptoms such as heartburn, difficulty swallowing, and persistent cough caused by acid reflux disease. It's prescribed to treat various conditions involving excessive stomach acid like Zollinger-Ellison syndrome.
On similar lines, Esomeprazole (the generic name for Nexium) also belongs to the class of proton pump inhibitors but it has a more targeted influence on gastric acid secretion with minor effects on other secretions which results in fewer side effects than Lansoprazole. Both drugs are used effectively to combat gastroesophageal reflux disease (GERD), peptic ulcer disease, and Zollinger–Ellison syndrome among others.
What conditions is Prevacid approved to treat?
Prevacid and Nexium are both approved for the treatment of various conditions related to excessive stomach acid:
- Gastroesophageal reflux disease (GERD), a chronic condition in which stomach acid flows back into the esophagus
- Healing and maintenance of erosive esophagitis, an inflammation that may damage tissues of the esophagus
- Treatment and prevention of gastric ulcers caused by NSAIDs, nonsteroidal anti-inflammatory drugs.
- Zollinger-Ellison syndrome, a rare condition where the stomach produces too much acid.
How does Prevacid help with these illnesses?
Prevacid helps to manage gastroesophageal reflux disease (GERD) by decreasing the amount of acid produced in the stomach. It achieves this by blocking an enzyme in the wall of the stomach that produces acid, thereby maintaining lower levels for longer periods. Stomach acid plays a crucial role in breaking down food and absorbing nutrients but can cause discomfort or damage when it reaches parts of the body where it doesn't belong such as esophagus and throat. People with GERD often have excessive amounts of gastric acid. Therefore, by reducing these acids, Prevacid can limit negative effects like heartburn and indigestion caused by GERD and help patients manage their condition more comfortably.
What is Nexium?
Nexium, also known as esomeprazole, is a proton pump inhibitor (PPI) that reduces the production of stomach acid by blocking the enzyme in the wall of the stomach responsible for its production. This action can decrease symptoms such as heartburn and difficulty swallowing caused by gastroesophageal reflux disease (GERD), along with preventing ulcers and even helping heal damage to your esophagus caused by stomach acid. Nexium was first approved by the FDA in 2001.
Being a PPI, Nexium doesn't inhibit serotonin reuptake but has its own unique side-effect profile. It does not cause sedation or sexual dysfunction like some SSRIs do. However, it may still lead to common adverse effects such as headache, diarrhea, nausea and flatulence among others although serious side effects are quite rare.
The reduced gastric acid secretion effects brought about by Nexium can be beneficial especially for those dealing with persistent GERD symptoms who have had little success with H2 antagonists or other standard treatments.
What conditions is Nexium approved to treat?
Nexium, known scientifically as esomeprazole, has been approved by the FDA for the treatment of conditions such as:
- Gastroesophageal Reflux Disease (GERD)
- Zollinger-Ellison syndrome
- Erosive esophagitis which is inflammation and damage to the tube connecting your mouth and stomach
- It can also be used alongside antibiotics in treating Helicobacter Pylori infection.
How does Nexium help with these illnesses?
Proton pumps are enzymes found in the stomach lining that help produce stomach acid. They play a critical role in the digestive process, but too much stomach acid can lead to discomfort and conditions such as gastroesophageal reflux disease (GERD). Nexium works by selectively inhibiting these proton pumps, reducing the amount of acid produced in the stomach. This helps alleviate symptoms associated with excessive acidity like heartburn or indigestion. Its action on proton pumps is slightly different than that of Prevacid, making it potentially more effective for certain patients based on their individual physiology and health needs. Just like Wellbutrin doesn't significantly affect serotonin levels and might be preferred when a patient doesn't respond well to typical SSRIs like Prozac, Nexium may be chosen over Prevacid if patients don’t react optimally to this form of treatment.
How effective are both Prevacid and Nexium?
Both lansoprazole (Prevacid) and esomeprazole (Nexium) are well-established proton pump inhibitors, used primarily to treat conditions caused by excess stomach acid such as gastroesophageal reflux disease (GERD). They were approved by the FDA just a few years apart, with Prevacid gaining approval in 1995 and Nexium in 2001. Since they act on similar mechanisms but have slightly different molecular structures, they may be prescribed under different circumstances. A report published in the American Journal of Gastroenterology compared these two drugs head-to-head for healing erosive esophagitis; the study concluded that both drugs had comparable efficacy in managing symptoms as well as promising safety profiles.
A review of meta-analysis reports on lansoprazole demonstrated that it is effective at reducing gastric acidity starting from first days of treatment. Its side effect profile is considered favorable amongst other proton pump inhibitors, and it has shown to be well-tolerated even among elderly populations or individuals with liver disease. The optimal dose for most patients appears to be 30 mg/day; beyond alleviating symptoms related to excess gastric acid production, it also seems effective at reducing associated complications such as peptic ulcers.
While a detailed comparison study was conducted between esomeprazole and omeprazole - its parent drug -, there hasn't been extensive direct comparisons against lansoprazole alone. Nonetheless, esomeprazole has proven efficiency over placebo and comparable efficacy with other proton pump inhibitors when treating GERD or erosive esophagitis according to multiple studies reviewed in Therapeutics Letter issued by Therapeutics Initiative group based out University of British Columbia's faculty medicine . Furthermore due its unique pharmacokinetics considerations might given prescribing this medication certain patient population who did not respond optimally others PPIs require more potent gastric acid suppression.
At what dose is Prevacid typically prescribed?
Oral dosages of Prevacid range from 15–30 mg/day, with studies indicating that 15 mg/day is enough for most people to treat gastroesophageal reflux disease (GERD). Children and adolescents may be started on a lower dose of about 15 mg/day. If there is no response after a few weeks, the dosage can be increased under the guidance of a healthcare professional. It's critical not to exceed the maximum dosage which in any case should not go beyond 30 mg/day. On the other hand, Nexium dosages generally range from 20-40mg per day for adults depending upon their condition and response to treatment. For children, it varies based on weight and age so medical advice must always be sought.

At what dose is Nexium typically prescribed?
Nexium treatment typically starts with a dosage of 20-40 mg/day. The dose can be increased up to 80 mg/day, depending on the severity of the condition and individual patient response. This is usually administered in two doses, split evenly throughout the day. For patients not responding to initial treatment after several weeks, or for those with severe gastroesophageal reflux disease (GERD), your healthcare provider may consider doubling the initial dose. As always, it's essential that any changes in dosing are done under medical supervision.
What are the most common side effects for Prevacid?
When comparing Prevacid to Nexium, some of the common side effects one might experience include:

As with any medication, it's important to weigh these possible side effects against the benefits when choosing your treatment.
Are there any potential serious side effects for Nexium?
Nexium, like most medications, has the potential to cause side effects. Some serious ones include:
- Symptoms of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue or throat
- Severe stomach pain and nausea
- A seizure (convulsions)
- Unusual changes in mood or behavior such as confusion, aggression or depression
- Blurred vision and dizziness
- Rapid heartbeat or irregular heart rhythms
- Signs of kidney problems: urinating less than usual, blood in your urine, swelling in your feet or ankles.
If you experience any of these signs after taking Nexium, seek immediate medical attention.
Contraindications for Prevacid and Nexium?
Both Prevacid and Nexium, along with most other proton pump inhibitors (PPIs), may worsen symptoms of acid reflux in some people if not taken correctly. If you notice your symptoms worsening or an increase in chest pain, severe stomach pain, or bloody/tarry stools, please seek immediate medical attention.
Neither Prevacid nor Nexium should be taken if you are using any medication that contains rilpivirine. Always tell your physician which medications you are taking; these drugs will require a period of about 2 to 3 hours before or after taking them with PPIs like Prevacid and Nexium to prevent dangerous interactions. Furthermore, prolonged use of PPIs may lead to low magnesium levels in the body; hence regular blood tests might be necessary during long-term treatment.
How much do Prevacid and Nexium cost?
For the brand name versions of these drugs:
- The price of 30 tablets of Prevacid (15 mg) averages around $200, which works out to approximately $6.67/day.
- The price for 30 capsules of Nexium (20 mg) averages about $240, working out to roughly $8/day.
Thus, if you are taking a standard dose for either drug, then brand-name Prevacid is less expensive on a per-day treatment basis. Please remember that cost should not be the primary factor in determining which of these drugs is right for you.
For the generic versions of Prevacid (lansoprazole) and Nexium (esomeprazole), costs are significantly lower:
- Lansoprazole can be purchased in packs ranging from 14 to 1000 capsules with average prices between $0.50 and $1.50 per day depending on dosage and pack size.
- Esomeprazole also comes in packages starting at 14 up to several hundred pills with prices averaging between $.60 and $.80 per day based on dosage amount and quantity purchased upfront.
Popularity of Prevacid and Nexium
Lansoprazole, in generic form as well as brand names such as Prevacid, was estimated to have been prescribed to about 8.1 million people in the US in 2020. Lansoprazole accounted for just over 17% of proton pump inhibitor (PPI) prescriptions in the US. It's a popular choice for treating conditions that involve excessive stomach acid such as Zollinger-Ellison syndrome and gastroesophageal reflux disease (GERD). The prevalence of lansoprazole has remained fairly constant since its introduction.
Esomeprazole, including brand versions such as Nexium, was prescribed to an estimated 14 million people in the USA in 2020. In the US, esomeprazole accounts for nearly a quarter of all PPI prescriptions and is one of the most widely used drugs within this class due to its effectiveness and tolerability profile for managing acid-related disorders. Its usage continues to rise steadily due both to increasing incidence of GERD and its status on many healthcare providers' preferred drug lists.
Conclusion
Both Prevacid (lansoprazole) and Nexium (esomeprazole) are commonly used proton pump inhibitors that decrease the amount of acid produced in the stomach. These medications have a long-standing history of usage for the treatment of conditions like gastroesophageal reflux disease, peptic ulcers, and Zollinger-Ellison syndrome.
These drugs share similar mechanisms of action but tend to be prescribed under different circumstances due to subtle differences in their pharmacokinetics and potency. Nexium is often considered more potent than Prevacid; however, individual responses may vary greatly, making it difficult to categorically state one drug as superior over another.
Both medicines are available in generic form which represents significant cost savings especially for patients who must pay out-of-pocket. It's important to mention that these medications start working within an hour but may require several days before they reach their full effect.
The side-effect profile between both drugs is quite similar with common adverse effects including headache, diarrhea, nausea or abdominal pain. However, because they reduce stomach acid production significantly over time, there's a risk of vitamin B12 deficiency if taken on a long-term basis. As always with medication use, patients should consult with healthcare providers closely when starting either treatment and seek medical help immediately if any severe adverse reactions occur.
