A 30-day supply of lansoprazole costs around 20 dollars when purchased through online pharmacies with a prescription. The same amount is available at comparable prices when purchased over the counter without a prescription. Stores such as Walmart carry 30-day supplies of lansoprazole for around 21 dollars, while Target and Kmart carry it for around 25 dollars.
Lansoprazole is the generic name for the drug Prevacid. It is a proton pump inhibitor that aims to limit the stomach's acid production, treat ulcers in the stomach and intestines, stop erosion of the esophagus, and quell conditions like Zollinger-Ellison syndrome, in which the body naturally produces an overabundance of stomach acid. It is commonly purchased over the counter by those who seek relief from frequent heartburn.
Take lansoprazole before eating. If using the liquid version, shake well, and measure the dosage precisely with a medicine cup or syringe. If using the pill form, swallow it whole. If unable to swallow the pill, crush it over a spoonful of soft food, or mix it into 1/4 cup fruit juice.
Those using lansoprazole should consult with a pharmacist if they have liver disease, low magnesium levels or osteoporosis. Avoid the drug until speaking with a doctor if you are experiencing sudden weight loss, nausea, stomach pain, trouble swallowing, or black or bloody stools. Those with metabolic disorders, electrolyte imbalances or continuous heartburn for three months or more should also talk to a doctor before starting a lansoprazole regimen.
