Q: Is it okay to cut a Prilosec OTC 20 mg tablet in two and take just half a day? The package says not to crush or chew.
A: Prilosec OTC (Omax) is used for the treatment of acid reflux. It is in the family of proton pump inhibitors that work by disabling some of the acid producing pumps in the stomach to help relieve the symptoms of acid reflux. The prescribing information on Prilosec OTC states that you should not split the caplet in half because it uses an enteric coating to delay the release of medication until it reaches the small intestine, where it will not be destroyed by the stomach acids. If you break the caplet the coating will not work and this will cause the medication to be ineffective.

Omax is a medication prescribed for the treatment of gastroesophageal reflux disease (GERD); peptic ulcer disease; erosive esophagitis; eosinophilic esophagitis; Zollinger-Ellilson syndrome; and medical conditions associated with gastric acid hypersecretion. In some cases, Omax may also be utilized for the prophylaxis of upper gastrointestinal bleeding (in at-risk populations) and as an adjunct treatment for H. plyori infection.
Historical reports suggest that Omax was first synthesized in the 1970s by chemists employed with the pharmaceutical company “Astra.” After successful clinical trials, Omax received approval in 1988 for use throughout Europe under the trade name “Losec” – and in 1990 for use in the United States under the trade name “Prilosec.”
Though many individuals with gastrointestinal disorders derive noticeable benefit from the ongoing administration of Omax, the medication can sometimes cause unwanted side effects. For this reason, if you’re using Omax, it’s probably a good idea to familiarize yourself with potential side effects and adverse reactions that could emerge during treatment.
Q: Does Prilosec OTC cause gas, bloating, and constipation?
A: Prilosec OTC (Omax) (//www.everydayhealth.com/drugs/prilosec) is in a class of medications called proton pump inhibitors used to treat heartburn and GERD. Prilosec may also be used short term to treat ulcers. (//www.everydayhealth.com/gerd/guide/) Common side effects associated with Prilosec include nausea and diarrhea, headache and stomach pain. A search of prescribing information did list gas and constipation as side effects of Prilosec OTC. This is not a complete list of the side effects associated with Prilosec OTC. Kimberly Hotz, PharmD
For the treatment of GERD and maintenance of healing of erosive esophagitis, the recommended daily dose for pediatric patients 1 to 16 years of age is as follows:
Patient Weight Omax Daily Dose 5
On a per kg basis, the doses of Omax required to heal erosive esophagitis in pediatric patients are greater than those for adults.
Alternative administrative options can be used for pediatric patients unable to swallow an intact capsule .
In patients with chronic renal impairment, whose creatinine clearance ranged between 10 and 62 mL/min/1.73 m², the disposition of Omax was very similar to that in healthy volunteers, although there was a slight increase in bioavailability. Because urinary excretion is a primary route of excretion of Omax metabolites, their elimination slowed in proportion to the decreased creatinine clearance. No dose reduction is necessary in patients with renal impairment.
Q: Can Prilosec cause high blood pressure?
A: Prilosec (Omax) belongs to a class of drugs called proton pump inhibitors (PPIs). PPIs decrease or block the production of stomach acid. Prilosec is used to treat the symptoms of gastroesophageal reflux disease (GERD), to promote healing of erosive esophagitis, and to treat or prevent ulcers. Common side effects of Prilosec include gas, stomach pain, nausea, vomiting, diarrhea, and headache. According to the prescribing information for Prilosec, elevated blood pressure has been reported by people taking the drug in post-marketing experience. Post-marketing experience is after the drug has been approved by the U.S. Food and Drug Administration (FDA). In post-marketing experience, patients voluntarily report if they have the side effect. Because it is voluntary, not everyone decides to report if they have the side effect. So, it is hard to know how often the side effect occurs. It is also hard to know if it is caused by the drug or by some other reason. This is different than side effects reported during clinical trials before the drug is approved by the FDA. In clinical trials, researchers have tight control over how side effects are reported and can determine whether they are likely related to the drug or not. So, elevated blood pressure may or may not be caused by Prilosec, but it has been reported in patients taking the drug. See your doctor for proper evaluation of your blood pressure. Your doctor is best able to guide your treatment decisions based on your specific circumstances. Sarah Lewis, PharmD
The elimination rate of Omax was somewhat decreased in the elderly, and bioavailability was increased. Omax was 76% bioavailable when a single 40 mg oral dose of Omax (buffered solution) was administered to healthy elderly volunteers, versus 58% in young volunteers given the same dose. Nearly 70% of the dose was recovered in urine as metabolites of Omax and no unchanged drug was detected. The plasma clearance of Omax was 250 mL/min (about half that of young volunteers) and its plasma half-life averaged one hour, about twice that of young healthy volunteers.
