Mineral Oil Shortage: What Providers and Prescribers Need to Know in 2026

Mineral oil is a decades-old OTC lubricant laxative that remains in use for specific clinical indications. As newer osmotic and stimulant laxatives have come to dominate constipation management guidelines, mineral oil's role has narrowed — but it retains utility in select patient populations. Here is what clinicians and prescribers need to know about its current supply status, clinical profile, and when to recommend alternatives.

Supply Status in 2026

Mineral oil is not on the FDA Drug Shortage database as of 2026. It is regulated as an OTC drug under FDA Monograph M007 (Laxative Drug Products for Over-the-Counter Human Use) and is manufactured by several companies, including C.B. Fleet Company (Fleet brand) and Konsyl Pharmaceuticals (Kondremul). Multiple store-brand generics are also widely produced.

Some pharmacies have reduced shelf space devoted to mineral oil as PEG 3350 (MiraLax) has become the dominant OTC laxative. Patients may encounter localized out-of-stock situations at smaller pharmacies or in certain retail environments. Advising patients to check multiple locations or use a medication locator service will typically resolve the issue quickly.

Clinical Profile: Mechanism and Indications

Mineral oil is a complex mixture of saturated hydrocarbons derived from crude petroleum, refined for human use by removing aromatic amines and unsaturated hydrocarbons. When taken orally, it:

Retards reabsorption of water from the intestinal lumen

Lubricates fecal material and intestinal mucosa

Eases passage of stool without stimulating muscle contractions

Laxative effect occurs 6–8 hours after oral administration and within 5–15 minutes following rectal administration. Absorbed mineral oil distributes into mesenteric lymph nodes, intestinal mucosa, liver, and spleen.

FDA-approved OTC indications:

Occasional constipation (irregularity)

Pre-procedure bowel preparation (rectal enema form)

Constipation associated with colonic stricture or hard, dry stools (when bulk-forming agents are impractical)

Contraindications and High-Risk Populations

The primary safety concern with oral mineral oil is aspiration and resultant lipoid pneumonia. This risk is heightened in:

Elderly or debilitated patients with impaired swallowing or epiglottal function

Bedridden patients

Neurologically impaired children (case reports of lipoid pneumonia from aspiration)

Patients with dysphagia, esophageal conditions, hiatal hernia, or gastric retention

Additional contraindications include:

Oral use during pregnancy (impairs maternal absorption of fat-soluble vitamins A, D, E, K)

Abdominal pain, nausea, or vomiting suggesting acute abdomen

Known or suspected fecal impaction with obstruction, appendicitis, intestinal perforation, colostomy, ileostomy, ulcerative colitis, or diverticulitis

Children under 6 (oral) or under 2 (rectal)

Drug Interactions Clinicians Should Know

Docusate: Contraindicated concurrently — docusate emulsifies mineral oil, increasing systemic absorption and risk of lipoid pneumonia.

Warfarin: Chronic mineral oil use impairs vitamin K absorption, potentially altering anticoagulation. Monitor INR carefully.

Fat-soluble vitamins (A, D, E, K): Prolonged use reduces absorption — clinically significant with extended use.

Digoxin: May reduce digoxin absorption — advise 2+ hour separation.

Oral contraceptives, many other oral medications: General recommendation to take other medications at least 2 hours before or after mineral oil.

Clinical Alternatives to Recommend

For most patients, especially those in high-risk categories for mineral oil use, the following alternatives are preferred:

PEG 3350 (MiraLax): First-line osmotic laxative; no aspiration risk; robust evidence base; safe in elderly patients

Docusate sodium (Colace): Preferred post-surgical stool softener; safe in pregnancy; do not combine with mineral oil

Senna: Effective stimulant laxative; appropriate for short-term use; commonly combined with docusate post-operatively

Psyllium (Metamucil): Bulk-forming fiber supplement; preferred for long-term chronic constipation management

How to Help Patients Locate Mineral Oil

If you're recommending mineral oil for a patient and they're having trouble finding it, medfinder for providers is a service that calls local pharmacies on the patient's behalf to find which ones have their medication in stock, then texts results to the patient. This reduces follow-up calls to your office from patients who can't locate their medication.
