Patients who receive an injection of d-panthenol (dexpanthenol) after abdominal surgery may have allergic reactions if they also take antibiotics, narcotics or barbiturates, according to the U.S. National Library of Medicine. The Food and Drug Administration has not approved d-panthenol for human use in the United States. Dexpanthenol has been approved for use in dogs, cats and horses as a treatment for various disorders.
The drug is used after major abdominal surgery to prevent paralysis of the intestinal muscles. When allergic reactions or hypersensitivity occur, discontinue use of d-panthenol. PubChem explains that d-panthenol injections come in 250-milligram vials, and these shots are only administered by medical professionals. The drug is injected into muscle tissue as opposed to directly into veins to prevent muscle paralysis.
For animals, dexpanthenol is used when there is gastrointestinal distress and when muscle functions are impaired in dogs, cats and horses. In the United States, d-panthenol is only approved for animal usage by a licensed veterinarian, according to drug manufacturer Vedco.
Dexpanthenol is a derivative of vitamin B5, or pantothenic acid. As an oral or topical supplement, the substance has been known to alleviate high cholesterol, help with the healing of burns and aid the treatment of ADHD. These medical claims all received a "C" grade from Healthline Networks in terms of effectiveness for treating these particular ailments.
