EFFECTIVE

• Pantothenic acid deficiency. Taking pantothenic acid 5-10 mg daily is effective for treating and preventing pantothenic acid deficiency (15).

POSSIBLY INEFFECTIVE

• Radiation dermatitis. Topical dexpanthenol does not seem to be beneficial for preventing or treating radiation dermatitis. Details: Applying dexpanthenol, an analog of pantothenic acid, twice daily to areas of irradiated skin does not seem to reduce erythema, desquamation, itching, or pain following radiation treatment (7192). Also, applying dexpanthenol 0.5% cream (Bepanthen, Hoffmann LaRoche ) daily during radiation therapy and for 2 weeks after completing radiation therapy is less effective than methylprednisolone aceponate 0.1% cream (Advantan) at reducing radiation-induced skin irritation (67779).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Acne. Oral or topical pantothenic acid has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In adults with mild to moderate acne, clinical research shows that taking a specific supplement (Pantothen, Avilan Marketing LLC) providing pantothenic acid 1.1 grams twice daily in addition to other B vitamins for 12 weeks modestly reduces total and non-inflammatory lesion counts when compared with placebo (105188). Also, in adolescents or young adults with mild to moderate acne, preliminary clinical research shows that topical application with a gel containing D-panthenol 4%, hydrogen peroxide 4%, and salicylic acid 0.5% once daily for 60 days modestly reduces acne lesions when compared with baseline (105189). The validity of this finding is limited by the lack of a comparator group.
• Alcoholism. Although there is interest in using oral pantothenic acid for improving recovery from alcoholism, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Allergic rhinitis (hay fever). Although there is interest in using oral pantothenic acid for allergic rhinitis, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Alopecia areata. Pantothenic acid has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in healthy adults with diffuse hair loss shows that intramuscular administration of dexpanthenol 250 mg and biotin 5 mg once weekly for 6 weeks reduces hair fall count at weeks 1 and 8, but only increases hair density at week 1, when compared to baseline (111366). The validity of these findings is limited by the study's small size, short duration, and lack of comparator group.
• Anxiety. Although there is interest in using oral pantothenic acid for anxiety, there is insufficient reliable information about the clinical effects of pantothenic acid for this purpose.

• Attention deficit-hyperactivity disorder (ADHD). Oral pantothenic acid has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Some small outdated clinical studies in children diagnosed with hyperkinesis suggest that taking calcium pantothenate 1.2 grams, alone or in combination with niacinamide, ascorbic acid, and pyridoxine, does not improve symptoms of hyperactivity when compared with placebo (3351,9957). It is unclear what effects pantothenic may have, if any, in children with a modern diagnosis of ADHD.
• Atopic dermatitis (eczema). It is unclear if topical pantothenic acid is beneficial in infants or children with atopic dermatitis. Details: One preliminary clinical trial in infants and children with stable mild atopic dermatitis shows that topical application of an emollient containing panthenol (Bepanthen, SensiDaily, Bayer Consumer Care AG) for 3 months is as effective as a reference emollient for reducing symptoms and preventing a flare. However, the efficacy of the reference emollient (Stelatopia Emollient Cream, Mustela; Laboratoires Expanscience) is unclear based on available preliminary clinical research (105190).
• Autism spectrum disorder. Although there is interest in using oral pantothenic acid for autism spectrum disorder, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.

• Dry eye. Although there is interest in using ocular pantothenic acid for dry eye, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Dry skin. It is unclear if topical dexpanthenol is beneficial for patients with dry skin. Details: A small, open-label study in healthy adults with dry skin shows that cleansing the skin with a dexpanthenol-containing liquid cleanser (DCLC, Bepanthen SensiControl Daily Gentle Body Wash) daily for 4 weeks increases stratum corneum hydration by 17% without affecting skin barrier function, pH, or microbiome when compared to baseline (111262). The validity of these findings is limited by the lack of blinding and a comparator group.
• Epilepsy. Although there is interest in using oral pantothenic acid for epilepsy, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Eye trauma. It is unclear if ocular dexpanthenol is beneficial for eye trauma. Details: Some preliminary clinical research shows that using eyedrops containing dexpanthenol 5%, a derivative of pantothenic acid, two drops four times daily for 28 days following surgery for retinal detachment reduces eye pain and discomfort when compared with placebo drops (67783). However, using a specific dexpanthenol 5% ointment (Bepanthen) does not seem to improve corneal epithelial wound healing following phototherapeutic keratectomy when compared with placebo (67801).
• Heart failure. Although there is interest in using oral pantothenic acid for heart failure, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Herpes zoster (shingles). Although there is interest in using oral or topical pantothenic acid for shingles, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Insomnia. Although there is interest in using oral pantothenic acid for insomnia, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Laser skin resurfacing. It is unclear if topical dexpanthenol or pantothenic acid can reduce adverse effects after laser skin resurfacing procedures. Details: A preliminary clinical study shows that use of a dexpanthenol-containing ointment (Bepanthen Wound Healing Ointment, Bayer) once daily modestly reduces the diameter of lesions up to 3 days after fractional carbon dioxide laser resurfacing when compared with petroleum jelly (105743). Also, applying a specific cream (Cicaplast Baume B5 cream, L'Oreal) containing panthenol 5%, madecassoside, copper, zinc, and manganese to one side of the face for 28 days reduces decrustation time by approximately one day when compared with a control emollient. Redness and swelling were lower at 3 days, but there was no difference in pain and burning (105742). It is unclear if these effects are due to pantothenic acid, other ingredients, or the combination.
• Multiple sclerosis (MS). Although there is interest in using oral pantothenic acid for MS, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Muscular dystrophy. Although there is interest in using oral pantothenic acid for muscular dystrophy, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.

• Pain (chronic). It is unclear if oral or topical pantothenic acid is beneficial for the management of various forms of chronic pain. Details: Although there is interest in using oral or topical pantothenic acid for various forms of chronic pain, including neuropathy and arthritis, there is limited information available about the clinical effects of pantothenic acid for this purpose. One review of preliminary clinical research found that calcium pantothenate does not reduce symptoms of arthritis in patients with rheumatoid arthritis or osteoarthritis (10433).
• Parkinson disease. Although there is interest in using oral pantothenic acid for Parkinson disease, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Poison oak and poison ivy dermatitis. Although there is interest in using topical pantothenic acid for poison ivy dermatitis, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Postoperative pain. It is unclear if oral pantothenic acid is beneficial for postoperative pain. Details: In post-tonsillectomy patients aged 5-12 years, preliminary clinical research shows that taking pastilles containing dexpanthenol (Bepanthene, Bayer) 100 mg three times daily reduces pain when compared with placebo. Postoperative pain was modestly reduced at 1, 3, 7, and 14 days after surgery (105191).
• Postoperative sore throat. It is unclear if pantothenic acid lozenges are beneficial for postoperative sore throat. Details: Preliminary clinical research shows that taking two lozenges containing dexpanthenol, an analog of pantothenic acid, 200 mg 30 minutes prior to general anesthesia reduces the incidence and severity of postoperative sore throat when compared with a benzydamine hydrochloride or placebo spray (67792).
• Pregnancy-related leg cramps. Although there is interest in using oral pantothenic acid for pregnancy-related leg cramps, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Premenstrual syndrome (PMS). Although there is interest in using oral pantothenic acid for PMS, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Respiratory tract infections. Although there is interest in using oral pantothenic acid for respiratory tract infections, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Rhinosinusitis. It is unclear if nasal dexpanthenol is beneficial for rhinosinusitis. Details: Preliminary clinical research shows that using a nasal spray (MarPlus) containing dexpanthenol, an analog of pantothenic acid, on the first, second, fourth, and sixth week after endoscopic sinus surgery reduces nasal discharge, but not other symptoms associated with chronic rhinosinusitis, when compared with saline nasal spray (67808).
• Skin irritation. It is unclear if topical dexpanthenol is beneficial for preventing or treating skin irritation due to sodium lauryl sulfate. Details: Preliminary clinical research shows that applying dexpanthenol (Bepanthol Handbalsam), an analog of pantothenic acid, twice daily for 26 days does not prevent sodium lauryl sulfate-induced skin irritation (67785). However, dexpanthenol may be effective for treating skin irritation caused by sodium lauryl sulfate. Use of an ointment containing dexpanthenol 1% to 5% twice daily for up to 30 days following skin exposure to sodium lauryl sulfate seems to reduce skin water loss, skin roughness, and skin inflammation when compared to control (67802,67806).
• Ulcerative colitis. Although there is interest in using oral or rectal pantothenic acid for ulcerative colitis, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Vertigo. Although there is interest in using oral pantothenic acid for vertigo, there is insufficient reliable information about the clinical effects of pantothenic acid for this condition.
• Wound healing. Preliminary clinical research suggests that oral dexpanthenol might be beneficial for wound healing. Details: In post-tonsillectomy patients aged 5-12 years, preliminary clinical research shows that taking pastilles containing dexpanthenol (Bepanthene, Bayer) 100 mg three times daily improves wound healing when compared with placebo. Depending on the type of surgery, wound healing occurred in 2.3-2.9 times as many patients within 7 days of surgery, and in 13% to 35% more patients within 14 days, when compared with placebo (105191). More evidence is needed to rate pantothenic acid for these uses.
