Oral corticosteroids reduce absorption of calcium and interfere with the activation and metabolism of the vitamin, increasing the risk of bone loss. Doctors can measure levels of activated vitamin D (called 1,25 dihydroxycholecalciferol) to determine whether a deficiency exists; if so, activated vitamin D is only available by prescription. A study of rheumatoid arthritis patients treated with low amounts of prednisone found that those who received 1,000 mg of calcium per day plus 500 IU of vitamin D per day for two years experienced no bone loss during that time period. An analysis of properly conducted trials concluded that supplementation with vitamin D and calcium was more effective than placebo or calcium alone in protecting against corticosteroid-induced osteoporosis. Most doctors recommend 1,000 mg of calcium and 400–800 IU vitamin D per day for the prevention of osteoporosis.

This interaction is based on this drug belonging to a drug class. While this drug may differ from the text and references below, drugs within this class work in a similar way and this interaction is applicable to drugs within the same class.

Preliminary data suggest that corticosteroid treatment increases chromium loss. Double-blind trials are needed to confirm these observations.

A controlled trial found that a single dose of the synthetic corticosteroid dexamethasone suppressed production of melatonin in nine of 11 healthy volunteers. Further research is needed to determine if long-term use of corticosteroids interferes in a meaningful way with melatonin production, and whether supplemental melatonin would be advisable for people taking corticosteroids.

Oral corticosteroids increase the urinary loss of potassium. This may not cause a significant problem for most people. Individuals who wish to increase potassium intake should eat more fruits, vegetables, and juices rather than taking over-the-counter potassium supplements, which do not contain significant amounts of potassium.

Corticosteroids may increase the loss of vitamin B6. One double-blind study of people with asthma failed to show any added benefit from taking 300 mg per day of vitamin B6 along with inhaled steroids. Therefore, while small amounts of vitamin B6 may be needed to prevent deficiency, large amounts may not provide added benefit. Some doctors recommend that people taking corticosteroids for longer than two weeks supplement with at least 2 mg of vitamin B6 per day.

Oral corticosteroids have been found to increase urinary loss of vitamin K, vitamin C, selenium, and zinc. The importance of these losses is unknown.

According to preliminary human studies, horny goat weed offset some of the side effects of corticosteroids.

When applied to the skin, glycyrrhetinic acid (a chemical found in licorice (Glycyrrhiza glabra)) increases the activity of hydrocortisone. This effect might allow for less hydrocortisone to be used when combined with glycyrrhetinic acid, but further study is needed to test this possibility.

One preliminary study found that in people with fibrosing alveolitis (a rare lung disease), supplementation with 600 mg N-acetyl cysteine three times per day increased the effectiveness of prednisone therapy.

Children with alopecia areata who supplemented 100 mg of zinc and 20 mg biotin each day, combined with topical clobetasol, showed more improvement compared to children who took oral corticosteroid drugs. Controlled research is needed to determine whether adding oral zinc and biotin to topical clobetasol therapy is more effective than clobetasol alone. However, until more information is available, caregivers should consider that children with alopecia who are currently taking oral corticosteroids might benefit from switching to supplements of zinc and biotin along with topical clobetasol.

Preliminary data suggest that supplementation with chromium (600 mcg per day in the form of chromium picolinate) may prevent corticosteroid-induced diabetes. Double-blind trials are needed to confirm these observations.
