Interactions with Drugs

It has been noted that dexpanthenol may increase bleeding time and therefore potentially increase the risk of bleeding when combined with other agents with similar properties. However, there is limited evidence in this area, and this is generally not regarded as a serious potential risk.

In theory, pantothenic acid and dexpanthenol may increase the effects of cholinesterase inhibitor drugs (including multiple Alzheimer's drugs) by increasing production of acetylcholine, leading to potentially dangerous side effects. Examples of cholinesterase inhibitors include: donepezil (Aricept®), rivastigmine (Exelon®), galantamine (Reminyl®), tacrine (Cognex®), neostigmine (Prostigmin®), edrophonium chloride (Tensilon®), and pyridostigmine bromide (approved by the U.S. Food and Drug Administration (FDA) for use after exposure to the nerve gas Soman). Combining these agents should be avoided unless under strict medical supervision.

Drugs containing estrogen and progestin may increase the daily requirement of pantothenic acid.

Interactions with Herbs and Dietary Supplements

High doses of pantothenic acid may inhibit the absorption of biotin produced by microflora in the large intestine.

It has been noted anecdotally that dexpanthenol may increase bleeding time and therefore potentially may increase the risk of bleeding when combined with other agents with similar properties. However, there is limited evidence in this area and this is generally not regarded as a serious potential risk. Multiple cases of bleeding have been reported with the use of Ginkgo biloba, and fewer cases with garlic and saw palmetto. Numerous other agents may theoretically increase the risk of bleeding, although this has not been proven in most cases.

Estrogen and progestin may increase the body's daily requirement for pantothenic acid.
