Miotics are a class of drugs that can cause contact dermatitis, primarily due to their mechanism of action and the components used in their formulations. These drugs, which are often utilized in the treatment of glaucoma, work by increasing the outflow of aqueous humor from the eye. They can contain preservatives, such as benzalkonium chloride, which are known to be irritating to the skin and can lead to allergic reactions including contact dermatitis.

Contact dermatitis arises when skin comes into contact with a substance that causes an allergic reaction or irritation. Since miotic agents can be applied topically or used in eye drops, users may experience localized skin reactions if they have hypersensitivity to the compound or its additives.

In contrast, the other classes listed—mydriatics, anticholinergics, and beta-blockers—are less commonly associated with causing contact dermatitis, as their primary use is related to different therapeutic effects and applications that do not typically involve extensive skin exposure.
