Tag: Drug induced ptosis

Following botulinum toxin A injections for facial aesthetics, eyelid ptosis has a reported incidence of around 2.5% to 3.1% [1.3.1, 1.3.6]. This highlights just one example of how certain drugs can lead to a droopy eyelid, but **what medications can cause ptosis?**

Studies suggest that the prevalence of undiagnosed ptosis in adults can be as high as 13.7% [1.10.3]. While often associated with aging, it's crucial to ask: **what drugs can cause ptosis?** A surprising number of common medications can be a contributing factor.

While most people associate ptosis, or drooping eyelids, with aging or congenital conditions, a variety of medications can also cause it as a side effect. This can occur when drugs interfere with the complex neuromuscular functions that control eyelid movement, leading to weakness or paralysis of the levator muscle.
