Which medication is known to cause photosensitivity?

Amiodarone is well-documented for its side effect of photosensitivity, which makes individuals more susceptible to sunburn and rashes upon exposure to sunlight. This reaction occurs due to the accumulation of the drug in the skin and its interaction with UV radiation, leading to adverse skin reactions. Patients taking amiodarone are often advised to take precautions when exposed to sunlight, such as wearing protective clothing and using sunscreen, to mitigate this risk.

While medications like metformin, omeprazole, and aspirin have their own potential side effects, they are not commonly associated with photosensitivity in the same way that amiodarone is. Metformin is primarily used for diabetes management, omeprazole is a proton pump inhibitor for gastric issues, and aspirin is an anti-inflammatory and pain relief medication. These medications do not typically increase sensitivity to sunlight, which highlights the distinct profile of amiodarone's side effects.
