What adverse effect is commonly associated with Tetracycline?

Tetracycline is an antibiotic that is well-known for increasing the skin's sensitivity to sunlight, a condition known as photosensitivity. This adverse effect occurs because tetracycline can affect the skin's ability to protect itself from ultraviolet (UV) radiation. Patients taking this medication are often advised to avoid excessive sun exposure, wear protective clothing, and use sunscreen to minimize the risk of sunburn and skin damage.

The other options, while they may relate to side effects of certain medications, are not typically associated with tetracycline. For example, severe allergies and digestive issues can occur with many medications but are not specifically linked to tetracycline as common adverse reactions. Similarly, while liver damage is a potential risk with some antibiotics, tetracycline is not primarily known for this effect. Thus, the most accurate and commonly associated adverse effect of tetracycline is its tendency to increase susceptibility to sun exposure.
