Dehydration or illness can lead to chapped lips and other lip issues, but certain medications may also be responsible.

For many, lips are also a symbol of beauty. When lips become dry, chapped, or develop sores, it can be uncomfortable and unsightly. While dehydration or infections can cause these issues, certain medications may also lead to such side effects.
Chapped lips, while not severe, can be quite bothersome. Similarly, acne can be a nuisance. Accutane, a widely used acne medication, can clear your skin but comes with various side effects, including chapped lips [source: WebMD]. Other medications, such as topical creams with benzoyl peroxide, Retin-A, or salicylic acid, may also cause dry, chapped lips [source: Taylor]. If you notice lip dryness after starting a new medication, inform your doctor. While lip balm often helps, persistent or worsening symptoms may require a change in medication.
Mouth and lip sores can be a side effect of various medications, including strong chemotherapy treatments. Even common drugs like aspirin and penicillin may cause similar issues. These sores can be painful and take days to heal. To ease discomfort, consider using painkillers or applying ice to numb the area [source: Hurd].
When starting a new medication, including vitamins or supplements, monitor how your body reacts. If you notice unusual symptoms, consult your doctor. While dry, chapped lips or sores might seem minor, they should not be overlooked.
