Headaches

Headaches are a common side effect characterized by pain in the head, ranging from mild to severe, potentially accompanied by nausea and sensitivity to light/sound. They can be triggered by various factors, including dehydration, stress, or medication.

Headaches, characterized by pain in the head, can range from mild tension headaches to severe migraines. They can manifest as throbbing, constant, sharp, or dull pain, and may be localized or felt throughout the head. Associated symptoms may include nausea, vomiting, sensitivity to light (photophobia), and sensitivity to sound (phonophobia). Headaches can be triggered by various factors including dehydration, stress, lack of sleep, certain foods and beverages, caffeine withdrawal, changes in weather, and underlying medical conditions. Medication-induced headaches are also possible as a side effect from pharmaceuticals. The pathophysiology can involve changes in brain chemicals, blood vessel activity, and nerve signaling.
