What should you know about nicotine headache?

Nicotine can alter blood-vessel tone and stimulation, while a drop in nicotine after regular use may bring withdrawal symptoms such as headache, irritability and difficulty concentrating. Headache may also come from dehydration, missed meals, poor sleep, heat, infection, sinus inflammation or anxiety. The presence of a headache alone does not identify one cause. Note when it begins in relation to nicotine, food, fluids, sleep and outdoor heat, along with its location and severity.

Rest in a quiet, cool place, drink fluids if you can, eat a regular meal and avoid changing nicotine use abruptly without a plan if you use it often. Keep a brief symptom diary and follow label directions for any suitable pain medicine. If headaches recur, a clinician can review medicines, blood pressure, vision, sleep and possible causes such as Allergic Rhinitis, Chronic Sinusitis, Common Cold or Dehydration.

Seek emergency care for a sudden, severe headache; headache after a head injury; new weakness, numbness, confusion, seizure, fainting, trouble speaking or vision loss; or fever with a stiff neck. Prompt assessment is also sensible for a new persistent pattern, repeated vomiting, pregnancy-related headache or headache after significant heat exposure. Fever and severe body aches may require evaluation for infections such as COVID-19 or Dengue Fever, while dizziness, heavy sweating and weakness can occur with Heat Exhaustion.

Ask whether the timing suggests nicotine use or withdrawal, which pain relief is appropriate for you, and whether your symptoms need examination or testing.
