In migraine management, rebound headache is best described as a potential side effect of medications.

• A. They are never caused by medications.
• B. They are a potential side effect of medications.
• C. They require hospitalization.
• D. They are prevented by taking only one analgesic dose.

Answer: (B)

Rebound headaches, also called medication-overuse headaches, happen when the medicines used to treat migraines are taken too frequently. This makes the statement that rebound headaches are a potential side effect of medications the best description, because the headache problem stems from the medications themselves—not from the migraine on its own. When analgesics or migraine-specific drugs are used many days per week, the brain’s pain pathways can become sensitized, and headaches can persist or worsen as the drug wears off. The cycle is: take medication for relief, relief is temporary, headache returns as the medicine’s effect fades, leading to more dosing. To prevent this, limit the use of acute migraine medications and seek guidance on tapering the offending drug, while emphasizing preventive strategies for chronic migraine. They are not typically a reason for hospitalization, and simply taking a single dose does not prevent them—the issue is repeated, regular use.
