Patients with migraines can appropriately drink some white liquor or beer, which is generally not a problem, but they must not drink red wine. This is because red wine and dairy products, such as cheese, can induce migraine attacks. Additionally, pickled foods like pickled vegetables contain nitrites, which can also trigger migraine attacks; therefore, it is best to avoid pickled foods as much as possible. Typically, before a migraine attack, there is a precursor symptom where vision changes occur. After these precursor symptoms disappear, migraine symptoms emerge. During a migraine attack, oral pain relievers can be taken for symptomatic treatment. Some patients may find relief on their own a few hours after not taking medicine. Symptoms may recur, so it is generally advised to identify and avoid these triggers to prevent migraine attacks.
