Complications
Headache that develops alongside motion sickness or as a component of it may be stress-related, migrainous, or similar in some way to migraine that has not been fully elucidated.[95] In all cases, relief of the headache components may help alleviate the malaise associated with motion sickness. The antihistamines (e.g., dimenhydrinate) and antimuscarinics (e.g., scopolamine) that remain the standard, most effective treatment for motion sickness do not address its headache component.
Simple painkillers may be effective. However, in more intransigent cases, similarities between the symptoms of motion sickness and migraine, together with the elevated risk of motion sickness in migraineurs, suggest that medications used to treat migraine could be effective for motion sickness.
