Is Caffeine good or bad for migraine?

Caffeine has a unique relationship with migraines. It's a common ingredient in many over-the-counter and prescription migraine medications, which suggests its effectiveness as a treatment. However, people with migraines are often advised to avoid caffeine. So, what's the truth? Let's shed some light on this matter.

Caffeine as a treatment for migraine

Caffeine is included in many migraine treatments because it can be effective in relieving migraine symptoms. When a migraine occurs, certain neurotransmitters released by the brain's sensory system cause vasodilation. Caffeine acts as a vasoconstrictive agent, counteracting the effects of these neurotransmitters. This, in turn, reduces the sensitivity of nerves involved in migraines and can lead to shorter and less severe migraine attacks.

Caffeine can also be useful in treating other headache disorders. For example, it may help regulate the areas of the brain that control the production of spinal fluid, making it beneficial for certain types of headaches known as "spinal" headaches. Additionally, it's used to treat Hypnic Headache, which wakes you up with headache pain at the same time every day.

Why caffeine isn't ideal for migraine

While caffeine can provide relief for migraines, excessive consumption can lead to mood disturbances, sleep disruptions, and changes in appetite, making it more likely for these triggers to provoke a migraine. Excessive caffeine intake is typically considered more than 200mg per day, which is roughly equivalent to two cups of brewed coffee. However, it's crucial to note that caffeine content can vary depending on coffee type and brewing methods.

Like many migraine treatments, moderation is key with caffeine. Overusing any migraine medication can lead to medication overuse headaches or "rebound" headaches. So, it's crucial to keep track of how often you use caffeine-containing medications and other migraine treatments to avoid exacerbating your migraines unintentionally.

Caffeine withdrawal is also a common migraine trigger. If you are accustomed to a certain amount of caffeine and then suddenly decrease or stop its intake, you might trigger a headache. In such cases, your doctor can recommend strategies to help you wean off caffeine gradually without provoking headaches.


In conclusion, caffeine and migraines have a complicated relationship. While caffeine can help alleviate migraines and certain headache disorders, excessive consumption or sudden withdrawal can worsen symptoms. For those with migraines, it's generally recommended to limit caffeine intake to less than 200mg per day, unless caffeine itself acts as a trigger for their migraines, in which case complete avoidance may be necessary.

Always be attentive to how your body reacts to caffeine and keep track of your caffeine intake. If you are unsure about caffeine's impact on your migraines, it's a good idea to consult with a doctor or migraine specialist. They can help you develop a personalized plan and suggest appropriate strategies to manage your migraines effectively.

Remember, every individual's response to caffeine can differ, so it's essential to listen to your body and be mindful of its effects on your migraine condition.
