Final answer:
Early intervention with abortive medication is crucial for migraine or cluster headaches, and alcohol can exacerbate these conditions by causing vasodilation.
Step-by-step explanation:
When dealing with a migraine or a cluster headache in its early phase, abortive medication therapy should be instituted as soon as possible. This approach helps in preventing the headache from reaching a more severe stage, thus reducing unnecessary pain. Additionally, certain substances like alcohol can trigger or worsen headaches by causing vasodilation of the blood vessels. Therefore, understanding and addressing these factors promptly can significantly improve treatment outcomes for individuals experiencing such headaches.
