Preventive medicines are used to avoid severe or chronic
headaches, such as migraines or cluster headaches. They are not used to treat
headaches after they begin.
Examples of preventive medicines are:
Calcium channel blockers.
In order for these medicines to work, you will need
to use them exactly as your doctor tells you to. You may need to take them daily even when you do not have a headache. Some people only have
to take preventive medicines for a few months. Other people need to take them
long-term. Botulinum toxin is given as multiple shots every 12 weeks.
