Preventive treatment with different medications helps reduce the number of headaches. These preventative treatments include the following:
- Antidepressants: Antidepressants help treat chronic headaches and anxiety, depression, and sleep apnea. This tricyclic anti-depressant is nortriptyline (Pamelor), used to treat chronic headaches. Other anti-depressants such as selective serotonin reuptake inhibitor (SSRI) and fluoxetine (Prozac, Sarafem, and others) also treat chronic headaches. Still, a placebo is more effective than these medications for headaches.
- Beta-blockers: Drugs such as metoprolol (Lopressor, Toprol-XL), propranolol (Inderal, Innopran XL), and atenolol(Tenormin) are not only helpful in preventing episodic migraine but also helpful in treating high blood pressure.

- Anti-seizure medications: Anti-seizure medications such as gabapentin (Neurontin), topiramate(Topamax, Qudexy XR, others), and divalproex sodium (Depakote) help prevent migraines and daily chronic headaches.
- Botulinum toxin: For people who don’t get relief from the above-given medication, OnabotulinumtoxinA (Botox) injection is an effective option for relieving chronic headaches.
