Patent Claims:1. A method of treating or reducing incidence of headache in a subject comprising administering to the subject a monthly dose of a monoclonal antibody that inhibits the calcitonin gene-related peptide (CGRP) pathway, wherein the amount administered monthly is between 100-900 mg, and wherein the monoclonal antibody comprises a CDR H1 as set forth in SEQ ID NO:3; a CDR H2 as set forth in SEQ ID NO:4; a CDR H3 as set forth in SEQ ID NO:5; a CDR L1 as set forth in SEQ ID NO:6; a CDR L2 as set forth in SEQ ID NO:7; and a CDR L3 as set forth in SEQ ID NO:8.

2. The method of claim 1, wherein the headache is migraine headache.

3. The method of claim 2, wherein the migraine headache is chronic migraine headache.

4. The method of claim 2, wherein the migraine headache is episodic migraine headache.

9. The method of claim 1, wherein the amount of the monoclonal antibody administered in a first month is different than the amount of the monoclonal antibody administered in a second month.

10. The method of claim 9, wherein the amount of the monoclonal antibody administered in the first month is higher than the amount of the monoclonal antibody administered in the second month.

11. The method of claim 1, wherein the administering is subcutaneous or intravenous administration.

12. The method of claim 1, wherein the administering comprises utilizing a pre-filled syringe comprising the amount of the monoclonal antibody.

13. The method of claim 1, wherein the monoclonal antibody is formulated at a concentration of at least 150 mg/mL.

14. The method of claim 1, wherein the monoclonal antibody is administered in a volume of less than 2 mL.

15. The method of claim 1, comprising administering to the subject a second agent simultaneously or sequentially with the monoclonal antibody.

16. The method of claim 15, wherein the second agent is selected from the group consisting of: 5-HT1 agonists, triptans, ergot alkaloids, and non-steroidal anti-inflammatory drugs.

17. The method of claim 15, wherein monthly use of the second agent by the subject is decreased by at least 15% after administering the monoclonal antibody.

18. The method of claim 15, wherein the second agent is a triptan.

19. The method of claim 1, wherein the subject is human.
