Although not proven that Robaxin is effective for headaches but, some clinical experiments suggest that Robaxin, when combined with other medications, can be effective on headaches.

A seventy-five-year-old, 60 kg woman without significant medical history, presented to the Long Island College Hospital Emergency Department with an acute inferior wall MI in 1990.

The patient was discharged from the hospital on day five with a regimen of isosorbide dinitrate, diltiazem, metoprolol, and aspirin.

The patient remained well until November, 1990, when she began to experience headaches. By February, the patient felt well except for an occasional headache, which responded to acetaminophen.Isosorbide dinitrate was discontinued.

In early June, the patient noticed an increase in frequency and intensity of the headache, and more disturbing was a charge in its character, which was described as a bitemporal squeezing with radiation to the sternocleidomastoid muscles bilaterally.

Methocarbamol and acetaminophen were prescribed. By late June the headaches were intolerable, now associated with dizziness, and the patient underwent CT of the brain which disclosed a large left SDH.There was no history of head trauma, alcohol abuse, or seizure disorder (Case Report).
