Treatment for Cluster Headache
Sudafed (pseudoephedrine) is a sympathomimetic amine that acts as a decongestant by stimulating alpha-adrenergic receptors, causing vasoconstriction in nasal and sinus blood vessels. While not a primary treatment for cluster headaches, it may provide some symptomatic relief by reducing inflammation and congestion, potentially alleviating associated nasal symptoms.
