Which is more effective pseudoephedrine sulfate vs pseudoephedrine hcl?

Wrong choice. No clinical difference in the decongestant effect. But the effect is due to vasoconstriction of the blood vessels in sinuses and nose, which is followed by rebound worsening of congestion and systemic side-effects including hyertension, tremors, anxiety, even stroke. For nasal congestion, one should use an inhaled steroid, eg, Flonase (fluticasone nasal) spray; it treats sinuses and nose better.
