Formulations have been developed administering a guaiacolsulfonate salt, preferably potassium salt, in multi-phases. In a preferred embodiment, the formulation contains potassium guaiacolsulfonate in an immediate release ("IR") form and a sustained or delayed release ("DR") form and/or pulsed release ("PR") form. In another embodiment, the potassium guaiacolsulfonate is released in a gradient, decreasing the side effects associated with rapidly elevated blood levels. In another embodiment, the drug is bound to an ion-exchange resin, which can be suspended in a liquid or incorporated into a matrix for delayed, sustained and/or pulsed release. Dosage unit forms may be tablets, gels, liquids, capsules, beads, microparticles, films or lozenges. Multi-phase delivery can also be achieved through the use of a kit that provides for dosage escalation. The formulations are useful in the treatment of one or more symptoms of coughs, colds, sinusitis and other respiratory illnesses. The formulations are also useful in the treatment or relief of fibromyalgia, pain, and Irritable Bowel Syndrome
