Pharmacology

Morrhuate sodium causes inflammation of the vein's intima resulting in the formation of a thrombus. Occlusion secondary to the fibrous tissue and the thrombus results in the obliteration of the vein.

Use: Labeled Indications

Treatment of small, uncomplicated varicose veins of the lower extremities

Contraindications

Hypersensitivity to morrhuate sodium or any component of the formulation; arterial disease; acute thrombophlebitis; valvular or deep vein incompetence; bedridden patients; varicosities caused by abdominal or pelvic tumors; patients with systemic diseases (eg, uncontrolled diabetes mellitus, thyrotoxicosis, tuberculosis, neoplasms, asthma, sepsis, blood dyscrasias, and acute respiratory or skin diseases); continued administration following a systemic reaction or an unusual local reaction at the injection site; extensive therapy in severely debilitated or senile patients

Dosing: Adult

Note: A test dose of 0.25-1 mL of a 5% injection may be given (into a varicosity) 24 hours before full-dose treatment.

Full-dose treatment: 50-250 mg, depending on the size and degree of varicosity (50-100 mg for small or medium veins, 150-250 mg for large veins); may be given as multiple injections at one time or in single doses.

Dosing: Geriatric
