Priapism should be treated according to established medical practice. One algorithm aimed primarily at treating priapism secondary to pharmacological agents is presented below: Procedure 1 – External Perineal Compression: Although frequently unsuccessful, the use of prolonged external perineal compression, including ice, may be applied as a temporizing measure.

Place the patient in the supine position and assure local anesthesia of the penis. The penile shaft should be punctured at either the 2 o’clock or the 10 o’clock position, and 20-30 mL of blood aspirated from the corpus cavernosum. If detumescence has occurred, the penis should be dressed with an elasticized bandage to ensure continued emptying of the corpora and to compress the puncture site(s).
If procedure 2 is unsuccessful, proceed to procedure 3. 2 mL every 2-5 minutes, for up to 10 doses). Clinicians should refer to the prescribing information for phenylephrine prior to its use. If the above algorithm fails to achieve detumescence in the patient, a urologist should be consulted immediately.
Penile tissue damage and/or permanent loss of potency may result if priapism is not treated immediately. ACTION AND CLINICAL PHARMACOLOGY Tadalafil is a potent, selective, reversible inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5).
