Administer intranasally once in the morning, afternoon, and evening (6–8hrs apart) at same time each day. ≥18yrs: 11mg (1 pump per nostril) three times daily (total dose: 33mg daily); check serum testosterone levels periodically as soon as one month after initiation. If severe rhinitis occurs; temporarily discontinue until resolve; use alternative if symptoms persist.

Increased risk for worsening BPH; monitor for signs/symptoms. Evaluate for prostate cancer before starting therapy, and 3–6 months after initiation. Monitor hematocrit prior to initiation, at 3–6 months after starting therapy, then annually; if elevation occurs, withhold until acceptable level. Preexisting cardiac, renal, or hepatic disease (discontinue if edema occurs). Discontinue and evaluate if signs/symptoms of hepatic dysfunction (eg, jaundice) occur.
