Single doses up to 500 mg have been given to healthy male subjects, and multiple daily doses up to 100 mg have been given to male patients with erectile dysfunction. Adverse reactions were similar to those seen at lower doses. Doses greater than 40 mg have not been studied in patients with pulmonary arterial hypertension. In cases of overdose, standard supportive measures should be adopted as needed. Hemodialysis contributes negligibly to tadalafil elimination.
Concomitant Organic Nitrates
Do not use ADCIRCA in patients who are using any form of organic nitrate, either regularly or intermittently. ADCIRCA potentiates the hypotensive effect of nitrates. This potentiation is thought to result from the combined effects of nitrates and ADCIRCA on the nitric oxide/cGMP pathway [see CLINICAL PHARMACOLOGY].
Concomitant Guanylate Cyclase (GC) Stimulators
Do not use ADCIRCA in patients who are using a GC stimulator, such as riociguat. ADCIRCA may potentiate the hypotensive effects of GC stimulators.
ADCIRCA is contraindicated in patients with a known serious hypersensitivity to tadalafil (ADCIRCA or CIALIS). Hypersensitivity reactions have been reported, including Stevens-Johnson syndrome and exfoliative dermatitis [see ADVERSE REACTIONS].This monograph has been modified to include the generic and brand name in many instances.
