Tadalafil does not treat cavernous atrophy. Tadalafil is used to treat erectile dysfunction disorders in men. Cavernous atrophy may be caused by insufficient blood supply to the corpus cavernosum or a lack of androgens, and is not considered erectile dysfunction. Taking tadalafil alone does not treat the condition, but may instead produce adverse effects such as headaches, muscle pain, and dizziness. Patients need sexual stimulation to make tadalafil effective and should not take the drug continuously to prevent damage to the body. It is contraindicated in people who are allergic to the drug, hereditary galactose intolerance, refractory arrhythmias, etc. Patients with cavernous atrophy should go to the hospital in a timely manner, to clarify the specific cause of the disease, and according to the results of the examination to choose the appropriate drug treatment, it is not recommended to take tadalafil on their own to prevent damage to the body.
