Tadalista 40 mg (which contains tadalafil) can help some people with nerve-related erectile dysfunction (ED), but its effectiveness depends on the extent and cause of the nerve damage. Here's how it works: Tadalafil relaxes blood vessels and increases blood flow to the *****. It does not repair damaged nerves or restore nerve function. If the nerves still provide enough signaling to trigger an erection, the improved blood flow may make it easier to achieve and maintain one. It may be helpful in conditions such as: Mild to moderate diabetic nerve damage. Some men recovering from nerve-sparing prostate surgery. Certain spinal cord injuries where some erectile nerve pathways remain intact. It is less likely to work well if: The nerve damage is severe or complete. The nerves responsible for initiating erections have been extensively damaged or removed. A 40 mg dose is relatively high. Standard tadalafil dosing for ED is: 10–20 mg taken as needed before ***** activity, or 2.5–5 mg once daily. A 40 mg dose may increase the likelihood of side effects such as headache, flushing, nasal congestion, muscle or back pain, dizziness, or low blood pressure. It should only be taken if it has been specifically prescribed for you. If nerve-related ED does not respond adequately to tadalafil, other treatments may be considered, including vacuum erection devices, penile injections, or penile implants, depending on the underlying cause and severity.
