Vidalista 80 is not a standard or approved dosage of tadalafil. Commonly available dosages for tadalafil include 2.5 mg, 5 mg, 10 mg, 20 mg, 40 mg, and 60 mg. If Vidalista 80 has become available since my last update, it's essential to consult a healthcare professional or pharmacist to ensure its legitimacy and appropriateness for your situation.

Now, regarding the long-term use of standard dosages of tadalafil, such as Vidalista 20 or Vidalista 40, there are a few considerations:

Safety under medical supervision: vidalista 80 mg, when used as prescribed and under the supervision of a healthcare provider, can be safe for long-term use in some individuals. It is essential to have regular check-ups with your doctor to monitor your response to the medication and to address any potential side effects.

Tolerance and effectiveness: Some individuals may develop a tolerance to tadalafil over time, which means the same dosage may become less effective in treating their erectile dysfunction. In such cases, a healthcare professional may adjust the dosage or recommend alternative treatments.

Potential side effects: Like all medications, tadalafil can cause side effects, although not everyone experiences them. Common side effects may include headache, flushing, indigestion, back pain, and muscle aches. Serious side effects are rare but can include sudden vision or hearing loss and an erection lasting longer than four hours (priapism), which requires immediate medical attention.

Interaction with other medications: Tadalafil may interact with certain medications, especially nitrates (often used for chest pain), and alpha-blockers (used for high blood pressure). It's crucial to inform your healthcare provider about all the medications and supplements you are taking to avoid potential drug interactions.

Underlying health conditions: The safety of long-term tadalafil use depends on an individual's overall health. Tadalafil may not be suitable for individuals with certain medical conditions, such as heart disease, liver or kidney problems, low blood pressure, or a history of strokes.
