Tadasoft 20 mg, as with any medication. Tadasoft contains Tadalafil, which is a phosphodiesterase type 5 (PDE5) inhibitor, and while it is generally well-tolerated, side effects can still occur. Not everyone will experience these side effects, and they tend to be mild or temporary. However, some individuals may experience more noticeable or persistent issues. Common Side Effects The most common side effects of Tadasoft 20 mg are typically mild and include: Headaches Flushing (reddening of the skin, especially on the face) Indigestion (dyspepsia or upset stomach) Nasal congestion (stuffy nose) Back pain or muscle aches (usually appearing 12-24 hours after taking the medication) Dizziness or lightheadedness Vision changes (e.g., seeing a blue tinge to objects or difficulty distinguishing between blue and green) These side effects usually go away after a few hours or days as your body adjusts to the medication. They are relatively mild and not necessarily cause for concern unless they persist or worsen. Less Common but Serious Side Effects Although rare, some more serious side effects can occur: Prolonged erection (priapism): An erection that lasts more than 4 hours. Tadasoft 20 mg is a medical emergency and requires immediate attention to prevent permanent damage. Sudden vision loss: This is extremely rare but can indicate a serious condition (non-arteritic anterior ischemic optic neuropathy or NAION). Hearing loss or ringing in the ears: This is another rare but serious side effect that should be reported to a doctor. Chest pain, dizziness, or shortness of breath: If you experience any of these symptoms, it could be a sign of a heart-related issue, and you should seek immediate medical attention. Risk Factors Certain factors can increase the likelihood of experiencing side effects: Existing health conditions: People with certain conditions like heart problems, kidney or liver disease, high or low blood pressure, or eye conditions may be at higher risk for side effects. Interactions with other medications: Tadasoft 20 mg may interact with other medications, especially nitrates (used for heart conditions) or alpha-blockers (used for prostate issues), leading to dangerous drops in blood pressure. Alcohol consumption: Drinking alcohol while taking Tadasoft may increase the risk of side effects, such as dizziness or headaches.
