Fildena is available in multiple strengths and formulations (such as standard tablets, chewable, or fast-acting versions), allowing doctors to choose a dose based on individual needs. It is usually taken about 30 to 60 minutes before sexual activity, and its effects typically last for several hours. Common side effects may include headache, flushing, dizziness, nasal congestion, indigestion, and mild visual disturbances such as blurred vision or light sensitivity.
