Fildena CT 50 mg, which contains Sildenafil (the same active ingredient in Viagra), is typically not available over the counter in most countries. It is usually classified as a prescription medication due to the potential risks of misuse, side effects, and interactions with other drugs, especially those used for heart conditions.

Some online pharmacies or unregulated sources may offer it without a prescription, but purchasing from these places can be risky in terms of product authenticity, dosage accuracy, and safety.

To ensure you're using Fildena CT 50 mg safely and effectively, it's best to consult a healthcare provider who can evaluate your health needs and provide a prescription if necessary.
