Vidalista Professional Both are marketed for erectile dysfunction, but there is insufficient reliable evidence to say that Professional is more effective or faster than Soft. For reliability: Ask your doctor about an approved, standard tadalafil tablet with established dosing and clinical evidence. For safety: Check the exact product, strength and instructions with your pharmacist. Both may carry tadalafil's risks, including headache, flushing and low blood pressure. Never combine them with each other or with other erection medicines without medical advice. Do not take tadalafil with nitrate medicines or riociguat. One important question: Are you comparing Vidalista Professional 20 mg with Vidalista CT Soft 20 mg, or with Vidalista Soft 10 mg? The strength matters when comparing safety and dosing.
