Although the most well-known prescription medication for erectile dysfunction may be Vidalista 40 mg, there are other options as well. Do not take more than one pill of the prescribed medication within 24 hours of the previous dose to avoid overdose symptoms. With a glass of water, the pills can be taken orally 30 to 60 minutes before having any sexual activity. But make sure you swallow it completely. Never break or chew the prescription pill. Take a complete Vidalista 40 mg and drink some water. If the tablet is broken, chewed, or crushed before use, its effectiveness will be reduced. PDE5 inhibitors and generic Vidalista 40 mg share the same pharmacological class.
