According to the NHS, medicine such as sildenafil (sold as Viagra) is also often used by doctors to treat erectile dysfunction. It’s also available from pharmacies.
“Because of changes in regulations, you no longer need a prescription to get sildenafil,” explains the NHS.
According to Mr Kanani, a medication known as Tadalafil Daily can be taken every day and is effective in treating erectile dysfunction.
Mr Kanani continued: “Tadalafil has a continuous window of action, so there is no need to schedule doses before sex. This allows for a spontaneous sex life.”
