It’s best to avoid or limit alcohol when taking Vidalista 60 mg (tadalafil). Alcohol can increase tadalafil-related effects such as dizziness, headache, flushing, and low blood pressure, and larger amounts of alcohol may make it harder to achieve or maintain an erection. Also, 60 mg is higher than the usual maximum recommended on-demand tadalafil dose of 20 mg, so it should not be taken unless specifically prescribed by a healthcare professional.
