Vidalista 10 mg (tadalafil) does not directly increase or decrease libido. Tadalafil helps erections, but it doesn't directly increase sexual desire or testosterone. If you have ED-related anxiety, improved erection confidence may make you feel more interested in sex. A decrease in libido isn't a Vidalista 10 mg tadalafil effect, but it can occur indirectly or because of another condition, medication, stress, or low testosterone. If you have normal desire but difficulty getting or maintaining an erection, tadalafil may help with the erection without changing your underlying level of desire. If you've noticed lower libido specifically after starting Vidalista 10 mg, tell me how long you've been taking it and whether you're taking any other medicines.
