Sildenafil citrate tablets and tadalafil tablets belong to the same class of phosphodiesterase type 5 inhibitors and are indicated for the treatment of erectile dysfunction in men over 18 years of age. However, there is no authoritative study on the comparison of the side effects of these two drugs, and the occurrence of side effects and their severity will be affected by the physical condition of the user and compliance, other therapeutic measures, and other factors, the specific performance of individual differences can exist. Therefore, it is not possible to give a precise answer as to which side effect is less, Sildenafil Citrate Tablets or Tadalafil Tablets.
