Parox CR-37.5 Tablet contains paroxetine, which is mainly used to treat depression, anxiety disorders, and certain sexual problems, such as premature ejaculation. Whether it can help with a problem related to your penis depends on the exact condition you have. For example, if you have premature ejaculation, a doctor may prescribe paroxetine because it can help delay ejaculation and improve control during sexual activity. However, it is not used to increase penis size or treat conditions such as erectile dysfunction, penile infections, pain, swelling, curvature of the penis, or skin disorders affecting the genital area. You should not start taking Parox CR-37.5 Tablet without medical advice, as it may cause side effects and interact with other medicines. It is important to discuss your exact symptoms with a doctor. Once the cause of your problem is identified, the doctor can recommend the most appropriate and safe treatment for your condition.
