The effect time of taking Three Kidney Pills is not fixed, it needs to be analyzed on a case-by-case basis and cannot be generalized. It is mainly used for the treatment of cold pain in the waist and knees, impotence, premature ejaculation and sexual dysfunction caused by the deficiency of kidney essence and yuan yang. Due to the different conditions and physical qualities of patients, as well as the differences in the ingredients of different brands or types of Three Kidney Pills, there are differences in the time of taking the medicine and the dosage. Patients with mild symptoms may take 2-4 weeks (a course of treatment) to produce certain effects, while those with severe conditions may need two consecutive courses of treatment. Therefore, it is recommended that patients go to the TCM department to understand their condition first and use the medication under the guidance of the doctor. In addition, patients should avoid eating cold, spicy and greasy food during the medication period. Because this medicine treats sexual dysfunction, intercourse is not allowed during the medication period, so as not to affect the efficacy of the medicine and not to achieve the desired effect.
