Paroxetine for premature ejaculation medication time is not certain, the patient’s cause of the disease, the condition of different treatment time is also different. It may be cured with 2~3 times of medication, or it may have no effect. Strictly speaking, paroxetine is not a drug for treating premature ejaculation, and the instruction manual clearly states that it is for treating depression, obsessive-compulsive disorder, social anxiety disorder and other mental illnesses. Because paroxetine has the side effect of inhibiting ejaculation, its inhibition of ejaculation has also been utilized clinically to treat premature ejaculation. For premature ejaculation caused by psychological factors, some patients may achieve good results after 2-3 times of medication, while some patients may have no effect. If there is a reproductive system infection causing premature ejaculation, without controlling the infection, it is also difficult to cure with paroxetine alone. Overall, patients with premature ejaculation need to go to the hospital in time for examination and targeted treatment after clarifying the cause, and it is not recommended to blindly take paroxetine.
