Dapoxetine, generally referred to as dapoxetine hydrochloride, may cause side effects such as nausea, vomiting, diarrhea, and dizziness. They are usually not particularly serious and may resolve on their own after the drug is discontinued. Dapoxetine Hydrochloride is the name of a Western medicine, commonly available in tablet form, and is used clinically to treat male patients between the ages of 18 and 64 years old who have significant personal distress or interpersonal difficulties caused by persistent or recurrent ejaculation due to minimal sexual stimulation of the penis prior to sexual gratification, poor control of ejaculation, or premature ejaculation. Adverse reactions such as mild headache, nausea, vomiting, diarrhea, vertigo, and fatigue may occur after taking dapoxetine hydrochloride. It is contraindicated for people who are allergic to any of the ingredients, have significant pathological conditions of the heart, and severe liver damage. This product should not be used in people under 18 years of age. Dapoxetine Hydrochloride is a prescription drug, which should be applied reasonably under the guidance of a professional doctor, avoiding blind use of the drug, so as not to cause discomfort to the body.
