Dapoxetine sometimes used for premature ejaculation. However, it is not a first-line solution for everyone, especially at your age (21 years). The correct dose, safety, and duration depend on your overall health, other medications, and whether premature ejaculation is persistent and distressing.
Usually, non-pharmacological methods (behavioral techniques, reducing anxiety, pelvic floor exercises, avoiding excessive masturbation/porn, and lifestyle modification) are tried first. Medications are considered only if these measures fail, and even then, it must be started under direct supervision of a qualified psychiatrist/urologist
Next Steps
Please consult a psychiatrist or urologist in person. They will assess if medication is needed, and if yes, prescribe the correct dose and duration safely.
Health Tips
Important: Do not self-prescribe dapoxetine or use an online sample prescription. Taking it without evaluation can lead to side effects (like nausea, dizziness, low blood pressure, or mood changes) and may not address the root cause.
