Hello thanks for asking from HCM You have diabetes and hypertension. Both these disorders can cause premature ejaculation so to treat premature ejaculation your blood pressure and diabetes should be under control. Glycomat or Metformin has been reported to cause early ejaculation only in some rare cases and as per my opinion the drug is probably not a cause of your premature ejaculation. Get your BP checked regularly to rule out hypertension as cause of your symptoms. Also get your HbA1c levels checked to find out long term control of sugar. In prematura ejaculation both allopathic and ayurvedic medicines can help. Commonly SSRIs are useful in early ejaculation. Dapoxetine is also a SSRI and the drug is used in SOS basis to delay ejaculation. Herbal medicines like Tantex Royal, Confido are very helpful to delay ejaculation. Apart from this relaxation exercises, Kegel s exercise or pelvic muscle strengthening exercises, Master s and Johnson s start stop technique are very helpful. Please visit a psychiatrist for details of these modalities and prescription of medicines. Thanks, hope this helps you.
