<prompt> If you are a doctor, please answer the medical questions based on the patients description.Dear Doctor, i gave a 40 yr old man with mild hypertension 12090mmhg, Telvas -Htelmasartan hydrochlorthiazide. However 6 months on the drug he complained of erectile dysfunction which is progressively worsening. Hes blood pressure is still high at 11090mmhg. Should i change the drug? What should i do for him.  <response>: HellloThanks for query. At the outset I would state that the problem of ED that your patient has can not be due to mild hypertension that he has, He needs to be investigated on following lines to rule out any organic cause for his ED, 1 Blood sugar levels to rule out Diabetes 2 Thyroid Hormone assessment .3 Color Doppler Ultrasound Scan of penis. If there is no organic cause for his Ed it can be considered to be Psychogenic in origin and guide him to Psychiatrist for counselling. You can try and prescribe him Sildenafil Viagra. This may resolve his problem of ED. Chat Doctor.
