[/INST] Hello,For how long are you taking this medication? And for what purpose you have been prescribed Hydrochlorothiazide? Do you have any edema?If you have been given Hydrochlorothiazide, only for High Blood Pressure (BP), then it is advisable to change the medicine. Because, as you have mentioned, Hydrochlorothiazide drug might increase your sugar levels.If you do not have any of the above symptoms then I suggest you to take Telmisartan drug (twice daily in morning and evening) for a week and check for BP and sugar levels again.If you still have any more doubts do not hesitate to contact us anytime.Hope I have answered your query. Let me know if I can assist you further.Regards,Dr. Indhu Priyadharshini </s>
