Military Viet Nam vet feel great. Problem too low, no no meds take metformin 1000 mg dailyzocor20 mg daily aspirin 81 mg problem no too low  <response>: Hello, Thanks for the query. I have gone through the details given. Your BP reading of 9874 mm Hg, shows a slightly lower systolic BP. But it can not be balled as as low BP. It is at the lower end of the normal BP range. Metformin 1000 mg or higher has no effect on BP. Its major side effects are related to gastrointestinal disturbances, that too when taken on empty stomach. You should consume more of liquids and plenty of water. Unless you have any specific symptoms due to so-called low systolic BP, there is no reason to worry. Thanks
