furosemide can be giving every how many hours
Expert: Dr.Fiona replied 7 years ago. So, let's start with the lasix (furosemide). As I mentioned, there is a wide dose range that is used with this drug. The high end of the dose suggested is 4.4 mg/kg given as often as every 8 hours. This would work out to 16mg every 8 hours for your dog-or 48 mg per day.
