My husband is on betahistine and Lasix for his meniers didn't find that it did to much but again maybe it did. With the side effects of the different medications one never knew what was real or side affect. He wasn't able to function "normally" for awhile he went days in bed in fetal position not being able to keep anything down as he was so dizzy. At times when I took him to emerg as he got dehydrated he felt a bit better with iv fluids but it seemed like it just had to wait for it to pass....... so frusterating as mentally u just feel helpless not being able to do normal daily activities (even getting out of bed and get dressed ) just started a return to work after not being able to work for 2 yrs. Hang in there you got this!!
