Posted over a year ago

I have been taking the generic for Kelfex for 5 days and i only have one side effect so fan and it is a splitting and pounding headache when I am stimulated sexually -physically...I have to stop immediately because the headache seems to last forever!!! I am not prone to headaches...in fact I can count on one hand how many I have gotten in my life and i have gotten three in 5 days.
