Does levitra (vardenafil) 10mg orodispersible could be cut in half as the usual tablet and does it less effecting stomach problems ?

Possibly: Side effects with any medication will be reduced when you reduce dosage. But reduced side effects can still be significant.

Yes and no: Levitra (vardenafil) can be cut in 1/2 but you may wanna get the 20 mg and cut those. I do not think they cause stomachroblems but go to the website and see. I often prescribe a higher dose of medsand have people break them; it generally helps save tons of money; good luck and try some ranitidine, it may just be reflux.
