OK, with my doctor's hat on . . .
It all depends how old she is. Children do tend to grow out of bedwetting by the age of about nine . . . but it's a long time to wait and a lot of sheet-washing to do meantime.
The most important thing is not to make her feel guilty about it, because this will cause tension which will make the problem worse.
You mention medication, which suggests that you've consulted your doctor about it. If he hasn't doesn't so, ask him to test her urine. There's unlikely to be any problem there but, just occasionally, bedwetting can be associated with a urinary tract infection.
As to non-drug treatments, there are several which work well. The first is a 'buzzer' which your doctor ought to be able to get for you (or tell you where you can get it). You put it in the bed and, as soon as it gets even slightly damp, it goes off and wakes the child up. Over a period of time, the child gets so used to waking up just as she is starting to wet the bed that, eventually, she will wake up just before . . . and in time to get to the loo.
The next treatment (which is my favourite) is hypnotherapy. However, this doesn't really work until the child is about 8 or 9 . . . old enough to co-operate. But it does work a treat for kids who are suitable. You would need to see a medical hypnotherapist and, here again, your doctor should be able to advise you.
A third option is homoeopathy. You would need to see a therapist . . . it's not a situation where you can self treat . . . and it might take a while to clear up, but it's a very safe and gentle method of treatment. And it's suitable for children of any age.
And finally, there's acupuncture. However, this isn't always suitable for children because of the 'needle' aspect. However, for kids who don't mind needles, it can work extremely well. Like homoeopathy, there's no minimum age limit. And like homoeopathy, you need to see a properly qualified therapist . . . not just a doctor who uses the therapy (and probably hasn't done a full training).
