Hello XXXXXXXXXX,
Welcome to JustAnswer.
Is he acting normally otherwise? In other words, does he have any other symptoms besides back ache and dark urine? Fever? Confusion? Not eating or drinking?
Hello,
His urine is probably dark because he is not drinking. He must start drinking some water, otherwise he will end up in the hospital with dehydration. The other thing could be the bladder infection has not cleared up, or his kidneys are also involved.
For tonight, try to get him to drink any kind of clear liquids. Hot, cold, whatever he likes. Maybe some herbal teas with sugar. He really needs to get the fluids in. The antibiotic could have caused him to be nauseous to begin with, but now he may be still feeling nausea because of dehydration.
He should see his doctor tomorrow, definitely. But for this evening and tonight try to get him to understand that he just has to drink some water.
