My husband has had a burning sensation after urinating, some nights ago. And it felt like after he had urinated, there was still some urine left, if it makes any sense. He was also sweating. Now all of that is gone but he is having lower back pain. We haven't been able to go to the doctor yet but I have a pack of Monurol 3g (fosfomycin), which is usually used for women's UTIs according to the label.
Should he take the Monurol until we are able to go to the doctor, or is it better not to? I have my reserves as I'd rather he is tested for UTI and other possible issues first.
I would say no to that as you should never give other people your medication, go to the doc asap, in the meantime get your husband to drink loads of water and if the back pain gets any worse go to A&E.
As the guidance for Monurol 3g says to only use it for bladder infections, it might not be good for him to take it, as it is not suitable for kidney infections (and presumably not for infections in the prostate). Also, a culture from his urine sample is needed to identify which bacterium he has - some antibiotics are ineffective, due to bacterial resistance.
UTIs in men are usually more serious than in women so watch him carefully for signs of temperature, mental confusion or worsening back pain. Like the other two replies say, go to A&E if things get worse but make sure you at least get a urine sample in and seen by a doctor ASAP.
Please let me advise you against being given an antibiotic called Ciprofloxacin (or any others in the same class called the fluoroquinolones). This is often given to UTI patients as it is broad spectrum and will kill most bugs. It's unfortunately very strong and can lead to many serious problems which your husband certainly doesn't want - please see the discussions on this site about it to get an idea of what I mean.
I wish him well and hope that he gets sorted out very soon.
