Nitrofurantoin
"Horrible tablet I have ever taken but cleared it up but on the 3rd day feeling sick from having to dissolve the tablet in a drink and then drinking as I can't seem the swallow it and it dissolves as soon as I put it in my mouth. I wouldn't recommend it as it's the first time ever I've felt so nauseous from taking a UTI tablet as before I was on the capsules and I could swallow them perfectly and didn't feel any nausea."
