Hi, my name is Monique. My brother called me tonight to tell me about my father this past weekend. He is 72 years old and always a very active man. He still works (barber). I learned he has been taking something called a quinie for leg cramps. Another possible name Qualaquin? I guess the drug is prescribed here in the USA but it comes from Canada. Over the weekend, my father had difficulty moving around. Said everything hurt, including his back. he would lay on the floor and moan from pain constantly. This is very unusual behavior for my father. I guess he just renewed his prescription (that he has been taking for years) recently which has me concerned if this is a new onset of symptoms. I know he is also on a BP med, however I don t know what kind or dosage. I was told he also drank a lot of water over the weekend too. I m concerned there is more going on here and possible med interactions or something completely different. Leg cramps are a far cry from being in a ton of pain and not being able to move along with the excess intake of water. Can you please advise?
