Why does my body feel so cold after taking my last dose of nitrofurantoin? Kind of like fever but do not actually feel sick. Side effect?

Why does my body feel so cold after taking my last dose of nitrofurantoin? Kind of like fever but do not actually feel sick. Side effect?

?: Some people have just fever from a drug and the condition is called drug fever. The mechanism is unknown. You may also have chills (sensation of being cold) before the fever comes on. Given that you only had this sensation after having taken the last dose, the diagnosis is uncertain but it would still be wise to avoid this drug in the future since there are other options. ...Read more

Phenazopyridine (Pyridium®) or the equivalent over-the-counter product (Azo® and others) can help control symptoms in the days before the antibiotic kicks in.

I9 weeks preg with a UTI. Prescribed 3 tablets a day of Nitrofurantoin [30 tablets] but instructions say 4 tabs over 7 days? What is the correct dose?

Double check with MD: I would call the office to clarify - usually nitrofurantoin is given 4x a day, but maybe there was some reason they wanted only 3x a day. That might be if you have any pre-existing kidney trouble, in that case - a slightly lower amount might be better for you. This medicine is considered 'safe' in pregnancy - for the stage of pregnancy you are in now. Good to get the infection over and done with. ...Read more
