Question: My wife is taking Cipro and Metronidazole for diverticulitis (3rd day) and noted pink urination today. She is 69 years old. She has no burning or other urinary discomfort. She is treated for mild hypertension with Lisinopril. She is also a type II diabetic taking glucophage She feels improved on the diverticulitis meds (which she has taken before.) Any suggestions for urgency of followup?
Answered by Dr. Ravi Bansal 4 hours later
Pink or red discolouration in urine can be due to medications like -- Daunorubicin or doxorubicin, heparin, ibuprofen, methyldopa, phenothiazines, phenytoin, phenylbutazone, rifampin, Salicylates, senna. Metronidazole will generally cause brown discoloration of urine.

Medicines causing discolouration is not an issue. the only fear is of blood in urine or infection in urine. this can be confirmed by a routine urine examination test of urine.

Sometimes colour of urine can be due to hemoglobinuria and myoglobinuria. But there are related with anemia (low hemoglobin), high bilirubin in blood.

It may be worth doing the above tests to rule out any other cause.

Hope this helps, in case of any further query feel free to ask.

My husband, age 62, lifelong non-smoker, limited caffeine consumption (1 serving per day), and no ETOH, currently on treatment for HTN, GERD, hypercholesterolemia, and IBS. He had a negative colonoscopy 6 mos ago. A year ago he had a bovine aortic valve replacement and a single secondary CA bypass. Prior to the heart surgery he was very anemic. That resolved with oral iron. Now at his annual physical he has a normal H&H but very low ferritin (15). His mother had a coagulopathy and his sister has IHS. He was tested for IHS but the test was negative. I wonder if there are other tests that could be done (blood tests) re iron stores issues. Our PCP has just said he needs to go back to GI for a repeat colonoscopy. I think that a narrow look at a potentially wider issue. What do you think?

My blood count is just below the normal range, there is the feeling that I am anaemic and I am on iron tablet twice per day. I am also on Aspirin and Lipitor, once per day. Five months ago I had open heart surgery.
