Your doctor may be right. But at the same time, I'd like to play it safe. Lisinopril (an ACE inhibitor) is a medication that has the potential to affect both your liver and kidneys. And dark urine may be indicative of effects on both or one of those organs.

I don't want to scare you or anything, but if you're blood pressure is on the high side, medication will definitely help. There may be other blood pressure controlling medication that may suit you better, such as a diuretic. But many factors come into play in determining which medication is best suited for you.

By the way, how long have you been on Lisinopril? And what exactly is your currently Blood pressure reading if I may ask? When you say "dark" what exactly do you mean? Dark Yellow? Or Dark Red/black?

If dark yellow, then increasing your fluid intake is way to go. But if dark red/black, increasing fluid intake will only "mask" the signs of possibly (again, not saying definite, but is a possibility) LIVER or KIDNEY involvement.

And when I say "mask," I mean dilute the "darkness of the urine," thereby disregarding possible liver/kidney involvment. I suggest you meet with your doctor and run some Kidney (serum creatinine (Scr), blood urea nitrogen (BUN) and some Liver function test (AST, ALT, etc). But again, I don't want to scare you, so you instead of going out and getting laboratory test (obvious money comes into play), speak with your doctor about your medication possibly interacting with your liver or kidney, ok??
