Orange urine is usually caused by something you ate, drank, or took as a supplement or medication. In most cases, it resolves on its own within a day or two. Less commonly, it can signal dehydration or, rarely, a problem with your liver or bile ducts.
Medications That Turn Urine Orange
The most common reason for bright orange urine is medication. Phenazopyridine, a bladder pain reliever often prescribed alongside antibiotics for urinary tract infections, is one of the most well-known culprits. It reliably turns urine a vivid reddish-orange, and the change can be startling if you’re not expecting it. The effect lasts as long as you’re taking the drug and clears within a day or so after you stop.
Other medications that can shift urine toward orange include sulfasalazine (used for inflammatory bowel conditions and rheumatoid arthritis), certain laxatives, and some chemotherapy drugs. If you recently started a new medication and noticed the color change, that’s very likely the explanation. The drug’s breakdown products are simply being filtered through your kidneys and exiting in your urine.
Vitamins and Supplements
B vitamins are notorious for changing urine color. Vitamin B-12 can turn urine orange or yellow-orange, and vitamin C supplements can do the same. High-dose vitamin A also produces an orange tint. If you’ve recently started a new multivitamin or B-complex supplement, that’s a probable cause.
Your body excretes the excess of water-soluble vitamins (like B and C) through urine relatively quickly. Most people notice the color returns to normal within a day or two of stopping the supplement, or even just by the next morning if they took a single dose.
Foods High in Beta-Carotene
Eating large amounts of beta-carotene-rich foods can give urine a light orange hue. Carrots are the classic example, but sweet potatoes are actually the biggest source, packing over 23,000 micrograms of beta-carotene per cooked cup. Butternut squash, cantaloupe, and red peppers are also high on the list.
When you eat a lot of these foods regularly, the pigment can also build up in your skin, a harmless condition called carotenemia that gives skin a yellow-orange tint (most noticeable on the palms and soles). It’s not dangerous. Cutting back on those foods and diversifying your fruit and vegetable intake brings everything back to normal.
Dehydration
Sometimes what looks orange is really just very concentrated yellow urine. When you’re not drinking enough fluid, your kidneys produce less urine and it becomes more concentrated with waste products, deepening the color from pale yellow toward amber or dark gold. In moderate to severe dehydration, this can tip into an orange-looking shade, often accompanied by a stronger smell and smaller volume.
A simple test: drink two or three glasses of water over the next hour or two. If your urine lightens noticeably, dehydration was the issue. Pale straw to light yellow is the color range that indicates good hydration.
Liver and Bile Duct Problems
This is the cause worth being aware of, even though it’s far less common than the others. When the liver isn’t processing bile properly, or when a bile duct is blocked (by a gallstone, for example), a pigment called bilirubin can build up in the blood and spill into the urine. This produces a dark orange, brownish-orange, or tea-colored urine.
The key difference is that liver-related orange urine almost never shows up in isolation. You’d typically also notice one or more of these signs:
- Yellowing of the skin or whites of the eyes (jaundice)
- Pale or clay-colored stools, because the bile pigment isn’t reaching the intestines
- Itchy skin, from bile salts accumulating
- Pain in the upper right abdomen
- Fatigue or nausea
If you’re seeing orange urine alongside any of those symptoms, that combination warrants a medical evaluation. A simple urine test and blood panel can check bilirubin levels and liver function to confirm or rule out the issue quickly.
How to Figure Out Your Cause
Start with the most likely explanations first. Think through what you’ve taken or eaten in the past 24 to 48 hours. A new medication, a handful of supplements, or a big serving of sweet potato soup will explain most cases.
If none of those apply, try increasing your water intake for a day. Most non-medical causes of orange urine clear up within one to two days. If the color persists beyond that, if it’s accompanied by pain, or if you notice any signs of jaundice, a basic urinalysis can identify whether bilirubin, blood, or other abnormal substances are present. That simple test gives a clear picture of whether something more is going on or whether your body is just processing a harmless pigment.
