Why Azo Didn’t Turn My Pee Orange? What’s the Reason

Why Azo Didn’t Turn My Pee Orange

Many people take Azo, a medication commonly used to ease urinary tract symptoms and expect to see a change in their urine color to orange. This changing color is one of Azo’s most well-known effects.

However, not everyone experiences this, so you might be curious why your urine didn’t turn orange post-consumption. It’s a phenomenon that might leave you puzzled, but there are many reasons why this could happen.

From the dosage you took, to how your body metabolizes the medication and even the amount of water you drink, many factors can influence how Azo affects your body.

In this article, we’ll explore some of these reasons and explain why Azo may not have turned your pee orange.

Knowing About What is Azo?

Azo is the brand name for a group of over-the-counter drugs that are used for alleviating symptoms linked with urinary tract infections (UTIs), like urgency, pain, and the sensation of needing to urinate frequently.

The active ingredient in most Azo products is Phenazopyridine, which works as a pain reliever that affects the lower part of the urinary tract, offering temporary relief.

It’s not an antibiotic and doesn’t cure the cause of the urinary irritation but can make the discomfort more bearable while waiting for antibiotics to take effect or for minor urinary symptoms to resolve on their own.

How does AZO work?

Doctors are not sure how AZO actually works which is a dye that builds up in the bladder. But what they do know is that this medication puts a stop to the intense urge to urinate and or stops that pain when you go.

Experts said that Phenazopyridine, the active ingredient in Azo, works by being excreted in the urine and targeting the lining of the urinary tract. It acts as a pain reliever for the inside of the bladder, easing discomfort, urgency, and the need to pee often.

This helps ease pain, burning, and irritation from UTIs, surgery, or other urinary issues. It’s often used with antibiotics for UTIs.

The reason Phenazopyridine can alter urine color to an orange or reddish color is due to the dye that is excreted along with the medication. This change in urine color is usually harmless and should resolve after discontinuation of the medication.

How long does AZO take to work?

Usually, Azo begins to take effect within 24 hours after ingestion, with many individuals noting a significant reduction in discomfort and urgency in urination.

Many people also report that the pain relief is noticeable within an hour of taking the medication. Which makes it a popular choice for those experiencing UTI symptoms. However, the medication may take longer to work if you have kidney or liver problems.

Since AZO works quickly, it should only be used for short-term relief while waiting for antibiotics to take effect or for minor urinary symptoms to resolve on their own.

It is not recommended as a long-term solution and should not be taken for more than two days unless directed by a doctor.

Can AZO turn your urine orange?

Can AZO turn your urine orange

Yes, Azo can turn your urine an orange or reddish color. This happens because of Phenazopyridine, which is in Azo. It’s like a dye that comes out in your pee.

This color change in your pee is normal when taking the medication. It shows your body is processing the medicine.

The color change in pee is usually harmless, but it can stain your clothes permanently. So, be careful and use panty liners when using it. Remember to wash your hands before touching contact lenses too, as the dye can stain them.

Why Azo Didn’t Turn My Pee Orange?

If you are not experiencing a change in urine color after taking Azo, don’t panic. There are many reasons why this could happen.

Each person’s body works differently, affecting how things are processed and removed. This can lead to different side effects, such as urine turning orange, which vary among individuals.

Possible Reasons

Below are some of the possible reasons why Azo did not affect your urine color:

You didn’t take the recommended dosage: Azo comes in different forms and dosages, and not all of them contain enough Phenazopyridine to cause a visible change in urine color. Make sure you are taking the correct dosage as directed by your doctor or listed on the package.

Your urine was already diluted: This may be the main reason in your case that you were already drinking a lot of water. Your urine may have been sufficiently diluted to not show any color change. It’s important to stay hydrated, especially when experiencing UTI symptoms, but it can also make it harder for Azo to turn your pee orange.

Your body metabolizes differently: As mentioned earlier, everyone’s body works differently, which can affect the way Azo is metabolized and excreted. Some people may have a faster metabolism, leading to quicker excretion of the medication and less time for it to build up in the bladder.

The color change is not noticeable: In some cases, the change in urine color may be subtle or may only affect certain individuals. For example, people with dark-colored urine may not see a significant difference when it turns orange.

If your pee color doesn’t change after using Azo, it doesn’t always mean the medicine isn’t working. It could just be because everyone’s body reacts differently to it or other things influencing the response.

Recommendations for Monitoring

When checking how your body reacts to Azo, especially with changes in urine color, it’s important to take a methodical approach to make sure you see and handle any possible side effects correctly. Here are some tips that can help you:

1. Maintain a Hydration Log: Keep track of your fluid intake to understand how hydration affects the concentration and color of your urine. This can help you differentiate between changes caused by Azo and those due to your hydration levels.

2. Note the Amount and Time: Write down how much Azo you take and when. This info is important for you and your doctor to see how your body reacts to the medicine.

3. Observe Urine Color Regularly: Regularly check the color of your urine to monitor any changes. It’s helpful to do this under similar lighting conditions to avoid misinterpretation caused by different light settings.

4. Note Other Symptoms: Besides checking the urine color, pay attention to any other symptoms you might experience, like pain relief or urgency. This can give you a better view of how well Azo is working for you.

5. Consult Healthcare Provider: If you notice any unusual side effects or if your symptoms persist despite taking Azo, consult with your provider for further evaluation and guidance.

When to seek a doctor

While Azo is generally safe to use, there are some instances when you should seek medical advice. These include:

  • If your UTI symptoms do not improve or worsen after 2 days of using Azo.
  • If you experience severe side effects like difficulty breathing, swelling, or hives.
  • If the orange or reddish color in your urine continues for more than a few days after stopping Azo.
  • If you have a history of kidney or liver problems, consult before starting Azo.
  • Consult your healthcare provider before using Azo if you are pregnant or breastfeeding.
  • If you know you are allergic to Phenazopyridine or any other components of Azo.

Remember, Azo is for short-term help only. Don’t use it instead of antibiotics or for a long time. Take the right amount and talk to your doctor if you have questions about using Azo.


Azo gives fast and effective short-term relief for urinary tract symptoms, a great choice for quick comfort. But remember, to use it carefully by following the dosage instructions and duration guidelines. The color of your pee changing doesn’t mean the medicine is working well so it’s good to keep your expectations realistic.

Remember, Azo is not a replacement for a doctor’s advice or treatment. Talk to healthcare providers if symptoms continue or before taking a new medicine, especially if you have existing health issues.


How long after taking Azo can I take a urine test?

It’s recommended to wait at least 48 hours after your last dose of Azo before taking a urine test. This is because Azo can impact the accuracy of urine tests, including urine analysis and urine culture, by coloring the urine and potentially masking the presence of bacteria or other substances being tested for.

Why is Azo not working after 2 hours?

There could be a few reasons why Azo is not working within 2 hours. It could be due to factors like UTI severity, how fast your body metabolizes it, or if you took it on an empty stomach. Usually, Azo starts easing pain and urgency a few hours post-intake, but in some instances, it could take longer. But if your symptoms persist after 2 days, it’s recommended to consult with your healthcare provider for further evaluation and treatment.

Is my pee supposed to be yellow after taking AZO?

After taking AZO, it is common for your urine to turn a brighter orange or even a reddish color rather than yellow. This color change is due to the active ingredient Phenazopyridine. The intensity of the color can depend on your hydration levels and how your body metabolizes the medication. Therefore, seeing an orange or reddish hue instead of the usual yellow is expected and indicates the medication is being processed by your body.
