How long does AZO stay in your system?

The amount of time AZO (phenazopyridine) stays in your system depends on several factors, including:

  • Dosage: Higher doses will take longer to be eliminated from your body.
  • Metabolism: Individuals with faster metabolisms will clear AZO from their system more quickly.
  • Kidney function: Healthy kidneys will eliminate AZO more efficiently than those with impaired function.
  • Hydration: Drinking plenty of fluids helps to flush out AZO from your system.

Here is a general breakdown of how long AZO stays in your system:

  • Peak concentration in blood: Within 1-2 hours after taking a dose.
  • Detectable in urine: Up to 24 hours after the last dose.
  • Completely eliminated from the body: May take 48-72 hours or longer.

However, it’s important to note that these are just estimates, and the actual time may vary for each individual.

Here are some additional things to keep in mind:

  • Urine color: AZO can dye your urine orange or red. This is harmless and will resolve once you stop taking the medication.
  • Contact lenses: AZO can also stain contact lenses. It’s recommended to avoid wearing contact lenses while taking AZO.
  • Other medications: AZO can interact with other medications, so it’s important to talk to your doctor or pharmacist before taking it.

If you have any concerns about how long AZO will stay in your system, it’s best to talk to your doctor. They can provide you with personalized advice based on your individual circumstances.

How long does AZO Maximum Strength take to work?

AZO Maximum Strength can start working within 20 minutes to 1 hour after taking a dose. Some people may experience relief even sooner, while it may take a bit longer for others to feel the full effects.

It’s important to note that AZO doesn’t cure a UTI, but it can provide temporary relief from symptoms like burning, urgency, and pain when urinating. It works by numbing the lining of the urinary tract, which can help to reduce discomfort.

What happens if you take too many AZO pills?

Taking too many AZO pills can lead to overdose, which can be serious and require immediate medical attention. Symptoms of AZO overdose may include:

  • Unusual tiredness
  • Skin color changes (e.g., yellowing of the skin or eyes)
  • Change in the amount of urine you produce
  • Shortness of breath
  • Fast heartbeat
  • Seizures
  • Nausea and vomiting
  • Diarrhea
  • Headache
  • Dizziness

In severe cases, AZO overdose can lead to liver damage, kidney failure, and even death.

Here’s what you should do if you suspect an AZO overdose:

  • Call 911 or your local emergency number immediately.
  • Do not wait for symptoms to appear.
  • If possible, take the AZO bottle or packaging with you to the hospital.
  • Tell the healthcare provider how many AZO pills you took and when you took them.

It’s also important to follow the recommended dosage instructions on the AZO label. Never take more than the recommended dose, and don’t take AZO for longer than 2 days without talking to your doctor.

Here are some additional resources that can help:

  • The Poison Control Center: 1-800-222-1222
  • Your doctor or healthcare provider

It’s important to remember that self-treating a UTI is not recommended. If you suspect you have a UTI, see your doctor for proper diagnosis and treatment.
