The primary purpose of Azo tablets is to help release urinary leakage and urgency. However, there have been complaints about this tablet that it is causing weight gain. The officials of AZO have tried to clarify this issue in one of their responses to Amazon customer questions.

According to them, Bladder Control with Go-Less from AZO does not cause sudden weight gain. The Go-Less ingredient blend is not known to have any major side effects. Still, it is best to consult your doctor before taking any dietary supplement.

If we take a deep look at their response, they have suggested consulting the physician before taking their supplement. Why is it so?

Phenazopyridine is a vital component of AZO tablets. It helps to relieve symptoms of UTI (Urinary Tract Infection). People suffer from various problems like pain, burning feelings, irritation, increased urge for urine, and even frequent urination.


Also, this medicine is prescribed for the treatment of urinary symptoms caused by surgery, injury, or medical procedures.

Phenazopyridine has certain side effects. Some of the common side effects are –

  • Headache;
  • Dizziness
  • Stomach Upset

Apart from those common side effects, some occasional side effects are also reported. Such as-

  • Blue or blue-purple color of skin
  • Fever and confusion
  • Wheezing, shortness of breath, or trouble breathing
  • Skin rash
  • A sudden decrease in the amount of urine
  • Swelling of face, fingers, feet, and/or lower legs
  • Unusual tiredness or weakness
  • A sudden increase in weight
  • Yellow eyes or skin

So, we can see weight increase is a rare side effect of phenazopyridine, but that does not happen very often. Not every human body responds equally to health supplements. However, most of the users never face any of those mentioned side effects above.

If you are one of the AZO users and have noticed any of these side effects after taking the supplement, seek medical attention immediately.
