Frequently Asked Questions about Hiprex


What is Hiprex used for?

Hiprex is a urinary antiseptic used to help prevent recurrent urinary tract infections. It is not used to treat active infections but helps reduce the risk of new infections from developing.


How does Hiprex work?

Hiprex works by breaking down into formaldehyde in acidic urine. Formaldehyde acts as an antiseptic that suppresses the growth of bacteria in the urinary tract.


How is Hiprex typically taken?

Hiprex is taken by mouth, usually twice daily, with or without food. It is often taken long term as part of an infection prevention plan.


Does Hiprex treat an active urinary tract infection?

Hiprex does not treat active urinary tract infections. It is intended only for prevention after an infection has been treated with appropriate antibiotics.


Why is urine acidity important when taking Hiprex?

Hiprex requires acidic urine to work effectively. In some cases, additional measures may be used to help maintain urine acidity so the medication can properly release its antiseptic effect.


What are the most common side effects of Hiprex?

Common side effects include nausea, upset stomach, painful urination, or mild bladder irritation. These effects are usually mild and temporary.


Can Hiprex cause serious side effects?

Serious side effects are uncommon but may include severe bladder irritation or allergic reactions. Persistent pain, rash, or unusual symptoms should be evaluated.


Can Hiprex be taken long term?

Are there medications or supplements that interact with Hiprex?

Certain medications that make urine less acidic may reduce Hiprex effectiveness. All prescription medications, over-the-counter products, and supplements should be reviewed before use.


Is Hiprex safe during pregnancy or breastfeeding?

Use during pregnancy or breastfeeding should be carefully considered. While it has been used in these situations, treatment decisions are based on weighing potential benefits and risks.
