How to use Hiprex

Use exactly as directed on the label, or as prescribed by your doctor.

Hiprex works best when your urine has a low pH and is acidic. You can measure your pH levels at home using urine test strips purchased from a pharmacy. Your doctor may occasionally test your urine to make sure an infection has cleared.

Learn about the foods to eat or avoid to help keep your urine acidic. Your doctor may also prescribe other medicines. Drink plenty of liquids.

Follow your doctor's diet and medication instructions very closely.

Keep using this medicine even if your symptoms quickly improve. Skipping doses could make your infection resistant to medication. Hiprex will not treat a viral infection (flu or a common cold).

This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using Hiprex.

Do not use Hiprex to treat any condition that has not been checked by your doctor.

Do not share this medicine with another person, even if they have the same symptoms you have.

Store at room temperature away from moisture, heat, and light. Keep the bottle tightly closed when not in use.

Warnings

Use only as directed. Tell your doctor if you use other medicines or have other medical conditions or allergies.

What other drugs will affect Hiprex

Other drugs may affect Hiprex, especially a sulfa drug. Tell your doctor about all other medicines you use. This includes prescription and over-the-counter medicines, vitamins, and herbal products.
