Hiprex is a urinary antibiotic tablet made up of methenamine hippurate. We carry both the brand choice and generic alternative in 1g.

Hiprex is used to prevent bladder infections in people who are prone to them (get them often). Typically Hiprex is given after other antibiotics have treated the initial infection because Hiprex will only help kill the bacteria (cause of the infection) but won’t chemically help the infection to heal. Bladder infections are usually painful and can be caused from bacteria by frequent sexual intercourse, sexual intercourse with a new partner, diabetes, or having a recent bladder or kidney infection.

This medication is effective in the treatment of bladder infections due to its contents containing an ingredient that allows the urine to become more acidic, allowing a chemical change (methenamine turns into formaldehyde), killing the bacteria in the urine.

Re-read all the directions on your prescription label before proceeding to take Hiprex; follow your doctor’s instructions very carefully. Taking more of a dose than prescribed will not help heal your condition faster but could worsen the unwanted side effects.

This medication is taken by mouth, regularly (daily).

If giving this medication to a child, you may have to break the tablet in half; consult your doctor if you are unsure how much to give your child.

Drink plenty of water during the duration of treatment. Your doctor may suggest drinking drinks such as cranberry juice, to help make your urine more acidic.  They may ask you to avoid dairy products.

If you symptoms improve quickly, do not stop taking the medication. Continue taking the medication for the entire prescribed time/amount.

Store at room temperature away from moisture, heat and light. Keep the bottle tightly closed when you are not using it.

Certain diseases and conditions may interact with Hiprex or cause a contradiction.

Speak with your doctor if you have or had liver disease, asthma, an allergy to aspirin, or an allergy to yellow food dye.
