General Information on Hiprex
The generic name of Hiprex is methenamine and it is a urinary antiinfective medicine. Hiprex is prescribed for treatment and prevention of urinary tract infection. Methenamine cannot treat any active infections and hence Hiprex is used only after other antibiotics have been used for treating and curing the bacterial infection. Hiprex has the ability to prevent or stop growth of bacteria in urine. Hiprex basically has an ingredient, which makes urine acidic and Methenamine once administered turns into formaldehyde and kills the bacteria.
Side effects of Hiprex
Hiprex, like most of the medicines in its class, has minor or mild side effects. The most common side effects are upset stomach and nausea. Hiprex can also cause severe side effects in patients with a weak immune system like rashes, hives, redness of skin due to itching, blood in urine, swelling of face and mouth, breathing difficulty, swelling of tongue, and tightness in the chest. If you experience these symptoms, especially blood in your urine, then consult your doctor immediately.
Administration of Hiprex can cause genitourinary side effects like hematuria, dysuria, albuminuria, and increase in urine frequency, bladder wall irritation, gross hematuria, and frequent micturition.
Some of the rare side effects of Hiprex administration include anterior uveitis (ocular), renal insufficiency, and transient elevations of ALT (SGPT) and AST (SGOT).
You must consult your doctor before you buy Hiprex if you are already suffering from serious problems in the liver and kidney. It is not recommended for women in advanced stage of pregnancy and you should consult the doctor before administration. One of the important aspects to understand is that Hiprex is a medicine used for treatment of a specific bacterial infection and should not be used for all bacterial or virus infections.
You can buy Hiprex in the form of white colored, oval shaped tablets, available in packs of 100 tablets with each tablet containing Hiprex 1g. The standard dosage of Hiprex 1g is twice daily in the morning and night for adults and children over 12 years of age. For children between 6-12 years of age, the dosage should be 1/2 to 1 tablet (Hiprex 0.5g to 1g) twice a day. It is an oral medicine and can be taken with or without food. If you miss a dose then take the dose as soon as possible but at the same time ensure that you are not taking 2 doses of Hiprex 1g simultaneously. Store Methenamine tablets in temperatures between 590F and 860F (150C and 300C). It should not be stored in moist places like bathroom and kept away from children.
During administration of Hiprex, it is advised to avoid intake of citrus fruits like lemon and orange as this might lead to interactions. Milk and dairy products as well as antacids should also be avoided during treatment. Apart from interactions, these food products can also decrease the overall effectiveness of the medicine or treatment. Restriction on intake of other alkalinizing medicines should be followed as this can also lead to Hiprex interactions.

What is a "Generic" medication/drug?
Generic drugs are medications that have the comparable medicinal ingredients as the original brand name drug, but which are generally cheaper in price. Nearly 1 in 3 drugs dispensed are "generic". They undergo comparative testing to ensure that they are the same as their "brand" counterparts in:
- Active Ingredient (e.g. "Pravastatin" is the active ingredient in brand name Pravachol)
- Dosage (e.g. 10 mg of the active ingredient)
- Safety (e.g. same or similar side effects, drug interactions)
- Performance (e.g. 10 mg of a "generic" can be substituted for 10 mg of the "brand" and have the same therapeutic result)
- Intended use (e.g. both "generic" and "brand" would be prescribed for the same conditions)
What this means is that "generic" medications can be used as a substitute of their brand equivalents with comparable therapeutic results. There are a few exceptions (examples are outlined at the end of this page) and as always you should consult your physician before switching from a brand name medications to a generic or vice versa.
What differences are there between generic and brand?
While generics and brand equivalent drugs contain comparable active ingredients, they may be different in the following ways:
- Appearance (e.g. the scoring or markings)
The color, shape and size of the medication come from the fillers that are added to the active ingredients to make the drug. These fillers that are added to the drug have no medical use and do not to change the effectiveness of the final product. A generic drug must contain comparable active ingredients and must be comparable in strength and dosage to the original brand name equivalent. Generic drugs can be more cost effective than purchasing the brand name.
Why do generics cost less than the brand name equivalents?
When a new drug is "invented", the company that discovered it has a patent on it that gives them the exclusive production rights for this medication. Once the patent expires in a country, other companies can bring the product to market under their own name. This patent prevents other companies from copying the drug during that time so they can earn back their Research and Development costs through being the exclusive supplier of the product. After the patent expires however, other companies can develop a "generic" version of the product. These versions generally are offered at much lower prices because the companies do not have the same development costs as the original company who developed the medication.
The main thing to realize here though is that the two products are therapeutically comparable. They may look different, and be called something different, but they are required to be have the same active ingredient.
How are Generic drugs tested to ensure quality and efficacy?
The two most generally accepted methods to prove the safety of a generic version of a drug are to either repeat most of the chemistry, animal and human studies originally done, or to show that the drug performs comparably with the original brand name drug. This second option is called a "comparative bioavailability" study. During this type of study, volunteers are given the original drug, and then separately later the generic drug. The rates at which the drug is delivered to the patient (into their blood stream or otherwise absorbed) are measured to ensure they are the same. Because the same active ingredient is used the major concern is just that it delivers the common chemical(s) at the same rate so that they have the same effect. Please note that the methods that the manufacturers use may vary from country to country.
