Mandelamine

(Methenamine Mandelate)

The active ingredient in Mandelamine is methenamine mandelate.

Methenamine mandelate breaks down in acidic urine to release formaldehyde. Formaldehyde acts as an antiseptic in the urinary tract and helps suppress the growth of bacteria that can cause urinary tract infections. Mandelic acid helps keep the urine acidic so the medicine can work effectively. Because this process depends on urine acidity, Mandelamine will not work properly if the urine is too alkaline.

Follow all directions given to you by your doctor and read all documents provided, including the full Prescribing Information, FDA-Approved Product Labeling, Instructions for Use, and Medication Guide before using Mandelamine. However, the following is a synopsis of the general guidelines for the use of Mandelamine:

• Mandelamine is taken by mouth, usually in divided doses throughout the day.
• It is commonly taken after meals to reduce upset stomach.
• Tablets should be swallowed whole with a full glass of water.
• Do not crush or chew coated tablets unless advised by your healthcare provider.
• Your doctor may recommend dietary changes or vitamin C to help keep urine acidic.
• Take Mandelamine exactly as prescribed. Do not take more or less than directed, and do not stop using it without medical advice, even if you feel well. This medication is used for prevention and may need to be taken long-term.

Some mild or common side effects of Mandelamine seen in clinical trials as compared to placebo include:

• Upset stomach.
• Nausea.
• Mild stomach pain.
• Diarrhea.
• Loss of appetite.

Some individuals may experience serious side effects while using Mandelamine. These side effects may require immediate medical attention. If you experience any of the following, contact your healthcare provider or seek emergency medical help:

• Skin rash or hives that may indicate an allergic reaction.
• Painful or difficult urination.
• Blood in the urine.
• Severe bladder irritation.
• Signs of liver problems such as dark urine or yellowing of the skin.

These are not all of the possible side effects of Mandelamine. You should always seek medical advice from your healthcare provider for any questions or concerns about your medical condition or treatment. Read all patient information, medication guides, or drug information sheets that come with this medication. You can also report adverse effects to the Food and Drug Administration at www.fda.gov/medwatch or 1-800-FDA-1088.

Before starting Mandelamine, it is crucial to discuss any existing health conditions with your healthcare provider. You should be sure that your healthcare provider is aware of all your medical conditions, including if you have:

• Liver disease.
• Renal impairment or kidney disease.
• Dehydration.
• A history of bladder irritation.
• Conditions that affect urine acidity.
• Mandelamine should be used with caution in people who cannot maintain acidic urine, as the medication may not be effective. Regular follow-up may be needed to check urine pH and overall response to therapy.

Mandelamine should not be used in patients with:

• Severe renal disease.
• Severe liver disease.
• Dehydration.
• Known hypersensitivity to methenamine mandelate or any of its components.

Your healthcare provider will determine if Mandelamine is safe for you based on your medical history and current condition.

Mandelamine does not provide immediate relief of urinary tract infection symptoms. It works gradually to suppress bacterial growth in the urine and is intended for long-term prevention. Its effectiveness depends on consistent use and maintaining acidic urine. Benefits are usually seen over time rather than immediately.

When Mandelamine is taken with other prescription drugs, over-the-counter medications, vitamins, and supplements, it may change how they work or increase the frequency or severity of side effects. Make sure that you tell your healthcare professional about anything that you are taking to avoid any negative drug interactions, including:

• Sulfonamides such as sulfamethoxazole, sulfadiazine, or sulfisoxazole, which may interact with formaldehyde and increase the risk of urinary tract irritation.
• Antacids or bicarbonate-containing products, which can raise urine pH and reduce effectiveness.
• Acetazolamide, which may make urine more alkaline.
• Prescription drugs that affect kidney function.
• Always use a reliable interaction checker and consult your healthcare provider before starting new medications or supplements.

Mandelamine is available as oral coated tablets. The dose and frequency depend on age, medical condition, and response to treatment.

It should be stored at room temperature, away from the reach of children or pets.

Mandelamine has been manufactured by various companies over time. Availability may vary depending on region and supplier.

Yes. Methenamine mandelate is the generic name for Mandelamine.

Do not stop taking Mandelamine without speaking to your healthcare provider. Stopping too soon may increase the risk of recurrent urinary tract infections. Your doctor will advise when and how to discontinue treatment safely.

Talk to your doctor if you are already pregnant or if you have any plans to become pregnant. Your healthcare provider will weigh the potential benefits and risks before recommending Mandelamine during pregnancy.
