Introduction to Fosirol Powder

Fosirol Powder belongs to a class of drugs called phosphonic antibiotics containing the active ingredient Fosfomycin. It is used to treat bacterial infections, particularly uncomplicated urinary tract infections (UTIs) in women caused by susceptible bacteria. It is effective against a wide range of gram-negative and gram-positive bacteria. This drug is also used to prevent possible infections before prostate surgical procedures in adult men. Administering the medication before the surgery can help reduce the risk of post-operative infections.

If you have a history of experiencing diarrhea after taking antibiotics, you must inform your physician before initiating the treatment. Certain antibiotics, including this drug, can sometimes cause gastrointestinal side effects like diarrhea, and this information helps your doctor assess any potential risks or alternatives. Fosirol Powder is generally not recommended for use in children under 12 years old. The safety and efficacy of this drug in younger children have not been well-established, and therefore, it is usually avoided in this age group.

Word of Advice

Take Fosirol Powder exactly as your physician prescribes and complete the full course of treatment, even if you start feeling better before the medication is finished. Incomplete courses of antibiotics can contribute to antibiotic resistance and the recurrence of infections. If you suspect you have a bacterial infection or UTI symptoms, it's necessary to consult your physician for proper evaluation and treatment recommendations.


Q 1. What infections does Fosirol Powder treat?

Fosirol Powder is primarily used to treat uncomplicated urinary tract infections (UTIs) caused by certain susceptible bacteria, particularly Escherichia coli (E. coli), which is a common pathogen responsible for UTIs. It may also be prescribed for other bacterial infections, but its use is generally limited to UTIs.

Q 2. How is Fosirol Powder administered?

Fosirol Powder is available in several forms, including oral granules, sachets, and intravenous (IV) preparations. For uncomplicated UTIs, it is often given as a single oral dose. A course of IV treatment may be prescribed for more severe or complicated infections.

Q 3. Can Fosirol Powder be used to prevent UTIs?

Fosirol Powder is primarily used for the treatment of UTIs, not for prevention. If you experience recurrent UTIs, your physician may suggest other preventive measures or medications.

Q 4. Is Fosirol Powder effective against antibiotic-resistant bacteria?

Fosirol Powder can still be effective against some antibiotic-resistant bacteria, including certain strains of multidrug-resistant E. coli. However, susceptibility testing is necessary to determine if the specific bacterial strain causing the infection is susceptible to this drug.

Q 5. Can I drink alcohol while taking Fosirol Powder?

It is generally recommended to avoid alcohol consumption while taking antibiotics, including Fosirol Powder. Alcohol can interfere with the effectiveness of antibiotics and may also exacerbate certain side effects.

Q 6. How to take fosirol powder?

Dissolve fosirol powder in a glass of water and drink immediately, at bedtime, 2 hours after meals.
