Focin (1g) 1 Injection

Fosfomycin primarily targets bacterial cell wall synthesis by inhibiting the first step of peptidoglycan biosynthesis. It acts as a phosphoenolpyruvate (PEP) analog, irreversibly binding to the active site of enolpyruvyl transferase (MurA), an essential enzyme in the synthesis of the peptidoglycan layer. This binding inhibits the enzyme's activity, preventing the formation of the peptidoglycan building blocks, thus disrupting cell wall synthesis and leading to bacterial cell lysis.

The following are the uses of Fosfomycin 1g injection:

• Used for treating complicated urinary tract infections caused by susceptible bacteria.
• Used for bone and joint infections, especially those involving Enterobacteriaceae.
• Used as an alternative treatment for bacterial infections in patients allergic to penicillin.
• Used for the treatment of bacterial endocarditis, particularly in cases caused by Enterococcus.
• Used for intra-abdominal infections and peritonitis when caused by susceptible organisms.
• Used for the treatment of bacterial infections in individuals with impaired immune systems.
• Used to eliminate certain types of bacteria from the gut before a medical procedure.

In the case of an overdose of Fosfomycin 1g injection, prompt medical attention is necessary. Symptoms may include gastrointestinal disturbances, such as nausea, vomiting, and diarrhea. Additionally, an overdose could lead to electrolyte imbalances and potential kidney issues. Treatment involves managing these symptoms and providing supportive care. It is crucial to seek medical advice and follow the prescribed dosage to minimize the risk of adverse effects.

In the case of a missed dose of Fosfomycin 1g injection, it is important to administer the medication as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not double the dose to make up for a missed one, as this may increase the risk of side effects. If you miss multiple doses, contact your healthcare provider for guidance on how to safely resume the medication and ensure the best treatment outcome.

To administer Fosfomycin 1g injection, prepare the medication by drawing the entire contents of the vial into a syringe, then inject it slowly into a muscle or vein as directed by your healthcare professional, ensuring the injection is given under aseptic conditions and following proper injection techniques.

• Should not be administered to patients with a known allergy to Fosfomycin or other phosphonic acid antibiotics.
• Not suitable for patients with severe kidney impairment (as dosage adjustments are necessary).
• Contraindicated in patients with a history of hypersensitivity reactions to other antibiotics in the same class (such as penicillins).
• Should be avoided in patients with severe gastrointestinal disorders or a history of gastrointestinal surgery, as it may affect drug absorption.
• Not recommended for patients with active systemic viral infections, as it is only effective against bacterial infections.
• Should not be used for prolonged periods without monitoring, as it may lead to the development of antibiotic-resistant bacteria.
• Contraindicated in patients with a history of severe or life-threatening allergic reactions to any medication.

The side effects of Fosfomycin 1g injection may include:

• Nausea and vomiting
• Diarrhea
• Skin rashes or itching
• Dizziness
• Headache
• Vaginal itching or discharge
• Genital irritation
• Allergic reactions (rare)

Following are the precautions and warnings for Fosfomycin 1g Injection:

• This medication should not be used in patients with known hypersensitivity or allergy to fosfomycin or other components of the injection.
• Fosfomycin should be used with caution in patients with impaired kidney function, as dosage adjustments may be necessary.
• Prolonged use may lead to the development of superinfections or antibiotic-resistant bacteria; monitor patients closely.
• Caution is advised in patients with a history of gastrointestinal disorders, as it may cause diarrhea or gastrointestinal disturbances.
• It should not be mixed with other medications in the same intravenous line due to potential compatibility issues.
• Fosfomycin may interfere with certain laboratory tests, especially those involving glucose levels, so inform your doctor if you are undergoing any tests.
• Pregnant and breastfeeding women should use this medication only if clearly needed and under medical supervision, as the risks and benefits should be carefully considered.
• Always complete the full course of treatment as prescribed by your healthcare provider, even if symptoms improve before completion.

Following are the drug interactions for Fosfomycin 1g injection:

• Probenecid may decrease the renal excretion of fosfomycin, potentially increasing its serum levels.
• Fosfomycin may reduce the absorption of cyclosporine, leading to decreased cyclosporine levels.
• It can decrease the effectiveness of oral contraceptives, so alternative methods of contraception are recommended during treatment.
• Antacids containing aluminum, magnesium, or calcium may reduce the absorption of fosfomycin when taken simultaneously.
• Concomitant use with metformin may increase the risk of lactic acidosis, especially in patients with renal impairment.
• The efficacy of live attenuated vaccines, such as the typhoid vaccine, may be reduced during and shortly after fosfomycin treatment.
• Fosfomycin may interact with anticoagulants, affecting their metabolism and potentially altering their effects.

Following are the food interactions for Fosfomycin 1g injection:

• Fosfomycin should be taken on an empty stomach, at least 1 hour before or 2 hours after meals, as food can decrease its absorption and effectiveness.
• Avoid consuming dairy products, such as milk, cheese, or yogurt, within 1-2 hours of taking Fosfomycin as calcium can bind to the medication and reduce its absorption.
• Alcohol consumption is not recommended during treatment with Fosfomycin, as it may increase the risk of gastrointestinal side effects and affect the healing process.
• Grapefruit and grapefruit juice should be avoided as they can interfere with the metabolism of some medications, potentially affecting the effectiveness of Fosfomycin.
• Caffeine intake should be limited as it may increase the risk of side effects, particularly gastrointestinal disturbances and nervous system stimulation.
• Avoid high-fat meals as they may delay the absorption of Fosfomycin, leading to reduced effectiveness.
• Stay well-hydrated and maintain a balanced diet to support overall health and recovery during the course of treatment.
• Always follow the dosage instructions provided by your healthcare professional, and inform them about any dietary concerns or potential interactions.

Fosfomycin 1g injection should be stored in a controlled environment, preferably between 68°F and 77°F (20°C and 25°C), with brief excursions permitted between 59°F and 86°F (15°C and 30°C). Protect the injection from light and store it in its original packaging to maintain integrity. It is crucial to keep the medication away from children and pets. When disposing of unused or expired Fosfomycin injection, do not throw it into the trash or pour it down the drain. Contact your healthcare provider or pharmacist for guidance on safe disposal methods to minimize any potential environmental impact.
