Fortaz Information

Fortaz at CanadaPharmacyOnline.com

The manufacturer of Fortaz in Canada was historically GlaxoSmithKline Inc. (GSK). While the brand-name Fortaz has a long history in the Canadian market, its status has transitioned as newer treatment protocols and high-quality generics have emerged. In international markets, such as the United States, it is also associated with manufacturers such as Teligent Pharma or sold under the brand name Tazicef.

The generic ceftazidime is not currently unavailable (at this pharmacy).

Dosage:

Fortaz is available in the following injectable strengths:
• Powder for Solution (Vials): 1 g and 2 g.

The standard adult dosage is 1 to 2 g, administered every 8 to 12 hours, depending on the severity of the infection. For children and neonates, the dose is calculated by the doctor based on the child's weight and age.

Usage:

Fortaz is a potent, third-generation cephalosporin antibiotic used to treat a wide range of serious or life-threatening bacterial infections. It is particularly valued in clinical settings for its effectiveness against Pseudomonas aeruginosa, a difficult-to-treat bacterium. Doctors prescribe Fortaz for lower respiratory tract infections (including pneumonia in patients with cystic fibrosis), skin and soft tissue infections, bone and joint infections, and complicated urinary tract infections. It is also a critical treatment for life-threatening conditions such as bacterial meningitis, peritonitis, and sepsis (blood poisoning). Because it is a broad-spectrum antibiotic, it can fight many types of bacteria simultaneously. However, it will not work for viral infections like the common cold or flu.

Mechanism of Action
Ceftazidime, the active agent in Fortaz, works by disrupting the synthesis of the bacterial cell wall, which is essential for bacterial structural integrity and survival. It acts as a bactericidal agent by binding to and inhibiting specific enzymes known as penicillin-binding proteins (PBPs), particularly PBP-3 in gram-negative bacteria. These proteins are responsible for the final stages of cross-linking the peptidoglycan layer, which acts as the "mesh" of the cell wall. By blocking this process, Fortaz prevents bacteria from forming a functional cell wall, leading to bacterial cell rupture and death (lysis). Furthermore, Fortaz is highly stable against many beta-lactamases (enzymes produced by some bacteria to deactivate antibiotics), making it effective against several resistant strains.

Take Fortaz exactly as your doctor prescribes, following the instructions in the product monograph. It is essential to complete the full course of treatment, even if you start to feel better, to ensure the infection is completely eradicated and to prevent antibiotic resistance.

The information below summarizes some, but not all, potential side effects, risks, and interactions. Before starting Fortaz, it is essential to discuss all possible side effects, risks, and interactions with your doctor or pharmacist.

Side Effects:

The information below outlines potential side effects of Fortaz (ceftazidime). It is not an exhaustive list, and individual reactions can vary.

Common side effects: These are common side effects of Fortaz; other side effects are possible. Contact your doctor promptly if any side effects are persistent, worsening, or concerning, or if you experience any other concerning symptoms.
• Diarrhea
• Headache or dizziness
• Mild skin rash or itching
• Nausea or vomiting

Contraindications:

The following is not an exhaustive list of contraindications. Before starting Fortaz, it is crucial to discuss all your medical conditions, past and present, and all medications you are taking with your doctor or pharmacist.

Do not take Fortaz/ceftazidime if:
• Allergies: You have a known hypersensitivity to ceftazidime or other cephalosporin antibiotics (e.g., Ceftriaxone, Keflex).
• Severe Penicillin Allergy: Use with extreme caution if you have a history of severe, immediate allergic reactions to penicillin, as cross-reactivity can occur.

Tell your doctor about all of your medical conditions, past and present, before starting Fortaz. This is crucial as certain conditions affect the drug's safety.
• Gastrointestinal Disease: Especially a history of colitis.
• History of Seizures: Use with caution, as certain antibiotics can lower the seizure threshold.
• Kidney Disease: The dose must be adjusted if your kidney function is impaired to prevent drug accumulation and neurological side effects.

Drug Interactions:

Before taking Fortaz, discuss all potential risks and interactions with your doctor or pharmacist. For complete and up-to-date information, please visit the consumer information at https://dhpp.hpfb-dgpsa.ca/dhpp/resource/43080/consumer-information.

Provide your doctor with a complete list of all your medications, including prescriptions, over-the-counter (OTC) drugs, vitamins, herbal supplements, recreational drugs, and any significant dietary changes, as these may interact with Fortaz. Fortaz may interact with other medicines, including but not limited to:
• Aminoglycosides: Using Fortaz with antibiotics like gentamicin may increase the risk of kidney damage.
• Chloramphenicol: May have antagonistic effects, reducing Fortaz's efficacy.
• Live Bacterial Vaccines: Like the typhoid or BCG vaccine, which may be less effective if taken during antibiotic treatment.
• Oral Contraceptives: Antibiotics may slightly decrease the effectiveness of birth control pills.
• Potent Diuretics: Drugs like furosemide (Lasix) can also increase the risk of kidney toxicity when combined with Fortaz.

Pregnancy and Breastfeeding:

Fortaz is generally considered safe for use during pregnancy only if clearly needed. It has been used for many years without evidence of harm to the fetus. Small amounts of the drug pass into breast milk. While unlikely to harm a nursing infant, consult your doctor before breastfeeding while on this medication. Inform your doctor if you are pregnant, planning to become pregnant, or if you are breastfeeding.

Use in Children:

Fortaz is approved for use in pediatric patients, including neonates. For children, the medical team carefully calculates the dose based on weight, age, and the severity of the infection.
