What Type of Antibiotic is Infectocef (Cefaclor)?

Infectocef is a prescription-only medication primarily used to resolve bacterial infections, containing the active ingredient Cefaclor. This compound is classified as a semisynthetic beta -lactam antibiotic, indicating its structure is derived from natural precursors but enhanced through chemical modification. The medication belongs to the family of cephalosporin antibiotics, specifically functioning as a second-generation cephalosporin. This positioning is clinically recognized for its effectiveness against a broad range of susceptible pathogens, underscoring its established role in antimicrobial therapy.


Composition and Available Forms of Infectocef

The active component, Cefaclor, is a single-ingredient product designed for oral administration. Infectocef is available in several dosage forms, including a conventional capsule, a liquid oral suspension for ease of administration, and an extended-release tablet. The extended-release tablet is specifically formulated to control the absorption rate of Cefaclor in the body, providing sustained therapeutic concentrations, which is a key distinguishing feature among the available formulations.


How Infectocef Works to Eliminate Bacteria

Infectocef achieves its general purpose through a rapid and highly specific bactericidal action, ensuring the destruction of the bacteria causing the infection. This function occurs because the cephalosporin interferes with the formation of the bacterial cell wall. Cefaclor prevents the crucial cross-linking of structural elements within the wall, effectively compromising the pathogen's integrity. This mechanism is key to managing bacterial infections because it directly eliminates the source of the illness.

What side effects are possible with Infectocef?

Possible Side Effects and Safety Information

The safety profile of Infectocef (Cefaclor) is structured around adverse reactions primarily affecting the gastrointestinal system, skin, and immune system. Regulatory documents classify side effects by their frequency of occurrence.

Classification Examples of Documented Adverse Reactions
Common (1% to 10%) Diarrhea, headache, eosinophilia, genital pruritus, and vaginal moniliasis.
Uncommon (0.1% to 1%) Serum sickness-like reaction (reported more frequently in children), skin rash, and urticaria.
Rare (0.01% to 0.1%) Transient elevations in liver enzymes, reversible hyperactivity, and somnolence (sleepiness).

The official label highlights the potential for Serious Adverse Reactions. These include severe hypersensitivity reactions such as anaphylaxis and severe cutaneous adverse reactions (e.g., Stevens-Johnson Syndrome). Additionally, the possibility of pseudomembranous colitis, which can occur during or up to several weeks after therapy, is documented in the regulatory safety information.

Population-Specific Safety Notes are defined in official labeling. Caution is advised for patients with renal impairment, as dosage adjustments may be required to mitigate the risk of neurotoxicity. The medicine is strictly contraindicated in individuals with a known severe allergy to the cephalosporin class of antibiotics, and caution is advised for those with a history of penicillin allergy due to documented cross-sensitivity.

Overdose and Emergency Response

Official Regulatory Information for Infectocef Overdose

The official regulatory profile for Infectocef (Cefaclor) overdose defines the expected presentation through a cluster of gastrointestinal manifestations. These include nausea, vomiting, epigastric distress, and diarrhea, with the severity of certain symptoms documented as dose-related. Other symptoms are likely secondary to an underlying disease state or other intoxication.

A significant concern in overexposure is the potential for serious neurological outcomes, such as seizures and neurotoxicity. Regulatory documents indicate this risk is exacerbated in patients with renal impairment, where the drug's prolonged half-life can lead to high plasma concentrations.

Immediate Emergency Action In the event of a suspected overdose, immediate medical attention must be sought. Emergency guidance mandates contacting emergency services immediately if the presentation includes a seizure, trouble breathing, or collapse. Management is symptomatic and supportive, focused on protecting the airway and supporting ventilation and perfusion. Meticulous monitoring of vital signs, blood gases, and serum electrolytes is required. While activated charcoal is noted as beneficial for decreasing absorption, official information confirms that no specific antidote is known, and standard procedures like hemodialysis have not been established as effective.


The overall overdose profile defines the condition through specific symptom clusters and links the potential for severe, life-threatening neurological complications directly to the presence of high drug concentrations. This structure strictly guides when urgent medical help must be sought based on the documented severity of the presenting signs and the required supportive response.

Therapeutic Uses of Infectocef

Quick Facts: Therapeutic Domains

  • Management of certain respiratory tract infections.
  • Treatment of specific skin and soft tissue infections.
  • Used for conditions affecting the urinary tract.
  • May be administered for certain cases of bacterial otitis media (ear infection).

Infectocef is indicated for the treatment of various infections caused by susceptible strains of bacteria. The medication assists in managing conditions affecting several body systems, including respiratory, integumentary, and urinary systems.

The authorized uses typically encompass the management of certain lower respiratory tract infections, such as pneumonia, when caused by identified susceptible bacteria. It is also utilized in managing acute bacterial exacerbations of chronic bronchitis. Additionally, Infectocef is indicated for certain uncomplicated skin and skin-structure infections, aiding in the resolution of the bacterial component of these conditions. It also has a role in the treatment of specific infections of the urinary tract, including complicated and uncomplicated presentations.

Furthermore, Infectocef may be used in the treatment of acute bacterial otitis media (an ear infection) in pediatric patients and other approved populations when deemed medically appropriate. The determination to use this medication must be based on the pathogen's confirmed susceptibility and the patient's specific clinical presentation.

Eligibility and Restrictions for Use

Who Can and Cannot Use Infectocef (Cefaclor)

Official regulatory information defines specific population eligibility rules for using Infectocef, based strictly on medical history and age criteria.

Contraindicated and Ineligible Populations

Infectocef is contraindicated and must not be used by patients with a known allergy or severe hypersensitivity reaction to cefaclor or to any other cephalosporin antibiotic. Caution is also warranted for individuals with a history of severe penicillin allergy due to the potential for cross-reactivity.

Use is formally not established and therefore generally ineligible for infants younger than one month of age. Furthermore, the extended-release tablet formulation is not established for children under 16 years of age.


Restricted and Conditional Use

Population Group Regulatory Status
Renal Impairment Use requires caution in patients with markedly impaired renal function.
Gastrointestinal History Use requires caution in individuals with a history of colitis or other gastrointestinal disease.
Pregnancy and Lactation Use is only advised if clearly needed; caution is recommended for both pregnant and nursing women.

Adults and pediatric patients one month of age and older are generally eligible for the immediate-release forms of Infectocef, provided no contraindications exist.

What should I know about interactions with other medicines?

The officially documented interaction profile for Infectocef (Cefaclor) focuses primarily on pharmacokinetic changes and specific pharmacodynamic effects, as described in regulatory labeling.

Drug-Drug and Substance Interactions

Interaction Category Official Regulatory Outcome
Altered Clearance Co-administration with Probenecid is officially documented to decrease the drug's renal tubular secretion. This pharmacokinetic interaction results in increased and prolonged serum concentrations of Cefaclor.
Anticoagulant Effect Concomitant use with Oral Anticoagulants (such as Warfarin) has been associated with an increased anticoagulant effect and, in some cases, an increase in prothrombin time.
Altered Absorption Aluminum- or Magnesium-containing Antacids diminish the extent of Cefaclor absorption. The regulatory restriction requires that these antacids must be administered at least one hour apart from the Cefaclor immediate-release forms.

Food and Testing Constraints

The presence of food decreases the peak plasma concentration (mathbfCmax) and delays the time to peak concentration (mathbfTmax) for the immediate-release capsule, though the total absorption (AUC) remains unchanged. Additionally, the use of Cefaclor may cause a false-positive reaction for glucose during specific urine tests (those using Benedict's or Fehling's solutions or Clinitest tablets). Caution regarding potential accumulation is noted for patients with renal impairment, particularly when combined with clearance-inhibiting agents.

Mechanism of Action

Infectocef functions through the irreversible inhibition of key bacterial enzymes known as penicillin-binding proteins (PBPs). These PBPs are critical transpeptidases responsible for the final cross-linking step in the construction of the bacterial cell wall's structural layer, the peptidoglycan.

Upon binding covalently to PBPs, Infectocef prevents the formation of a structurally intact cell wall. This specific pathway blockade immediately compromises the integrity of the bacteria, leading to a loss of osmotic stability. The subsequent mechanistic cascade results in the physical breakdown and elimination of the susceptible bacterial cells (lysis).

A secondary mechanistic domain involves the drug's inherent resistance to certain bacterial beta-lactamase enzymes, a common microbial defense. By avoiding this enzymatic hydrolysis, Infectocef maintains a sufficient concentration of active molecules to effectively engage and inhibit its PBP targets, thereby facilitating the sustained cell wall inhibition required for its full pharmacodynamic effect.

Dosage and Administration Information

Official Administration Guidelines for Infectocef (Cefaclor)

Infectocef is an orally administered antibiotic with specific usage instructions depending on the chosen formulation. The total duration of therapy is typically 7 to 10 days, but must be a minimum of 10 days when treating infections caused by beta-hemolytic streptococci. Completing the entire prescribed course is essential to proper use.


Dosing and Frequency

The standard adult dosing for the immediate-release (IR) forms (capsule or oral suspension) is usually 250 mg taken every 8 hours (three times daily). For more severe infections, this dose is typically increased to 500 mg taken every 8 hours.

The extended-release (ER) tablet is administered on a twice-daily schedule (every 12 hours), with doses typically ranging from 375 mg to 750 mg depending on the approved indication.


Administration Instructions

Feature Instruction
Immediate-Release Forms May be taken with or without food.
Extended-Release Tablets Must be taken with a meal and must not be crushed, cut, or chewed.
Oral Suspension Requires reconstitution with water and must be shaken well before each measured dose is administered.

Population-Specific Use

Dosage for pediatric patients is determined by body weight, calculated between 20 mg/kg/day and 40 mg/kg/day, divided into doses taken every 8 or 12 hours, not exceeding 1 g per day. No general adjustment to the adult regimen is typically required for patients with moderately impaired renal function. If a dose is missed, it should be taken as soon as remembered; otherwise, the missed dose should be skipped to resume the regular schedule.

Recent Clinical Evidence

Research evidence / Overview of studies for Infectocef

The evidence for the authorized uses of Infectocef (Cefaclor) is based primarily on clinical research, as documented in official sources. The goal of this research was to explore how symptoms evolved and was to evaluate the measured outcome of pathogen clearance in specific patient groups. This overview describes the research landscape, including what was studied and what remains uncertain, based on regulatory documentation.


Evidence for use in Respiratory Tract Infections and Otitis Media

Research was conducted for its use in conditions like pneumonia, acute exacerbations of chronic bronchitis (AECB), and otitis media (ear infection), which are all conditions associated with acute or disruptive episodes. These studies were applied in research contexts involving fluctuating or unstable symptoms, where researchers measured outcomes related to physical discomfort and recovery from the acute illness.

For pneumonia and AECB, the research base includes both Comparative Clinical Trials and Open-Label Trials focused on adult populations. These studies were used in research exploring how symptoms change over time, tracking the resolution of infection signs and the Bacteriological Eradication (elimination of the responsible bacteria). Findings describe patterns observed in the studies related to Clinical Response and the measured rate of pathogen clearance from the respiratory system.


Evidence for use in Urinary and Skin Infections

The research examined Infectocef use in studies involving urinary tract infections (UTIs) and uncomplicated skin and skin structure infections (SSSIs).

In research scenarios related to UTIs, Clinical Trials and Bacteriological Evaluation Studies were evaluated in both adult and pediatric populations. These studies monitored outcomes linked to inflammatory or irritative states and focused heavily on achieving Bacteriological Eradication (clearing bacteria from the urine). Follow-up was observed in some studies for up to four weeks to assess long-term clearance.


What is Still Uncertain About the Research

Research highlights what is known — and what is still uncertain regarding Infectocef.

Key limitations in the research include the fact that the profile of the measured effects is not established for infants less than one month of age. Furthermore, data for certain groups remain insufficient, and research was observed in some studies to lack robust data establishing its role in the secondary prevention of subsequent conditions (such as rheumatic fever following specific streptococcal infections). This area represents an evidence gap where research is ongoing or data are still emerging.
