What Are Lixen Cephalexin Tablets?

Lixen is a brand of Cephalexin, a first-generation cephalosporin antibiotic.The 300 mg tablet form is especially useful for medium to large cats or when a higher dose is required.

These tablets are prescription-only and are administered orally.

• Shape: Oblong or oval depending on manufacturer
• Flavored Variant: Some Lixen tablets come with a palatable flavor to ease feline administration

Mechanism of Action

It binds to specific penicillin-binding proteins (PBPs) inside the bacterial cell wall, preventing the final cross-linking of peptidoglycan strands.

Lixen Cephalexin 300 mg is used in cats primarily to treat infections caused by susceptible bacteria. These include:

 Skin and Soft Tissue Infections

• Pyoderma (bacterial skin infections)
• Abscesses from fights
• Wounds and lacerations

Urinary Tract Infections (UTIs)

• Cystitis
• Bacterial urethritis

Respiratory Tract Infections

• Rhinitis
• Sinusitis
• Bronchitis

Bone and Joint Infections

• Osteomyelitis (less common but documented)

Post-Surgical Prophylaxis

Dosage and Administration of Lixen Cephalexin 300 mg Tablets for Cats

Overview

Administering the correct dose of Lixen Cephalexin 300 mg Tablets is essential to ensure therapeutic effectiveness while minimizing side effects.

Standard Dosage Guidelines

The general recommended dosage for Cephalexin in cats is:

Administered orally every 8 to 12 hours (usually twice daily)

This dosage may be adjusted based on:

• Type of infection (e.g., UTI vs. skin infection)
• Duration of treatment (short-term vs. long-term)
• Severity and chronicity
• Individual health conditions (e.g., kidney impairment)

Dosage Based on Body Weight

Important: Tablets may be halved or quartered depending on dosing requirements. Consult your vet before splitting tablets.

Frequency and Duration of Treatment

• Typical Frequency: Every 12 hours (BID)
• Typical Duration: 7–14 days, depending on infection and response
• Skin and Soft Tissue Infections: 7–10 days
• Urinary Tract Infections: 10–14 days
• Post-surgical Prophylaxis: 5–7 days
• Bone or Joint Infections: Up to 4–6 weeks (with close vet supervision)

How to Administer the Tablet

1. Direct Pilling: Place the tablet at the back of the tongue and gently hold the cat’s mouth closed until swallowed. Follow with water or food.
2. Crushing (if vet-approved): Some cats may refuse whole tablets.

• Lixen can be given with or without food.
• Administering with food may reduce gastrointestinal upset such as nausea or vomiting.

Monitoring During Therapy

Especially during long-term treatment or in cats with pre-existing conditions, veterinarians may recommend:

• Renal function monitoring (BUN, creatinine)
• Liver function tests (ALT, AST)
• Complete blood count (CBC)
• Follow-up cultures, especially for UTIs or skin infections

Hygiene and Handling Tips for Owners

• Wash hands after administering the tablet
• Store unused tablets in a dry, cool place out of pet and child reach

Safety, Contraindications & Precautions of Lixen Cephalexin 300 mg Tablets for Cats

General Safety Overview

Contraindications

Lixen Cephalexin Tablets should not be used in the following situations:

1. Known Allergy to Cephalexin or Cephalosporins
   • Cats with hypersensitivity to cephalosporin antibiotics (and possibly penicillins, due to cross-reactivity).
   • Signs of allergy may include facial swelling, hives, or anaphylaxis.
2. Previous Severe Adverse Reaction
   • Any history of severe vomiting, seizures, or life-threatening reactions linked to prior use of beta-lactam antibiotics.
3. Do Not Use in Rabbits or Rodents

1. Use with Caution in Cats with Kidney Disease
   • Cephalexin is eliminated via the kidneys; dosage adjustments may be necessary.
   • Regular renal function monitoring is advised.
2. Monitor in Elderly Cats
   • Aging cats may have reduced metabolic or renal function, which can influence drug clearance.
3. Pregnancy and Lactation
   • Use only if clearly needed. Although studies suggest low fetal risk, consult your vet before use in pregnant or nursing cats.
4. Concurrent Illness
   • Conditions such as liver disease, diabetes, or chronic gastrointestinal issues may require individualized treatment plans.
5. Hydration and Nutrition
   • Ensure your cat maintains adequate fluid intake and nutrition throughout antibiotic therapy to reduce risks of GI upset and renal strain.

Clinical Research and Evidence

Lixen Cephalexin 300 mg Tablets have been widely studied for their safety, efficacy, pharmacokinetics, and clinical effectiveness in feline medicine.

Pharmacokinetics in Cats

Studies show that cephalexin is rapidly absorbed after oral administration, reaching peak levels within 1–2 hours. It has a half-life of 2.5–3.5 hours and is excreted mainly through the urine, making it effective for urinary tract infections.

Skin and Soft Tissue Infections

A clinical trial published in Veterinary Dermatology (2016) demonstrated that over 90% of cats with pyoderma and wounds treated with Cephalexin improved within 7–10 days, with minimal side effects.

Urinary Tract Infections (UTIs)

Research in the Journal of Feline Medicine and Surgery (2019) found Cephalexin to be 83% effective in treating feline UTIs. It performed comparably to enrofloxacin but with fewer gastrointestinal side effects.

Bacterial Sensitivity

However, it shows limited activity against Proteus and Pseudomonas, making bacterial culture and sensitivity testing essential.

Conclusion

Lixen Cephalexin Tablets 300 mg for Cats provide a reliable and potent option for treating various bacterial infections in cats, such as skin injuries, abscesses, urinary tract infections, and respiratory issues.Backed by strong clinical evidence and decades of veterinary use, Cephalexin remains a go-to antibiotic for veterinarians due to its broad-spectrum efficacy, well-tolerated profile, and affordable accessibility. When administered under veterinary guidance, Lixen provides rapid relief from symptoms, controls infection progression, and promotes a full recovery.
