Product Details

Description

Keflex is a widely prescribed antibiotic that effectively treats various bacterial infections. It’s available in 250 mg and 500 mg capsules, taken orally every 6 to 12 hours, with or without food. It prevents bacteria from building a protective cell wall, causing them to break down and stop the infection from growing. Suitable for adults, seniors, and children, the dosage depends on age and infection severity. Nausea, diarrhea, and mild rash are common side effects. Severe symptoms require immediate medical attention. Store Keflex at room temperature, away from heat, moisture, and children. Always complete the full treatment course for best results.

Usage Guide

  • Take Keflex at the same time each day to maintain consistent medicine levels.

How It Works

Keflex (cephalexin) is a beta-lactam antibiotic that works by inhibiting bacterial cell wall synthesis. It binds to penicillin-binding proteins, preventing the bacteria from forming a strong cell wall. This causes the bacterial cells to weaken and burst, leading to their death. Since human cells lack cell walls, Keflex specifically targets bacteria without harming the body.

Side Effects

Common Keflex side effects may include:

  • Diarrhea
  • Nausea or vomiting
  • Stomach pain or cramps
  • Headache
  • Dizziness
  • Rash or itching

Serious (rare) Keflex side effects may include:

  • Severe allergic reaction (swelling, difficulty breathing)
  • Persistent or severe diarrhea
  • Unexplained bruising or bleeding
  • Jaundice
  • Seizures
  • Severe skin rash or blistering

Note: Contact your healthcare provider or doctor if you experience any serious symptoms or unusual changes.

Warnings

Before you order Keflex online, it's important to understand a few medical precautions to ensure safe and effective use.

  • Kidney Health: Keflex is processed through the kidneys, so if you have reduced kidney function or are on dialysis, your dosage may need adjustment. Regular monitoring helps avoid potential buildup or toxicity.
  • History of Intestinal Issues: Patients with a history of colitis or antibiotic-associated diarrhea should use Keflex cautiously. Some antibiotics can disrupt gut flora and may trigger a recurrence of symptoms.
  • Use During Pregnancy or Breastfeeding: Although Keflex is typically considered safe, pregnant or breastfeeding women should only use it under medical supervision.
Safety Guide

When you order Keflex from Canada, keeping these safety tips in mind will help ensure the medication works well and minimizes risks.

  • Consult Your Healthcare Provider: Always check with your doctor before starting Keflex to make sure it’s the right choice for your infection and medical history.
  • Follow Dosage Instructions Carefully: Take Keflex exactly as prescribed—do not skip doses or take extra, even if you start feeling better before finishing the course.
  • Avoid Sharing Medication: Keflex is prescribed specifically for you. Never share it with others, as their condition or allergies may differ.
Missed Dose

If you miss a dose of Keflex, take it when you remember. However, if it’s time for your next one, skip the missed dose and then continue your regular schedule. Avoid doubling up doses at once to make up for the missed dose.

Overdose

If you suspect an overdose of Keflex, seek medical attention immediately or contact the poison help line number at 1-800-222-1222. Symptoms may include severe stomach pain, diarrhea, or unusual weakness.
