Keflex (Cephalexin) Patient Information Guide in Thailand

What is Keflex?

Keflex (Cephalexin) is an antibiotic medication belonging to the cephalosporin class, commonly prescribed to treat various bacterial infections. In Thailand, like other markets, this medicine is used to target susceptible strains of bacteria causing issues such as skin, bone, ear, and Throat Infections. The active substance, Cephalexin, is typically available in the oral pill (capsule or tablet) form. It functions by stopping the growth of bacteria, allowing the body's immune system to clear the infection effectively.

Who Should Use Keflex?

Patients who meet the clinical profile for bacterial infections successfully treated by Cephalexin are candidates for this medication.

• Individuals diagnosed with susceptible skin and soft tissue infections.
• Patients experiencing specific types of respiratory tract infections, such as Bronchitis or Pneumonia caused by sensitive bacteria.
• People with Urinary Tract Infections (UTIs) confirmed to be caused by bacteria sensitive to cephalosporins.
• Healthy adults and children (where appropriate based on specific dosing) requiring this antibiotic treatment.

How Does It Work?

Cephalexin works by interfering with the synthesis of the bacterial cell wall, which is crucial for the survival of many bacteria. Imagine the bacterial cell wall as a protective brick structure; Cephalexin prevents the final "bricks" from being properly linked together. This structural weakness causes the bacterial cell to break apart and die. Because human cells do not possess this specific type of cell wall, Cephalexin targets the bacteria specifically, minimizing harm to human tissue. This medicine is effective only against bacteria, not viruses like those causing the common cold or flu.

Why Choose Keflex?

Keflex, specifically Cephalexin, is widely utilized globally due to its excellent spectrum of activity against common pathogens and its favorable safety profile when used correctly. Since the generic version of Cephalexin is readily available, it often provides a cost-effective treatment option compared to newer or more specialized antibiotics. Its effectiveness against many common community-acquired infections makes it a frequent initial choice for bacterial management.

Dosage, Administration, Lifestyle and Dietary Recommendations

Recommended Dosage

The dosage strength often starts at 250mg or 500mg, depending on the severity and type of infection being treated. Dosages are typically divided and taken throughout the day as directed, usually every six or twelve hours. It is vital to adhere strictly to the regimen determined by the healthcare provider.

How to Take

For optimal absorption and tolerance, Keflex (Cephalexin) can be taken with or without food. Swallow tablets or capsules whole with a full glass of water. Completing the entire course is necessary even if symptoms improve rapidly.

Missed Dose

If you realize you missed a dose soon after the scheduled time, take it immediately. However, if it is almost time for your next scheduled dose, skip the missed one entirely. Never take a double dose to make up for a missed administration.

Overdose

An overdose of Cephalexin is rare but may cause severe gastrointestinal upset or neurological signs. If an overdose is suspected, seek immediate medical attention or contact local emergency services.

Special Populations

• Elderly Patients: May require lower initial doses, especially if there is pre-existing kidney impairment, as the drug is cleared primarily by the kidneys.
• Children: Dosing is weight-based; suspension forms are often used for ease of administration rather than pills.
• Impaired Organ Function: Patients with significant kidney problems require dose adjustments based on renal function tests, as Cephalexin accumulates in the body during kidney dysfunction.

Lifestyle & Diet

Avoid excessive intake of alcohol while taking any antibiotic, including Cephalexin, as it can increase potential side effects like dizziness or Nausea. Generally, no specific dietary restrictions are mandated, but maintaining good hydration supports overall organ function during infection treatment.

Precautions and Warnings

Cephalexin must be used with caution in individuals with a known allergy history to penicillin or other cephalosporins due to the risk of cross-reactivity. Prolonged use can sometimes lead to the overgrowth of non-susceptible organisms, potentially causing secondary infections like Clostrioides difficile-associated Diarrhea (CDAD). Monitor for persistent or severe diarrhea during and after treatment.

Drug Interactions

Potential Side Effects

Common Side Effects

These typically resolve once the medication course is finished:

• Nausea or vomiting
• Mild diarrhea
• Stomach discomfort/cramping
• Headache

Less Common Side Effects

• Dizziness or lightheadedness
• Vaginal yeast infection (thrush)
• Mild skin rash or itching

Serious Side Effects

If you experience any of the following, seek prompt medical guidance:

• Severe, watery, or bloody diarrhea (sign of CDAD)
• Signs of an allergic reaction: Hives, difficulty breathing, swelling of the face, lips, or throat.
• Unusual bruising or unusual bleeding.
• Yellowing of the skin or eyes (jaundice).

Who Should Avoid This Medication?

Cephalexin is strictly contraindicated in patients who exhibit:

• Known hypersensitivity (severe allergy) to Cephalexin.
• Known immediate or severe hypersensitivity reaction to any other cephalosporin antibiotic.
• Documented history of severe GI disease, such as Pseudomembranous Colitis related to past antibiotic use.

Storage Instructions

• Store Keflex at controlled room temperature, away from excessive heat and direct moisture.
• Keep the container tightly closed when not in use.
• Ensure the product is stored securely, out of reach of children.
• Do not use the medication if the expiry date listed on the packaging has passed.

Keflex (Cephalexin) Alternatives

Frequently Asked Questions

How quickly does Keflex start to work against an infection?

Keflex begins inhibiting bacterial growth relatively fast, usually within 1 to 2 days of starting the course. However, the noticeable improvement in how you feel (reduction in fever or Pain) might take slightly longer, often 3 to 4 days. Do not stop taking it just because you feel better prematurely.

Can I drink coffee or tea while taking Cephalexin?

Yes, moderate consumption of coffee or tea is generally acceptable while taking Cephalexin. Unlike some antibiotics, Cephalexin absorption is not significantly impacted by caffeine or typical beverage consumption. Focus instead on drinking plenty of plain water to keep hydrated.

What should I do if the rash caused by Keflex does not go away?

If a rash that started after beginning treatment persists or worsens after stopping the antibiotic, you must consult a healthcare professional immediately. A persistent rash might indicate a delayed allergic reaction or another skin condition requiring separate management.

Is Keflex effective against illnesses caused by viruses?

No, Keflex is only effective against bacterial infections. It has absolutely no effect on viruses, meaning it cannot treat the common cold, flu, or most sore throats caused by viral agents. Using antibiotics unnecessarily contributes to bacterial resistance.

How long after finishing the Keflex course can I expect to feel completely well?

While the infection is cleared when you finish the medication, your body needs time to fully recover its normal energy levels, especially if the infection was severe. Expect full recovery within one week after completing the full course. Consult your doctor if severe symptoms persist beyond this timeframe.

Is Cephalexin the same as penicillin?

No, Keflex (Cephalexin) is related to penicillin but is chemically distinct. They belong to different subclasses of beta-lactam antibiotics. People allergic to penicillin may still react to Cephalexin, though the risk is generally low (around 1-2%).

Can infants safely take Cephalexin suspension?

Dosing for infants relies heavily on accurate weight measurement and specific pediatric guidelines, so it must only be administered under strict medical recommendation. The formulation for infants is usually a liquid suspension.

Glossary

• Cell Wall Synthesis: The biological process by which bacteria build the rigid outer layer necessary for their structure and survival.
• Beta-Lactam Antibiotics: A large class of antibiotics, including penicillins and cephalosporins, characterized by a specific chemical structure that inhibits bacterial cell wall formation.
• Cross-Reactivity: The immunological phenomenon where the body reacts to a substance (like Cephalexin) because it is structurally similar to another substance it is already allergic to (like Penicillin).
