Keflex, or cephalexin, is a common antibiotic used to treat various bacterial infections. Remember to always consult your doctor before starting any medication, including Keflex.
Common Uses
- Skin infections: Keflex effectively combats infections like impetigo and cellulitis.
- Respiratory tract infections: It can treat bronchitis and pneumonia (when caused by susceptible bacteria).
- Ear infections: Keflex is sometimes prescribed for otitis media (middle ear infection).
- Urinary tract infections: It’s effective against some bacteria causing UTIs.
Dosage varies depending on the infection’s severity and your doctor’s assessment. Follow your prescription instructions precisely. Complete the entire course of antibiotics, even if symptoms improve, to prevent recurrence.
Potential Side Effects
Like all medications, Keflex may cause side effects. These commonly include:
- Gastrointestinal issues: Nausea, diarrhea, and vomiting are possible.
- Allergic reactions: Rashes, itching, hives, or difficulty breathing require immediate medical attention.
- Yeast infections: Antibiotics can disrupt the natural balance of bacteria in the body, potentially leading to yeast infections.
Less common side effects include changes in urine color, increased thirst and a metallic taste. Report any unusual symptoms to your physician.
Drug Interactions
Certain medications can interact with Keflex. Disclose all medications, supplements, and herbal remedies to your doctor before taking Keflex to avoid potential complications. This includes anticoagulants such as warfarin.
Important Considerations
- Pregnancy and breastfeeding: Inform your doctor if you are pregnant, breastfeeding, or planning pregnancy before taking Keflex.
- Allergies: If you have penicillin allergies, inform your doctor before taking Keflex because it belongs to the cephalosporin class, a related group of antibiotics.
- Kidney function: People with impaired kidney function may require dosage adjustments.
Contact Your Doctor
This information is for general knowledge and does not substitute professional medical advice. Contact your physician or pharmacist for any concerns regarding Keflex or its use. They can provide tailored guidance based on your individual health needs and medical history.
Potential Side Effects and Adverse Reactions
Keflex, like all medications, can cause side effects. Most are mild and temporary. Common side effects include diarrhea, nausea, and vomiting. These usually resolve without intervention. However, if these persist or worsen, contact your doctor.
Less common but more serious side effects include allergic reactions. These can manifest as skin rash, itching, hives, or swelling of the face, lips, or tongue. In rare cases, Keflex can trigger a severe allergic reaction called anaphylaxis, requiring immediate medical attention. Seek immediate medical help if you experience any signs of a severe allergic reaction.
Keflex can also affect your digestive system, potentially causing pseudomembranous colitis, a serious bowel inflammation. Symptoms include severe diarrhea, stomach cramps, and fever. If you experience these, discontinue Keflex and seek medical advice immediately.
Kidney problems, though uncommon, are a potential risk, particularly in individuals with pre-existing kidney conditions. Your doctor should monitor your kidney function if you have a history of kidney disease. Increased risk of bleeding can occur in individuals who are already predisposed to bleeding disorders.
