Need information on Cephalexin? Start with dosage: Adults typically take 250-500mg every 6 hours, adjusted based on infection severity and your doctor’s assessment. Children’s dosages are calculated by weight and must be determined by a pediatrician.
This antibiotic targets a broad range of bacterial infections, including skin infections, respiratory tract infections, and urinary tract infections. However, Cephalexin’s effectiveness depends heavily on the specific bacteria causing the infection. A culture test helps confirm the correct diagnosis and ensures the antibiotic will work.
Remember potential side effects: diarrhea, nausea, and stomach upset are common. More serious reactions are rare but include allergic reactions such as rash or hives. Seek immediate medical attention if you experience any severe allergic reaction. Always inform your doctor about all medications you’re currently taking, including over-the-counter drugs and supplements, to avoid drug interactions.
Complete your prescribed course of Cephalexin, even if you start feeling better before finishing all the medication. Stopping early increases the risk of antibiotic resistance. Your doctor can provide further guidance on duration and specific instructions.

Potential Side Effects and Precautions
Cephalexin, while generally safe, can cause side effects. Common reactions include diarrhea, nausea, and vomiting. These usually are mild and resolve without treatment. However, persistent or severe gastrointestinal upset warrants immediate medical attention.
Allergic Reactions
A serious, though rare, side effect is an allergic reaction. Symptoms include rash, hives, itching, swelling of the face, lips, or tongue, and difficulty breathing. Seek immediate medical help if you experience any of these. Prior antibiotic allergies should be disclosed to your doctor before starting Cephalexin.
Other Potential Side Effects
Less common side effects include headache, dizziness, and vaginal yeast infections. Prolonged use may also increase the risk of *Clostridium difficile* infection, causing severe diarrhea. If you notice unusual vaginal discharge or severe, persistent diarrhea, contact your physician.
Inform your doctor about all medications you are taking, including over-the-counter drugs and supplements, as interactions are possible. Pregnant or breastfeeding women should discuss Cephalexin use with their doctor before starting treatment. Kidney or liver problems may require dose adjustments. Finally, always follow your doctor’s instructions for dosage and duration of treatment.
Interactions and Considerations with Other Medications
Always inform your doctor or pharmacist about all medications you’re taking, including over-the-counter drugs, vitamins, and herbal supplements. This includes prescription drugs, even if you only take them occasionally. Cephalexin can interact with certain medications, potentially reducing their effectiveness or increasing the risk of side effects.
Antacids and other medications affecting stomach acid:
Taking cephalexin with antacids or medications that reduce stomach acid can decrease cephalexin absorption. Ideally, separate the administration of cephalexin from these medications by at least two hours. Your doctor can provide tailored advice based on your specific medications and health condition.
Warfarin:
Cephalexin may increase the effects of warfarin (a blood thinner), potentially leading to an increased risk of bleeding. Close monitoring of your INR (International Normalized Ratio) is crucial if you’re on warfarin. Your physician might need to adjust your warfarin dosage. Regular blood tests will be necessary.
Oral contraceptives:
Some reports suggest cephalexin might reduce the effectiveness of oral contraceptives. While further research is needed, discuss this potential interaction with your doctor, especially if you are concerned about unplanned pregnancy. They might recommend alternative birth control methods during cephalexin treatment.
