Always inform your doctor about all medications you take, including over-the-counter drugs and supplements. This helps avoid dangerous interactions. Keflex, or Cephalexin, can interact with certain medications, such as anticoagulants like warfarin, increasing bleeding risk. Discuss this with your physician before starting Keflex.
Common Side Effects
Expect some mild side effects, such as nausea, diarrhea, and stomach upset. These are usually temporary. However, report persistent or severe diarrhea immediately; it could indicate a serious complication. A less common but significant side effect is allergic reaction. Watch for hives, swelling, difficulty breathing, or other symptoms. Seek immediate medical help if you experience an allergic reaction.
Less Frequent Side Effects
Less frequently, Keflex may cause dizziness or headache. Avoid driving or operating machinery if you experience these. Similarly, vaginal yeast infections can occur. If you notice any unusual vaginal discharge, contact your doctor. Finally, prolonged Keflex use can affect your gut flora, potentially leading to yeast overgrowth. Your doctor can advise on managing this.
