Cephalexin, an antibiotic, may interact with certain medications, so caution is advised. It’s generally safe with many drugs, but combining it with blood thinners like warfarin can increase bleeding risks. Cephalexin may also reduce the effectiveness of oral contraceptives, so backup contraception is recommended. Avoid mixing with metformin, as it could elevate blood sugar levels. Always consult a healthcare provider before combining Cephalexin with other medications, especially for those sourcingcephalexin wholesale for clinics or pharmacies. Drug interactions vary based on individual health conditions. For safe use, disclose all medications to your doctor to prevent adverse effects.
