Keflex Interactions: What You Need to Know

If you’re taking Keflex (cephalexin), knowing how it interacts with other drugs can save you from unwanted side effects or reduced effectiveness. Keflex is a common antibiotic used for bacterial infections, but mixing it with certain medications or supplements might cause problems. Let's break down the must-know facts on Keflex interactions so you can stay safe and get your best results.

Common Medications That Affect Keflex

Certain drugs can either make Keflex less effective or increase side effects. For example, probenecid, often used for gout, can slow down how your body gets rid of Keflex, leading to higher levels in your blood and a higher chance of side effects. On the other hand, medicines like metformin might need careful monitoring since antibiotics sometimes affect blood sugar control.

Also, if you’re taking blood thinners like warfarin, Keflex might increase bleeding risks. It’s smart to tell your doctor about all your current medications so they can adjust dosages or keep an eye out for issues.

Supplements and Foods to Watch Out For

Sometimes, it’s not just other drugs. Some supplements or foods may interfere with Keflex too. For instance, antacids containing magnesium or aluminum can reduce how much Keflex gets absorbed, which might weaken its infection-fighting power. It’s better to take Keflex a couple of hours apart from these antacids.

While Keflex doesn’t have many food restrictions, always follow your doctor’s advice. If you’re unsure, avoid alcohol because it can stress your liver and cause extra side effects alongside your antibiotic.

Remember, being upfront with your healthcare provider about everything you take allows them to guide you best. That way, you get the healing you need without surprises from dangerous interactions.
