When dealing with drug interactions, the ways in which two or more drugs can affect each other's performance or cause side effects. Also known as medication interactions, they can turn a helpful prescription into a health risk if not understood.
Take Metformin, a first‑line oral diabetes drug that lowers blood sugar as an example. When you pair Metformin with Sitagliptin, a DPP‑4 inhibitor that boosts insulin release, the combo can improve glucose control, but it also raises the chance of gastrointestinal upset. Drug interactions like this illustrate why you need to know the pharmacokinetic profile of each medicine. Antibiotics, drugs that kill or stop bacteria add another layer—some antibiotics disturb gut flora, which can diminish the absorption of supplements, vitamins or minerals taken to support health. So, an antibiotic course might blunt the effect of a calcium supplement, leaving bone health at risk. These connections show that drug interactions encompass metabolic, digestive, and even hormonal pathways.
Understanding how common drugs like Metformin, Sitagliptin, antibiotics, or everyday supplements interact helps you avoid surprises at the pharmacy or clinic. In the list below you’ll find practical articles that break down specific combos, highlight warning signs, and give tips for talking with your doctor.
