Pill Splitting: What You Need to Know Before Cutting Your Medication

When you pill splitting, the practice of cutting a tablet in half to adjust dosage. Also known as tablet splitting, it’s a common way people stretch their prescriptions, lower costs, or fine-tune their dose—especially with high-priced brand-name drugs or when switching to generics. But this isn’t just a money trick. It’s a medical decision with real risks, and not every pill is meant to be cut.

Some medications, like extended-release pills, drugs designed to release slowly over hours, can become dangerous if split. Cutting them may cause the full dose to flood your system at once. Others, like enteric-coated tablets, pills with a protective shell that prevents stomach irritation, lose their function when broken open. Even generic drugs, medications approved by the FDA to work like brand-name versions, can vary slightly in shape or hardness, making splitting uneven or unreliable. The FDA doesn’t approve all pills for splitting, and manufacturers rarely test how stable the halves are after cutting.

People often split pills to match a lower dose—like cutting a 20mg tablet in half to get 10mg—instead of buying two different strengths. It works fine for some drugs, like certain blood pressure pills or antidepressants, especially if they have a score line. But if you’re splitting a pill without a score, using a knife or scissors, or if the pill crumbles, you’re risking an inaccurate dose. That’s why a pill cutter, a simple tool designed to split tablets evenly is a must. It’s cheap, easy to use, and keeps you from guessing how much you’re taking. And remember: never split pills that are time-released, coated, or labeled "do not crush or split." Your pharmacist can tell you which ones are safe.

There’s also a big difference between splitting pills for cost savings and splitting them because your doctor adjusted your dose. If you’re cutting pills on your own without medical advice, you’re playing with your health. Some medications have a narrow therapeutic index—meaning the difference between a helpful dose and a harmful one is tiny. That’s why neurologists and cardiologists often warn against splitting drugs like warfarin or levothyroxine, even if they look like they can be cut. The same goes for drug dosage, the exact amount of medicine your body needs to work safely. A 5% error might not matter for a vitamin, but it could mean a stroke or a seizure with other meds.

Before you grab your knife or pill cutter, ask your doctor or pharmacist: Is this pill safe to split? Does it have a score line? Will splitting affect how it works? And is there a lower-strength version available? Most of the time, the answer is yes—and you’ll avoid the guesswork. But if you’re already splitting pills, don’t assume it’s fine just because you’ve done it for years. Medications change. Your body changes. And what worked last year might not be safe today.

The posts below cover real-world cases where pill splitting made a difference—both good and bad. You’ll find stories from people who saved hundreds a year by splitting their meds, others who ended up in the ER from uneven doses, and expert advice on when to use a pill cutter and when to avoid it altogether. Whether you’re trying to stretch your budget, manage side effects, or just understand why your doctor said no to splitting, these articles give you the facts without the fluff.
