Many people in Australia and around the world are cutting pills in half to save money on prescriptions. It sounds simple: buy a 40mg tablet instead of two 20mg ones, split it, and get the same dose for less. But splitting pills safely isn’t just about grabbing a knife and a pill. Do it wrong, and you could end up with too little-or too much-medication. That’s not just a waste of money. It’s a risk to your health.
Why Pill Splitting Saves Money
Pharmaceutical companies often price higher-dose pills at a fraction of the cost of buying two lower-dose pills. For example, a 40mg atorvastatin tablet might cost $4.27, while two 20mg tablets cost $3.48 each-totaling $6.96. Splitting the 40mg tablet saves you nearly 38%. That’s $2.69 per dose, or over $1,000 a year if you’re taking it daily. Similar savings show up with blood pressure meds like lisinopril and cholesterol drugs like simvastatin.According to a 2022 Kaiser Family Foundation report, nearly 15% of Medicare Part D users in the U.S. split pills to cut costs. That number is likely similar in Australia, especially among seniors and those on fixed incomes. The practice is common because drug pricing doesn’t follow logic-it follows profit. A 100mg tablet doesn’t cost twice as much as a 50mg one, even though it contains twice the active ingredient. That’s why splitting works… when it’s done right.
Not All Pills Can Be Split
This is the part most people get wrong. You can’t just split any pill and expect it to work. Some medications are designed to release slowly over hours. If you cut them, you risk dumping the full dose all at once.Never split:
- Extended-release tablets (like metformin ER, Adderall XR, or OxyContin)
- Enteric-coated pills (like omeprazole or aspirin with a shiny coating)
- Capsules or gelcaps
- Medications with a narrow therapeutic index-where even a 5-10% dose change is dangerous
That last group includes warfarin, digoxin, levothyroxine (Synthroid), and tacrolimus. These drugs need to stay in your bloodstream at a very precise level. Splitting them can cause your INR to spike, your heart to race, or your thyroid to go haywire. One Reddit user reported being hospitalized after splitting a time-release amlodipine tablet. Another split their Synthroid and ended up with emergency blood work because their TSH levels went off the charts.
How to Tell If a Pill Can Be Split
Look for a score line-a groove down the middle of the tablet. That’s a clue, but not a guarantee. The FDA says a score doesn’t mean the pill is approved for splitting. You need to check the package insert. If it says “do not crush or split,” don’t do it. If it says “may be split,” you’re probably okay.Here’s the real trick: contact your pharmacist. They have access to the manufacturer’s data and know if the pill has been tested for splitting. Most won’t have the answer on hand, but they can look it up. Ask: “Is this tablet approved for splitting by the FDA?” If they hesitate or say “I’m not sure,” that’s a red flag.
The Only Safe Tool: A Pill Splitter
Never use a knife, scissors, or your teeth. Even a clean kitchen knife can crush the pill or create uneven halves. A dedicated pill splitter costs between $3 and $10 at any pharmacy. It has a V-shaped holder to keep the pill steady and a retractable blade that cuts cleanly down the middle.Studies show using a pill splitter keeps dose variation under 15%. Knife-splitting? That can lead to 72% variation. One 2010 study found that nearly half of volunteers splitting hydrochlorothiazide tablets ended up with doses that were off by more than 10%. That’s not a small error-it’s the difference between effective treatment and dangerous side effects.
Use the splitter every time. Don’t skip it because you’re in a hurry. Wash your hands before handling pills. Clean the splitter after each use with a dry cloth-no water, which can rust the blade. Store the splitter in a dry place.
Split Right Before You Take It
Don’t split a week’s supply and store the halves. Once a tablet is cut, the exposed surface is vulnerable to moisture, heat, and air. Medications like levothyroxine and some antibiotics lose potency quickly. Banner Health’s 2022 guidelines say split tablets should be used within 24-48 hours at most. If you’re not taking the split dose immediately, keep the whole tablet intact.Some people split pills and store them in a pill organizer. That’s a bad idea unless the medication is specifically approved for long-term storage after splitting. Even then, humidity from your bathroom or kitchen can ruin the dose.
Cost Savings Aren’t Always Real
Pill splitting doesn’t save money on every drug. Sometimes, the lower-dose version is cheaper per milligram. For example, sertraline 100mg tablets cost $0.12 each, while 50mg tablets cost $0.08. Splitting the 100mg gives you two 50mg doses for $0.12-same as buying two 50mg pills. No savings. In fact, you’re risking your health for zero benefit.Before you split, check GoodRx or your pharmacy’s price list. Compare the cost per milligram of the higher-dose tablet vs. the lower-dose version. If the math doesn’t add up, don’t split. Use a free price comparison tool. Most Australian pharmacies offer this online.
When Splitting Is a Last Resort
The American Society of Health-System Pharmacists says pill splitting should only be considered if:- The medication isn’t available in your needed dose
- You can’t afford the correct dose
- You’ve tried all other options
Those other options? Patient assistance programs, pharmacy discount cards, generic alternatives, or switching to a different drug in the same class. Many drug makers offer free or low-cost programs for people with low income. In Australia, the PBS Safety Net can reduce your out-of-pocket costs after you hit a certain threshold each year. Talk to your pharmacist about these before you reach for the splitter.
What to Do If You’ve Already Split a Pill
If you’ve split a pill that shouldn’t have been split-like a time-release tablet or a narrow-therapeutic-index drug-stop taking it. Don’t wait for symptoms. Call your doctor or pharmacist immediately. They can advise whether you need a blood test or a change in medication.If you split a pill that’s okay to split but ended up with uneven halves, don’t take the smaller piece. Discard it. Take the larger half only if it’s close to the right dose. But even then, it’s better to call your pharmacist and ask if you should take the full half or wait for a new prescription.
How to Get Started the Safe Way
Follow this five-step process:- Ask your doctor or pharmacist: “Is this pill safe to split?” Get it in writing if possible.
- Check the package insert for instructions on splitting. Look for phrases like “may be split” or “do not crush.”
- Buy a $5 pill splitter from your local pharmacy. Don’t use anything else.
- Split the pill right before you take it. Never pre-split a week’s supply.
- Discard any crumbled, broken, or uneven halves. Don’t try to “fix” them.
It takes 3-5 tries to get good at splitting. Most people are consistent after a week. If you’re struggling, ask your pharmacist to demonstrate. Many offer free training.
Alternatives to Pill Splitting
If you’re worried about safety, there are safer ways to save:- Ask for generics-often 80% cheaper than brand names
- Use a pharmacy discount card (like RxSaver or ScriptSave)
- Apply for patient assistance programs from drug manufacturers
- Check if your PBS eligibility can be adjusted for higher out-of-pocket costs
- Switch to a different medication in the same class that’s available in your needed dose
These options carry no risk of dose inaccuracy. And many save just as much-or more-than splitting.
Final Thought: Safety Over Savings
Pill splitting can be a smart way to save money-but only if you do it correctly. The risks are real. Dose errors from splitting have led to hospitalizations, heart problems, and even deaths. The FDA has documented over 120 adverse events linked to improper splitting between 2018 and 2023.Don’t let cost pressure push you into a dangerous habit. Talk to your pharmacist. Ask questions. Use the right tools. And if you’re unsure, don’t split at all. Your health isn’t worth the gamble.

I’ve been splitting my lisinopril for 3 years now with a $4 splitter from Walmart. Never had an issue. Just make sure it’s scored and you clean the blade after each use. My pharmacist even gave me a sticker that says "FDA-approved for splitting" on my pill bottle. 🙌
bro just use a coin and a knife 😭 i split my metformin like this for 2 years and still alive. no cap.
Using a knife to split pills is not just irresponsible-it’s medically negligent. The FDA has issued multiple warnings about this practice. If you’re cutting pills without a proper splitter, you’re not saving money-you’re gambling with your life. This isn’t a DIY project. It’s pharmacology.
Let’s be real. Pill splitting is a symptom of a broken healthcare system. Drug companies charge $500 for a 30-day supply of a generic that costs $2 to produce. The real villain isn’t the person splitting pills-it’s the executives who raise prices 200% every year. Stop blaming patients. Fix the system.
My grandma splits her simvastatin. Uses the splitter. Never pre-splits. Just says "if it looks weird, don’t take it." Smart lady.
As someone who grew up in South Africa and now lives in the U.S., I’ve seen how absurd drug pricing is. In Cape Town, my dad paid $0.50 for a 40mg atorvastatin tablet. Here? $4.27. Pill splitting isn’t a hack-it’s survival. And honestly? The fact that we even have to do this says everything about how broken this system is.
I started splitting my levothyroxine after reading this post. I called my pharmacist first-they said it was okay but to split it daily and store the whole tablet in the fridge. I also checked GoodRx and found the 100mcg was actually cheaper per mcg than two 50mcg ones. So I switched. No splitting needed. Always check the math first!
They want you to split pills so they can keep selling you the expensive ones. You think this is about safety? Nah. It’s about control. The FDA, Big Pharma, and your doctor all profit when you’re confused. They’ll tell you "don’t split"-but they’ll never tell you why the 40mg costs 20% more than the 20mg. Something’s off. I’m not splitting. I’m just not buying.
Wow. Someone actually wrote a 2,000-word essay on pill splitting. How noble. Meanwhile, people in countries with universal healthcare are laughing at us for treating medicine like a luxury good. You spent more time writing this than you would’ve spent calling your pharmacy to ask for a discount card. Just get a generic. Or move to Canada.
