To crush a pill safely, place it in a pill crusher, plastic bag, or mortar and pestle and grind it into a fine, even powder. But before you crush anything, you need to confirm the pill is safe to crush, because certain tablets can cause serious harm when their structure is broken. Here’s how to do it right.
Check Whether Your Pill Is Safe to Crush
Not every tablet can be crushed. Extended-release, sustained-release, and enteric-coated pills are specifically engineered to control how and where the drug enters your body. Crushing them destroys that design, potentially releasing hours’ worth of medication all at once. This is called “dose dumping,” and depending on the drug, it can cause dangerous spikes in blood levels, overdose symptoms, or severe stomach irritation.
Look at your pill’s name on the label. Common suffixes and prefixes that signal a pill should never be crushed include: ER, XR, XL, SR, CR, LA, CD, CC, SA, TR, TD, EC, EN, and phrases like “12-hour” or “24-hour.” These all indicate some form of controlled or delayed release. If you see any of these, do not crush the pill without first speaking to your pharmacist about a safe alternative, such as a liquid formulation.
Enteric-coated tablets (often marked EC or EN) have a protective layer that keeps the drug intact through the stomach so it can be absorbed in the small intestine. Crushing removes that protection. The drug may be destroyed by stomach acid before it works, or it may irritate your stomach lining.
Sublingual tablets, designed to dissolve under the tongue, are another category to avoid crushing and swallowing. These drugs are formulated to absorb directly through the tissue in your mouth, bypassing the digestive system entirely. Swallowing them in crushed form may reduce or eliminate their effectiveness.
Tools for Crushing Pills
You have several options, and they vary in how much medication they actually deliver. A study testing 24 different crushing devices found that drug loss ranged from 1.9% to 13.7% depending on the device. Only about half the devices tested recovered at least 95% of the drug. That means your choice of tool matters, especially for medications where precise dosing is important.
The most common options:
- Twist-top pill crushers: These are the small plastic devices you’ll find at most pharmacies. You place the pill in a small cup, twist the top, and the pill is ground into powder. They’re convenient and inexpensive, but models with serrated grinding surfaces tend to trap more powder in the grooves, increasing drug loss.
- Mortar and pestle: Effective for producing a fine powder, but harder to clean thoroughly between medications. If you take multiple drugs, residue from one pill can contaminate the next.
- Plastic bag method: Place the pill in a small sealed bag and press it with the back of a spoon or a rolling pin. This minimizes loss because you can cut the bag open and scrape out nearly all the powder. Some commercial crushers use disposable pouches or cups for the same reason.
- Electronic crushers: These work on the same principle as manual crushers but use a button-activated mechanism. They’re helpful if you have limited hand strength or arthritis.
Whichever tool you use, look for powder stuck in crevices and try to recover as much as possible. Rinsing the crusher with a small amount of water and drinking the rinse is one way to capture leftover medication.
How to Mix Crushed Pills
Crushed medication often tastes bitter, so mixing it into a small amount of soft food makes it much easier to swallow. Good options include applesauce, yogurt, pudding (chocolate or lemon), jam, ice cream, or a flavored syrup like chocolate or strawberry. You can also stir crushed pills into a small amount of juice.
A few rules to follow: use only a small spoonful of food so you can finish all of it in one or two bites. If you leave some behind, you’re leaving some of your dose behind. Never bake medication into food, because heat can break down the active drug. And crush the pill right before you take it. Letting crushed medication sit, especially mixed into food or liquid, can affect stability. Some drugs begin degrading once exposed to air, moisture, or the acidity of certain foods.
If you’re giving crushed medication to a child, let them choose which food to mix it with. Getting buy-in on the taste makes the whole process smoother.
Crushing Pills for a Feeding Tube
If you’re administering crushed medication through a nasogastric or gastric feeding tube, the process requires more precision. Crush the pill into a fine powder, then suspend it in water. The tube should be flushed with 15 to 30 mL of water before and after administration to prevent clogging and ensure the full dose reaches the stomach.
If you need to give multiple medications through a tube, administer them one at a time. Flush with 5 to 10 mL of water between each drug. Mixing crushed medications together in a single solution creates unpredictable interactions and stability problems. Some drugs should be followed immediately by enteral feeding to ensure proper absorption.
Reducing Drug Loss and Contamination
The biggest practical concerns when crushing pills at home are losing medication in the device and cross-contaminating between drugs. To minimize both:
- Use disposable pouches or bags when available. They capture more powder and eliminate the risk of residue from a previous pill.
- Clean reusable crushers thoroughly between medications. Warm water and a small brush work well for getting powder out of grooves.
- Crush one medication at a time. Combining pills before crushing makes it impossible to separate them if something goes wrong.
- Administer immediately after crushing. The longer crushed powder sits exposed, the more it can absorb moisture or degrade.
For people who handle medications professionally or crush pills for others regularly, some drugs are classified as hazardous and can pose risks through skin contact or inhalation of dust during crushing. Certain chemotherapy drugs and hormonal medications fall into this category. If you’re a caregiver crushing pills for someone else and you’re unsure whether a medication requires protective gloves or a mask, your pharmacist can check whether it appears on the NIOSH hazardous drug list.
When a Liquid Form Is the Better Option
If you or someone you care for has difficulty swallowing pills regularly, crushing every dose gets tedious and introduces room for error. Many common medications are available in liquid, chewable, or orally disintegrating tablet forms. These alternatives eliminate the guesswork around drug loss, stability, and whether a particular pill is safe to crush. Your pharmacist can check whether a liquid version of your medication exists, and in some cases a compounding pharmacy can prepare one.
