How to Crush Pills Safely and Correctly

Learn which pills can and cannot be crushed

If you have difficulty swallowing pills and there are no liquid or syrup formulations available, crushing pills may be a reasonable option. However, not every pill can be crushed as doing so can affect the absorption and effectiveness of certain medications.

Before crushing a pill, ask your pharmacist or healthcare provider if it is safe to do. If it can be crushed, there is a right way and a wrong way to accomplish this.

This article describes the different ways to crush a pill and lists some of the pills and tablets that should never be crushed.

How to Crush Pills

Many pharmacies place stickers on pill bottles stating they should not be crushed. If you don’t see a warning label, ask your healthcare provider or pharmacist before crushing any pill or tablet.

There are three devices you can use:

  • Pill crusher: Most pill crushers are handheld devices that you twist to grind a pill into a fine powder. Others look like a stapler or garlic press that you grip to crush the pill.
  • Mortar and pestle: A mortar is a cup-shaped bowl and a pestle is a club-shaped tool used to grind the pill manually. While effective, it may be difficult to use if you have arthritis.
  • Pill splitter: This handheld device does not crush pills but can split them into halves or quarters so that they are easier to swallow.

Pills crushed in a pill crusher or a mortar and pestle can be dissolved in a small amount of water or mixed into a small amount of soft food. This ensures you are given the complete dose prescribed by your doctor.

By mixing the crushed pill into a large amount of water or food, you risk losing some of the medication on the plate, bowl, or utensil and may end up being underdosed.

Which Pills Cannot Be Crushed?

Not every pill can be crushed. There are certain pills that are designed to be dispersed in certain parts of the digestive tract or at a specific rate. Crushing certain pills can cause them to be released too early or too quickly, increasing the risk of side effects and/or reducing the absorption and effectiveness of the drug.

There are three types of pills, among others, that should never be crushed:

Enteric-Coated Pills

Enteric-coated drugs are coated to reduce stomach irritation. The coating is gradually dissolved as it passes through the stomach so that the drug begins to be released as it travels to the intestine. Some drugs are also enteric-coated to avoid teeth staining or to prevent stomach acids from destroying the active drug.

For these reasons, enteric-coated pills or tablets should never be crushed, broken, or chewed.

Enteric-coated tablets often have “EN” (enteric) or “EC” (enteric-coated) tagged at the end of their brand names.

Examples include:

How to Recognize Enteric-Coated Pills

You can often tell that a pill is enteric-coated when it has a slight sheen or gloss. If in doubt, ask your pharmacist.

Sustained-Release Drugs

Sustained-release pills are similar to enteric-coated pills in that they are meant to be absorbed slowly. Crushing the pill causes the drug to be released all at once.

By doing so, the concentration of the drug will be high at first and then drop sharply as it is rapidly excreted from the body. This not only reduces the drug’s effectiveness but also increases the risk or severity of side effects.

Sustained-release pills sometimes have the letters “CR” (controlled-release), or “ER,” “XL,” or “XR” (extended-release) in their names.

Examples include:

Opioid Drugs

You should never crush an opioid drug. These drugs, used primarily for pain relief, have a high potential for drug addiction. They are designed to be released at a controlled, steady rate to avoid an unintended “high” and feelings of euphoria that promote addiction.

Crushing an opioid drug may release it too quickly into the bloodstream, increasing the risk of an overdose. However, some opioids now come in abuse-deterrent formulations containing an opioid agonist—a substance that blocks the effects of opioids—that gets mixed with the opioid if the pills are crushed.

Some of the more commonly prescribed opioids include:

What Not to Do

Some people may be tempted to crush their pills by placing them in a plastic bag and hitting them with a hammer or mallet. This is problematic for several reasons:

  • It can create holes in the bag, causing you to lose medication.
  • The powdered medication can collect in the corners of the bag, making it hard to retrieve.
  • Some of the medication can get stuck in the plastic itself.
  • Chunky fragments that remain can get caught in your throat, causing choking.

Chewing pills should also be avoided unless the drug is designed to be chewable. Chewed pills can get stuck in your teeth, reducing the dose, or cause a bitter taste. The crushed pill might also irritate the gums, mouth, esophagus, or stomach if it is released quicker than intended.

Do Not Mix Drugs

It is also not a good idea to mix crushed pills. If you need to crush two or more pills, each should be crushed separately and taken separately.

Other Considerations

You will need to learn which foods you can and cannot mix with crushed medications. Things like applesauce, fruit juice, pudding, yogurt, or water are generally safe, but other foods are known to interact with certain drugs.

For example, grapefruit juice can interfere with how certain drugs are metabolized (broken down) and lower the concentration of the drug in the bloodstream. These include statin drugs, anticoagulants (blood thinners), and calcium channel blockers.

Other drugs need to be taken without food, meaning that you may have to deal with the bitter taste.

If you or your child have difficulty swallowing pills, ask your healthcare provider if there are other formulations available. This may include chewable tablets, gummies, syrups, suspensions, powders, suppositories, and dissolvable sublingual (under the tongue) films, pellets, and wafers.

Summary

Crushing pills may be OK if you or your child have trouble swallowing pills. Still, it’s important to remember that not all medications can be crushed, especially enteric-coated pills, sustained-release pills, and opioid drugs.

If you can crush a pill, use a recommended method like a pill crusher or a mortar and pestle to grind the pill to a fine powder. Ask your healthcare provider or pharmacist how you should take the powdered drug, including which foods or beverages they can be safely mixed with.

If a drug cannot be crushed, ask your healthcare provider if there are other formulations you can take, such as syrups, suspensions, or gummies.
