If you’re reading this article, chances are you or someone you care for is using an enteral tube for medication administration. It’s a common route of drug delivery that’s used when oral medications aren’t feasible or effective. However, certain types of medications can’t be given via an enteral tube due to their chemical properties and the potential risks they pose.
When administering medications through an enteral tube, healthcare providers need to consider factors like drug formulation, pH, absorption rate, and compatibility with feeding formulas. For instance, medications that are enteric-coated or have extended-release formulations may not dissolve or get absorbed properly in the gastrointestinal tract when delivered through a tube. Additionally, certain medications can interact with feeding formulas or cause clogging or blockage in the tube.
So what are some of the types of medications that can’t be given via an enteral tube? Well, the list is quite extensive and includes medication categories like antacids, sedatives, antihistamines, proton pump inhibitors, and many others. While there may be some exceptions or alternative routes of administration for these drugs, it’s essential to work closely with your healthcare team to ensure that you’re getting the right medications in the right way.
Definition of Enteral Tube
An enteral tube is a medical device used to deliver nutrition or medication directly to a person’s stomach or small intestine. It is a flexible tube that is inserted through the mouth or nose and guided down the esophagus to the digestive system. This method of administration is preferred when a person is unable to swallow food or medication due to a medical condition or injury, or when their digestive system is not functioning properly.
There are different types of enteral tubes depending on the location of insertion and the length of time it will be in use. The most common types of enteral tubes include nasogastric, nasojejunal, gastrostomy, and jejunostomy tubes. Nasogastric and nasojejunal tubes are temporary tubes that are inserted through the nose and extend down to the stomach or small intestine. Gastrostomy and jejunostomy tubes are permanent or long-term tubes that are surgically implanted into the stomach or small intestine.
Types of Enteral Tubes
Enteral feeding is the process of delivering nutrients through the gastrointestinal tract via a tube. The enteral tube can be passed through the nose to the stomach or intestines, or surgically inserted through the abdomen. Enteral feeding is used when a patient is unable to take food or medication orally. Here are the different types of enteral tubes:
- Nasogastric Tube (NGT) – this tube goes through the nose and down to the stomach
- Nasoenteric Tube (NET) – this tube goes through the nose and down to the small intestine
- Gastrostomy Tube (G-Tube) – this tube is surgically inserted through the abdomen and directly into the stomach
- Jejunostomy Tube (J-Tube) – this tube is surgically inserted through the abdomen and directly into the small intestine
Medications that Cannot be Given via an Enteral Tube
Not all medications can be given through an enteral tube. Some drugs may not be absorbed properly or may become ineffective due to altered pH levels in the stomach or small intestine. Here are some types of medications that should not be administered through an enteral tube:
1. Enteric-coated Tablets – these tablets are designed to resist the acidic environment of the stomach and dissolve in the small intestine to release the medication. However, the coating can clog the feeding tube and prevent proper absorption.
2. Extended-release Capsules and Tablets – these medications are designed to release the drug slowly over time. However, crushing or opening the capsule can release the entire dose at once, leading to potential toxicity. The efficacy of the medication may also be reduced due to altered absorption and pharmacokinetics.
| Medication Name | Type of Medication | Reason for Incompatibility |
|---|---|---|
| Omeprazole | Proton Pump Inhibitor | Enteric-coated tablet; dissolution in acidic environment of stomach required |
| Warfarin | Anticoagulant | Variable bioavailability and increased bleeding risk due to altered absorption and pharmacokinetics |
| Morphine sulfate | Narcotic Analgesic | Extended-release capsule; alteration of absorption and potential for toxicity |
3. Sublingual Tablets – these tablets are designed to be placed under the tongue to dissolve and rapidly enter the bloodstream. However, administering them through an enteral tube would bypass the absorption process and potentially lead to ineffective treatment.
4. Injectable Medications – these medications are not designed for oral administration and can cause severe adverse reactions if given through a feeding tube. In addition, the viscosity or pH levels of the solution can cause clogging or irritation.
It is important for healthcare providers to be aware of the medications that cannot be given through an enteral tube to avoid potential adverse effects and to optimize patient care.
Importance of Enteral Nutrition
Enteral nutrition is the delivery of nutrients, such as protein, carbohydrate, fat, vitamins, and minerals, through a tube directly into the gastrointestinal tract. This type of nutrition is important for patients who cannot eat or swallow food normally due to illness or medical treatment. It is also administered to patients who require extra nutritional support to maintain or improve their health status.
Enteral nutrition can be given through various methods, such as a nasogastric tube, gastrostomy tube, or jejunostomy tube. Each method is chosen based on the patient’s medical condition, nutrient requirements, and expected duration of enteral feeding.
Medications that Cannot be Given via an Enteral Tube
- Enteric-coated medications: These drugs have a special coating that prevents them from dissolving in the stomach and instead dissolve in the small intestine. When given via an enteral tube, the coating may not dissolve properly, resulting in ineffective medication delivery or potential harm to the patient.
- Extended-release or sustained-release medications: These drugs are designed to release the active ingredient slowly over time. Crushing or breaking them may cause the medication to be released too quickly, which may lead to adverse effects or reduced effectiveness.
- Sublingual or buccal medications: These drugs are placed under the tongue or in the cheek to dissolve or absorb quickly. They are not designed to be swallowed and will not be absorbed properly when given via an enteral tube.
Considerations for Medication Administration via Enteral Tube
When administering medications via an enteral tube, healthcare providers should consider several important factors to ensure optimal safety and efficacy.
First, the medication should be in a liquid or soluble form that can easily pass through the tube. If the medication is not readily available in this form, it may need to be crushed and mixed with water or another appropriate solution.
Second, if the medication is known to interact with food or other medications, it should be given separately from the enteral formula or other medications. This can help to avoid potential drug interactions or decreased effectiveness of one or both medications.
Third, the placement and function of the enteral tube should be confirmed before administering any medication. Inappropriate tube placement or malfunction can lead to the medication being delivered to the wrong location or not at all.
| Medication Type | Administration Considerations |
|---|---|
| Liquid or Soluble Medications | May be administered directly through the enteral tube |
| Capsule or Tablet Medications | May need to be crushed and mixed with water or another appropriate solution |
| Enteric-Coated Medications | Not recommended due to potential harm to patient or reduced effectiveness |
| Extended-Release or Sustained-Release Medications | Not recommended due to potential harm to patient or reduced effectiveness |
| Sublingual or Buccal Medications | Not recommended due to lack of absorption via the gastrointestinal tract |
Overall, the administration of medications via an enteral tube requires careful consideration and attention to ensure safe and effective treatment. Healthcare providers should be knowledgeable about the appropriate medications and administration methods for enteral feeding to optimize patient outcomes.
Medications Considered Safe for Enteral Administration
Administering medication through an enteral tube reduces the need for multiple injections, thus improving comfort and compliance. It also facilitates a better-quality infusion of medicines that might have an irritating effect on the mucosa of the stomach or intestine. However, not all medicines are compatible with enteral feeding tubes. Certain preparations can cause clogging, occlusion, or changes in absorption rates. Understanding the types of medications safe for enteral administration can help providers reduce risk and ensure optimal medication delivery.
- Liquid medication: Liquid oral medications are the most commonly used formulations for enteral administration. They flow easily through the tube and can be combined with enteral feeds without causing any blockages.
- Suspensions: Suspensions are a mixture of a solid and a liquid with a particle size sufficiently small to pass through the tube. These medications must be thoroughly shaken before use to ensure uniform dispersion.
- Capsules: Capsules are generally not compatible with enteral feeding. However, some capsules can be opened and the medication inside can be dissolved in water or mixed with food to be delivered through the tube.
Tablets are generally avoided because they have a high risk of causing blockages or partial obstructions in the tube. However, recent advances in formulation technology have led to the creation of tablets designed specifically for enteral administration.
| Medication Type | Considered safe for enteral administration | Precautions/Contraindications for enteral administration |
|---|---|---|
| Liquid medication | Yes | None |
| Suspensions | Yes | Must be shaken before use to avoid clogging tube |
| Capsules | Some can be opened and medication inside dissolved in water or mixed with food. Others not suitable for enteral feeding | Avoid non-crushable capsules, capsules with enteric coatings, or sustained-release formulations |
| Tablets | Depends on formulation, some newer formulations safe for enteral administration. | Avoid tablets that cannot be crushed or dissolve poorly in liquids |
Important note: Providers should always verify medication compatibility before administration. Incomplete or inaccurate information can create serious health risks for patients, particularly in critical care settings.
Medications that Cannot be Crushed or Chewed for Enteral Administration
When administering medications via an enteral tube, it is crucial to know which medications cannot be crushed or chewed before administration. Some medications are designed to be taken whole, and crushing or chewing them can have severe consequences for patients. Here’s a detailed list of medications that cannot be crushed or chewed for enteral administration.
- Aprepitant capsules: Aprepitant capsules should be swallowed whole and not crushed or chewed. Crushing or chewing these capsules can cause irritation in the mouth or throat and lead to difficulty in swallowing.
- Aspirin: Aspirin tablets should not be crushed or chewed because it can lead to irritation in the mouth and throat and cause ulcers or bleeding in the gastrointestinal tract.
- Enteric-coated or Delayed-release tablets: These tablets have a special coating designed to release the medication slowly over time. Crushing or chewing these tablets can cause the medication to be absorbed too quickly, leading to adverse effects or reduced effectiveness.
- Warfarin tablets: Warfarin tablets should be taken whole to ensure they are properly absorbed by the body. Crushing or chewing these tablets can interfere with the absorption process and reduce their effectiveness.
- Sublingual tablets: Sublingual tablets are designed to be placed under the tongue and absorbed directly into the bloodstream. Crushing or chewing sublingual tablets can lead to the medication being absorbed too quickly or not at all.
Why Can’t These Medications be Crushed or Chewed?
The medications listed above cannot be crushed or chewed because such actions can alter their chemical composition, leading to undesirable effects or reducing their effectiveness. Crushing or chewing these tablets can also lead to irritation in the mouth or throat, which can cause inflammation and discomfort.
In some cases, certain medications are designed to be released slowly into the bloodstream, and crushing or chewing them can interfere with this process. This interference can cause the medication to be absorbed too quickly or not at all.
If a patient has difficulty swallowing medications, there are alternatives available, like liquid or injectable versions of the medication. Always speak to your healthcare provider to determine the best course of action before administering any medication via an enteral tube.
| Medication | Reason for Not Crushing/Chewing |

Risks of Improper Medication Administration via Enteral Tube
Administering medications through enteral tubes can help ease delivery and ensure that the medication reaches its destination. Despite this, it’s vital to remember that not all medications are fit to be administered through enteric feeding tubes. Oral medications are typically designed to be taken orally in whole, chewed, or crushed form. When medications not made for tube feeding are crushed or broken down into small pieces or liquid forms, it causes a host of risks.
- The medication is not distributed appropriately in the intestinal tract and cause blockages or even cause complications such as aspiration.
- The medication’s formulation can change, affecting its performance and safety. For example, some time-released extended-release medications may become very concentrated and cause toxicity instead of providing the required treatment dose.
- Potential tube occlusion or even physical damage to the feeding tube. Even medications that already crushed into fine particles, may block the tube’s small bore due to its stickiness, leading to the need for an unanticipated tube replacement. Additionally, if the medication is acidic or alkaline, it may speed up the device’s wear and tear, which means frequent replacements and cost.
Types of Drugs Prohibited to Administer via Enteral Tube
A comprehensive list of medications that should not be administered through the enteral feeding tube is often available in the drug’s prescribing information. The list includes the following medication types:
- Medications that are meant to be taken via inhalation or injection. Examples include asthma inhalers, large protein-based molecules, vaccines, and injectable insulin. Such medications are formulated to be absorbed quickly into the bloodstream by bypassing the digestive system and lungs or processing by the liver. Infusing them through an enteral tube would prevent their function and at best, be a waste of medication delivery.
- Time-release medications that are not made to be crushed or split because the dosage form is designed to achieve a specific time course of action. By disrupting the medication delivery system, the medication will be poorly absorbed or quickly flushed out, leading to uncontrolled therapeutic or severe adverse effects.
- Capsules with an enteric coating or delayed-release. Such coating delays the medication’s breakdown until it reaches the small intestine and prevents the drug from breaking down in the stomach. Crushing these medications would lead to a dose dump locally in the feeding tube and probably cause irritation, pain, and adverse gastrointestinal effects.
- Medications that require mixing or dissolving. These include medications that come as effervescent tablets, hard shell capsules with powders, or granules that require dissolving in water for administration. It’s risky to mix the medications with enteral formula directly, as the foam may form and obstruct the tube, leading to the patient potentially receiving only a partial dose of the dose and an inadequate therapeutic response.
Conclusion
Administering medication through enteral feeding tubes requires skill and knowledge. Knowing what medications cannot be given via this route can prevent complications, side effects, and even life-threatening risks to the patient. Checking with medication drug information, manufacturer recommendations, or consulting with a pharmacist or physician is essential before administering any medications via an enteral tube. It is better to be cautious and confirm if a medication is suitable for enteral delivery than suffer the consequences of not asking the right questions.
| Types of Medications Prohibited to Administer via Enteral Tube |
|---|
| Medications that are meant to be taken via inhalation or injection. |
| Capsules with an enteric coating or delayed-release. |
| Time-release medications that are not designed to be crushed or split. |
| Medications that require mixing or dissolving. |
Protect the positive outcomes of medication therapy through enteral feeding by ensuring monitoring, verifying medication compatibility status, and appropriately administering medications with good tube flushing protocols.
Alternative Medication Administration Routes for Enteral Feeding Patients
Patients who are unable to take medication orally due to an enteral feeding tube may have limited options for medication administration. However, there are alternative routes of medication administration that can be used in these cases.
- Inhalation: Some medications can be administered through inhalation, which delivers the medication directly to the lungs. This method is commonly used for respiratory-related medications like bronchodilators.
- Intramuscular (IM): In some cases, medications can be given through an intramuscular injection. This route may be used for medications that are not absorbed through the digestive system.
- Subcutaneous (SQ): Another alternative to oral medication is subcutaneous injection. Medications are injected under the skin and absorbed slowly into the bloodstream.
It’s important to note that not all medications can be administered through these alternative routes. In addition, these methods may not be appropriate for all patients or all types of medication. A healthcare professional should always be consulted to determine the most appropriate method of medication administration for each individual patient.
Here is a table listing some common medications that cannot be given via an enteral tube and alternative administration routes that may be used:
| Medication | Reason tube feeding cannot be used | Alternative administration route |
|---|---|---|
| Diltiazem extended release (Cardizem CD) | Enteral absorption is altered | Immediate-release diltiazem (oral), Intravenous (IV) |
| Warfarin | Provides inconsistent absorption | Oral, Subcutaneous (SQ), Intramuscular (IM) |
| Phenytoin (Dilantin) | Enteral feeding may decrease absorption | Intravenous (IV) |
| Fluoxetine (Prozac) | Enteral feeding may alter absorption or release rate | Oral solution, Sublingual, Intramuscular (IM) |
Keep in mind that this is not an exhaustive list and that different medications may have different considerations. Patients and caregivers should always consult with a healthcare professional before administering any medication.
