Hello: The combination of traditional Chinese medicine and Western medicine has shown some promising effects in clinical practice, but it also brings about certain issues.
For instance, in our hospital, the use of betel nut in conjunction with Flupenthizol (Fluanxol) may lead to symptoms such as rigidity and jaw tremors.
Additionally, combining ginseng, a tonic, with Phenelzine may trigger headaches, tremors, and seizures.
If ginseng is taken simultaneously with alcohol, it may increase the clearance rate of ethanol.

Moreover, St.
John's Wort, a popular herbal supplement for calming and sleep in Europe and America, can cause moderate serotonin syndrome, drowsiness/delirium, and incoherence when used with antidepressants like Paroxetine, Trazodone, and Sertraline.
Generally, any medication that acts on the central nervous system, whether traditional or Western, can have interactions.
Furthermore, combining cardiotonics, anticoagulants, or antidiabetic medications with traditional Chinese medicine can lead to severe adverse reactions.
It is advisable to discuss the benefits and risks with your physician or pharmacist.
Regarding the timing of taking these medications, it is recommended to space them 2-4 hours apart.
Each medication has its specific formulation (tablets, liquids, injections, etc.), which is designed and tested by pharmaceutical companies to ensure ease of use and precise dosing for therapeutic effects.
Generally, except in special circumstances (such as infants, individuals who cannot swallow, or those receiving tube feeding), it is not recommended to alter the formulation of medications, as this may affect their efficacy and stability.

Specifically, long-acting tablets, enteric-coated tablets, special formulations (soft capsules), hygroscopic medications, and those requiring protection from light should not be crushed.
Currently, medications in our hospital that should not be crushed include Sustained Release Tablets, Kangdian Neng (soft capsules), Diba Dian (hygroscopic), Jin Pusa (light-sensitive), and Enteric-Coated Tablets (acting in the small intestine), among others.

With advancements in the pharmaceutical and biotechnology industries, more new formulations are being developed, some of which require administration only once a month to achieve therapeutic effects.
Pharmaceutical companies are primarily focused on creating convenient dosing methods, effectively targeting treatment sites, and minimizing side effects.
However, in situations where alternatives are not readily available, if there is a special need to crush medications, it is essential to consult your pharmacist or physician to consider alternative formulations.
Wishing you good health.

More Info


When it comes to medication management, particularly for patients who may have difficulty swallowing pills or who are looking for alternatives to traditional oral administration, it is crucial to understand which medications should never be crushed. Crushing certain medications can lead to serious health risks, including altered effectiveness, increased side effects, or even toxicity. Here’s a comprehensive guide on this topic.


Medications That Should Never Be Crushed
1. Extended-Release and Sustained-Release Formulations: Medications designed to release their active ingredients slowly over time should never be crushed. Examples include:
- OxyContin (oxycodone): Crushing this medication can lead to a rapid release of the drug, increasing the risk of overdose.

- Adderall XR (amphetamine): Crushing can lead to a sudden spike in the drug's effects, which can be dangerous.

2. Enteric-Coated Medications: These are coated to prevent them from dissolving in the stomach, allowing them to reach the intestines where they can be absorbed. Crushing these can lead to stomach irritation or reduced effectiveness. Examples include:
- Ecotrin (enteric-coated aspirin): Crushing can cause gastrointestinal side effects.

3. Hormonal Medications: Some hormonal medications, such as certain forms of estrogen or testosterone, should not be crushed as it can alter their absorption and effectiveness.

4. Certain Antibiotics: Medications like Augmentin (amoxicillin/clavulanate) should not be crushed as it can affect the stability of the drug.

5. Medications with a Narrow Therapeutic Index: Drugs that require precise dosing, such as warfarin or digoxin, should not be crushed because even small changes in dosage can lead to serious health consequences.

6. Liquid Formulations: Some medications are available in liquid form and should be taken as such. Crushing solid forms of these medications can lead to incorrect dosing.


Guidelines for Taking Medications
1. Timing Between Doses: When taking multiple medications, it is essential to consult with a healthcare provider or pharmacist about the appropriate timing between doses. Some medications may require spacing to avoid interactions or to ensure optimal absorption. For example, antacids should generally be taken at least two hours apart from other medications.

2. Drug Interactions: Certain medications should not be taken together due to potential interactions that can either enhance side effects or reduce effectiveness. For instance:
- Antibiotics and Antacids: Antacids can interfere with the absorption of certain antibiotics, such as tetracyclines and fluoroquinolones.

- Blood Thinners and NSAIDs: Taking non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen with blood thinners can increase the risk of bleeding.


Recommendations for Patients
- Consult Your Pharmacist or Doctor: Always discuss with your healthcare provider or pharmacist before making any changes to how you take your medications. They can provide guidance on which medications can be safely crushed or if there are alternative formulations available.


- Use Pill Splitters or Crushers: If you have medications that can be safely crushed, using a pill splitter or crusher can help ensure you are taking the correct dose. However, always confirm that the specific medication is safe to crush.

- Consider Liquid Alternatives: If swallowing pills is a challenge, ask your healthcare provider if liquid formulations are available for your medications.

- Monitor for Side Effects: If you experience any unusual symptoms after changing how you take your medications, contact your healthcare provider immediately.

In summary, understanding which medications should never be crushed is vital for ensuring safe and effective treatment. Always consult with healthcare professionals regarding the best practices for medication management, especially when dealing with complex regimens or specific health conditions.
