Direct Answer: Can Benzonatate Make You High?
No. At standard prescribed doses, benzonatate is not used to produce euphoria or a "high." It is a non-opioid cough suppressant that acts locally on stretch receptors in the lungs and airways. While it is possible to experience unintended side effects or misuse it in ways that change perception, this is not its intended effect and is considered dangerous rather than recreational.
Understanding how benzonatate works, why it is prescribed, and the real risks of misuse helps clarify the difference between therapeutic use and hazardous misuse. This article explains the mechanism, legitimate side effects, safety concerns, and why some substances are misused despite not being effective or safe as intoxicants.
What Benzonatate Is and Why It Is Prescribed
Benzonatate is a non-opioid antitussive (cough suppressant) sold under brand names such as Tessalon. It is used to relieve dry, irritating coughs by reducing the cough reflex in the lungs and airways. It is not an opioid, stimulant, or psychedelic, and it is not controlled as a drug of abuse in most jurisdictions.
Because it is not psychoactive at recommended doses, it has low abuse potential compared with medications that affect the central nervous system. However, in very large amounts it can produce serious, dangerous effects, which sometimes leads to curiosity or misuse.
Key Prescribed Uses
- Relief of dry, nonproductive cough associated with respiratory conditions.
- Adjunct therapy when cough control is needed for comfort or healing.
- Short-term symptom management rather than a long-term treatment.
How Benzonatate Works (Mechanism of Action)
Benzonatate acts as a local anesthetic on the cough receptors located in the lungs and the lining of the airways. It numbs these stretch receptors, which reduces the irritation that triggers the cough reflex. This action is largely peripheral and does not produce systemic central nervous system depression or euphoria at normal doses.
Because it does not significantly cross into the brain in therapeutic amounts, it does not affect mood, perception, or consciousness in the way that drugs capable of producing a "high" do.
Comparison With Other Cough Medications
| Medication | Type | Potential for Euphoria at Standard Doses | Typical Duration |
|---|---|---|---|
| Benzonatate | Non-opioid, local anesthetic | None to minimal | 3–8 hours |
| Dextromethorphan (DXM) | Opioid derivative (acting on sigma/k receptors) | Possible at very high doses (risk of adverse effects) | 3–6 hours |
| Diphenhydramine | Antihistamine | Mild, with anticholinergic effects at high doses | 4–6 hours |
Reported Experiences and Why They Are Not a "High"
Some people report sensations such as mild dizziness, lightheadedness, or a brief feeling of disorientation after taking benzonatate, especially if they swallow the capsule whole rather than as intended, or if they take more than the prescribed dose. These sensations are due to local anesthetic effects and are not comparable to the euphoric or intoxicating effects produced by other substances.
True intoxication involves changes in mental state, perception, and behavior, which benzonatate does not reliably produce at medically supervised doses. Any pleasurable sensations are typically mild, short-lived, and accompanied by risks such as choking, respiratory depression, or overdose.
Risks and Dangers of Misusing Benzonatate
Taking higher-than-recommended doses of benzonatate can lead to significant and potentially life-threatening adverse effects. Because it acts as a local anesthetic, large amounts can affect swallowing, breathing, and heart function. Combining it with other central nervous system depressants, such as alcohol or sedatives, can dangerously slow breathing.
Recognized Adverse Effects
- Dizziness or lightheadedness.
- Nausea, vomiting, or stomach discomfort.
- Confusion or disorientation, especially in older adults.
- Seizures in cases of overdose.
- Respiratory depression or difficulty breathing.
- Cardiac arrhythmias or low blood pressure.
These effects underscore why benzonatate should only be used exactly as prescribed and never in pursuit of euphoria.
Who Is at Higher Risk and How to Use Safely
Certain groups are more vulnerable to adverse effects from benzonatate, including older adults, people with respiratory or swallowing disorders, and those taking other depressant medications. Intentional misuse—often by crushing capsules to snort or chew—increases the risk of choking, coughing, and rapid onset of toxicity.
Safe use practices include:
- Following the exact dosing instructions provided by a clinician.
- Swallowing the capsule whole with water, without crushing or chewing.
- Avoiding concurrent use of alcohol or other CNS depressants.
- Storing medication securely to prevent accidental or intentional ingestion by others.
When to Seek Medical Help
If someone has taken more benzonatate than prescribed, is experiencing difficulty breathing, extreme drowsiness, confusion, or loss of consciousness, seek emergency medical care immediately. For ongoing concerns about use, talking with a healthcare provider or a poison control center can provide guidance specific to the situation.
Comparing Benzonatate With Other Substances and Clinical Bottom Line
Benzonatate is not an intoxicant and should not be viewed as a substitute for other drugs that people use to achieve a high. Its primary value is as a short-term cough suppressant when used correctly. While some may mistakenly believe its numbing effects could be pleasurable, the reality is that misuse poses serious health risks without providing the desired psychoactive effect.
Clinically, it is safer and more effective for cough control than attempts to use it for intoxication. Anyone struggling with substance use or curiosity about drug effects should consult a healthcare professional for accurate information and support.
