Cough Suppression
- Common Cold and Flu: Benzonatate helps reduce coughs associated with colds and flu, providing relief from persistent coughing.
- Respiratory Infections: It’s effective in easing coughs due to respiratory infections like pneumonia and bronchitis.
Off-Label Uses
- While primarily used for cough, some physicians may prescribe Benzonatate for off-label uses, such as certain neurological or gastrointestinal conditions, where its numbing effect can be beneficial.
How It Works
Benzonatate operates uniquely compared to other cough suppressants. Its primary mechanism involves anesthetizing or numbing the stretch receptors located in the lungs and the airways, specifically the pleura and alveoli.
Numbing Effect
When consumed, Benzonatate acts like a local anesthetic. It reduces the sensitivity of the cough receptors in the respiratory tract. This numbing effect decreases the cough reflex, which is triggered by irritation in these areas. This action is similar to how local anesthetics work to numb specific parts of the body.
Impact on Cough Reflex
By dulling the sensitivity of these receptors, Benzonatate effectively reduces the frequency and intensity of coughs. However, it’s important to understand that it doesn’t treat the root cause of the cough, such as an infection or chronic condition. Instead, it provides symptomatic relief by suppressing the cough reflex, making it easier for patients to manage their condition, especially when rest and recovery are needed.

Common Side Effects
Benzonatate is generally well-tolerated, but it can cause some mild to moderate side effects, including:
- Drowsiness: A common side effect, which may affect the ability to drive or operate machinery.
- Dizziness: May occur, especially when rising quickly from a sitting or lying position.
- Headache: Some users report mild to moderate headaches.
- Stomach Upset: Includes symptoms like nausea, constipation, or mild abdominal pain.
- Mild Skin Rash: Rare but possible, often indicating a mild allergic reaction.
Serious Side Effects
Although rare, Benzonatate can cause serious side effects that require immediate medical attention:
- Severe Allergic Reactions: Symptoms include itching, rash, severe dizziness, trouble breathing, or swelling of the face, tongue, or throat.
- Mental/Mood Changes: Includes confusion, hallucinations, or restlessness.
- Breathing Difficulties: Shortness of breath or a feeling of tightness in the chest.
Choking or Severe Throat Pain: Especially if the capsule bursts in the mouth. It should be swallowed whole, not chewed or dissolved.
Patients with a history of allergic reactions to anesthetic drugs should exercise caution. Benzonatate should not be used in children under ten years due to the risk of severe side effects, including choking or breathing problems. Overdosing can be particularly dangerous, leading to convulsions or death.
enzonatate, a non-narcotic cough suppressant, has several potential drug interactions. Here are the key ones categorized under subheadings:
Central Nervous System Depressants:
Interaction: Benzonatate can enhance the sedative effects of other CNS depressants like alcohol, benzodiazepines, opioids, and certain antihistamines.
Management: Patients should be advised to avoid or limit the use of alcohol and other CNS depressants while taking benzonatate.
Antidepressants (MAO Inhibitors and SSRIs):
Interaction: Concomitant use of MAO inhibitors or SSRIs with benzonatate can increase the risk of serotonin syndrome, a potentially life-threatening condition.
Management: Close monitoring is required, and alternative cough suppressants may be considered.
Anticholinergic Drugs:
Interaction: Combined use with anticholinergic drugs (like some antihistamines, tricyclic antidepressants) may increase the risk of certain side effects like dry mouth and urinary retention.
Management: Monitoring for anticholinergic side effects and dose adjustment might be necessary.
Antihypertensive Medications:
Interaction: There might be a potential interaction with antihypertensive drugs, although the risk is unclear.
Management: Blood pressure should be monitored, and adjustments to antihypertensive medications may be needed.
Herbal Supplements:
Interaction: Some herbal supplements (like St. John’s Wort) can interact with benzonatate, affecting its efficacy.
Management: Patients should inform their healthcare provider about any herbal supplements they are taking.
It’s important to consult a healthcare provider for personalized advice and to review all medications and supplements being taken with benzonatate.
The dosage of Benzonatate, used to suppress cough, should be tailored to individual needs but follows general guidelines:
Adults and Children 10 Years and Older:
- Standard dose: 100 mg to 200 mg, up to three times a day as needed.
- Maximum dose: Should not exceed 600 mg per day.
Children Under 10 Years:
Benzonatate is not recommended for use in children under 10 years due to the risk of severe side effects, including choking or suffocation.
Duration of Treatment:
The duration of treatment depends on the cause of the cough and should be as per the doctor’s advice. If symptoms do not improve within a week or if they worsen, medical advice should be sought.
Benzonatate is available only by prescription. This requirement ensures that a healthcare provider evaluates the patient’s condition and determines whether Benzonatate is an appropriate treatment. The prescription-only status also helps in monitoring the patient’s health and adjusting dosages as necessary.
