Side Effects of Benzonatate
Benzonatate is a prescription medication used to relieve coughing by numbing the throat and lungs, reducing the cough reflex. It is often used for conditions like bronchitis or the common cold. While generally considered safe when used correctly, benzonatate can cause various side effects, ranging from mild to severe.
Common Side Effects:
- Drowsiness:
- Drowsiness or sleepiness is one of the most commonly reported side effects. It is important to avoid driving or operating machinery until you know how the medication affects you.
- Dizziness:
- Some individuals experience dizziness or a feeling of being lightheaded after taking benzonatate.
- Headache:
- Headaches can occur, though they are typically mild and resolve on their own.
- Upset Stomach:
- Some users report nausea, vomiting, or stomach upset.
- Constipation:
- Benzonatate may cause constipation in some individuals.
Serious Side Effects:
- Allergic Reactions:
- Although rare, allergic reactions can occur. Symptoms include rash, itching, swelling of the face, lips, or throat, difficulty breathing, or hives. This requires immediate medical attention.
- Mental Confusion or Hallucinations:
- In rare cases, benzonatate can cause mental confusion, visual or auditory hallucinations, and restlessness. These symptoms are more likely to occur at higher doses or with overdose.
- Numbness in the Mouth or Throat:
- Chewing or sucking on benzonatate capsules can lead to numbness of the mouth, tongue, or throat, which may lead to choking or difficulty swallowing. Always swallow the capsule whole to avoid this effect.
- Seizures:
- Overdose or improper use of benzonatate has been linked to seizures, particularly in children and individuals who take more than the recommended dose.
- Cardiac Arrest:
- Overdose can also lead to serious heart issues, including cardiac arrest or arrhythmias.
Special Considerations for Children:
- Accidental Ingestion of benzonatate in children, even in small amounts, can be fatal. Symptoms of overdose in children include restlessness, tremors, seizures, coma, and cardiac arrest. Benzonatate should be kept out of reach of children at all times.
Tips to Minimize Side Effects:
- Take as prescribed: Always swallow the capsules whole without chewing or crushing.
- Avoid overdose: Never take more than the prescribed dose, and store the medication safely away from children.
- Seek immediate medical help if you experience serious side effects like severe allergic reactions, numbness, or confusion.
