Benzonatate is a medication prescribed for cough relief. Like all medications, it can cause side effects. A common concern is its potential influence on the digestive system. Many wonder if it can cause issues like diarrhea.
What is Benzonatate
Benzonatate is a non-narcotic cough suppressant. It works by numbing specific stretch receptors located in the lungs and airways. This action helps to inhibit the cough reflex at its source. The medication typically begins to exert its effects within 15 to 20 minutes after oral administration. Its cough-suppressing action then usually lasts for approximately three to eight hours. Benzonatate is available in various oral capsule strengths, including 100 mg, 150 mg, and 200 mg.
Potential Digestive Side Effects
When considering benzonatate, individuals often inquire about its digestive impact. While not as commonly reported as some other digestive issues, diarrhea can occur as part of a general gastrointestinal upset. More frequently, users may experience other digestive complaints such as nausea, constipation, or an upset stomach. Abdominal discomfort or cramps have also been noted.
Most digestive side effects are typically mild and temporary. Their exact frequency is not precisely known, as individual responses vary considerably. Medications can influence the digestive system through various pathways, and while a specific detailed mechanism for benzonatate’s effect on the gut is not widely elaborated, general gastrointestinal upset is a recognized possibility with many drugs.
When to Consult a Doctor
Be aware of symptoms that warrant medical attention while taking benzonatate. If digestive issues, including diarrhea, become severe or persistent, or are accompanied by a fever, chills, or intense abdominal pain, seeking medical advice is recommended. Signs of dehydration, such as reduced urination or excessive thirst, also indicate a need for evaluation.
Immediate medical attention is necessary for allergic reactions, including rash, itching, swelling of the face, lips, tongue, or throat, or difficulty breathing. Other serious symptoms requiring prompt consultation include severe drowsiness or dizziness, confusion, and hallucinations. If a cough does not improve after seven days, or if accompanied by a high fever or persistent headache, discuss these symptoms with a doctor. Always discuss any side effects with a healthcare professional and avoid adjusting dosage without their guidance.
