Difficulty swallowing can be uncomfortable and sometimes frightening, especially when you are taking medication for anxiety or panic disorders. But can benzodiazepines cause this problem? These medicines can cause side effects such as drowsiness and muscle relaxation, which may affect swallowing in some circumstances. However, swallowing difficulties can also have other causes and should not automatically be blamed on medication.
This article explains warning signs, possible causes, and when to seek medical advice if swallowing problems persist or worsen.
Why Might Benzodiazepines Cause Swallowing Problems?
Benzodiazepines may contribute to swallowing difficulties because they slow activity in the central nervous system and relax muscles. As a result, they may affect the coordination and strength of muscles involved in swallowing. A 2023 case report published in Internal Medicine described possible benzodiazepine-related swallowing problems linked to reduced muscle function and changes in the upper esophageal sphincter.
However, this evidence is limited, and other conditions or medications may also cause difficulty swallowing. If symptoms begin after starting a benzodiazepine or changing your dose, contact your healthcare professional for an assessment.
Which Benzodiazepines Are Associated With Difficulty Swallowing?
Several benzodiazepines may affect swallowing, mainly because they cause drowsiness, reduce alertness, or relax muscles. These include lorazepam (Ativan), diazepam (Valium), alprazolam (Xanax), clonazepam (Klonopin), and temazepam (Restoril). A 1997 case report linked long-term lorazepam use with swallowing difficulty, while a 2023 report described improvement after reducing and discontinuing multiple benzodiazepines under medical care.
- Common medications: Lorazepam, diazepam, alprazolam, clonazepam, and temazepam.
- Possible effects: Drowsiness, reduced coordination, and muscle relaxation.
- Risk factors: Higher doses, other sedatives, and underlying health conditions.
- Warning signs: Coughing, choking, or food sticking in the throat.
- Safety advice: Consult a healthcare professional; never stop benzodiazepines suddenly.
What Other Benzodiazepine Side Effects Can Affect Swallowing?
Benzodiazepines can cause side effects that may interfere with safe swallowing. Drowsiness and reduced alertness can affect coordination between breathing and swallowing. Additionally, muscle relaxation and muscle weakness may reduce the strength of muscles involved in moving food toward the esophagus. Some people may also experience reduced saliva, making food feel harder to swallow. In addition, these medicines may affect esophageal movement or increase the risk of reflux. A 2023 case report discussed these possible mechanisms, although evidence remains limited.
How to Recognize Medication-Related Swallowing Difficulties
Medication-related swallowing problems may begin after you start a new medicine, increase your dose, or combine medicines that cause drowsiness. You may notice coughing or choking while eating, food sticking in your throat, difficulty swallowing pills, or a wet-sounding voice after drinking. Additionally, some people experience drooling or repeated chest infections. However, these symptoms can also result from other medical conditions, so timing alone cannot confirm the cause. Keep track of when symptoms began and tell your healthcare professional about all medicines you take. Seek emergency care if you cannot swallow saliva or have difficulty breathing. Never change or stop prescribed medication without medical guidance.
When Is Difficulty Swallowing a Serious Side Effect?
Difficulty swallowing can become serious when food, liquids, or saliva enter the airway instead of reaching the stomach. Watch for repeated choking, coughing during meals, a wet or gurgling voice, or food getting stuck in your throat. Additionally, painful swallowing, dehydration, or repeated chest infections need prompt medical assessment. Seek emergency care if you cannot breathe, cannot swallow saliva, or experience sudden swallowing difficulty with facial drooping, weakness, or trouble speaking. These signs may indicate a medical emergency rather than a medication side effect. If symptoms begin after taking a benzodiazepine, contact your healthcare professional promptly. Do not adjust your dose or stop suddenly without medical guidance.
How Are Benzodiazepine-Related Swallowing Problems Evaluated and Managed?
A healthcare professional will review your symptoms, medication list, dosage, and when the swallowing difficulty began. Depending on your symptoms, they may examine your swallowing or refer you to a speech-language pathologist for a swallowing assessment. They may also recommend tests to check how food and liquid move through your throat and esophagus. Treatment depends on the cause. For example, your clinician may adjust your medication or recommend swallowing strategies and texture changes. However, never reduce or stop benzodiazepines on your own, because sudden withdrawal can be dangerous. Seek urgent care if you choke repeatedly, cannot swallow saliva, or have trouble breathing.
When Should You Seek Medical Help for Difficulty Swallowing?
Seek medical advice if swallowing becomes difficult after starting a benzodiazepine or changing your dose. Additionally, contact a healthcare professional if you frequently cough during meals, feel food sticking in your throat, experience painful swallowing, or struggle to drink enough fluids. These symptoms may indicate a medication side effect or another medical condition that needs assessment. Seek emergency care if you cannot swallow saliva, choke severely, or have trouble breathing. Sudden swallowing difficulty with facial drooping, weakness, or slurred speech may also signal a stroke. Meanwhile, do not change or stop your benzodiazepine dose without medical guidance, because sudden withdrawal can cause serious complications.
Conclusion
Difficulty swallowing while taking benzodiazepines should never be ignored. Recognizing symptoms early, understanding their severity, and seeking timely medical advice can help prevent complications. Although these medicines may contribute to swallowing problems, other conditions can also cause them. Therefore, a healthcare professional should assess persistent or worsening symptoms. Never stop benzodiazepines suddenly, as abrupt withdrawal can be dangerous. Instead, work with your healthcare provider to plan a gradual, supervised taper. The 2025 ASAM clinical guideline provides evidence-based guidance for safer benzodiazepine management.
