Schedule an appointment immediately if you experience any of the following:
- Severe allergic reactions: These include difficulty breathing, swelling of your face, lips, tongue, or throat, or hives. Chest pain or irregular heartbeat: Propranolol can affect your heart rate and rhythm; report any unusual changes. Severe dizziness or fainting: These symptoms suggest a potential drop in blood pressure. Cold extremities (hands and feet): This can be a sign of poor circulation. New or worsening depression or suicidal thoughts: Propranolol, like other medications, may affect mood in some individuals. Persistent nausea or vomiting: Intense gastrointestinal distress may require attention. Vision changes: Blurred vision or other visual disturbances should be reported.
Contact your doctor promptly if you notice:
Medication ineffectiveness: Your anxiety doesn’t improve or worsens after several weeks on Propranolol. Unwanted side effects that persist: Many mild side effects resolve, but persistent or bothersome ones need evaluation. Medication interactions: Inform your doctor about all medications, supplements, and herbal remedies you’re taking. Propranolol can interact with others. Changes in your health status: Any significant health changes, even unrelated to anxiety, should be discussed with your doctor before continuing Propranolol. Pregnancy or plans to become pregnant: Discuss Propranolol use during pregnancy with your doctor immediately.
Regular checkups are crucial to monitor your response to Propranolol and adjust the dosage as needed. Don’t hesitate to seek medical advice if you have any concerns.
