Verapamil, while potentially helpful for Peyronie’s disease, carries side effects. Headaches are common, often mild, but can be bothersome. Dizziness and lightheadedness are also possibilities, so take caution when changing positions quickly.
Heart rate changes are a concern. Verapamil slows the heart rate; this effect can be pronounced in those with pre-existing heart conditions. Consult your doctor about your heart health before starting treatment. Low blood pressure is another potential consequence, potentially leading to fatigue or fainting.
Gastrointestinal issues, such as nausea, constipation, and abdominal pain, can occur. These effects usually are mild, but you should report persistent or severe symptoms to your physician. Swelling in the ankles or legs (peripheral edema) is another possibility.
Rare but serious side effects include heart block and liver problems. Immediate medical attention is necessary if you experience chest pain, irregular heartbeat, or jaundice (yellowing of the skin or eyes). Always inform your doctor of any new or worsening symptoms while on verapamil.
The specific risks and side effects vary depending on factors such as dosage, individual health conditions, and potential drug interactions. Open communication with your doctor is paramount to manage any side effects effectively and safely. Regular monitoring of your health is recommended during treatment.
