What is a common side effect associated with Diltiazem?

Diltiazem is a calcium channel blocker commonly used to manage hypertension and certain types of angina, and it is known to have several potential side effects. Among these, oedema, or swelling due to fluid retention, is one of the more prevalent effects. This occurs because the medication can cause peripheral vasodilation, which can lead to increased capillary pressure and the subsequent accumulation of fluid in the interstitial spaces, resulting in oedema, particularly in the lower extremities.

Understanding the mechanism behind this reaction can help in anticipating and managing potential side effects in patients receiving Diltiazem. While headaches, dizziness, and nausea can occur with Diltiazem treatment, they are typically less common than oedema. This side effect is particularly important for pharmacists to note, as it may impact adherence to therapy and the overall management of a patient’s condition.
