Introduction

1. Hypokalemia: Prolonged use of this medication may lead to decreased serum potassium levels, resulting in hypokalemia, which can sometimes manifest as symptoms such as abdominal distension and fatigue. 2. Impaired cardiac function: Long-term use may deplete Qi and damage Yang, thereby compromising cardiac function. 3. Gastrointestinal irritation: This medication may readily cause adverse gastrointestinal reactions, such as nausea and diarrhea.

Salvia miltiorrhiza tablets primarily function to invigorate blood circulation, resolve blood stasis, regulate Qi flow, relieve pain, clear heat from the Heart, and alleviate restlessness. Clinically, they are used to treat angina pectoris and palpitations caused by coronary artery disease, helping to alleviate associated symptoms in patients with this condition. So, what are the potential side effects of Salvia miltiorrhiza tablets?

What Are the Side Effects of Salvia Miltiorrhiza Tablets?

1. Hypokalemia (Low Serum Potassium)

Long-term use of this medication may lead to decreased serum potassium levels, resulting in hypokalemia. Patients may experience symptoms such as abdominal distension and fatigue—early signs of hypokalemia. This effect is primarily attributed to the vasodilatory action of Salvia miltiorrhiza, which significantly increases glomerular filtration rate and renal blood flow, thereby enhancing urinary potassium excretion and consequently lowering serum potassium levels.

2. Impaired Cardiac Function

Salvia miltiorrhiza tablets contain a relatively high concentration of borneol—a substance with a cold nature and strong aromatic, penetrating properties. Prolonged use may deplete Qi and impair Yang energy, thereby exacerbating pre-existing deficiencies of Heart-Qi and Heart-Yang in patients with coronary artery disease, ultimately leading to diminished cardiac function. Therefore, individuals with known cardiac conditions should avoid using Salvia miltiorrhiza tablets—or at least refrain from long-term or high-dose use.

3. Gastrointestinal Irritation

The borneol in Salvia miltiorrhiza tablets can also irritate the gastrointestinal tract. Consequently, patients with gastrointestinal disorders—such as gastric ulcers—as well as those with cardiovascular disease, may experience adverse gastrointestinal reactions—including nausea, vomiting, and diarrhea—following prolonged use of these tablets.

The above outlines the main side effects associated with Salvia miltiorrhiza tablets. We hope this information proves helpful to you.
