Side Effects of Qutong Pian
Qutong Pian (Pain-Relieving Tablets) is a compound analgesic containing four primary active ingredients: aminopyrine, phenacetin, caffeine, and phenobarbital. Its main adverse effects are also attributable to these four components. So, what are the side effects of Qutong Pian? Below is an explanation.

Side Effects of Qutong Pian
Qutong Pian belongs to the class of nonsteroidal anti-inflammatory drugs (NSAIDs). Its predominant adverse effects involve the gastrointestinal (GI) tract. It may stimulate gastric acid secretion, cause acute gastric mucosal injury, damage the gastric mucosa, and predispose individuals to gastric or duodenal ulcers—potentially leading to gastric hemorrhage. Additionally, hematologic abnormalities may occur, such as leukopenia (a reduction in white blood cell count). Use of this medication should be strictly supervised by a physician, with contraindications carefully ruled out prior to administration. Patients should thoroughly read the package insert before use to understand precautions and potential adverse reactions, and must adhere strictly to medical instructions. Elderly patients are at increased risk of renal impairment when using this drug; therefore, close monitoring for adverse effects is essential. Moreover, prolonged use may lead to dependence and tolerance—meaning that over time, higher doses may be required to achieve the same analgesic effect for the same degree of pain.

1. Risk of Neurological Dysfunction
Qutong Pian may readily induce neurological dysfunction, causing harm to the body. While it can temporarily relieve pain, it may also produce adverse effects such as neurological disturbances and insomnia. Therefore, caution is warranted when using analgesics to avoid inflicting additional harm or unnecessary complications. Alternative approaches—such as applying a warm compress (e.g., hot water bottle) or drinking ginger–brown sugar tea—may help alleviate symptoms.
2. Risk of Dependence
Long-term use may result in drug resistance and dependence. Although Qutong Pian provides rapid pain relief, it must not be taken indiscriminately, as this may exacerbate pain or trigger other discomforts. With continued use, tolerance develops, necessitating progressively higher doses while achieving diminishing therapeutic benefit. Thus, Qutong Pian should only be used occasionally—not as a long-term treatment strategy.
