Introduction
Under normal circumstances, dexamethasone is available in various dosage forms including tablets, injection solutions, and creams. Its side effects may include weight gain, elevated blood sugar levels, osteoporosis, gastrointestinal ulcers, and suppression of the immune system. During treatment with dexamethasone, it is important to closely monitor physical changes, strictly follow medical instructions for medication use, and not to adjust the dosage or discontinue the medication without consulting a healthcare provider.
Generally, dexamethasone is available in various dosage forms, including tablets, injection solutions, and creams. Its side effects may include weight gain, elevated blood glucose levels, osteoporosis, gastrointestinal ulcers, and suppression of the immune system. A detailed explanation is as follows:
1. Weight Gain
Dexamethasone promotes redistribution of fat and increases appetite, leading to rapid weight gain within a short period. Central obesity may also occur, characterized by relatively slim limbs and significant fat accumulation in the trunk area.
2. Elevated Blood Glucose Levels
This medication may promote hepatic glycogenolysis and reduce glucose uptake and utilization by peripheral tissues, resulting in increased blood glucose levels. In diabetic patients, it may make the condition difficult to control, while long-term use in non-diabetic patients may induce steroid-induced diabetes.
3. Osteoporosis
Dexamethasone inhibits osteoblast activity, reduces bone matrix synthesis, and simultaneously promotes osteoclast formation and activity, increasing bone resorption. Long-term use can easily lead to bone loss and an increased risk of fractures.
4. Gastrointestinal Ulcers
The drug stimulates the secretion of gastric acid and pepsin while inhibiting gastric mucus secretion, thereby reducing the protective effect of the gastric mucosa. This increases the likelihood of developing gastrointestinal ulcers such as gastric ulcers and duodenal ulcers. In severe cases, gastrointestinal bleeding and perforation may even occur.
5. Immune System Suppression
Dexamethasone has immunosuppressive effects, reducing the body's immune defense functions. This weakens the body's resistance to pathogens such as bacteria and viruses, increasing the risk of infections. Additionally, symptoms after infection may be atypical, easily delaying diagnosis and treatment.
During the use of dexamethasone, it is important to closely monitor bodily changes and strictly follow medical instructions regarding medication use. Do not adjust the dosage or discontinue the medication on your own. If long-term treatment is required, it is recommended to regularly undergo related examinations such as blood glucose, blood pressure, and bone density tests to promptly detect and manage potential side effects.
