Here are a few options for the description of the WordPress post_tag “長期服用” (Long-Term Use) in Traditional Chinese, depending on the specific context and intended audience:

**Option 1: General and Informative:**

* **標籤描述：** 指示藥物或其他治療方式的持續使用，通常超出建議的短期療程。此標籤可用於記錄或分類需要長期監控、評估或潛在風險的醫療資訊。 (Indicates the continuous use of medication or other treatment methods, typically beyond the recommended short-term course. This tag can be used to record or categorize medical information that requires long-term monitoring, assessment, or consideration of potential risks.)

**Option 2: Focus on Potential Concerns:**

* **標籤描述：** 描述長期服用藥物對健康可能造成的影響。涵蓋長期使用可能導致的副作用、耐藥性、或互相影響之疑慮。 (Describes the potential health effects of long-term medication use. This encompasses concerns about side effects, drug resistance, or interactions that may arise from prolonged use.)

**Option 3: Relevant to a specific medical field (e.g., Chinese Medicine):**

* **標籤描述 (中醫方向)：** 指示中藥或療法需要持續使用的情況。常見於慢性病或其他需要調理的體質，需長期耐心調整才能達到效果。(Indicates situations where Chinese medicine or other therapies require continuous use. This is common for chronic illnesses or other conditions that require conditioning, where the results are achieved over a long period of patient adjustment.)

**Option 4: Simple and to the point:**

* **標籤描述：** 描述藥物或療法必須持續使用一段長時間的情況。(Describes the situation where medications or therapies must be used continuously over an extended period.)

**Key Considerations when choosing:**

* **Target Audience:** Who are you writing for? Are they patients, doctors, researchers, or a general audience?
* **Purpose of the Tag:** How will this tag be used within your website? Is it for organizing information, highlighting potential risks, or something else?
* **Clarity and Accuracy:** The description should be clear, concise, and accurately reflect the meaning of “長期服用.”

I recommend choosing the option that best suits your specific needs and the overall context of your website. You can easily edit the description later if needed.
