Urticaria and Medications for Male Pattern Baldness - Dermatology

More Info

---

Urticaria, commonly known as hives, is a skin condition characterized by raised, itchy welts that can appear anywhere on the body. It can be triggered by various factors, including allergic reactions, stress, infections, or even certain medications. In your case, it seems that you have been experiencing urticaria for the past couple of years without identifying a specific allergen. This can be frustrating and challenging, especially when it comes to managing symptoms.

Regarding the medications you mentioned, "南光快得" (likely referring to finasteride, which is used for male pattern baldness) and "好克敏" (likely referring to an antihistamine such as cetirizine or loratadine), it's essential to understand their effects on your body, particularly your liver and kidneys.

1. Finasteride (南光快得): This medication is primarily used to treat male pattern baldness and benign prostatic hyperplasia (BPH). It works by inhibiting the conversion of testosterone to dihydrotestosterone (DHT), which is responsible for hair loss in men. Finasteride is generally well-tolerated, and while it can have side effects, it is not typically associated with significant liver or kidney damage in most patients. However, it is essential to follow your healthcare provider's instructions regarding dosage and duration of use.

2. Antihistamines (好克敏): Antihistamines are commonly used to treat allergic reactions, including urticaria. They work by blocking the action of histamine, a substance in the body that causes allergic symptoms. Most antihistamines, especially the newer generation ones, are considered safe for long-term use. However, they can cause sedation, dry mouth, and other side effects. In terms of liver and kidney health, most antihistamines are metabolized by the liver and excreted by the kidneys, but they are generally safe when taken as directed. If you are taking them occasionally (as needed for urticaria), the risk of significant harm to your liver or kidneys is low.

As for your urticaria, if you have not been able to identify the trigger, it may be necessary to continue using antihistamines as needed. However, long-term use of antihistamines should be monitored by a healthcare professional. If you find that you are relying on them frequently, it may be worth discussing with your doctor about potential underlying causes or alternative treatments, such as prescription medications that can help manage chronic urticaria more effectively.

In summary, while both finasteride and antihistamines are generally safe when used appropriately, it is crucial to maintain regular follow-ups with your healthcare provider. They can help monitor your liver and kidney function through blood tests and adjust your medications as necessary. If your urticaria persists or worsens, further evaluation may be warranted to explore other treatment options or identify potential triggers. Always consult your healthcare provider before making any changes to your medication regimen.
