Three Key Points to Note When Using Topical Medications for Vitiligo
Some topical medications for vitiligo, such as immunosuppressive drugs and photosensitive drugs, can be quite irritating. Improper use may not only hinder their therapeutic effects but also cause local side effects.
Therefore, when using topical medications to treat vitiligo, patients should pay attention to the following three points.
1. Pay Attention to Any Itching in the Affected Area
Vitiligo patients have more sensitive skin. When using the medication for the first time, reduce the dosage and carefully observe any changes or sensations in the skin. If there is no pain or itching, and no other changes, then continue with the normal dosage. If discomfort occurs, stop using the medication.
2. Observe Whether Black Dots Appear on the White Patches and Whether the White Patches Shrink
Since you have chosen topical treatment, it is important to monitor the effectiveness. If the white patches are gradually shrinking or black dots appear on the white patches, the treatment is working. If after some time there are no black dots or the white patches continue to expand, stop using the medication and switch to another treatment.
3. Watch for Allergic Reactions
If there is redness, swelling, itching, stinging, or even blisters in the affected area after using the medication, it could be an allergic reaction caused by the medication.
For example, topical medications like Psoralen tincture or nitrogen mustard solution can cause contact dermatitis. In some cases, the white patches may worsen or spread due to the occurrence of contact dermatitis.
In addition, patients with vitiligo in the progressive stage should avoid using strongly irritating topical medications. When applying medication, it should only cause mild redness without swelling.
If the affected area becomes red and swollen after applying the medication, wait for the inflammation to subside before continuing use, or reduce the frequency and duration of application.If an allergic reaction occurs, stop using the medication immediately and contact your doctor to adjust the treatment plan.
