Can hyperthyroidism cause acne?


Hello doctor, I was diagnosed with hyperthyroidism in early March.
After taking medication for about a week, I noticed signs of acne and stopped the medication.
Then, in early June, I had blood tests again and after taking the medication for another week, I noticed acne again.
I would like to ask if this could be a side effect of the medication.
I am quite anxious about this because appearance is very important in the service industry.
Some doctors mentioned it could be an allergic reaction; I’m not sure if that’s the case.

Dear Cai Cai,
There are not many reports linking hyperthyroidism to acne; however, medications containing iodine used for hyperthyroidism can cause acne.
Proper adjustment of the medication dosage, along with the use of topical and oral acne treatments, can help suppress the occurrence of acne.

Wishing you peace and health.
Sincerely,
Dr.

Hyperthyroidism, or an overactive thyroid, can indeed have various effects on the skin, including the potential exacerbation of acne. The thyroid hormones play a significant role in regulating metabolism, and when they are elevated, they can influence the sebaceous glands, which produce oil in the skin. Increased oil production can lead to clogged pores, which is a primary factor in the development of acne.
In your case, it seems that you have experienced the onset of acne after starting medication for hyperthyroidism. It is important to note that certain medications used to treat hyperthyroidism, such as antithyroid drugs (like methimazole or propylthiouracil), can have side effects that may include skin reactions. These reactions can range from mild rashes to more severe allergic responses. However, the development of acne specifically is not commonly listed as a direct side effect of these medications.

The timing of your acne flare-ups, occurring shortly after starting or resuming your medication, raises the possibility that your skin reactions could be related to the hormonal changes induced by hyperthyroidism itself or the medications you are taking. Stress, which can also be a factor in hyperthyroidism, may further exacerbate skin issues, including acne.

If you suspect that your acne is a side effect of your medication, it is crucial to consult with your healthcare provider. They can evaluate your symptoms in the context of your overall treatment plan. They may consider adjusting your medication or exploring alternative treatments that might be less likely to cause skin issues. Additionally, they can assess whether your acne could be related to other factors, such as hormonal fluctuations, diet, or stress levels.

In the meantime, it is essential to maintain a proper skincare routine. This includes using non-comedogenic products that do not clog pores, gentle cleansing, and moisturizing. Over-the-counter topical treatments containing benzoyl peroxide or salicylic acid can also help manage acne. However, it is advisable to consult with a dermatologist before starting any new treatments, especially considering your current health condition.

If you are experiencing significant distress due to the acne, especially given your role in the service industry where appearance may be particularly important, discussing this with your doctor can help you find a suitable solution. They may refer you to a dermatologist who specializes in treating acne and can provide targeted therapies that are safe to use alongside your thyroid medication.

In summary, while hyperthyroidism can contribute to skin changes, including acne, it is essential to work closely with your healthcare team to determine the underlying cause of your symptoms and to find an effective treatment plan that addresses both your thyroid condition and your skin health.
