What Medications Can Cause Dry Skin?
There are several medications that may cause dry skin as a side effect, including:
Isotretinoin (Accutane): This acne drug depletes oils from the skin, which can cause dryness. Antacids: Antacids require high amounts of moisture to be active in the body. Statins: Statins are cholesterol-lowering drugs, and they can reduce the amount of fat stored in the skin, which leads to dryness. Chemotherapy: Dry skin is one of the side effects of chemotherapy for cancer.
Complications and Risk Factors Associated With Dry Skin
At times, untreated dry skin can lead to various forms of eczema, including:
Atopic eczema (atopic dermatitis): When the skin reacts to triggers like chemicals or fabrics by getting red, itchy, and flakyAsteatotic eczema: Red, flaky skin that is more commonly seen in older adults, usually at the shinsDiscoid eczema: A type of eczema common in those who bathe too often, and that includes dry, flaky discs on the skin.
Untreated dry skin could also lead to itchy skin and infections if the skin’s surface is not strong enough to protect the body. Persistent dry skin could also indicate an undiagnosed health issue, like an under-active thyroid or blood sugar problems. It could also indicate an autoimmune disorder like psoriasis.

Using mild soaps with moisturizing ingredientsAvoiding alcohol-based products and other strong chemicals, like harsh detergentsMoisturizing with ceramidesUsing lukewarm instead of hot water for bathing and bathing once a dayUsing a humidifierDrinking more water to stay hydratedIdentifying dry skin triggers, like soaps or fabrics
If your dry skin can’t be treated at home, you might talk to your healthcare provider about:
Prescription topical steroid creams for dry and itchy areas Treating health problems that cause dry skin, like hypothyroidism, diabetes, or psoriasis Any medications you’re taking, in case dry skin is a side effect
Summary
Dry skin is when the skin lacks moisture because of low oil or water. It can be caused by aging, weather, bathing too often, harsh soaps and chemicals, or underlying issues like eczema, psoriasis, low thyroid, diabetes, and other conditions.
Treating dry skin can include moisturizing several times a day, avoiding hot showers or baths that are too long, staying hydrated, using a humidifier, and treating any underlying health issues that could cause dry skin. It’s also important to test for undiagnosed health issues that can cause dry skin.
If dry skin cannot be treated at home, or if itchiness occurs without a rash, it’s advised to seek medical attention. A healthcare provider will likely ask about family and medical history and examine the skin. A blood test could also be needed in case of a more serious illness.
A Word From Verywell
Dry skin can affect how we feel about ourselves, but the good news is that it’s largely treatable at home. Thicker lotions, keeping bathing water lukewarm, avoiding harsh soaps, and staying hydrated are simple ways to get softer skin at a low cost.
If your dry skin doesn’t seem to go away, it’s important to consider underlying health issues, like low thyroid or diabetes. However, these conditions are treatable, and with the proper treatment, you can get back to soft skin in good time.
