Dr. Long Ly, a Board-Certified Dermatologist at MetroDerm in Atlanta, is among the expert contributors featured in a recent article from The CheckUp from SingleCare®, titled “Metronidazole for rosacea: Dosage, uses, and side effects.” In the piece, Dr. Ly shares his clinical expertise to help readers better understand rosacea – a common but often misdiagnosed skin condition – and the treatment options available to manage it. His insights highlight the importance of accurate diagnosis and personalized care, offering valuable guidance for patients seeking effective solutions for persistent redness and inflammation.
Rosacea typically presents as persistent redness across the cheeks, nose, chin, and forehead. While it can sometimes be mistaken for acne or skin sensitivity, rosacea is a chronic inflammatory condition that requires a tailored approach to care.
“There is no specific test to diagnose rosacea. Instead, a Dermatologist will review a patient’s signs and symptoms along with their medical history,” says Dr. Ly.
“Because rosacea can resemble other conditions, your Dermatologist may consider things like acne, seborrheic dermatitis, contact dermatitis, or perioral dermatitis. These have similar symptoms, but also important differences. For example, acne often involves blackheads and whiteheads, while rosacea does not,” Dr. Ly adds.
Rosacea symptoms can vary widely from person to person. Some individuals experience persistent facial redness and visible blood vessels, while others may develop acne-like bumps or experience burning and stinging sensations. Flare-ups can be triggered by a variety of factors, including sun exposure, stress, spicy foods, alcohol, and extreme temperatures. Because of this variability, treatment is rarely one-size-fits-all.
Topical and oral medications are commonly used to manage rosacea symptoms, along with lifestyle modifications to reduce triggers. Among the most widely prescribed treatments is metronidazole, a medication used for decades due to its effectiveness and tolerability. Metronidazole is typically applied as a cream, gel, or lotion and works by reducing inflammation and targeting microorganisms on the skin that may contribute to flare-ups. While it is technically an antibiotic, its anti-inflammatory properties are what make it particularly beneficial for rosacea patients.
Patients using metronidazole often notice gradual improvement in redness and a decrease in the number of inflammatory lesions over several weeks. It is generally well tolerated, though some individuals may experience mild side effects such as dryness, irritation, or a slight burning sensation at the application site. As with any medication, consistency and proper use are key to achieving the best results.
In addition to traditional therapies like metronidazole, advancements in Dermatology have introduced newer options for managing rosacea.
“Newer treatments like Ivermectin cream and laser therapy can also help manage symptoms of rosacea-related acne,” shares Dr. Ly.
These options can be particularly helpful for patients who do not respond fully to first-line treatments or who are seeking more targeted solutions.
Ultimately, successful management of rosacea depends on a personalized approach that considers each patient’s unique skin type, triggers, and lifestyle.
“Your Dermatologist will help create a personalized treatment plan based on your medical history, symptoms, skin type, and lifestyle,” Dr. Ly says.
This individualized care ensures that patients not only address their current symptoms but also reduce the likelihood of future flare-ups.
With the right combination of medical therapy, lifestyle adjustments, and expert guidance, rosacea can be effectively managed – helping patients achieve clearer, healthier skin over time.
