Can medications cause nails to change color? Yes, certain medications can lead to changes in nail color. This phenomenon is typically linked to drug-induced pigmentation, which can affect nails, skin, and mucous membranes. Understanding the specific causes and identifying the medications responsible are crucial for addressing any concerns about nail discoloration.
What Causes Nail Color Changes?
Nail color changes can result from various factors, including medications, underlying health conditions, and lifestyle habits. When it comes to medications, the discoloration is often due to the drug’s effect on melanin production or deposition in the nail matrix. Some medications may also cause changes in blood flow or induce photosensitivity, contributing to altered nail appearance.
Which Medications Affect Nail Color?
Several medications are known to cause nail discoloration. Here are some common examples:
- Antibiotics: Tetracycline and minocycline can cause blue-gray discoloration.
- Chemotherapy drugs: Doxorubicin and cyclophosphamide may result in brown or black pigmentation.
- Antimalarials: Chloroquine and hydroxychloroquine can lead to bluish-black nails.
- Antiretrovirals: Zidovudine (AZT) may cause brown or black discoloration.
- Psychotropic drugs: Chlorpromazine might result in grayish discoloration.
How Do Medications Cause Nail Discoloration?
Medications can lead to nail discoloration through several mechanisms:
- Melanin Deposition: Some drugs stimulate melanin production, leading to darker pigmentation.
- Photosensitivity: Increased sensitivity to sunlight can cause pigmentation changes in nails.
- Drug Metabolites: Certain drug metabolites might deposit in the nail matrix, altering color.
- Vascular Changes: Some medications affect blood flow, resulting in discoloration.
Identifying Medication-Induced Nail Changes
How to Recognize Medication-Related Changes?
Identifying medication-induced nail changes involves observing the timing and pattern of discoloration. If nail changes occur shortly after starting a new medication, it may be the cause. Typically, discoloration affects all nails uniformly, which can help distinguish it from other causes, like fungal infections or trauma.

- Consult Your Doctor: Discuss any changes with your healthcare provider to determine if the medication is the cause.
