What Is Losartan and Why Is It Prescribed?

Losartan belongs to a class of drugs called angiotensin II receptor blockers (ARBs). It works by relaxing blood vessels, allowing blood to flow more easily and lowering blood pressure. It is frequently prescribed for:

• High blood pressure (hypertension)
• Reducing stroke risk in people with heart disease
• Protecting the kidneys in people with type 2 diabetes and hypertension

 Does Losartan Cause Hair Loss?

Hair loss is not officially listed among the common side effects of losartan. However, anecdotal reports and some case studies suggest that it may occur in rare cases.

 How Common Is Hair Loss on Losartan?

Hair loss with losartan appears to be very rare, and there’s no large-scale clinical trial that directly links losartan with alopecia. Most patients who experience hair loss are usually affected by other underlying causes such as:

• Stress or illness
• Hormonal changes
• Nutritional deficiencies
• Genetics
• Other medications

👉 According to the American Academy of Dermatology, hair loss can result from various internal imbalances, and it’s often difficult to pinpoint one cause.

Can Other Blood Pressure Medications Cause Hair Loss?

Interestingly, some blood pressure medications—such as beta-blockers (e.g., metoprolol) and ACE inhibitors (e.g., enalapril)—have a stronger association with hair thinning or loss.

👉 A review in the Journal of Clinical Hypertension showed that ACE inhibitors and beta-blockers are more frequently linked with alopecia than ARBs like losartan.

 Should You Stop Taking Losartan If You Notice Hair Loss?

If you're experiencing hair loss and suspect it may be related to losartan, do not stop the medication abruptly. Instead:

• Consult your healthcare provider
• Rule out other potential causes
• Consider alternative blood pressure medications, if appropriate

👉 The American Heart Association emphasizes the importance of discussing medication changes with your doctor rather than discontinuing blood pressure treatment on your own.

How to Manage Hair Loss If It Happens

If you and your doctor suspect that losartan is contributing to your hair thinning, here are some ways to manage it:

• Switch medications: Ask if another ARB or antihypertensive might be suitable.

• Use topical treatments: Minoxidil (Rogaine) is a common over-the-counter option.
• Consider dermatology referral: For specialized treatment and diagnosis.
