Back Metoprolol can cause lichen planus ? 21 Feb, 2026

Yes ✅ — Metoprolol can cause lichen planus, but it is rare.

More accurately, it can cause a condition called:👉 Lichenoid

Drug Eruption (LDE)

This looks very similar to classical lichen planus but is triggered by a medication.


💊 Beta-blockers & Lichen Planus

Beta blockers including:

  • Metoprolol

  • Propranolol

  • Atenolol

have been reported to cause lichenoid eruptions.


🔬 What Happens?

Metoprolol may trigger a T-cell–mediated immune reaction, leading to skin lesions that resemble lichen planus.


📍 How to Differentiate?

FeatureClassical Lichen PlanusDrug-Induced (Metoprolol)
CauseIdiopathic / AutoimmuneDrug triggered
OnsetSpontaneousWeeks–Months after starting drug
DistributionWrists, anklesMore widespread
Oral involvementCommonLess common
ResolutionChronicImproves after stopping drug

⏳ When Does It Appear?

Usually:

  • 1–6 months after starting metoprolol

  • Sometimes even later


🔁 Does It Go Away?

Yes 👍
If metoprolol is the cause:

  • Lesions improve after stopping the drug

  • May take weeks to months to fully clear

  • Topical steroids help during recovery

⚠ Never stop metoprolol suddenly — consult doctor first.


🩺 What Should Be Done?

If a patient on metoprolol develops lichen planus-like rash:

  1. Clinical evaluation

  2. Review drug history

  3. Consider biopsy if needed

  4. Doctor may switch to another antihypertensive (e.g., ACE inhibitor or CCB)


🎯 Final Answer:

✔ Yes, metoprolol can rarely cause a lichenoid drug eruption, which mimics lichen planus.
