Positives

• One post-COVID patient reported that after about two days in the hospital on meclizine they were able to come home, with nausea, dizziness, and vertigo improved though not gone, per a Mayo Clinic Connect discussion.
  
  
• Many patients describe relief from acute dizziness, vertigo, or nausea episodes when first started on meclizine, according to patient reviews on Drugs.com.
  
  

Negatives

• Long COVID patients on the VeDA forum report that meclizine offered minimal help and that long-term use seemed to slow vestibular compensation, per a VeDA Dizziness forum discussion.
  
  
• Patients commonly describe drowsiness, blurry vision, and dry mouth that interfere with daytime function, with some noting it didn't help at all, per Drugs.com reviews.
  
  

Hurdles & Side Effects

• Vestibular therapists generally recommend limiting meclizine to the first 1-3 days of an episode because chronic use can delay recovery, per Dr. Kim Bell's clinical guidance.
  
  
• Patients report falls and orthostatic drops, particularly when combining with other sedating medications already used in Long COVID, per WebMD's meclizine monograph.
