A 40-year-old member from the U.S. trekking Mount Kilimanjaro experienced an allergic reaction to Diamox, a treatment for altitude mountain sickness (AMS), which resulted in rashes, blurred vision, and vision changes. After assessment, it was determined that she required medical evacuation for further evaluation. Global Rescue organized an airborne transport to a medical facility where she was treated for her symptoms and discharged with medications. She continued her recovery at a nearby lodge, thanking the operations team for their assistance and confirming no further follow-ups were necessary.
