The goal of this clinical trial is to learn if Gabapentin works to treat flushing/erythema associated with rosacea. It will also learn about the safety of drug Gabapentin. The main questions it aims to answer are:

• Does drug Gabapentin reduce flushing and erythema associated with rosacea?
• What medical problems do participants have when taking drug Gabapentin? Researchers will compare Gabapentin to a positive control (minocycline plus hydroxychloroquine, a first-line treatment for rosacea) to see if drug Gabapentin works to reduce flushing and erythema associated with rosacea
