You should treat a red, itchy rash under your Fitbit band:
Remove your Fitbit to soothe and heal your skin.
To remove dirt and sweat, gently wash the area with mild soap and lukewarm water. Avoid scrubbing to avoid skin irritation. Avoid aggravating the rash by patting it dry with a soft towel.
Calamine lotion or aloe vera gel can relieve itching and inflammation. These products reduce pain and promote healing.
You must also find the rash's cause to prevent it. Common causes include skin irritation, especially for sensitive skin. Fitbit band material or skin friction can irritate. Nickel and latex in Fitbit bands may cause allergic reactions in some people. Try a hypoallergenic band if you suspect an allergic reaction. Consult a doctor if the rash worsens.
