I Have Been Taking Esomeprazole 20 Mg For Approx 2

i have been taking esomeprazole 20 mg for approx 2 month as i have been diagnosed with a ulcer. i have started to get red rashes on my forehead and temple areas plus puffed eye lids. is this a common side affect. the esomeprazle are really helping with my heart burn caused by my ulcer. is there alternative medication my doctor could prescribe me, thanks
