Hi. I'm Prescribed 40 Mg Of Adderall. 20 Mg 2x

Hi. I'm prescribed 40 mg of adderall. 20 mg 2x a day. I've been taking it about a year and every now and then I'll get sores on my tongue, some swelling and complete mouth dryness and my tongue burns. Can you please advise if there is anything I can pick up at Walgreens to offer some relief? Thank you.
