I'm taking Atenolol 50 mg and lisinopril 20 mg a day if I'm in a party can I drink alcohol while taking this prescription pills?

Would be careful! Atenolol and ethanol may have additive effects in lowering your blood pressure. You may experience headache, dizziness, lightheadedness, fainting, and/or changes in pulse or heart rate. Ref: https://www.drugs.com/interactions-check.php?drug_list=273-0,1476-0,1034-14582.
