Is It Safe To Take Coricidin HBP Alongside Benzonatate Given I Cannot Take Antihistamines Or Decongestants?

Hi, can I take Coricidin HBP Chest Congestion and Cough with Benzonatate 200 mg? I can not take antihistamines and decongestants because of some heart palpitations, this is the reason the doctor told me to take the Coricidin HBP. I have Benzonatate and was wondering if the two together were safe. Thank you!!
