Final answer:
Tussionex Pennkinetic ER is associated with hydrocodone and chlorpheniramine, not acetaminophen, codeine, diphenhydramine, or pseudoephedrine. Epinephrine is the medication used to counteract the effects of anaphylactic shock, not antihistamines.
Step-by-step explanation:
The medication associated with Tussionex Pennkinetic ER is hydrocodone and chlorpheniramine. This combination medication is used to treat cough and upper respiratory symptoms caused by allergies or the common cold. Hydrocodone is a narcotic cough suppressant, while chlorpheniramine is an antihistamine that relieves allergy symptoms. Tussionex Pennkinetic ER does not contain acetaminophen, codeine, diphenhydramine, or pseudoephedrine, which are choices listed in the question.
To answer the additional question, the drug used to counteract the effects of anaphylactic shock is epinephrine. Antihistamines can be used as well but are not the primary treatment for anaphylaxis. Epinephrine is the first-line medication for anaphylactic reactions due to its rapid onset of action in reversing the life-threatening symptoms of anaphylaxis.
