Does vistaril enhance the effects of oxycodone?

Yes. First generation antihistamines (i.e. Vistaril, Benadryl) increase the analgesic effects of most opiates so that a lower dose of opiate can be given. Antihistamines also reduce some of the side effects, such as itching and nausea. Vistaril can also inhibit the enzyme that metabolizes Oxycodone, but I think that is negligible unless the Vistaril dose is very high (over 100mg).

Can you take Claritin and veramyst at the same time?

No, you do not take two antihistamines at the same time. You may choose either benadryl OR Claritin, but not both. Overdosing on antihistamines causes severe sedative effects which might make you become confused or pass out. You might have trouble breathing. You will get twice the drying out effects, and will almost certainly get a splitting sinus headache or nosebleed.
