Can you take an antihistamine and a decongestant at the same time?

Are these antihistamine pills still safe to take? Help PLEASE?

• I got prescribed some antihistamine pills today for my allergy rash. They're hydroxyzine 50mg. So i went to go take one this afternoon, and a lot of them accidentally came out of the container. My hand was a bit sweaty at the time, and I could tell they got a little sticky. I just put them back into the container and took one of the pills, but I noticed the ones I put back started sticking together and to the container. I left the container open for a couple of minutes and eventually they stopped sticking together. Are they damaged? Can I still take them? I'm a bit scared. :(

• Answer:

  Histamine is an important body chemical that is responsible for the congestion, sneezing, runny nose, and itching that a patient suffers with an allergic attack or an infection. Antihistamine drugs block the action of histamine, therefore reducing these symptoms. For the best result, antihistamines should be taken before allergic symptoms get well established, but they can also be very effective if taken after the onset of symptoms. The amount your healthcare provider recommends will vary based on several factors, such as the medical condition being treated, other medical conditions you may have, and other medications you are taking. You can take hydroxyzine with or without food; however, for the medication to work properly, it must be taken as prescribed. Do not adjust your dosage without your healthcare provider's approval and supervision.
