Petechiae rash?

Question

Can a petechiae rash be caused by the ingredients in NyQuill (liquid, cold/flu) if you have never had an allergic reaction to any of those ingredients before?

I've never had any type of allergic reaction to medication before but wouldn't it be a different type of rash than a petechiae rash?

Thanks

Answer 1

Petechiae can be caused by many things. First you should do a glass slide test. press a clear piece of glass onto the rash and see if it blanches (turns white). If not see a doctor soon. Any drug allergy can mimic any other skin condition, so it is possible that this is a drug reaction, but it is also possible that it is RMSF (rocky mountain spotted fever), group A beta hemolytic strept, scarlet fever, or measles or something else. If you have symptoms enough to take Nyquil and a rash, the best advice that I could give you is to see a doctor as it is impossible to diagnose a skin condition or even an allergy over the internet.
Probably not too serious, but needs to be looked at!

Answer 2

Petechiae can be caused by many, many things. If the cause is unknown to you, have a doctor check it out.

Allergies or any trauma to the skin such as, inflammation, an infection, or a previous infection site that is healing are common minor causes that will go away eventually. This can take a few weeks or a few months depending on the severity of the trauma.

Other major causes are everything from cancer to low platlet counts in the blood. Thats why it is important to have a doctor check the rash out if it is spreading or you dont know what is causing it.
