Anti histamines: You can take either an antihistamine or H2 blocker (or both immediately following using an epipen (epinephrine). It may help stop a worsening allergic reaction. Anti histamines block H1receptors and H2 blockers work on H2 receptors so you are blocking both histaminic receptors. Best is to avoid whatever you are sensitive too in the first place.

Antihistamines: If you are pregnant and itching that badly you need to see your care provider to rule out possibly serious conditions such as cholestasis of pregnancy. If serious conditions are ruled out than you can try antihistamines such as Claritin zyrtec or Benadryl (diphenhydramine) as well as oatmeal baths like aveeno and emollient skin creams such as eucerin. Make sure your air is well humidified as well

Nitrates/tylenol: Eds pts should avoid nitrates when using eds drugs such as viagra. Children are usually given tylenol (acetaminophen) based on safety over many years. However all forms of analgesics can be use in children depending on the circumstance. All doses will need adjustment.

Avoidance: It depends on what symptoms are caused by dust mite allergy and exposure. Most common would be nasal syptoms (allergic rhinitis) and oral antihistamines or topical steroids or antihistamines are very effective. Dust mite exposure in allergic people also can contribute to allergic eczema (atopic dermatitis) and asthma. They are treated in the usual way. But best is to avoid dust mite exposure.

What's the best decongestant to use when you have a stuffy nose?

1 doctor answer1 doctor weighed in
Dr. Barbara Stark Baxter
Allergy and Immunology 42 years experience
Decongestants: Oral Pseudoephedrine is the most effective pill, but oral phenylephrine is the most available, because you do not have to have a driver's license handy to identify yourself when purchasing it. Both can disturb sleep. So at night a lot of people choose topical decongestants, for example afrin, (oxymetazoline) Vicks spray, 4-way spray, etc. Those sprays can be addicting. Spray antihistamines work well if allergic.
