Question 3

i took a zyrtec and flonase this morning. would like to take muscinex fast max with antihistamine for the evening and wondering if that is ok?

Accepted Answer

Yes, but: be cautious still with antihistamines overdose, i.e. stay with only one antihistamine in the following days, till the cold symptoms are over, good that you asked, always exercise caution with multiple medications

Question 4

is it safe to take another 24-hour zyrtec (cetirizine) antihistamine if there's still about 8 hours left before the previous one wears off?

Accepted Answer

Zyrtec (cetirizine): You can take another xyrtec but you may become very sleepy.

Question 5

what if i am concerned my hives are caused by an antihistamine in the first place? i.e. zyrtec and allegra (fexofenadine)

Accepted Answer

Very rare : Hives usually come and go randomly.  So you may confuse an outbreak with being caused by something else (though not really). So best to see an allergist.

Question 6

zyrtec or allegra (fexofenadine) for hives: which is the better antihistamine?

Accepted Answer

Zyrtec (cetirizine): Which drug is better fora specific patient cannot be predicted. I generally try zyrtec first because it does cannot claim not sedating. A little sedation helps alleve itching. Allegra, (fexofenadine) claritn, and Clarinex are allowed to claim no sedation.

Question 7

i'm looking for a natural antihistamine for seasonal allergies rather than using zyrtec (cetirizine)?

Accepted Answer

Natural treatments : Natural treatments are medications too. Usually not as well studied or characterized for benefit and safety as those approved by the fda.  I don't know of any natural antihistamines per se but butterbur has been reported to have benefits. A very safe alternative to allergy medicine  is buffered saline washes. These can be purchased or home made but certain hygienic guidelines should be followed.

Question 8

which antihistamine(s) do not cause or worsen anxiety and depression? i am currently taking zyrtec and want to switch to another antihistamine. also, i will be starting escitalopram soon.

Accepted Answer

Options: Your likely best options are from the group of antihistamines that are known not to enter the brain in significant amounts. This differs from Zyrtec that does.The chemical names include fexofinidine &amp; loratadine. There are no listed interactions with escitalopram. How your system will react to any medication will require a trial use.

Question 9

is it ok to take zyrtec (cetirizine) (antihistamine for allergies) and dayquil (cold/flu medicine) together?

Accepted Answer

Depends: If you are taking plain zyrtec (cetirizine) (antihistamine only) you can take dayquil, but you should not take nyquil which also contains an antihistamine. Zyrtec (cetirizine) d contains a decongestant and antihistamine so it should not be mixed with other meds such as dayquil.  It is always important to read the ingredient labels of any over the counter medicines as many medicine contain the same or similar ingredients.

Question 10

do you still need to take antihistamines such as claritin or zyrtec if you are using nasacort (triamcinolone)?

Accepted Answer

Allergic Rhinitis: Nasal steroids and oral antihistamines are complimentary, and are often used together in the treatment of allergic rhinitis.
