Question 3

antihistamine and zoloft (sertraline)? i take 50mg of zoloft (sertraline) daily, but i'm suffering nasty head congestion.  is it safe to take an antihistamine?

Accepted Answer

Over : Over 800 medications are known to interact with zoloft (sertraline).  Common antihistamines can interact with zoloft (sertraline), causing increased drowsiness. If you are unsure about drug interactions consult your local pharmacist, or the doctor who has prescribed the medication.

Question 4

if diphenhydramine is a sleeping pill and an antihistamine, then why is it safe to take daily for allergy but not when insomnia is the issue?

Accepted Answer

Good question.: As long as you don't exceed the dose or frequency on the label - they are equally risky/safe. Perhaps the concern more with insomnia than allergy is that sleep is a combo of physical and behavioral causes while allergy is considered all physical. So, some may think you should 1st try good sleep habits/hygiene before pills. Also they may fear dependence more w/ insomnia. Sharp thinking!

Question 5

when is it safe to take daily 10 mg zyrtec (cetirizine) after cardiac rf ablation? is there a safer antihistamine for arrhythmia patients?

Accepted Answer

Fexofenadine: There is nothing which is a 100% safe but fexofenadine would be my choice in your situation.  On the other hand, why not try a nasal spray (cortisone or antihistamine) instead if the problem is mainly nasal. This will have no effect on the arrhythmia and is more effective.

Question 6

are there any kinds of antihistamines that are safe to take with sertraline / ssris (specifically 50 mg daily)? i know many kinds increase the risk of serotonin syndrome but i'm desperate for an allergy relief?

Accepted Answer

: There is no serious interaction between sertraline and fexofenadine (allegra).

Question 7

is it safe to take two types of antihistamines togeather ?

Accepted Answer

Probably not: It is not a good idea because of the increased risk of side effects from taking multiple similar meds.

Question 8

is it safe to take two 24-hour antihistamine pills at the same time?

Accepted Answer

Depends: It could be safe or not depending on the total dose you are taking in one day.  By the way safe is conventionally defined, it will probably be safe and it will at most make you a little sleepy and contribute to reduced motor coordination, but in the context of operating a motor vehicle this could make a difference.  You may want to see a doctor to get your allergies evaluated medically. Stay safe!

Question 9

is it safe to take an expired antihistamine drug? i found a box that expired a year ago in my medicine cabinet. thanks.

Accepted Answer

Antihistamine: Expired medicine most likely loses its potency.

Question 10

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.
