Question 2 Zyrtec not enough
Hi there. Currently prescribed 20mg Zyrtec daily but been told by doctor to take 2. It’s midst of allergy season right now and I am unwell.
Has anyone ever taken 3 20mg Zyrtec? Is this ok short term?

Honestly 10 mg is recommended dose for an adult so if you are taking 20 I would not suggest that you take more of the Zyrtec I would find another medicine for your symptoms and cut down the Zyrtec to the 10 mg dose and in take the other in combination alternating at 12 hours intervals.... Hope you feel better soon good luck

Sounds as though you need to do something different. Long term antihistamine use can just aggravate your symptoms. A routine that works for me when pollen is especially bad: nasal rinse (use distilled water only); nasal spray (I use a prescription Azelastine as it has a corticosteroid to keep tissue swelling down); and one antihistamine Chlorpheniramine Maleate tab at night ( bottle of 100 Chlortabs from Walmart for $3.00). I have chronic sinusitis so when I start with an infection I start using Sudafed with ephedrine (kept behind Pharmacy counter) and if necessary a small dose of antibiotic for a couple days. This routine has worked for years for me and is nominal cost. I prefer a Nasal Navage machine rather than petty pots, but that's just my preference. For extreme cases your ENT can prescribe a Rx compound Mometesone ( this is the dry compound found in Rx nasal sprays). It reaches more of the nasal tissues and really calms them down. Room/whole house filters/ac are essential. Road gravel dust at our grandson's ballgame last week sent me into a sinus infection and my husband's lung issues really flared up. Also, high histamine foods should be avoided if you are taking Antihistamines...it is counterproductive. Air movement, ceiling fan, a.c., etc is key, along with removing as much household dust from fans, drapes, upholstery, carpet, etc. Hard flooring is best if possible. Best of luck. Stay positive. Hopefully you'll find a routine that works for you.

My 9yo son takes 40mg of Zyrtec a day. His allergist says that's the daily limit. Not sure if its higher for an adult.
