Varies: Depending upon the medication used, the time until the onset of effect will vary. Generally antihitamines work relatively quickly and inhaled steroids may take a week or so to have ful effect.

Still around: Chlortrimeton is still available as an over the counter allergy medication. It is available as a generic chlorpheniramine tablet as well. Keep in mind that this antihistamine can cause sedation.

Allergy shots: Allergy medications will not take you a long way if you want to live with a cat. I suggest you see an allergist, get tested then get allergy shots for cats before you get one.

Anyone know what is a stronger allergy medicine?

Dr. Jack Mutnick

Allergy medicine: The basics are that Claritin (loratadine) is the weakest binding oral no sedating antihistamine with Allegra stronger and zyrtec binding the strongest. You need to be more specific with your question.

What is considered the most effective allergy medicine to take?

Depends: The most frequently used and most available without a prescription are antihistamines. The new generation ones (zyrtec, claritin, allegra, xyzal, (levocetirizine) clarinex) are safe and effective. The most effective treatments for allergic rhinitis are nasal steroid sprays. The strongest allergy medication would likely be considered oral steroids like prednisone, but the significant side effects limit is use.

Many: The most effective allergy treatment for allergic rhinitis is the prescription nasal steroid sprays (qnasl, flonase, nasonex, (mometasone) etc) over the counter antihistamines can be very effective including claritin, zyrtec, and allegra. Some people will respond better to one over the other (for unclear reasons). The best long term therapy for significant environmental allergies is allergy injections.
