I'm taking zyrtec for severe case of hives. Was told to take Claritin (loratadine) in between if needed. I need more. Can I overdose if I take a second claritin (loratadine)?

I'm taking zyrtec for severe case of hives. Was told to take Claritin (loratadine) in between if needed. I need more. Can I overdose if I take a second claritin (loratadine)?

You can: Ideally I would recommend Allegra 180mg in the morning and zyrtec 10mg at night and Benadryl (diphenhydramine) in between for breakthrough hives. Take 2 clartin a day is ok, but it may not be as effective as the other 2.

Claritin (loratadine) does not take away my terrible hives caused by macrobid, will zyrtec do the job?

Could be: Sorry this happened to you! Definitely worth trying Zyrtec and maybe adding Benadryl (diphenhydramine) if there are no reasons not to.

Which is better for allergies zyrtec or claritin (loratadine)?

Zyrtec (cetirizine): Zyrtec (cetirizine) has more anti-allergy or anti-inflamatory effects than clariten (loratidine) and is often better for most allergic symptoms. It does cause drowsiness in some patients. Antihistamines work best when taken at bedtime if you are taking them on a daily basis - as in a pollen allergy or allergy to a pet that lives in your house.

Can I use Flonase and take Claritin and Zyrtec in the same day?

Can I use Flonase and take Claritin and Zyrtec in the same day?

Yes: No expected benefit of combining Zyrtec and Claritin (there are situations that call for high dose antihistamine use, but generally with one or the other). Both are safe when used in combination with Flonase.

Difference between polaramine, zyrtec and claritin (loratadine)?

All antihistamines: Polaramine is a brand of dexchlorpheniramine, a first generation sedating antihistamine similar to Chlor-Trimeton and about as effective as claritin. Claritin, brand of Loratadine and zyrtec, brand of Cetirizine are both 2nd generation, non-sedating antihistamines. Cetirizine in head to head studies with Loratadine was found to be more effective for nasal allergies and hives.

Can zyrtec or Claritin (loratadine) cause a child to have diarrhea?

Can zyrtec or Claritin (loratadine) cause a child to have diarrhea?

It's very unlikely: It's very unlikely for these antihistamines to cause diarrhea, so look for other possible explanations. If the diarrhea is transient, there's a good probability that it could be viral.

What happens if you mix allegra with zyrtec and claritin (loratadine)?

Allergy meds: Hello. Allergy medication like zyrtec, Allegra and Claritin (loratadine) help with the symptoms of allergy. The dose for an adult is 180 mg for allegra, 10 mg for Claritin (loratadine) and 10 mg for zyrtec. If you take all these meds on the same day, an increase in dryness as well as sedation will likely occur. There are other medications to help with your allergies. See your doctor.

Can I take Claritin (loratadine) in the morning and zyrtec at night. Allergies are just that bad..

Should be OK: I have also found that seasonal allergies can benefit from a sinus rinse using a Neilmed (for example), a little teapot like container with saltwater. If you take the antihistamine in the am and pm I do not think they have to be the same brand.

Need more: You might consider some of the nasal inhalants that might help. It would be best for your physician to prescribe these, or if necessary have you seen allergist they can better clarify your best therapeutic approach

Which is stronger Allegra, Zyrtec or Claritin (loratadine) I know they all treat same thing which one more likely to be Strongest?

All r created equal: But one might be more convenient (equal) to a patient than another, as different patients respond differently to different drugs, that's what they call: pharmacogenetics, a relatively new science that can tell how patients would respond to different drugs, bit expensive though to be tried on every medicine, so trial and error would be the way to go for now, good luck

Is it ok to take Claritin (loratadine) and zyrtec?

Is it ok to take Claritin (loratadine) and zyrtec?

No problem: At higher doses, for allergic rhinitis, you don't get much better effects. For chronic hives, higher doses of antihistamines can sometimes give better results.

Is loratadine less severe than zyrtec (cetirizine)?

Is loratadine less severe than zyrtec (cetirizine)?

Loratadine is weaker: When loradine (claritin) was studied the manufacturer selected the lowest dose that gave a response better than placebo but didn't have more side effects than placebo. This caused it to be a fairly weakly effective med. As it wasn't studied at higher dose I can't speak to safety of higher doses. Personally, I find zyrtec (cetirizine) to be much more effective but may be more sedating.
