Allergies (I think) really bad. Claritin-D usually works, but not so much now. Worth switching or ride out? Allergy meds aren't cheap. So congested!

Allergies (I think) really bad. Claritin-D usually works, but not so much now. Worth switching or ride out? Allergy meds aren't cheap. So congested!

Try Zyrtec/Allegra: Try Zyrtec or Allegra (or their generic versions cetirizine or fexofenadine, which are cheaper) or Xyzal (all OTC). Buy the plain versions (without 'D'), and buy pseudoephedrine ('D') separately (behind-the-counter, but no Rx required) and add it to your antihistamine as needed for nasal congestion symptoms. Allergy drug and decongestant separately cost less. Dose instructions are on packages. ...Read more

Well: Well presence of allergies, hyper inflated lungs on cxr and dyspnea suggest asthma. You can have normal pfts (pulmonary function tests) ad still have asthma. I am not sure you have been tried on but usually you need blood test or skin test for allergies and a total ige level (blood test). You could try inhalers on regular basis for example advair or Dulera (formoterol and mometasone) on twice a day basis and see if this will help you symptomatically. Some times treatment of asthma can become difficult and will need some patience at your and your doctors end.
Hope this helps. ...Read more

Claritin D sleep works great to clear nighttime nasal congestion but now I'm awake and jittery due as side effect. Other options? (mucinex (guaifenesin) D)?

Claritin D sleep works great to clear nighttime nasal congestion but now I'm awake and jittery due as side effect. Other options? (mucinex (guaifenesin) D)?

Don't use "D": The "D" in many medications is causing your side effects of being awake and jittery. Please only use oral antihistamines without the "D" to help with nasal congestion - zyrtec, allegra, claritin. You can also try OTC nasal steroid sprays. ...Read more

I accidentally took two Claritin D about one hour apart. This is the 12-hour formula. Is there a problem with this?

I accidentally took two Claritin D about one hour apart. This is the 12-hour formula. Is there a problem with this?

Unlikely: You've had a double dose of the decongestant which can keep you from sleeping well, increase your heart rate and increase your blood pressure. The double dose of Claritin is unlikely to cause you any issues in the next 12 hours. I do not think you need any immediate medical attention unless you develop any concerning symptoms. ...Read more

Can I take Claritin d 12 hour (pseudoephedrine and loratidine) at morning and night every day?

Claritin-D: Claritin (loratadine)-d 12 hour can be taken twice daily chronically but it can have side effects. Taking a decongestant can lead to hypertension or insomnia. I would recommend trying claritin-d in the morning and just standard Claritin (loratadine) at night. This would give you the best treatment with minimal side effects. ...Read more

I am 14 weeks pregnant I took a Claritin D just once is that ok as long as I don't take it again or can it hurt baby?

You're just fine: Claritin D won't hurt your baby even more than once, claritin (loratadine) is category B, while D (pseudoephedrine) is category C, with pregnancy, B is safer than C though, but both are safe, confer with your obstetrician on the next prenatal care visit, wish you a healthy pregnancy and a healthy baby ...Read more
