How effective is Claritin (loratadine) d to help with allergy asthma?

Antihistamines help: Claritin (loratadine) +/- d, zyrtec +/- d, or Allegra +/- d can help with allergy and asthma symptoms caused by allergies to respiratory pollens or other airborne allergens. One should work with his doctor to see which combination of over-the-counter allergy meds and prescription asthma inhalers/pills work the best. A patient will learn over time, what medicines to adjust, depending on how "bad" the air is. ...Read more

Allergies (Definition)

Allergies occur when your immune system is triggered by envirionmental factors it should ignore--for example, pollen in the air, or dander on a cat or dog--and creates cells to fight against them. An allergic reaction typically causes itching, congestion, or drainage, and ...Read more

Could I take singular for asthma and take Claritin (loratadine) and lohist-d for allergy at the same time?

Could I take singular for asthma and take Claritin (loratadine) and lohist-d for allergy at the same time?

Yes: Singulair (montelukast) and Claritin work by different mechanisms. The combination of both works better than either alone for allergy control and the singulair (montelukast) may help your asthma as well. ...Read more

Nasal steroid sprays: The most effective treatment for nasal allergies are nasal steroid sprays such as flonase, qnasl, nasonex, (mometasone) veramyst, etc. These are safe and effective, but a person needs a prescription from their doctor. ...Read more

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

I took Benadryl at 11 PM for my allergies. Can I take my regular Claritin-D at 11 AM the morning after? Benadryl was a one time thing for night relief

No problem: But do realize that the D in Claritin may raise your blood pressure and may not be good as a long-term medication. Nasal steroid is usually more effective and safer in the long run. ...Read more

I just purchased 24 hour Claritin D Non-Drowsy for allergies. Should I take this in the AM or PM? Can I consume alcohol while taking Claritin D?

I just purchased 24 hour Claritin D Non-Drowsy for allergies. Should I take this in the AM or PM? Can I consume alcohol while taking Claritin D?

A.m.: Because most of the decongestant is released during the day, you may have insomnia if you take it at night- even then the lingering effect of the decongestant may still disrupt your sleep. Yes there is no problem with alcohol in moderation. ...Read more

I take Prozac 20mg and wellbutrin (bupropion) XR 150mg once a day. Is it safe to take claritin-d for my allergies while on these meds?

Drug interactions: 1. Prozac and welbutrin (i think you mean xl) both potentially increase the level of claritin (loratadine). There should be normal liver enzymes on record as this is the mechanism that potentially causes problems.
2. There are other potential interactions between Prozac and welbutrin, especially with any seizures or head injury.
Discuss all with your doctor to be sure you are being safely monitored. ...Read more

Which is best for coughing and runny nose (allergies) sudafed or Claritin (loratadine) or claritin-d?

Neither: If you are sure you are dealing with allergies, then an antihistamine is the drug of choice. Sudafed is a decongestant. Claritin is a weak antihistamine and despite the drug labelling can cause drowsiness as can zyrtec. Allegra (fexofenadine) does not cross the blood-brain barrier and thus no drowsiness. A nasal spray either steroid or non-steroid is also useful. ...Read more

Chronic post-nasal drip 1 yr. Tried everything allergy & reflux. ENT given me Claritin-D (240mg pseudo) & oral steroid 5 wks to break cycle. Thoughts?

Chronic post-nasal drip 1 yr. Tried everything allergy & reflux. ENT given me Claritin-D (240mg pseudo) & oral steroid 5 wks to break cycle. Thoughts?

Allergist evaluation: If you have access to an allergist, kindly seek their evaluation, you may very well have allergic rhiosinusitis, the medications you used would have some benefit, but need to be taken on regular basis, not as needed basis or for short courses, of course the systemic steroids can't be for long course unless really indicated, but local steroid sprays would do the trick, meanwhile. Good luck ...Read more

How long is it safe to take Claritin D? D seems to be the only thing help chronic post nasal drip and fluid in ears. On allergy shots but slow progress.

BP Concerns: The decongestant in Claritin (loratadine) D can be helpful for acute facial pain/pressure and congestion but has side effects which can be significant. If you have a history of blood pressure issues or other cardiac problems I would not recommend. Consider talking with Allergist about other possible treatment due to refractory disease. Drying agents like ipratroprium bromide sprays and methscapolomine can help ...Read more

Can you take Claritin (loratadine) and hydrocodone-homatropine syrup together? I am having really bad allergies and a cough, I am asthmatic as well.

Can you take Claritin (loratadine) and hydrocodone-homatropine syrup together? I am having really bad allergies and a cough, I am asthmatic as well.

CNS depressant: The combination can be sedating. When combined, homatropine and Claritin (loratadine) can cause anticholinergic side effects. If a patient has previously used both medications in the past without any side effects, the combination should be fine in setting of asthma, "real bad allergies" and cough. ...Read more

My sister age 16 has insomnia for the first time what should she do to cure it? She doesn't wheeze. She takes an inhaler for asthma and loratadine.

My sister age 16 has insomnia for the first time what should she do to cure it? She doesn't wheeze. She takes an inhaler for asthma and loratadine.

Many reasons: There are many reasons for insomnia. If she is taking Loratadine d, the "d" part can keep people awake. Occasionally antihistamines will also keep people awake.
