Once the results: Return — you can determine if the rerun test showed anything. Some things can cause false positives on drug screen panels. But you will need to see what it was positive for before you can see if that might be the cause. ...Read more

Can adderall or Afrin nasal spray or a generic form of claritin d cause a positive methamphetamine result on a drug test?

Can adderall or Afrin nasal spray or a generic form of claritin d cause a positive methamphetamine result on a drug test?

Pseudoephedrine: Since the D in Claritin had been used to manufacture methamphetamine, I would suspect that it will produce a positive drug test. As for Afrin nasal spray, it is difficult to tell since any absorption would be minor and thus likely detectable only with extremely sensitive method. I hope other members in this panel will jump in on this topic. ...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 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

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

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
