After taking 2 days of Claritin (loratadine) d 24 hour then stopping how long can I expect the side effect to last. It stimulated my anxiety.

After taking 2 days of Claritin (loratadine) d 24 hour then stopping how long can I expect the side effect to last.  It stimulated my anxiety.

About 24 hours: Decongestants like the 'D' in this version of Claritin (loratadine) can have side effects like restlessness, increased heart rate and blood pressure. It's an extended release formula which helps it last 24 hrs. After that 24hrs, the last bit of the D to be released should be pretty much out of your system within another 24hrs. If having prolonged or worrisome symptoms, seek medical care. ...Read more

If one tablet isn't controlling your symptoms, better see your doctor, you may need some other medicine ...Read more

Conflicting advice from two drs on Claritin (loratadine) d otc. One says take indefinitely, other stop?

D is decongestant: Claritin-d contains two drugs, an antihistaminic named Loratadine and a decongestant adrenergic called pseudoephedrine. It is best to use each drug according to what is intended for. Antihistaminics are to control histamine release and decongestant to reduce swelling and secretions. Continuous use of antihistaminics are helpful for perennial allergies, such as to dust mite. ...Read more

What to do if i had six little blue Claritin (loratadine) clear pills, mixed with two ibuporfens. What will this do to me?

Drowsiness: You will likely get some drowsiness with 6 Claritin (loratadine) tablets and perhaps a little stomach upset from the ibuprofen. The question is why would you do this? If you are trying to OD , please call the suicide hotline since I see little reason for using this combination of drugs. ...Read more

Can i take two loratadine tablets?

Can i take two loratadine tablets?

Yes, but why ?: Studies of loritadine show the medication is well tolerated at twice the recommended 10 mg dose. However, the same studies show no added benefit of the double dose in symptom relief over the regular dose schedule. If one is not working well, you may want to try otc fexofenadine or a steroid nasal spray. ...Read more

Can I safely take two 10 mg doses of loratadine in one day?

Can I safely take two 10 mg doses of loratadine in one day?

It may make u Drowsy: The full adult dose of Loratadine in other parts of the world is 20 mg. This amount caused a 12-14% drowsiness rate. The 10 mg dose was tested in the us in order to find a non-drowsy dose and it worked. If your allergy symptoms are controlled with Diphenhydramine (benadryl-50% drowsiness) and not 10 mg loratadine, you can try a second 10 mg dose and it may help with a lot less drowsiness. ...Read more

How much of an effect will Loratadine have on panel testing if inadvertently taken within a day or two of beginning the test?

How much of an effect will Loratadine have on panel testing if inadvertently taken within a day or two of beginning the test?

Not much: if anything. By panel testing, I presume you mean standard blood tests measuring usual chemistries done for a check-up. If by panel testing you mean allergy skin tests, the recommendation is to avoid antihistamines for a full 48 hours prior to testing as the drug may diminish otherwise positive skin test reactions. Drugs of abuse tests should not be affected. I hope this helps. Stay well:) ...Read more
