    Default Hmmmm could be risky

    Now available Over-The-Counter (OTC); No prescription needed.

    DRUG DESCRIPTION

It has a molecular weight of 382.89, and empirical formula of C22H23CIN2O2; its chemical name is ethyl 4-(8-chloro-5,6-dihydro-11H-benzo[5,6]cyclohepta[1,2-b]pyridin-11-ylidene) -1-piperidinecarboxylate and has the following structural formula:


    CLARITIN Tablets contain 10 mg micronized loratadine, an antihistamine, to be administered orally. It also contains the following inactive ingredients: corn starch, lactose, and magnesium stearate.

CLARITIN REDITABS (loratadine rapidly-disintegrating tablets) also contain the following inactive ingredients: citric acid, gelatin, mannitol, and mint flavor.

    What are the possible side effects of loratadine?

    Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

    Call your doctor at once if you have a serious side effect such as:

    fast or uneven heart rate;
    feeling like you might pass out;
    jaundice (yellowing of your skin or eyes); or
    seizures (convulsions).
    Less serious side effects may include:

    headache;
    nervousness;
    feeling tired or drowsy;
    stomach pain, diarrhea;
    dry mouth, sore throat...

    Default Good News

    Hey guys,

    I thought it was really odd how Cetirizine had shown no effect on PGD2, particularly since Cetirizine is far more effective than Loratadine (Claratyne) & Fexofenadine (Telfast) when it comes to SKIN allergies.

    So I did a lot of digging and found that within 5 hours of its oral use it inhibits PGD2 production in the skin by at least 50%!

    I think the previous study was looking at PGD2 levels in nasal mucosa. I guess it makes sense. For example, antihistamines don't seem to work when you have a runny nose due to a cold (minimum effect on PGD2 in the nose) so we have to resort to Sudafed (Pseudoephedrine) to dry up and unblock our nose

    Here's a study for you guys to look at. This was conducted during its approval process

    http://www.ncbi.nlm.nih.gov/pubmed/2469708

    So, stick to Cetirizine for now, until I dig up more info on Cromolyns.

    P.S. If Cromolyns are more effective, there's a product called INTAL SPINCAPS, which are Cromolyn based capsules that go into a inhaler device. We can just open one capsule everynight, mix it with Emu oil & Propylene Glycol & voila

    Hi Desmond

    Can I just take zyrtec tablets orally then? It seems much easier than making a topical and I don't want to mix up everything into a solution. But if the topical is the best method I will try that. Thanks

    Injesting it orally gives you more risk of side effects. I believe it gives the same benefit but less side effects if you use it topically.

    EDIT: and On a side note I love how we're all becoming researchers right now. Screw the FDA trials!!(sarcasm kinda, I know they're for safety but still, 3-5 years is a long wait for hairloss!).

    I think the issue with taking them orally is the dose. If you apply 10mg topically you will get a much higher dose to the scalp than if you take it orally where it will diffuse throughout your entire body.

    You'd have to take a shed load of pills to get the same concentration in your scalp which would have systemic effects. So I think topical is the way to go.

    One concern I have is we have no idea how much cet will go systemic from topical application. But I guess if you apply 10mg then no more than that can do systemic. Perhaps much less. I have no idea how much of a drug is typically going to go systemic from application to the scalp. I guess it varies widely.

    Any thoughts Des?

    I wanna try the topical but don't want to she'd to much as I'm a Norwood 1 and what's the chance of keeping my hair with this topical or growing it back?
