Is it safe to take claritin-d every day? Are there long term side effects and what does pseudoephedrine interact with, if anything?

Allergies: In general, it it safe to take antihistamines everyday for allergies. Claritin-d includes the decongestant as you mentioned, and i tend to avoid that for people on a long term basis. It increases vasoconstriction and this has a variety of effects including more work for the heart and elevated blood pressure. There are other medications that can help with congestion. See ent/allergist. ...Read more

Is it safe to take loratadine long term, everyday, for allergies?

Prob ok: Antihistamines have been around for decades, and certainly many more potent than loratadine. They say worldwide the most common drug taken is diphenhydramine, mostly for the sedative properties (as a sleep aid). Antihistamines can affect certain types of glaucoma, and accentuate urine retention in those with prostate issues and dry mucous membranes, but usually not so much with loratadine per say. ...Read more

You have used allergy medications to treat your headache and apparently have not had benefit. I think it may be likely that your headache is not allergy related at this point. ...Read more

I'm currently taking 8 claritin (loratadine) per day. It's entirely gotten rid of my allergies. Am I harming myself by doing this? Will it damage me long term?

I'm currently taking 8 claritin (loratadine) per day. It's entirely gotten rid of my allergies. Am I harming myself by doing this? Will it damage me long term?

Yes: This is an extremely high dose, and you won't benefit on the long or even the short term, although claritin (loratadine) is OTC, it doesn't mean you can overdose without a problem, you're personally liable and should follow the instructions carefully. As for your allergies, which I don't know their nature, there are other ways to control. Check aaaai.org or acaai.org for an allergist in your area, good luck ...Read more

How long does"24-hour" loratidine (i.E. Claritin) really stay with you? Maybe 16 hours, you think?

Great question!: Loratidine is metabolized to it's active metabolite, desloratidine which has a half life of 28 hours (range 9-96). This is very long acting but there is variability among individuals based on how your liver metabolizes it which is genetically determined. If you take a drug for 5 half lives, you develop a steady state blood level ie it's more effective if you take it every day than just occ doses. ...Read more

What are the differences between loratadine and desloratidine in how well it works or how long it lasts?

What are the differences between loratadine and desloratidine in how well it works or how long it lasts?

Take one, get both: When you take loratidine, your liver breaks it down to desloratine which is actually responsible for the anti-histamine effects you need. Desloratidine has a much longer effect (28 hours) than loratidine (8 hours) which is why loratidine lasts such a long time. ...Read more
