How much time does it take Claritin (loratadine) to work?

How much time does it take Claritin (loratadine) to work?

Who knows: Work for what? Claritin supposedly starts working within 90 minutes. But Claritin is also the weakest binding antihistamine sold over the counter. Personally, I feel Claritin is a waste of money. Use a stronger antihistamine like fexofenadine or Cetirizine which cause minimal to no sedation. Use Benadryl (diphenhydramine) only at nighttime because it can make you drowsy. ...Read more

I get headaches from allergies. Can I take Claritin (loratadine) and zyrtec at the same time? Claritin (loratadine) didn't work alone when I traveled away from home.

I get headaches from allergies. Can I take Claritin (loratadine) and zyrtec at the same time? Claritin (loratadine) didn't work alone when I traveled away from home.

Yes, but: Both Claritin (loratadine) and zyrtec (cetirizine) are new generation antihistamines. While there is no harm to using them together, there is likely no added benefit either. The most effective treatment for nasal allergies is the topical nasal steroid sprays such as qnasl, flonase, veramyst, nasonex, (mometasone) etc if a person doesn't have relief with an antihistamine alone. ...Read more

Up to 1 hour: Claritin (loratadine) can work relatively quickly in most people. That is, it usually works within 30 minutes. However, in some people it may take up to 60 minutes to have its full effect. If it is not working within that time, or if the duration of effect becomes less and less, seeing an allergy specialist for allergy testing would be recommended as other treatments may be more effective. ...Read more

My husband swears Loratadine doesn't work for him unless he takes 20mg BID. What is the highest SAFE dose take?

My husband swears Loratadine doesn't work for him unless he takes 20mg BID. What is the highest SAFE dose take?

Recommended dose: The recommended daily dose is 10 mg. It is fairly a safe medicine, but side effects may arise in high doses. It seems like he is tolerating the 40 mg/day dose. The high dose definition may vary from patient to patient according their body tolerance. As he requires a large dose, he might benefit from adding different class medicine, so that he can avoid the side effects from unconventional doses. ...Read more

Stimulant medication: Both dayquil and Claritin (loratadine) d contain stimulants, so it would be duplication to take them together. The phenylephrine in dayquil is weaker than the Pseudoephedrine in Claritin (loratadine) d.

Can I take diphenhydramine and loratadine at the same time? Thanks in advance.

Can I take diphenhydramine and loratadine at the same time? Thanks in advance.

Why should you?: Loratadine (Alavert, Claritin) is a mainly non-sedating antihistamine. Diphenhydramine is very sedating and affects the brain if if you don't feel sedated. In severe itching or welts, taking more that the recommended dose of antihistamines is acceptable. I would suggest you double-up on loratadine rather than adding the other and even then only if absolutely necessary. ...Read more
