I'm going to a party a friend's house but she has cats which I'm highly allergic too and so I was wondering if it's safe to drink with reactine?

Sedation: Reactine (cetirizine) is a newer generation antihistamine and is less sedating than older generation meds. However, there is still potential for sedation particularly when mixed with alcohol. Some patients are particularly sensitive to the side effects and others are not. Caution is advised and certainly avoid driving. ...Read more

Cetirizine & alcohol: Http://www. Drugs. Com/food-interactions/cetirizine.html It's always best not to drink alcohol. It is a drug that we do not need in our bodies, and there are better ways to enjoy ourselves! Drinking along with cetirizine (Reactine, Zyrtec) may increase the dizziness or sedation the medication can cause. If the medication doesn't usually bother you and you drink only a little, it might be ok. ...Read more

I took reactine six hours ago can I now take benadryl?

Yes: Antihistamine is safe even with 4x the average daily dose. The major side effects would be dry mouth and drowsiness (the latter much less common if one uses the non-sedating type). I believe reactine is equivalent to Claritin (loratadine) in the us. Short answer- it is ok. ...Read more

Reactine vs benadryl, (diphenhydramine) which one is more effective?

1st generation vs2nd: Reactine is ceterizine, a 2nd generation antihistamine supposedly non sedating, (some patients get sedated), it is a powerful antihistaminic, its main advantages over 1st generation is that patients don't develop tolerance (i.e. No need to increase the dose to keep the same effect) and is taken once daily, unlike Benadryl (diphenhydramine), 1st generation antihistamine, > once a day dosing, toleran ...Read more

Is it bad to double up on reactine allergy medicine? One doesn't do much for me. I've been taking a double dose daily for 3 months.

Better thru ur MD: Some patients need the double dose of cetirizine, but under the doctor 's supervision, I don't know what symptoms you suffer from, but at any rate if you doubled the dose on your own and still not better, you need to be evaluated, you might not need cetirizine to start with and most probably other measures would do ...Read more

Took Reactine (canadian Zyrtec) for 10+ years. Stopped yesterday and now I have rebound allergy symptoms worse than before I ever took it. Why?

Took Reactine (canadian Zyrtec) for 10+ years. Stopped yesterday and now I have rebound allergy symptoms worse than before I ever took it. Why?

Worsening allergies: So Reactine had been controlling your allergic symptoms for > 10 yrs and you have noted even more severe symptoms after stopping it. This is not from a rebound phenomenon but likely from worsening in your allergic disease with repeated exposure. Reactine may control your symptoms but not the immune response often bolstered by repeated exposure to the allergens or to new allergens. ...Read more

Usually: Urticaria (hives) is common, affecting 20% of the population. Acute hives usually resolve within 6 weeks (most patients fit into this category). Hives can become chronic if last >6 weeks.

Is using Benadryl (diphenhydramine) better than reactine to stop rhinitis? Thanks.

Both r antihistamine: Benadryl (diphenhydramine) (diphehydramine) is a 1st generation antihistamine, probably causes sedation, which might abate with continued usage, but has the problem of tolerance, (meaning u might need an extra dosage to have the same effect), reactine (ceterizine) is 2nd generation, mostly nonsedating and doesn't cause tolerance, at any rate you need to be evaluated by an allergist to better direct ur therapy. ...Read more
