Cat allergy shots: Immunotherapy or "shots" for cat allergy are usually only effective at preventing symptoms with brief exposures to cat, like visiting a friend with a cat. Having a cat in your house will usually overwhelm the effect of the "shots" and you will experience symptoms. Also, there is no such thing as a hypoallergenic cat. All cats have skin which produce dander which causes allergic symptoms. ...Read more
Varies: Some reactions are mild, such as hives alone. Others are more serious, with breathing problems and blood pressure drop. Some reactions (like some kinds of rashes) are not actually allergies, but different reactions that may or may not recur when you take the medicine.

Yes but...: Antihistamines can be taking twice a day safely if required but there are other treatments available. If by allergic reaction you are referring to seasonal allergies, the gold-standard therapy is daily nasal steroid sprays and/or antihistamine nasal sprays. Nasal saline rinses, avoidance measures, and if refractory to treatment, allergy shots can also be helpful. See an Allergist for more details. ...Read more

Usually: Recent studies have found that a majority of people who are allergic to penicillin can tolerate cephalosporin (of which Keflex is one) and particularly the 3rd generation one. However if you have had an anaphylactic reaction to penicillin, you should check with your allergist before you considering taking any cephalosporin. The risk is very low but it is better to be safe than sorry. ...Read more
Many: You need to avoid penicillin and amoxicillin plus a few related drugs but other antibiotics can usually be tolerated. Cephalosporin cross-sensitivity is possible (as much as 10%) but I have rarely seen one in my practice. The cross-sensitivity in the newer generations of cephalosporin is even rarer. ...Read more
Anything not PCN ok.: Actually the incidence of a true IgE mediated reaction to Penicillin is less than 1% of the population at large. Thankfully there are many alternatives to penicillin for treating susceptible organisms. The big question that occurs almost always is can a penicillin allergic pt be given a cephalosporin. The true incidence of real crossover sensitivity to "cephalo's" is anywhere from 0.5% to 10% ...Read more
Usually fast: Most common allergic reactions to pollen, insect stings, foods, etc., are immediate hypersensitivity reactions, meaning they occur within seconds to minutes. But you can also have a late phase, a second-wave of reaction that occurs hours later. Contact allergies (poison ivy, nickel allergy, e.g.) and some medication allergies are delayed, and may take hours, days, or weeks. ...Read more

It depends: Are you allergic to cepfrozil? If you are, it depends on what kind of a reaction you had in the past. If it was a late small rash, another exposure may be just a somewhat worse rash. If you had a severe allergic reaction, the next may be life-threatening. Without knowing what kind of a reaction you had, I can't be more specific. ...Read more
Don't do it: Too many possibilities here. Depends on the type of allergies - don't fool around. Blistering, mucous membrane reactions can get started and are very difficult to control, even life threatening. Go see an allergiest who can guide you through, and have testing that can help eliminate possible problems. ...Read more
Hours to days: If the rash you have is from a recent and brief exposure, if you have some topical benedryl cream, it should resolve relatively quickly. If you have had prolonged exposure, you might need to add a topical steroid for relief. This might take a couple of days. Finally, if the rash is infected, see your doctor as that might not heal on its own. ...Read more
Depends: Most food allergic reactions will subside in 1-2 days depending on treatment. Poison ivy contact dermatitis allergic reaction can sometimes take a few weeks. Most drug allergic reactions improve after a few days depending on how fast the body "metabolizes" the drug and it stays in the system. ...Read more
No, see Allergist: If you have a history of an immediate reaction to one of the inactive ingredients in a medication then I would avoid, taking an equally efficacious alternative that lacks this specific ingredient. If there are no alternative medications, and you absolutely require it, see an allergist in order to determine your risk for ingesting this product in the future. ...Read more
Yes: Itching can indicate an allergy. I would recommend discontinuing the medication and seeing your doctor. ...Read more
Variable: All I can say is variable. Once someone has developed an allergy to something a reaction will take place fairly quickly after exposure.
