Not typical: An adverse reaction to dental anesthetics is rarely a true allergy but rather a psychogenic or epinepherine reaction, which is typically a racing heart, palpitations, sweating, nervousness or feeling faint. If a true allergic reaction were to happen, it would be most likely in the form of anaphalaxis.

Inflammation: Allergic reactions to local anesthetics are very rare, but possible. Depending on the type of hypersensitivity reaction, (allergy is typically termed hypersensitivity type I, or immediate) you can have different symptoms. Commonly you might experience nausea, trouble breathing, hives, itchy skin, cough, runny nose, or swelling. If you have trouble breathing, seek immediate medical attention.

LA allergy: Two distinct types of allergic reactions to local anesthetics: 1-Allergic contact dermatitis and delayed swelling at the site of administration; 2-Urticaria and anaphylaxis – These types of reaction are RARE. I have personally never seen or heard of one at dentist's office in over 40 years. Poor injection technique or sensitivity to Epinephrine in anesthetic can cause racing heart, sweating, etc.

Anaphylaxis: The most dangerous allergic reaction is anaphylaxis. With this type of reaction, the individual will develop a brisk systemic reaction (hives, swelling, breathing problems, passing out) that can rapidly progress and can cause death. The treatment is avoidance of trigger and use of injectable epinephrine.

Allergy to HIV meds: Drug allergies can occur to virtually any medication. The symptoms vary greatly. Rashes are a common sign of drug allergy, but so are joint pains and many other symptoms. Most reactions are side effects and not allergies. Here is wiki's index of which HIV medications cause which types of adverse symptoms and reactions. http://en.wikipedia.org/wiki/management_of_hiv/aids#adverse_effects.

It depends: Strictly for allergy you have the antihistamines that are divided into sedating and non-sedating. The sedating are a heterogeneous group, the commonest side effect is sedation. They can also cause dry mouth and constipation. The non-sedating have generally few side effects. The decongestants (pseudoephedrine, phenylephrine) in combinations and alone cause palpitations, restlessness and increase bp.

Indoor allergens : Indoor allergens are usually dust mites, pollens, molds, cockroache, and/or animal danders. Environmental control, minimizing exposure, may be of some help as are topical/oral medication. If those are not adequate allergen immunotherapy is usually indicated. In rare extreme situations you might need ro move, but the "grass isn't always greener". Need to see board certiified allergist.
