Allergy & Immunology
Living with allergies or immune problems can feel unpredictable and exhausting. This Allergy & Immunology hub supports practical browsing for patients and caregivers. It covers common concerns like hay fever, asthma, rashes, and food reactions. It also explains testing terms used in an allergy clinic. Ships from Canada to US appears on many pages for access context.
Browse immune-related options in the Immunology Category. Compare items by form, use case, and prescription status. Examples here include Claritin for seasonal symptoms, Omnaris Nasal Spray for nasal inflammation, and Wixela for asthma maintenance care.
Partner pharmacies in Canada are licensed and follow local dispensing standards.
What You’ll Find in This Allergy & Immunology Category
This category brings together two helpful things in one place. It includes medication listings that relate to allergy and immune system disorders. It also includes educational content pages that explain terms, tests, and care pathways.
Patients often see both clinical and everyday words for the same issue. Allergic rhinitis (nasal allergy) may also be called hay fever. Urticaria (hives) may show up as sudden itchy welts. Atopic dermatitis (eczema) can flare with stress and irritants.
- Environmental allergies, including pollen, mold, and pet allergies.
- Food allergies and oral food challenge discussions in specialty care.
- Drug allergy evaluation topics, including past rash or swelling histories.
- Insect sting allergy basics and emergency planning conversations.
- Asthma care, including asthma management and spirometry (breathing test) terms.
- Allergy testing language, including skin prick testing and patch testing.
- Longer-term treatment terms, like allergy shots and allergen immunotherapy.
Some medication pages focus on symptom relief. For example, Diphenhydramine can appear in plans for short-term allergy symptoms. Other listings target specific allergic eye conditions, like Verkazia. Some options address certain mite allergies, such as Acarizax.
How to Choose
Allergy & Immunology care often starts with pattern tracking and clear labels. People can compare options based on symptom type and trigger timing. This helps organize questions for an allergist or immunologist.
Quick tip: Keep a short symptom log with dates, triggers, and product names.
Match the option to the main problem
- Focus area: nose, eyes, skin, lungs, or whole-body reactions.
- Trigger type: seasonal, indoor, food-related, medication-related, or unknown.
- Symptom timing: sudden reactions versus slow, ongoing inflammation.
- Past testing: note results from skin tests or blood IgE tests.
- Asthma history: include wheeze, cough, and exercise limits when present.
- Skin pattern: consider eczema flares versus contact irritation patterns.
Check practical details before comparing listings
- Form and route: tablet, nasal spray, eye drops, or topical cream.
- Daytime impact: some antihistamines may cause drowsiness for some people.
- Other conditions: glaucoma, heart rhythm issues, or prostate symptoms can matter.
- Other medicines: look for interaction warnings and duplicate ingredients.
- Age needs: pediatric allergy questions may differ from adult concerns.
- Follow-up path: testing, avoidance planning, or immunotherapy discussions.
Safety and Use Notes
Allergy & Immunology information can help people recognize risk and uncertainty. It should not replace individualized clinical judgment. Some reactions are mild and limited to one body area. Others can escalate quickly and involve breathing or blood pressure changes.
Prescriptions are confirmed with the prescriber before a medication is dispensed.
Anaphylaxis (severe allergic reaction) needs urgent medical attention. Asthma symptoms can also worsen quickly during infections or exposure spikes. Rhinitis and sinusitis symptoms may overlap with colds and irritants. Hives and chronic urticaria can have many triggers, including heat and stress.
Why it matters: Clear reaction history can speed safer decisions in urgent settings.
Drug allergy evaluation often focuses on what happened and when. Details like timing, skin changes, and other medicines matter. For insect sting allergy, clinicians may review prior reactions and risk factors. For long-term prevention, allergy shots or sublingual immunotherapy may be discussed in specialty care. These approaches need careful selection and monitoring by trained teams.
Some people need immunodeficiency assessment when infections are frequent or severe. Primary immunodeficiency can show up with unusual infections or poor vaccine responses. For broader background, see AAAAI resources on allergy care from the American Academy of Allergy, Asthma & Immunology. For emergency reaction education, see ACAAI guidance from the American College of Allergy, Asthma & Immunology.
Access and Prescription Requirements
Allergy & Immunology listings may include both prescription and non-prescription items. Some antihistamines and decongestants are sold over the counter in many settings. Many inhaled therapies and several immunology-related treatments require a prescription. Each product page notes documentation needs and key cautions.
This platform connects U.S. patients with licensed Canadian partner pharmacies for cross-border access. US delivery from Canada can support continuity for people managing chronic needs. Cash-pay options may help when coverage is limited or without insurance. Requirements vary by medication and local rules.
- Prescription items require a valid prescription from a licensed prescriber.
- Some therapies need extra checks due to higher risk profiles.
- Product pages may list refrigeration, handling, or device-training needs.
- Use the listing details to compare forms and refill compatibility.

Frequently Asked Questions
What topics are included in the Allergy & Immunology category?
This hub groups common allergy and immune system topics in one place. It can include seasonal and year-round allergies, asthma care terms, and skin concerns like eczema and hives. It may also cover food reactions, insect sting allergy, and drug allergy evaluation basics. Many hubs combine medication listings with educational content pages. The goal is easier browsing, clearer terminology, and better preparation for clinical discussions.
How is skin prick testing different from patch testing?
Skin prick testing usually checks for immediate-type allergies, often to pollens, dust mites, or foods. It places small amounts of allergen on the skin surface. Patch testing looks for delayed contact reactions, often from metals, fragrances, or topical ingredients. Patches stay on the skin longer, then a clinician reads the reaction later. The right test depends on symptom timing, body area affected, and exposure history.
What is an oral food challenge, and why is it done?
An oral food challenge is a supervised test used in some allergy clinics. A patient eats measured amounts of a food under medical observation. Clinicians may use it to confirm or rule out a food allergy. It can also help assess whether an allergy has changed over time. Because reactions can be serious, it is not a home test. Decisions about challenges depend on history and prior testing results.
When do allergy or asthma medicines require a prescription?
Prescription needs depend on the medication type and local rules. Many daily controller inhalers and some nasal sprays require a prescription. Several immunology-related therapies also require prescriber oversight. Some antihistamines are non-prescription, but strengths and formulations vary. Product pages typically note whether documentation is needed. If a prescription is required, pharmacies usually verify it before dispensing under standard safety practices.
What information helps clinicians evaluate anaphylaxis risk?
Clinicians often start with a detailed reaction history. Helpful details include the suspected trigger, timing, and symptoms across body systems. Breathing problems, faintness, or swelling can signal higher concern. They may also review asthma status, past severe reactions, and medication history. Photos of skin findings can help when available. This information supports safer decisions about testing, avoidance plans, and emergency preparedness discussions.
