Several pills can help manage allergy symptoms, but there isn't one single pill that stops all allergies. The best option depends on the type and severity of your allergy.
Antihistamine Pills for Seasonal Allergies
Many over-the-counter and prescription pills effectively treat seasonal allergies. These primarily work by blocking histamine, a chemical your body releases during an allergic reaction, thus reducing symptoms like sneezing, itching, and runny nose. Examples of less-sedating oral antihistamines include:
- Cetirizine (Zyrtec, others)
- Desloratadine (Clarinex)
- Fexofenadine (Allegra, others)
- Levocetirizine (Xyzal)
- Loratadine (Claritin, Alavert, others)

Other sources (Mayo Clinic) also list these medications as common options for allergy symptom relief.
Medications for Severe Allergic Reactions
For more severe allergic reactions, like anaphylaxis (a life-threatening reaction), different medications are needed. One example is omalizumab, which has been approved to reduce allergic reactions from accidental exposure to multiple food allergens. (NIH). Another medication, Xolair, is FDA-approved to reduce allergic reactions to more than one type of food after accidental exposure. (FDA).
It's crucial to consult a doctor to determine the appropriate medication for your specific allergy and its severity. There is no single "cure-all" pill, and prevention strategies (like avoiding allergens) are often necessary alongside medication. For drug allergies specifically, the only prevention is to avoid the triggering medication. (Cleveland Clinic, Penn Medicine).
