Can I get treated online for allergy symptoms?

Yes. A licensed provider on Ondoc reviews your symptoms and, when appropriate, prescribes treatment for the underlying cause — most commonly Allergic rhinitis or Chronic sinusitis.

How fast will I hear back?

Most online visits are reviewed in under 24 hours. Refills are often same-day.

Allergy symptoms

Sneezing, itchy eyes, runny nose, and congestion that recur with seasons are usually allergies. A provider can prescribe stronger antihistamines or nasal sprays online.

Seek urgent care or the ER if you have:

Symptoms that are sudden, severe, or rapidly worsening
High fever (over 103°F / 39.4°C) that doesn't respond to treatment
Chest pain, trouble breathing, fainting, or confusion
Signs of dehydration — dizziness, dark urine, unable to keep fluids down
Symptoms in someone who is pregnant, immunocompromised, or over 65

What allergy symptoms could be

The most common causes a clinician considers. This isn't a diagnosis — it's the differential a provider works through with you.

Allergic rhinitis

Allergic rhinitis is one of the more common causes of allergy symptoms. A provider can confirm with the right history, exam, or labs — and start treatment the same day when appropriate.

Chronic sinusitis

Chronic sinusitis is one of the more common causes of allergy symptoms. A provider can confirm with the right history, exam, or labs — and start treatment the same day when appropriate.

Allergic reaction

Allergic reaction is one of the more common causes of allergy symptoms. A provider can confirm with the right history, exam, or labs — and start treatment the same day when appropriate.

Typical workup

What a clinician usually orders or asks about when someone presents with allergy symptoms.

Focused history: timing, triggers, severity, and prior treatments related to "allergy symptoms"
Targeted physical exam of the involved system
Rule-in / rule-out workup for the most likely causes: Allergic rhinitis, Chronic sinusitis, Allergic reaction
Labs, imaging, or referral only when the answer will change management

When to see a clinician

Symptoms have lasted more than a few days without improving, or keep coming back
You're not sure if this needs antibiotics, prescription treatment, or watchful waiting
You have a chronic condition (diabetes, heart disease, immunocompromised) that raises the stakes
You want a same-day plan without a trip to urgent care
