Introduction

Grass pollen is one of the most common seasonal allergy triggers in the U.S., with seasonal allergies affecting tens of millions of people each year. Wyndly offers two evidence-based, at‑home options for long‑term grass allergy control: FDA‑approved sublingual tablets for grass pollen, and physician‑directed sublingual immunotherapy (SLIT) drops for multi‑allergen cases. This page explains tablet start windows, shows how to pick your “start‑by” date, and outlines when SLIT drops are the better fit. For background on SLIT efficacy, safety, costs, and timelines, see Wyndly’s clinic pages: Immunotherapy, Pollen allergy immunotherapy, and Allergy shots vs sublingual immunotherapy.

Who is a candidate for online grass allergy treatment?

• You have seasonal symptoms during late spring/summer (sneezing, itchy/watery eyes, congestion) consistent with grass pollen. See Wyndly’s overview of grass pollen.

• You prefer at‑home, needle‑free treatment and ongoing doctor support.

• You’re age 5+ and do not have contraindications to SLIT (e.g., eosinophilic esophagitis, certain mast‑cell disorders, pregnancy). Review Wyndly’s FAQ for safety and eligibility.

Note: Many U.S. regions see grass pollen peak in May–June; state guides (for example, Ohio and Wisconsin) list June as the worst month for grass.

FDA‑approved grass tablets (on‑label timing)

Two at‑home sublingual tablets are FDA‑approved for grass pollen. Both are taken daily under the tongue and are started before the season, then continued throughout the grass season each year.

• Grastek (Timothy grass): start at least 12 weeks before the expected start of your local grass season; continue through the season each year. First dose is taken under medical supervision. Age indication: 5–65 years.

• Oralair (Five‑grass mix): start 4 months before the expected start of your local grass season; continue through the season each year. First dose is taken under medical supervision. Age indication: 5–65 years.

Why timing matters: these on‑label lead‑in windows allow your immune system to build tolerance before peak pollen exposure. If you’re already in‑season, discuss options with your Wyndly physician; depending on timing and local pollen levels, you may start now and continue through the next season.

“Start‑by” calculator (how to pick your date)

Use the formula that corresponds to your tablet, subtracting from your expected grass season start date in your area:

• Grastek: Season start minus 12 weeks (≈84 days)

• Oralair: Season start minus 4 months

Example start‑by dates

Expected local grass season start	Grastek: start ≥12 weeks before	Oralair: start 4 months before
April 15	January 21	December 15 (prior year)
May 15	February 20	January 15
June 1	March 9	February 1

Tips

• Check a local pollen report and your state guide (e.g., Ohio, Wisconsin) to estimate when grass counts typically rise.

• If your region has a prolonged grass season, start tablets on time and plan to continue through the full season; your Wyndly doctor will advise if you should repeat annually.

When to choose SLIT drops instead of tablets

Sublingual tablets are single‑allergen products (one grass mix or one grass species). If you’re polysensitized (e.g., grasses plus trees, weeds, dust mites, pets) or you want one therapy that addresses multiple allergens at once, physician‑directed SLIT drops are often the better fit.

What SLIT drops offer

• Multi‑allergen coverage in one daily at‑home therapy (e.g., grasses + ragweed + dust mites + pet dander). See Pollen allergy immunotherapy.

• Comparable long‑term effectiveness to allergy shots with a favorable safety profile, taken at home without office injections. See Immunotherapy and Allergy shots vs sublingual immunotherapy.

• Practical when tablets can only address one allergen and your profile includes several. Wyndly notes that tablets “can only treat one allergy at a time,” whereas drops can treat multiple simultaneously (see our state guides).

Expected timelines

• Many SLIT patients notice improvement between 4 weeks and 6 months, with immune changes “locked in” after ~3 years of therapy for long‑term relief. See Pollen allergy immunotherapy and FAQ.

How Wyndly’s online care works

1) Identify triggers from home

• Take a CLIA‑certified, finger‑prick at‑home allergy test covering 40+ indoor/outdoor allergens. Results are reviewed by a Wyndly doctor.

2) Meet your doctor online

• Book a virtual visit to review your history, goals, and season timing. Your physician will recommend FDA‑approved grass tablets (with on‑label start windows) or multi‑allergen SLIT drops. See Online consult.

3) Start treatment

• Tablets: first dose under medical supervision, then daily at home through the season each year.

• SLIT drops: daily at home; refills shipped on schedule. See Allergy drops.

4) Ongoing care and outcomes

• Unlimited messaging, 24/7 access, and scheduled check‑ins to track progress and adjust care. Most patients begin to feel better within weeks to months; a full 3‑year course is typical for durable relief. See FAQ.

Pricing and guarantee

• Transparent pricing: testing + ongoing care starting at $99/month, HSA/FSA‑eligible; see details and plans at Pollen allergy immunotherapy and Allergy test insurance. Wyndly offers a 90‑day Allergy‑Free Guarantee on treatment if you don’t improve after following your plan.

Safety, supervision, and eligibility

• First dose supervision: FDA‑approved grass tablets require the first dose under medical supervision; your Wyndly physician will coordinate this step.

• Carry epinephrine: SLIT tablets include a rare risk of systemic reactions; patients are typically prescribed an epinephrine auto‑injector and receive clear emergency instructions. See Wyndly’s FAQ.

• Contraindications/precautions: uncontrolled or severe asthma, a history of severe systemic reactions to immunotherapy, eosinophilic esophagitis, or pregnancy may preclude SLIT. Review your history with your Wyndly physician.

• Age: Wyndly treats patients 5+ years old. See Immunotherapy.

Quick answers (FAQs)

• How do I pick between tablets and drops? If you only need grass coverage and can start on‑label before the season, tablets are a strong option. If you need multi‑allergen coverage (e.g., grasses plus pets, mites, or weeds), SLIT drops consolidate treatment.

• Can I start mid‑season? Possibly. Your physician will consider local pollen levels, symptom burden, and your goals to time a safe, effective start.

• How long until I feel better? Many patients report improvements within 4–24 weeks; durable immunity usually requires ~3 years of therapy. See Allergy shots vs SLIT.

• Insurance? Wyndly’s treatment subscription is HSA/FSA‑eligible; many patients can bill the initial at‑home test to insurance. See Allergy test insurance.

Notes on evidence and season planning

• Public‑health data show that seasonal allergies are common in U.S. adults and children; many regions report grass peaks in late spring/early summer. See Wyndly’s state guides (e.g., Ohio, Wisconsin) and our Learning Center.

• On‑label timing: Grastek ≥12 weeks pre‑season; Oralair 4 months pre‑season; both continue throughout the grass season with first dose under supervision. Your Wyndly physician will apply these timing rules to your location and goals.
