What is This Medicine? Simply Put...

This medicine is called mixed grass pollens allergen extract. In simple terms, it is an allergy treatment designed to help your immune system build tolerance. It targets allergic reactions triggered specifically by grass pollens in your environment.

Doctors prescribe this treatment primarily to control familiar allergy symptoms. These include frequent sneezing, nasal discharge, nose itching, nasal congestion, and watery eyes. Instead of just masking symptoms temporarily, it helps train your body over time.

This medicine comes as a special tablet that dissolves under your tongue. In medical terms, this method of delivery is called sublingual administration. In many pharmacies and clinics, you might see this medicine sold under brand names like Oralair.

Important Note: Like most prescription medicines, you must use this treatment only under direct medical supervision. Never buy or take this medicine simply because you suspect you have grass allergies.

Things You Must Tell Your Doctor Before Taking This Medicine

Your doctor needs a complete picture of your health before prescribing this treatment. Therefore, you must share your full medical history openly. Tell your doctor right away if any of the following conditions apply to you:

  • Swallowing Difficulties: Do you often find it hard to swallow food, pills, or liquids safely?
  • Heart Conditions: Do you suffer from any heart disease, high blood pressure, or irregular heartbeats?
  • Respiratory Illnesses: Do you have asthma or other chronic lung and breathing conditions?
  • Mouth Sores: Do you currently have cuts, open sores, or infections inside your mouth?
  • Past Severe Allergies: Have you ever experienced a serious allergic reaction involving swollen lips, tongue, or face, trouble breathing, or throat tightness?
  • Allergy Shots: Are you currently receiving allergy shots, or have you received them in the past?
  • Other Allergies: Do you have known allergies to other medicines, specific foods, food dyes, or chemical preservatives?
  • Pregnancy and Nursing: Are you pregnant, planning to become pregnant soon, or currently breastfeeding your baby?

Sharing these vital details with your doctor helps keep you safe from unexpected complications.

To get the best results from your treatment, you must follow the correct steps every single time. Proper technique ensures the medicine absorbs properly into your body.

Side Effects and Things to Watch For

Like any medicine, this treatment can cause certain side effects. Being aware of these possibilities helps you stay calm and prepared.

Category Description and Action
Severe Allergic Signs (Call Doctor / ER) Hives, skin rash, itching, swelling of your face, lips, or tongue, trouble breathing, chest tightness, or rapid heartbeat.
Common Local Reactions (Monitor) Mild mouth numbness, tongue irritation, throat discomfort, or a scratchy feeling in your mouth. These often lessen over time.
Digestive Effects (Monitor) Mild upset stomach or mild nausea. Contact your doctor if these symptoms do not go away.

Preparing for an Emergency

In rare cases, severe allergic reactions can happen quickly. Your doctor might advise you to keep an epinephrine auto-injector nearby at all times. Your doctor will teach you and your family how to use this emergency device properly.

When to Call Emergency Services

Seek emergency medical help right away if you experience any of these red flag symptoms:

  • Severe trouble breathing or sudden wheezing.
  • Swelling of your throat, tongue, or lips that blocks air.
  • Feeling faint, dizzy, or losing consciousness.

Call 911 (US/Canada), 999 (UK), or rush to your nearest Emergency Department (ER or A&E) right away.

What to Do If You Miss a Dose or Take Too Much?

If You Miss a Dose:

If you forget to take your medicine, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose completely. Resume your normal schedule. Never take a double dose to make up for a forgotten pill. If you miss your medicine for more than one day in a row, talk to your doctor before restarting.

If You Take Too Much:

If you believe you have taken more tablets than prescribed, contact your local poison control center or go to the nearest hospital emergency department right away. Treat an accidental overdose as a serious medical situation.

❓ FAQ

Frequently Asked Medical Questions (FAQ)

Evidence-based clinical answers to common patient questions

How long do I need to take mixed grass pollens allergen extract tablets?

Doctors usually recommend starting this treatment several months before the grass pollen season begins. You continue taking the tablets daily throughout the entire allergy season. Your doctor will guide you on how many consecutive years you need treatment for lasting relief.

Can I swallow the tablet right away with water?

No, you should never swallow this tablet right away. It is designed to dissolve under your tongue so your immune system can absorb the extract properly. Swallowing it whole will make the medicine much less effective.

What should I do if my mouth feels itchy after taking the tablet?

Mild itching or numbness under the tongue is a common side effect when the tablet first dissolves. However, if the discomfort becomes severe or if you notice swelling in your lips and throat, contact your doctor right away.

Are these tablets safe for young children?

Certain brands are approved for children aged five and older. Always consult your pediatrician first to evaluate whether your child is ready for sublingual immunotherapy.

Can I take my regular antihistamines along with this medicine?

Doctors sometimes allow antihistamines to help manage breakthrough symptoms, especially when starting treatment. Always ask your doctor or pharmacist before combining any over-the-counter allergy medicines with your prescribed extract.
