Sick Note for Hay Fever: What to Bring to the Doctor
How hay fever sick leave works in the UK (fit notes, self-certification) and the US, and what to bring so your absence is visible.
On this page
Whether you take sick leave for hay fever depends on how much your symptoms stop you from working, not on the diagnosis alone. In the UK, how you prove that depends on how long you are off, and in the US it depends on your state, city and employer. To make the impact visible, bring a record of your symptom days, which you can keep in the hay fever diary in Sam and turn into a printable report instead of a scrap of paper.
This is general information about how sick leave and notes usually work, not legal advice. For your own situation, ask your employer's HR team. In the UK the independent body Acas and Citizens Advice can help; in the US an employment lawyer can advise. This text explains who decides, what a clinician weighs up, and what to take to the appointment.
Who decides whether you can take sick leave for hay fever?
In the UK, for up to 7 days you confirm your own sickness if your employer asks. After that, a clinician assesses your fitness for work for a fit note. They look at your symptoms and your job, not just the diagnosis. There is no fixed length for a hay fever absence. GOV.UK says the fit note records the functional effects of your condition so you and your employer can consider ways to help you return to work.
Your own job matters here. Someone who drives all day, prepares food, or must concentrate at a screen may be worse affected than someone with a flexible desk role. Your contribution is to describe how much the symptoms limit you. You do not decide the outcome.
What the clinician weighs up: symptoms, sleep, concentration
Hay fever is more than a runny nose. The NHS lists sneezing, a runny or blocked nose, itchy eyes and feeling tired, and its symptoms are worse between late March and September when the pollen count is high. When a blocked nose keeps you awake and tiredness makes focused work hard, that is worth saying out loud at the appointment.
Write down how it shows in your day. One line per event is enough. For example: which days symptoms appeared, which nights sleep was broken, and what you could not do because of it. Those details carry more weight than a general comment from memory.
Fit notes and self-certification in the UK
The UK system separates short and long absences. GOV.UK explains that you need a fit note only if you are ill for more than 7 days in a row, including weekends and bank holidays. For 7 days or less, you do not need one. Your employer can ask you to confirm the sick leave yourself. This is called self-certification, and you agree with your employer how you do it.
GOV.UK says a fit note can come from a GP, a hospital doctor, a registered nurse, an occupational therapist, a pharmacist or a physiotherapist, and that the professional must assess your fitness for work first.
Doctor's notes in the US
In the US there is no federal paid sick leave law, according to the Department of Labor. The Family and Medical Leave Act gives eligible employees up to 12 weeks of unpaid leave for serious health conditions, which hay fever alone rarely is. What you are paid and when an employer may ask for a note depend on your employer's policy and on any state or city rules that apply, so check with your HR team and your state or city labor department. Ask your HR team before the appointment what your workplace needs.
Bring the same record you would bring anywhere: how many days symptoms limited you, which nights sleep suffered, and what you took for it. That makes the conversation concrete whether your employer needs a note or not.
What to take to the doctor
For the clinician, a run of days is more useful than a description from memory. Bring what you have kept yourself:
- How many days you had symptoms, over a clear period such as the last four weeks.
- How many nights your nose kept you awake.
- How many days you were limited at work or in daily life.
- Which medicines you took, and for roughly how long.
An example with invented numbers: "In the last four weeks I had symptoms on 19 of 28 days. My nose kept me awake on 6 nights, and I was limited for 3 days." You can read that aloud in half a minute.
The report is your own summary. Where a fit note is needed, a clinician decides whether you are fit for work, and the report does not replace that judgement or act as proof for an employer. Before your doctor confirms hay fever, you can note symptoms in the symptom diary in Sam.
If someone is coming with you, the page Sam for family explains what relatives can take on during a visit. For how a full season looks over time, read hay fever symptoms: signs, season and diary. A wider checklist for appointments with a chronic condition is in doctor visit checklist for a chronic condition.
When hay fever is more than a bad cold
Most hay fever is uncomfortable but not an emergency. Watch for sudden swelling of the lips, tongue or throat, trouble breathing or swallowing, wheezing, or severe shortness of breath. These can be signs of a serious allergic reaction. If you suspect one, call your local emergency number (112 in the EU, 999 in the UK, 911 in the US).
The NHS also says to see a GP if symptoms get worse or do not improve after medicines from the pharmacy. Sam does not judge any of this. When you are unsure whether something is urgent, call for help anyway.
Bring your hay fever days to the appointment in Sam
You arrive with a season of symptom days instead of an answer built from memory.
- Instead of a notes app: you tap good, light or bad for each day, and add nose, eyes, sleep and activity only when you want.
- Instead of a paper list: pollen and air quality attach to the day when you share your location, where a value is available, and sleep from Apple Health sits beside it when a value exists.
- Instead of one bad day: the report (PDF) counts symptom days, nights with a blocked nose and days with limits over the period you choose.
- You print it or show it on your phone.
Sam does not issue a fit note or a doctor's note, and it is not proof for an employer. More in the hay fever diary.

Frequently Asked Questions
Can I take sick leave for hay fever?+
Yes, when symptoms stop you from doing your job. The NHS lists feeling tired among hay fever symptoms. In the UK, for up to 7 days you confirm your own sickness if your employer asks. After that, a fit note from a clinician records your fitness for work, based on your symptoms and your job, not the diagnosis alone. In the US there is no federal paid sick leave law, and the rule depends on your state, city and employer, so check yours.
Who decides how long I am off for hay fever?+
In the UK the doctor, nurse or other approved professional assesses your fitness for work and sets the fit note. There is no fixed length for hay fever. In the US, what your job requires depends on your state, city and employer. Your doctor decides through your symptoms and your work.
Do I need a fit note for a short hay fever absence in the UK?+
Usually not. GOV.UK says you only need a fit note if you are ill for more than 7 days in a row. For 7 days or less, your employer can ask for self-certification, meaning you confirm the sick leave yourself, in a way you agree with your employer.
What should I take to the doctor for a hay fever sick note?+
A record that shows how much symptoms limit you. That means which days you had symptoms, how many nights your nose kept you awake, and which days you were limited at work or in daily life. Bring the medicines you took and an idea of how long. This record is yours to keep.
Does Sam give me a sick note?+
No. Sam is a wellness companion and does not issue a fit note or a doctor's note, and nothing in Sam is proof for an employer. The report from Sam is your own summary for the conversation. A fit note, where one is needed, comes from a clinician.
Does hay fever count as a disability at work?+
Usually not on its own. In Great Britain, regulations under the Equality Act 2010 treat seasonal allergic rhinitis (hay fever) as not amounting to an impairment, unless it aggravates another condition such as asthma. In that case the effects of that other condition include the hay fever. Northern Ireland has separate disability law. In the US, the ADA defines disability as an impairment that substantially limits a major life activity. This is general information, not legal advice.
