Acid Reflux & GERD
Also called: GERD, heartburn, gastroesophageal reflux disease, acid indigestion, dyspepsia
Stomach acid moving back up into the esophagus, causing heartburn and regurgitation. One of the conditions a BC pharmacist can assess and prescribe for.
Quick answer
- What it is
- A ring of muscle at the bottom of the esophagus normally keeps stomach contents down. When it relaxes at the wrong time, acid travels back up and irritates the esophageal lining.
- Common symptoms
- A burning feeling behind the breastbone, often after meals or lying down, sometimes with a sour taste, regurgitation, or a persistent cough.
- How it's treated
- Trigger and timing changes, antacids or acid-reducing medication. Longer or more frequent symptoms are usually treated with a course of a proton pump inhibitor.
- Who can help
- GERD and dyspepsia are on the list of conditions BC pharmacists can assess and prescribe for — you can be seen at Pill4Me without a doctor's appointment.
- Warning signs
- Difficulty swallowing, vomiting blood, black stools, unintended weight loss, or chest pain that could be cardiac all need medical assessment, not an antacid.

Book a pharmacist assessmentWhat is acid reflux?
Occasional heartburn is extremely common and not, on its own, a disease. It becomes gastroesophageal reflux disease when reflux happens often enough or severely enough to cause troublesome symptoms or damage to the lining of the esophagus. The dividing line in practice is usually frequency and impact: symptoms most weeks, symptoms that wake you, or symptoms that need treating regularly.
The mechanism is mechanical as much as chemical. The lower esophageal sphincter relaxes when it should stay closed, and pressure from a full stomach, lying down, or extra abdominal weight pushes contents upward. That is why timing changes — not eating within a few hours of lying down, smaller meals, raising the head of the bed — often help as much as medication does.
Reflux is also worth taking seriously when it is new in someone older, or when it comes with swallowing difficulty or weight loss, because those features can point to something other than simple reflux. That is exactly the distinction a pharmacist assessment is designed to make.
Common symptoms
Symptoms can include:
- A burning sensation behind the breastbone, often after eating or when lying down
- A sour or bitter taste at the back of the throat
- Regurgitation of food or liquid
- Feeling that food is coming back up
- Persistent dry cough, particularly at night
- Hoarseness or a frequently sore throat
- Bloating, burping or upper abdominal discomfort
- Disturbed sleep from symptoms at night
Having these symptoms does not confirm a diagnosis — they overlap with other conditions. Assessment by a pharmacist, physician or nurse practitioner is what establishes the cause.
Causes and risk factors
What causes it
- A lower esophageal sphincter that relaxes when it should remain closed
- Increased pressure in the abdomen, from a large meal, pregnancy or extra weight
- Hiatus hernia, where part of the stomach sits above the diaphragm
- Delayed stomach emptying
- Certain medications, including some anti-inflammatories, calcium channel blockers and bisphosphonates
What raises the risk of developing it
- Carrying extra weight around the abdomen
- Smoking
- Eating late and lying down soon afterwards
- Alcohol, caffeine, chocolate, mint, and fatty or spicy foods for some people
- Pregnancy
- Regular use of anti-inflammatories such as ibuprofen or naproxen
- Stress and disturbed sleep, which lower the threshold for symptoms
Risk factors make a condition more likely across a population — they are not causes, and having several does not mean you will develop it.
When should I seek medical care?
Seek urgent or emergency care
- Chest pain, pressure or tightness — particularly with sweating, breathlessness, or pain spreading to the arm or jaw. Heart attacks are mistaken for heartburn; call 911 rather than treating it as reflux
- Difficulty or pain when swallowing, or food sticking
- Vomiting blood, or vomit that looks like coffee grounds
- Black, tarry stools
- Unintended weight loss, or persistent vomiting
If you are unsure how urgent something is, call 8-1-1 to speak with a HealthLink BC nurse at any hour, or 911 in an emergency.
Worth asking a pharmacist
- Heartburn happening regularly rather than occasionally
- Over-the-counter antacids working but being needed most days
- Wanting an assessment and, if appropriate, a prescription without waiting for a doctor's appointment
- Checking whether one of your existing medications is contributing to reflux
- Reflux during pregnancy, where the safest options are worth confirming
See a physician or nurse practitioner
- Symptoms that do not improve after a course of treatment
- Reflux that keeps returning as soon as treatment stops
- Symptoms starting for the first time later in life
- Ongoing need for acid-reducing medication over months or years, which is worth reviewing rather than repeating indefinitely
How is acid reflux treated?
Lifestyle measures
- Leaving three hours between the last meal and lying down
- Smaller meals rather than large ones, particularly in the evening
- Raising the head of the bed — propping up with extra pillows does not achieve the same thing
- Identifying personal triggers, which vary far more between people than the standard lists suggest
- Stopping smoking, and reducing alcohol
- Weight management where abdominal weight is contributing
Medication
Antacids neutralise acid already present and work quickly but briefly. Alginates form a barrier on top of the stomach contents. H2 blockers such as famotidine reduce acid production for several hours. Proton pump inhibitors — pantoprazole, omeprazole, esomeprazole and others — reduce acid production more substantially and are typically used as a defined course rather than indefinitely. Which is appropriate depends on how often symptoms occur and how severe they are, and a pharmacist can assess that directly.
Monitoring
Most reflux is managed on symptoms rather than tests. If symptoms persist after treatment, return quickly each time treatment stops, or come with any of the warning features above, further assessment — sometimes including endoscopy — is arranged by a physician. Long-term acid suppression is worth reviewing periodically rather than repeating on autopilot.
This is a general overview, not a treatment plan. What is right for you depends on your history, your other conditions and everything else you take — that is a conversation with your prescriber or pharmacist.
Medications used for acid reflux
These are commonly used in Canada for this condition. Being listed here does not mean a medication is appropriate for you — that depends on your assessment.
Pantoloc
pantoprazole sodium
A prescription proton pump inhibitor for reflux and ulcers — the PPI usually chosen when someone also takes clopidogrel.
Nexium
esomeprazole magnesium
A proton pump inhibitor for frequent heartburn and reflux, available both on prescription and — at 20 mg for short courses — from the pharmacy counter.
Losec
omeprazole
The original proton pump inhibitor, used for reflux and ulcers. Available on prescription, and at 20 mg from the pharmacy counter for short courses.
Pepcid
famotidine
An H2 blocker that reduces stomach acid within about an hour — useful for occasional or night-time heartburn where a PPI would be slower.

Can a BC pharmacist assess acid reflux?
Yes — this is within pharmacist scope in BC
Gastroesophageal reflux disease and dyspepsia are both on the list of conditions BC pharmacists can assess and prescribe for under the Minor Ailments and Contraception Service. That means a pharmacist at Pill4Me can assess your symptoms, discuss treatment, and write a prescription where it is appropriate — without a doctor's appointment.
Important limits and when you will be referred
- A pharmacist can only prescribe when your symptoms fit a condition that can be identified without lab or imaging tests, that is low risk of masking something else, and that is expected to settle with short-term treatment
- You will be referred to a physician if there are warning features — difficulty swallowing, vomiting blood, black stools, unintended weight loss, or symptoms appearing for the first time later in life
- Chest pain that could be cardiac is treated as an emergency, not as reflux
- Symptoms that return as soon as treatment stops, or that need continuous treatment over months, are usually a reason for physician assessment rather than repeat prescribing
Assessments are done in the pharmacy — walk in, or book a pharmacist assessment at Pill4Me.
