More than two years after the acute pandemic peak, long COVID — formally termed post-COVID-19 syndrome — continues to affect a significant number of people across the UK. NICE defines it as signs and symptoms that develop during or after COVID-19 infection, continue for more than 12 weeks, and are not explained by an alternative diagnosis. Community pharmacists remain a frontline resource for patients managing persistent symptoms, many of whom visit the pharmacy more frequently than their GP.
The symptom profile
Long COVID presents with a constellation of symptoms that can fluctuate over weeks and months. The most common presentations seen in community pharmacy are:
Fatigue — the hallmark symptom, reported by the majority of long COVID patients. This is not ordinary tiredness; it is a debilitating exhaustion that is not proportional to activity and is not fully relieved by rest. Patients describe "crashing" after minimal exertion — a pattern clinicians call post-exertional malaise.
Breathlessness — persistent shortness of breath on exertion, even in patients who had mild acute COVID-19. This may be accompanied by a dry cough that lingers for months.
Brain fog — difficulty concentrating, memory lapses, word-finding problems. Patients often describe feeling "not sharp" or unable to process information at their previous speed.
Pain — headaches, joint pain and muscle aches are frequently reported. Some patients develop new-onset chest pain that requires cardiac investigation before it can be attributed to long COVID.
Sleep disturbance — insomnia, unrefreshing sleep and disrupted sleep patterns are common and compound the fatigue.
What the pharmacist can advise
There is no specific pharmacological treatment for long COVID. Management is symptomatic, and the pharmacist's role is to recommend appropriate over-the-counter options while recognising the boundaries of self-care.
Fatigue management
The most important advice is pacing — the structured management of activity to avoid post-exertional malaise. The pharmacist should explain the concept: plan activities, rest before exhaustion hits, and gradually increase tolerance over weeks rather than days. NICE NG188 specifically warns against graded exercise therapy that pushes through fatigue.
Over-the-counter supplements are frequently requested. While no supplement has robust evidence for long COVID fatigue specifically, ensuring adequate vitamin D status (particularly given that many patients have been less active outdoors) and iron levels (if indicated) is reasonable. The pharmacist should check that the patient is not self-medicating with high-dose supplements that could interact with prescribed medicines.
Caffeine can help with alertness but may worsen sleep disturbance and anxiety. If patients are relying on caffeine to function, this should prompt a conversation about whether their fatigue is adequately managed.
Breathlessness
Breathing exercises — particularly pursed-lip breathing and diaphragmatic breathing — are first-line advice. The NHS Your COVID Recovery programme provides free online resources that the pharmacist can recommend.
Over-the-counter inhalers are not appropriate for long COVID breathlessness unless the patient has a pre-existing respiratory condition. If breathlessness is new and persistent, referral to the GP for spirometry and chest imaging is appropriate before any pharmacy intervention.
Brain fog
There is no over-the-counter treatment for cognitive symptoms. The pharmacist can advise practical strategies: using lists and reminders, breaking tasks into smaller steps, and reducing multitasking. If cognitive symptoms are significantly affecting work or daily life, referral to the GP for neuropsychological assessment is warranted.
Pain
Paracetamol and ibuprofen remain the first-line analgesics for long COVID-associated headache and musculoskeletal pain. The pharmacist should review the patient's full medication list to avoid interactions — particularly if the patient has been prescribed amitriptyline or gabapentin for pain by their GP.
Sleep
Sleep hygiene advice is first-line: consistent wake times, no screens in the hour before bed, cool bedroom, limited caffeine after midday. Over-the-counter options include short-term use of diphenhydramine or promethazine, though these should be used cautiously given their anticholinergic effects and the risk of dependence.
When to refer
The pharmacist should refer the patient to their GP or to an NHS long COVID clinic if:
- Symptoms have persisted for more than 12 weeks and are not improving
- There are new or worsening symptoms — particularly chest pain, palpitations, or significant weight loss
- Breathlessness is worsening or limiting daily activities
- Mental health symptoms (depression, anxiety, suicidal thoughts) are present
- The patient is unable to work or carry out normal activities
NHS England established over 90 post-COVID assessment services across England. Referral is typically through the GP, but some services accept self-referral. The pharmacist can help by identifying patients who may benefit and encouraging them to seek assessment.
The ongoing pharmacy role
Long COVID is a chronic condition that requires ongoing support. Community pharmacists see these patients regularly — often more frequently than any other healthcare professional — and are well placed to monitor symptom progression, review self-medication, and provide the continuity that a condition with fluctuating symptoms demands.
