What Can a Nurse Practitioner Treat Online? A Complete List

Common infections

Urinary tract infections, sinus infections, many ear infections, pink eye, and respiratory illnesses such as cold, flu, and COVID-19 are among the most frequent virtual visits. The nurse practitioner assesses your symptoms and history and prescribes treatment when appropriate.

Skin, allergies and minor issues

Rashes, eczema flare-ups, acne, mild allergic reactions, seasonal allergies, cold sores, and minor skin infections can often be assessed from a clear photo or video. Minor injuries can be triaged to decide whether in-person care is needed.

Prescriptions and ongoing care

Renewals of many regular medications, birth control, smoking-cessation support, and check-ins for stable chronic conditions are well suited to virtual care. Mental-health concerns such as anxiety, stress, and sleep are also commonly supported.

What needs in-person care

The principle: appropriateness, not limitation

The range of conditions treatable online is wide, but the organizing principle is appropriateness. If a concern can be assessed through history, conversation, and images, it is usually a candidate for virtual care. If it requires a procedure, imaging, or hands-on examination, it needs an in-person setting. This is the same standard New Brunswick applies to virtual care generally.

Evidence-guided treatment, including saying no to antibiotics

Good virtual care follows the same evidence as good in-person care. For respiratory infections, Choosing Wisely Canada is explicit that antibiotics should not be used for illnesses that are likely viral, such as colds, most sore throats, and short-duration sinus symptoms. A nurse practitioner applying these standards online is delivering high-quality care. The same evidence base guides treatment of urinary tract infections, sinusitis, and conjunctivitis.

Knowing the boundary

A closer look at the most common visits

Some concerns come up again and again in virtual care because they fit the format so well. Urinary tract infections, respiratory illnesses such as cold and flu, sinus symptoms, pink eye, skin rashes, seasonal allergies, and prescription renewals are all assessed largely through history and images. Mental-health concerns — anxiety, stress, and sleep — are likewise well served, because the assessment is conversational and the privacy of home can make it easier to open up.

For each of these, the nurse practitioner's job is to confirm the likely cause, rule out warning signs, and recommend the most appropriate, evidence-based plan — which may be self-care, a prescription, a lab requisition, or a referral. The convenience never lowers the clinical standard.

How clinicians decide what is safe to treat remotely

Behind every virtual visit is a constant judgement: can this be assessed safely without my hands and instruments? Clinicians weigh the severity of symptoms, the presence of red flags, your medical history and risk factors, and whether a physical finding would change the plan. When the answer is yes, they proceed; when it is no, they escalate.

Myths and facts about what virtual care can handle

Several myths cause people to either over- or under-use virtual care. Myth: virtual care is only for trivial issues. In fact, it handles a substantial range of genuine medical needs — infections, mental-health concerns, prescription management, and triage of more serious symptoms — while correctly escalating what needs in-person attention. Myth: you will always leave with a prescription. Good care often means not prescribing; following Choosing Wisely Canada, a clinician will decline antibiotics for viral illnesses because they would not help. Myth: a clinician cannot tell anything without examining you. Much of diagnosis is history and pattern recognition, supported by photos, which is why so many conditions are well suited to remote assessment.

On the other side: Myth: virtual care can replace the Emergency Department in a pinch. It cannot — emergencies need 911 and hands-on care, guided by the FAST stroke test and clear red flags. Myth: it is unsafe because it is remote. Regulated virtual care applies the same clinical standards and privacy protections as in-person care, with clear boundaries about what it will and will not attempt. The accurate picture sits between the extremes: virtual care is a capable, evidence-based way to handle the large middle band of everyday health needs, with honest limits at both ends. Knowing where those limits lie lets you use it confidently for what it does well — common, describable, non-urgent concerns — while turning to clinics for procedures and to emergency services for anything that could be life-threatening.

Putting it all together

The practical takeaway is that virtual care covers a genuinely broad slice of everyday health, organized around a single test: can this be assessed through history, conversation, and images? When the answer is yes — as it is for most common infections, skin and eye complaints, allergies, prescription needs, and mental-health concerns — a nurse practitioner can usually help without you leaving home. When the answer is no, because a procedure, imaging, or a hands-on exam would change the plan, the same clinician will route you to the right in-person service.

This is why virtual care is best understood as a capable first stop rather than a narrow niche. It resolves many concerns outright, triages others to the appropriate setting, and applies the same Canadian evidence — including the antibiotic stewardship that avoids prescribing for viral illnesses — that governs good care everywhere. For New Brunswickers weighing where to turn, that combination of breadth and judgement makes it a sensible default for common, non-urgent needs, while emergencies and procedures keep their rightful place in the rest of the system.
