What Is Influenza (Flu) in Adults?
Influenza is a contagious respiratory illness caused by influenza viruses, most commonly influenza A and B. It typically presents with sudden onset of fever, chills, muscle aches, headache, cough, sore throat, and profound fatigue. While many otherwise healthy adults recover without complications, older adults and those with chronic medical conditions are at higher risk for pneumonia, hospitalization, and other serious outcomes.
Antiviral medications such as oseltamivir (Tamiflu) work best when started early in the course of illness and are reserved for patients who are at higher risk or significantly symptomatic. Telehealth is well suited to evaluate symptoms, confirm likely influenza, and decide who may benefit from antivirals versus supportive care alone.
During your TeleDirectMD visit, an MD reviews your symptom timeline, exposure history, vaccination status, and risk factors to differentiate influenza from COVID-19, common colds, and other conditions, and to identify any red flags that require in-person or emergency care.
Symptoms and Red Flags for Adult Influenza
This table highlights common influenza symptoms versus findings that should trigger in-person or emergency care.
| Symptom | What It Suggests | Telehealth Appropriate? | Red Flag Requiring In-Person or ER Care |
|---|---|---|---|
| Sudden high fever and chills | Typical onset pattern of influenza or other acute viral infection | Yes, if breathing is comfortable and oral intake is adequate | Seek urgent care if fever is very high, persistent, or accompanied by confusion or severe weakness |
| Severe body aches and fatigue | Common with influenza and helps distinguish it from many colds | Yes, telehealth can guide supportive care and work planning | In-person evaluation if accompanied by chest pain, shortness of breath, or neurologic changes |
| Cough and sore throat | Frequent in influenza, COVID-19, and other viral respiratory infections | Yes, telehealth can assess pattern and recommend testing when needed | In-person care if cough is severe, productive with blood, or associated with chest pain or labored breathing |
| Headache | Common with influenza and other viral illnesses | Yes, if mild to moderate and responsive to routine medications | ER evaluation if abrupt, severe “worst headache” or associated with stiff neck or neurologic changes |
| Nasal congestion and runny nose | Seen with influenza but also colds and allergies | Yes, appropriate for telehealth symptom management | In-person care if associated with facial swelling, vision changes, or severe sinus pain |
| Shortness of breath with exertion | May represent lower respiratory involvement or deconditioning | Telehealth can triage mild symptoms if speaking in full sentences | ER care if shortness of breath occurs at rest, worsens rapidly, or impairs speech |
| Chest pain or tightness | Concerning for pneumonia, heart strain, or other serious illness | No, beyond uncomplicated influenza telehealth care | Requires urgent in-person or emergency evaluation |
| Persistent vomiting or inability to keep fluids down | Raises risk for dehydration and complications | No, telehealth alone is not appropriate | Requires urgent in-person or ER evaluation |
| Confusion or difficulty waking | Signs of possible severe systemic or neurologic involvement | No, not manageable by telehealth alone | Emergency evaluation is needed immediately |
| High-risk conditions with worsening symptoms | Higher risk of complications in adults with chronic disease or older age | Telehealth can assess for antivirals and higher level of care needs | In-person or ER care if rapid deterioration, chest pain, or severe shortness of breath develops |
How We Distinguish Influenza from COVID-19, Colds, and Allergies
Many respiratory illnesses share overlapping symptoms. During your TeleDirectMD video visit, your physician uses symptom timing, severity, vaccination history, exposure risk, and available test results to narrow down the most likely diagnosis and decide whether antiviral treatment is appropriate.
- Influenza (flu): Often abrupt onset with higher fever, prominent body aches, headache, and fatigue. Cough and sore throat are common, and overall illness may feel more severe than a typical cold.
- COVID-19: Fever, cough, sore throat, congestion, fatigue, and body aches. Loss of taste or smell, when present, is more characteristic of COVID-19 than influenza, though patterns can overlap.
- Common cold (viral upper respiratory infection): Usually milder with more nasal congestion and runny nose, lower fever, and less intense body aches or fatigue than classic influenza.
- Allergic rhinitis: Itchy eyes, sneezing, clear runny nose, and exposure to seasonal or environmental triggers, usually without fever, severe body aches, or systemic symptoms.
- Bacterial pneumonia or other serious lung disease: High fevers, productive cough, shortness of breath, chest pain, and systemic illness requiring in-person evaluation and imaging.
The goal is to identify which adults may benefit from oseltamivir, who can recover with supportive care alone, and who needs prompt in-person or emergency evaluation.
When a Video Visit Is Appropriate for Flu Symptoms
When a TeleDirectMD Video Visit Is Appropriate
- Adult, generally stable, able to speak in full sentences
- Fever, chills, body aches, cough, sore throat, or fatigue without severe distress
- Able to drink fluids and keep down medications
- Within the antiviral treatment window if at higher risk for complications
- No chest pain, marked shortness of breath, or confusion
- Comfortable using home tests when available and a nearby pharmacy
Red Flags Requiring In-Person or ER Care
- Severe shortness of breath, especially at rest
- Chest pain, pressure, or pain with breathing
- Confusion, difficulty waking, or new neurologic symptoms
- Very low oxygen readings at home compared with baseline (if available)
- Persistent vomiting or inability to keep fluids or medications down
- Very high or persistent fever with signs of systemic illness
- Rapid worsening of symptoms in a high-risk adult
If any red flag is present, do not rely on virtual care alone. Seek urgent in-person or emergency evaluation promptly, and call emergency services if there is concern for life-threatening illness.
How TeleDirectMD Treats Adult Influenza
TeleDirectMD emphasizes evidence-based supportive care, careful risk assessment, and appropriate use of oseltamivir for adults at higher risk of complications. Not every patient with influenza needs antiviral medication.
Supportive and Symptom-Based Care
- Guidance on home isolation, masking, and protecting higher-risk household members
- Use of acetaminophen or ibuprofen when appropriate for fever, headache, and body aches
- Hydration strategies and rest planning during the acute phase
- Discussion of safe over-the-counter options for cough, congestion, and sore throat
- Monitoring symptoms over time and clear instructions on when to escalate care
Oseltamivir (Tamiflu) Eligibility
For adults at higher risk for complications or with significant symptoms, oseltamivir may modestly reduce illness duration and risk of severe outcomes when started early. TeleDirectMD evaluates your risk factors, symptom timing, and medical history to determine whether oseltamivir is appropriate.
Stewardship and Safety
- Antivirals are reserved for adults who are likely to benefit, based on risk profile and timing
- We do not prescribe antibiotics for uncomplicated viral influenza
- We do not prescribe controlled substances or unproven flu therapies
- All medication decisions are individualized using current adult influenza guidelines when applicable
Common Medications for Adult Influenza (Telehealth-Appropriate)
Medication choices depend on risk factors, timing of symptoms, and other medications. The table below shows examples of commonly used options in eligible adults. Exact dosing and suitability are always individualized.
| Medication | Dose | Duration | When It Is Used |
|---|---|---|---|
| Oseltamivir (Tamiflu) | 75 mg by mouth twice daily | 5 days | For eligible adults with suspected or confirmed influenza at higher risk for complications and within the treatment window |
| Oseltamivir renal-adjusted dose | Dose adjusted based on kidney function | 5 days | For selected adults with reduced kidney function who still meet criteria for oseltamivir |
| Acetaminophen | Typical adult doses not exceeding recommended daily maximum | As needed during acute illness | Used to reduce fever and relieve aches in adults without contraindications |
| Ibuprofen or other NSAIDs | Typical adult doses within recommended limits | As needed during acute illness | Used for fever and pain relief in adults who can safely take NSAIDs and have no contraindications |
TeleDirectMD does not prescribe controlled substances, antibiotics for uncomplicated viral influenza, or unproven flu therapies. All antiviral decisions are individualized based on timing, risk factors, and potential interactions.
Home Care, Monitoring, and Return to Work
Many adults with influenza begin to feel gradual improvement over several days, though fatigue and cough can persist longer. Your TeleDirectMD physician will explain what to expect, how to monitor at home, and when to escalate care.
- Follow isolation and masking recommendations, especially around high-risk individuals
- Maintain hydration and nutrition as tolerated, and rest during the acute phase
- Use recommended over-the-counter medications safely for symptom relief
- Monitor for worsening shortness of breath, chest pain, confusion, or signs of dehydration and seek urgent care if they appear
- Discuss timing of return to work based on symptom improvement, workplace policies, and your job’s exposure risk
- Arrange follow-up with your usual clinician if symptoms are prolonged or complications are suspected
Many adults can return to work once fever has resolved without fever-reducing medications, overall symptoms are improving, and they feel well enough to perform their duties, while following current public health and workplace guidance.

Frequently Asked Questions about Online Flu Treatment
For adults with mild to moderate symptoms who can speak in full sentences and are not in distress, telehealth is well suited for evaluation, risk assessment, and home care planning. TeleDirectMD physicians identify red flags that require urgent in-person or emergency care instead of virtual-only management.
Influenza often starts abruptly with higher fever, severe body aches, and fatigue, while colds tend to be milder and more focused on congestion. COVID-19 can overlap with both. Your TeleDirectMD physician uses your symptom pattern, timing, exposure history, vaccination status, and available test results to guide the diagnosis and management plan.
No. Many lower-risk adults recover fully with supportive care alone. Oseltamivir is generally reserved for adults at higher risk for complications or with significant symptoms, especially when started early in the illness. TeleDirectMD helps determine whether you are likely to benefit from antiviral therapy.
Antivirals work best when started early in the illness course. If you are older or have chronic medical conditions that increase your risk, you should arrange evaluation as soon as possible after symptom onset so that a TeleDirectMD physician can decide whether oseltamivir is appropriate within the recommended treatment window.
Oseltamivir can cause side effects such as nausea, vomiting, and headache in some adults. TeleDirectMD physicians review your medical history and medications, explain potential side effects, and help you weigh the expected benefits and risks before prescribing.
TeleDirectMD does not prescribe antibiotics for uncomplicated viral influenza, and steroid use is not appropriate for most mild outpatient flu cases based on current evidence. Your physician will explain when additional treatments are indicated and when they are more harmful than helpful.
Severe shortness of breath, chest pain, confusion, very low oxygen readings, inability to keep fluids down, or rapid worsening in a high-risk adult are all reasons to seek emergency care immediately. During your telehealth visit, TeleDirectMD physicians emphasize these red flags and direct you to in-person or ER care whenever virtual-only management is not safe.
Many adults feel significantly ill for several days, with fatigue and cough sometimes lasting longer. TeleDirectMD physicians discuss typical recovery timelines and help you decide when it is reasonable to return to work, considering symptom improvement, job duties, and workplace policies, while following current public health guidance.
Staying hydrated, resting, using appropriate fever reducers and pain relievers, and monitoring for red flags are key. High-risk adults should be especially vigilant. TeleDirectMD physicians reinforce home safety steps and when to transition from virtual to in-person care if symptoms worsen or do not follow a typical recovery pattern.
TeleDirectMD is MD-only, uses a flat $49 fee, and operates in 25+ states with a focus on evidence-based care and antiviral stewardship. Every visit is with a board-certified physician who clearly explains when telehealth is appropriate, when oseltamivir is indicated, and when in-person or emergency care is safer.
