What Is Adult Cellulitis?

Cellulitis is an acute bacterial infection of the deeper layers of the skin and soft tissue. It typically presents with an area of redness, warmth, swelling, and tenderness that may spread over hours to days. The infection often starts when bacteria enter through a break in the skin such as a cut, insect bite, ulcer, or athlete’s foot.

In otherwise healthy adults, mild localized cellulitis without systemic symptoms can sometimes be managed with oral antibiotics and close follow-up. However, rapidly spreading redness, high fever, systemic illness, or involvement of certain high-risk areas like the face, hands, or genitals requires urgent in-person evaluation and often IV antibiotics. A core role of telehealth is to distinguish which category you fall into and direct you to the safest setting for care.

Symptoms and Red Flags in Adult Cellulitis

Many adults with mild, early cellulitis can be triaged and treated through a virtual visit. Certain symptoms, however, suggest deeper infection, sepsis, or special locations that require in-person or hospital-level care instead of telehealth alone.

Symptom What it suggests Telehealth appropriate? Red flag requiring urgent in-person care
Localized redness, warmth, and tenderness of skin Typical early cellulitis or local skin infection Often appropriate if limited area and patient well-appearing Not a red flag alone if small, stable, and without systemic symptoms
Redness surrounding a small cut, scratch, or insect bite Entry site for bacteria causing mild cellulitis Yes, if area is small and not rapidly spreading Rapid expansion of redness or severe pain over a few hours
Low-grade fever with localized leg or arm infection Moderate cellulitis needing careful assessment Telehealth may be appropriate for initial evaluation High fever, rigors, or signs of sepsis
Fluctuant lump or pocket of pus (abscess) Likely abscess that may need drainage Telehealth can help diagnose and direct care Large or deep abscesses often require in-person drainage
Red streaks tracking up the limb from the infected area Possible lymphangitis and more advanced infection Telehealth may triage but is limited Associated fever, chills, or feeling very ill
Red, swollen skin on face, around eyes, or on hands or genitals Higher-risk sites with potential for serious complications Telehealth may help identify concern Orbital involvement, trouble seeing, or difficulty moving fingers
Severe pain out of proportion to skin findings Possible deeper infection such as necrotizing fasciitis No Requires emergency department evaluation
Fever, chills, confusion, rapid heart rate, or rapid breathing Possible sepsis from skin infection No Emergency evaluation is required, not telehealth-only care
Open ulcers or wounds on a person with diabetes or poor circulation Higher risk of deep infection, osteomyelitis, or poor healing Telehealth may triage but cannot fully evaluate Deep ulcers, foul odor, or inability to bear weight

Differential Diagnosis: Cellulitis vs Other Red, Swollen Skin Conditions

Not every red, warm area on the skin is true cellulitis. During your TeleDirectMD visit, the MD will assess onset, location, pain, systemic symptoms, and any trauma or bites to differentiate uncomplicated cellulitis from other conditions that may require different treatment or in-person testing.

Typical Cellulitis

  • Ill-defined redness, warmth, swelling, and tenderness in 1 region
  • Often follows a break in the skin, athlete’s foot, or bite
  • May cause low-grade fever and feeling unwell
  • Improves with appropriate antibiotics and limb elevation

Other Conditions That Mimic Cellulitis

  • Stasis dermatitis: Chronic reddish-brown changes and swelling in lower legs from venous disease, usually less tender and more long-standing.
  • Contact dermatitis: Itchy rash with clear trigger such as new cream or bandage; often sharply demarcated and less painful.
  • Gout or inflammatory arthritis: Red, hot, swollen joint with intense pain, often at big toe, ankle, or knee.
  • Deep vein thrombosis (DVT): Swollen, painful limb with risk factors for clot; may have minimal skin redness but requires urgent imaging.

Telehealth can often distinguish these based on detailed history and photos. When the diagnosis is uncertain, the area is extensive, or systemic symptoms are present, in-person evaluation is recommended both to confirm the cause and to choose the safest treatment setting.

When Is a Video Visit Appropriate for Cellulitis?

When a Video Visit Is Appropriate

  • Localized redness and warmth of a small area of skin
  • Mild to moderate pain that is manageable without strong narcotics
  • No high fever, chills, or confusion
  • No rapidly spreading redness or severe pain in the last few hours
  • No deep ulcers, exposed bone, or foul-smelling wounds
  • Patient can show the affected area clearly on camera
  • Adult 18+ who can obtain oral antibiotics and follow safety instructions

Red Flags Requiring In-Person or ER Care

  • High fever, rigors, rapid heart rate, or rapid breathing
  • Severe pain out of proportion to the appearance of the skin
  • Rapidly expanding redness or swelling over hours
  • Infection around the eye, on the face, or on the genitals
  • Deep diabetic foot ulcers, foul odor, or inability to walk
  • History of immune suppression, chemotherapy, or advanced liver or kidney disease with new infection
  • Recent surgery at the affected site with increasing pain and redness

If any red-flag symptoms are present, seek in-person or emergency care immediately. TeleDirectMD is not an emergency service and does not manage sepsis, necrotizing infections, or other life-threatening conditions by telehealth.

Treatment Options for Adult Cellulitis

Management of cellulitis focuses on early recognition, appropriate antibiotics, and supportive measures. Our MDs follow evidence-based guidelines to choose oral antibiotics when it is safe and to direct you to urgent in-person or emergency care when higher-level treatment is required.

Supportive Measures and Skin Care

  • Mark the border of redness with a pen to help track whether it is spreading.
  • Elevate the affected limb when possible to reduce swelling and discomfort.
  • Keep the area clean and dry; avoid aggressive scrubbing or home incision attempts.
  • Use over-the-counter pain relievers such as acetaminophen or ibuprofen if appropriate.
  • Monitor for worsening pain, spreading redness, fevers, or new systemic symptoms.

Antibiotic Therapy (When Appropriate)

  • For mild nonpurulent cellulitis, beta-lactam antibiotics covering streptococci are typically used first-line.
  • For purulent infections or suspected MRSA, regimens that include MRSA-active agents may be considered.
  • Antibiotic choice is adjusted based on allergy history, local resistance patterns, and comorbidities.
  • Telehealth is not appropriate for IV antibiotic initiation; those cases require in-person or hospital care.

TeleDirectMD emphasizes antibiotic stewardship: using the narrowest effective regimen at an appropriate dose and duration, avoiding unnecessary dual coverage, and clearly explaining when in-person evaluation or imaging is safer than continuing outpatient telehealth management.

Common Medications Used for Adult Cellulitis

The exact regimen is individualized based on infection location, severity, allergy history, local resistance patterns, and other medical conditions. The table below shows typical oral options your MD may consider for mild to moderate cases that are appropriate for outpatient telehealth management.

Medication Dose Duration When it is used
Cephalexin 500 mg 500 mg by mouth 4 times daily Typically 5–7 days, longer if slow response First-line for mild nonpurulent cellulitis in adults without severe beta-lactam allergy
Dicloxacillin 500 mg 500 mg by mouth 4 times daily Typically 5–7 days Alternative for nonpurulent cellulitis when penicillinase-resistant agent preferred and no allergy
Clindamycin 300 mg 300 mg by mouth 3–4 times daily Typically 5–7 days Adults with beta-lactam allergy or when MRSA and streptococcal coverage are both desired
Trimethoprim–sulfamethoxazole DS 1–2 DS tablets by mouth 2 times daily Typically 5–10 days Suspected MRSA skin infection, usually combined with a beta-lactam when streptococcal coverage is also needed
Doxycycline 100 mg 100 mg by mouth 2 times daily Typically 5–10 days Alternative MRSA-active oral agent when appropriate and no contraindications

These are example regimens only. Actual medications, doses, and durations are determined by the MD after reviewing your history, allergies, infection severity, and concurrent medications. TeleDirectMD does not prescribe IV antibiotics or controlled substances by telehealth and will refer you for in-person evaluation if your infection requires higher-level care.

Home Care, Expectations, and Return to Work

With appropriate antibiotics and supportive care, many mild cellulitis cases start to improve within 24–48 hours, although full resolution of redness and swelling can take several days. The goal is to stop progression, relieve pain, and prevent complications such as abscess, deep infection, or sepsis.

  • Take antibiotics exactly as prescribed and complete the full course, even if symptoms improve early.
  • Check the marked outline of redness at least twice daily to ensure it is not expanding.
  • Elevate the affected limb and limit excessive use until pain and swelling decrease.
  • Call for care or seek in-person evaluation if redness spreads beyond the marked line, fever develops, or pain worsens.
  • Arrange follow-up if you have diabetes, immune suppression, or recurrent cellulitis episodes.

Many adults with mild cellulitis can continue working or return to work once antibiotics are started and they feel well enough, depending on job duties and infection location. If a work note is needed, TeleDirectMD can generally provide documentation of evaluation and treatment rather than extended time off, unless there are complicating medical issues.
