Sinusitis Treatment (antibiotic as prescribed)
Prescription — short oral antibiotic course, only where a provider judges the infection bacterial
Most sinus infections are viral and clear on their own; a bacterial one that fits the guideline pattern gets a short antibiotic course. A provider decides which yours is, and sends any prescription to a local pharmacy.
FDA-approved for acute bacterial sinusitis or related respiratory tract infections — amoxicillin-clavulanate, amoxicillin, cefdinir, doxycycline and levofloxacin each carry such an indication on their labels. Prescribed by a licensed provider only if appropriate for you.

Questions
Will I definitely be prescribed this?
No. A consultation does not guarantee a prescription — and with sinusitis, the provider's first job is deciding whether an antibiotic is warranted at all. Most sinus infections are viral and guidelines ask providers to reserve antibiotics for the bacterial pattern, so a recommendation of saline rinses, a decongestant and time is a real outcome of this visit. If prescribed, the prescription is sent to a local pharmacy and you pay for the medication there; what you pay here is the consultation, whether or not a prescription follows.
I've had this for five days and the discharge is green — isn't that bacterial?
Not on its own. Coloured discharge is white blood cells doing their job and is common in viral sinusitis. The guideline signals are duration past ten days without improvement, a severe onset with high fever, or the improve-then-worsen pattern — the provider weighs those, not the colour.
Why not levofloxacin, since it's a strong antibiotic?
Because FDA has asked that fluoroquinolones be kept out of acute sinusitis wherever another option exists — their side effects can be disabling and permanent — and the guidelines name amoxicillin-clavulanate first. A provider who chooses the narrower drug is following that evidence.
How it works
The sinuses are air pockets in the skull that drain into the nose through narrow openings. A cold swells that lining, the openings close, mucus pools, and pressure and congestion follow — that is sinusitis, and in the great majority of adults it is viral and settles within ten days without an antibiotic. Bacteria take advantage of the blocked, stagnant sinus in a minority of cases, and the guidelines describe the pattern that suggests it: symptoms that last ten days or more without improving, a severe start with high fever and thick discharge for three or four days, or a cold that improves and then clearly worsens. Where that pattern is present, amoxicillin-clavulanate is the usual first choice — amoxicillin breaks the bacterial cell wall while clavulanate disables the enzyme that some sinus bacteria use to destroy it. Cefdinir works on the cell wall by a related route for mild penicillin allergy; doxycycline binds the bacterial ribosome and halts protein synthesis; levofloxacin blocks the enzyme that unwinds bacterial DNA and is held in reserve because of its warnings. Whichever is chosen, the provider's first decision is whether an antibiotic belongs in your plan at all, and watchful waiting with saline rinses and decongestion is a legitimate answer the guidelines endorse.
The full mechanismA provider may consider it if
- Facial pressure, thick nasal discharge and congestion that have lasted ten days or more without improving
- A cold that got better and then came back worse, with fever and one-sided facial pain
- You want a provider to say honestly whether this is bacterial — and to hold the antibiotic if it is not
It won’t be prescribed if
- Severe headache with a stiff neck, confusion, swelling or redness around an eye, double or reduced vision, or a fever over 103°F — call 911 or go to an emergency department; infection spreading from the sinus to the eye or brain is rare but a true emergency
- Symptoms lasting more than four weeks, or four or more sinus infections a year — chronic or recurrent sinusitis needs an ENT examination, not another antibiotic
- A weakened immune system, poorly controlled diabetes, or recent sinus surgery — the infection is treated as complicated and belongs in person
- A known allergy to penicillins, cephalosporins, tetracyclines or fluoroquinolones — a hard stop for that medication; a severe penicillin allergy narrows the options
- Pregnancy or breastfeeding — doxycycline and levofloxacin are excluded and the provider needs to know before choosing anything
- Under 18 — online treatment here is for adults
These are the same checks your provider runs in the visit. If one applies, they will tell you plainly — and the medication portion of what you paid comes back automatically.
What to expect
After your visit
If prescribed, the prescription is sent to a local pharmacy you choose and you pay for the medication at the counter. What you paid here covers the consultation — whether the provider prescribes an antibiotic or recommends saline rinses, decongestion and time.
Days 1–3
Facial pressure and discharge usually begin to ease within a few days of a warranted antibiotic. Take doxycycline upright with a full glass of water and expect to burn faster in the sun; take amoxicillin-clavulanate with food.
If it is not settling
No improvement after three to five days, worsening pain, or any of the red flags above means in-person care — a different antibiotic by video is not the answer.
Safety
Side effects, before you decide
Amoxicillin-clavulanate: diarrhoea is the common one, plus nausea and rash; a serious allergic reaction — hives, facial swelling, wheeze — is an emergency. Cefdinir: diarrhoea and, harmlessly, reddish stools with iron-containing foods. Doxycycline: nausea, an exaggerated sunburn reaction, and irritation of the oesophagus if taken lying down; not in pregnancy. Levofloxacin: tendon pain or rupture, nerve tingling, agitation or confusion, blood-sugar swings, and a rare risk of aortic damage — the reasons it is a last resort. Any antibiotic can cause Clostridioides difficile diarrhoea during or weeks after the course.
