5 Alternatives to Augmentin: What Else Treats Tough Infections?
April 22, 2025 posted by Arabella Simmons
Ever get handed a prescription for Augmentin, only to find out you can’t take it—or it just isn’t working? You’re not alone. Augmentin is popular because it covers a lot of bacteria, but it’s definitely not always the best or only option. There are times when doctors need to reach for something different, whether because of allergies, resistance, or other health concerns.
The good news? There’s more than one way to skin a cat—or in this case, to fight an infection. Whether you have a bad sinus infection, complicated UTI, or a tough pneumonia, there are solid alternatives out there that get the job done, sometimes with some extra features (and risks) you might not expect. Let’s take a look at what your doctor might prescribe instead, starting with Levofloxacin and moving through some practical options you might hear about. As always, this isn’t medical advice—think of it as your starting point for asking smart questions at your next appointment.
Levofloxacin (Levaquin)
If you can't take Augmentin or it just isn't strong enough, your doctor might talk about Levofloxacin, which you’ll see branded as Levaquin. This antibiotic is part of the fluoroquinolone group, and it's a favorite pick for some really stubborn or complicated infections—think bad pneumonia, tough urinary tract infections (UTIs), or infections picked up in the hospital that simply don’t budge with basic meds.
What sets Levofloxacin apart? It has super broad coverage, including some bacteria that shrug off other drugs, like Pseudomonas aeruginosa. Hospitals often pull this one out when they need serious muscle against resistant germs. You’ll see it used as both oral tablets and IV, depending on how sick someone is and how fast the meds need to work.
Pros
- Broad-spectrum activity—it’ll cover bacteria even when others can't.
- Comes as both a pill and an IV infusion, so it works for mild and severe cases.
- Trusted for complicated hospital infections and serious respiratory bugs.
Cons
- Higher risk for some scary side effects, like tendon rupture (especially in older adults or if you're on steroids) and nerve pain that can stick around.
- Can mess with your heart's rhythm—specifically, it can cause something called QT prolongation, raising the risk of arrhythmias.
- Doctors avoid it in kids, pregnant women, and people with certain heart problems, unless there's just no other choice.
Quick tip: It’s very important to drink plenty of fluids if you’re prescribed Levofloxacin, and let your doctor know if you start feeling pain in your joints, tingling, or irregular heartbeats. Studies say fluoroquinolones are linked with more ER visits for tendon problems than most antibiotics—so don’t ignore aches and pains.
| Condition | Augmentin | Levofloxacin |
|---|---|---|
| Sinus Infections | First choice | If Augmentin fails or can't be used |
| UTIs | Sometimes (not first-line for complicated cases) | Complicated/resistant cases |
| Pneumonia | Community-acquired mild/moderate cases | Severe cases, hospital-acquired, or resistance suspected |
Amoxicillin
If you’re looking for something that hits a lot of the same bacteria as Augmentin alternatives but with fewer frills, amoxicillin is usually the go-to. It’s basically the bread and butter of the antibiotic world. Amoxicillin treats things like strep throat, ear infections, and basic sinus infections but skips the "clavulanate" piece that lets Augmentin tackle some tougher bugs. It’s pretty gentle on the gut for most people and is safe for kids and adults, so doctors prescribe it all the time.
Fun fact: In the last CDC annual report, amoxicillin ranked as one of the most prescribed antibiotics in U.S. outpatient settings. It’s usually taken by mouth, but if you can’t swallow pills, liquid versions are widely available.
Pros
- Effective against many common ear, nose, and throat bacteria
- Often cheaper and easier on your stomach than Augmentin
- Safe for use in children, pregnant women, and breastfeeding moms
- Comes in lots of dosage forms, including chewables and liquids
Cons
- Won’t work if the bacteria makes an enzyme called beta-lactamase
- Not great for more serious infections or hospital-acquired bugs
- Can trigger allergies, especially if you’re sensitive to penicillin
- Some resistance in sinus and ear infections, depending on your area
| Dosage Forms | Common Uses | Main Side Effects |
|---|---|---|
| Tablets, capsules, liquid | Strep throat, ear infections, sinusitis | Rash, diarrhea, allergic reactions |
If money’s tight or you want to avoid unnecessary side effects, amoxicillin might be your best bet—just double check with your healthcare provider that it’ll do the trick for your bug.
Cefuroxime
If you’re looking for an option that’s a bit different from Augmentin but still covers a decent spread of bacteria, cefuroxime is worth a look. It’s part of a group called second-generation cephalosporins, and doctors use it when they need something a little tougher than standard amoxicillin. People reach for this antibiotic for things like sinus infections, ear infections, and even some mild cases of pneumonia or skin infections.
It works well on many common bacteria responsible for respiratory tract and urinary tract infections. Unlike some antibiotics, cefuroxime usually doesn’t get knocked out easily by beta-lactamase, which is an enzyme certain bacteria use to resist drugs like amoxicillin. That’s a practical reason it pops up as an alternative to Augmentin—especially if you can’t handle the side effects tied to clavulanic acid (the thing in Augmentin that often upsets people’s stomachs).
Pros
- Comes in both oral tablets and injectable forms, so it works for different levels of infection.
- Usually well-tolerated and doesn’t mess much with your gut or liver.
- Effective against several bacteria that have become resistant to amoxicillin alone.
- Less likely than Augmentin to cause diarrhea or stomach upset in most adults.
Cons
- Not great against some bacteria that produce certain tough enzymes (like ESBL, which is a problem in hospitals).
- Possible allergic cross-reaction if you’re allergic to penicillins (though it’s not super common, it’s a real concern).
- Needs to be taken exactly as prescribed—you can’t skip doses or you risk the infection coming back.
- Limited action on some of the really serious hospital bugs, so not for everyone.
Here’s a quick comparison so you get an idea of how cefuroxime stacks up compared to Augmentin:
| Cefuroxime | Augmentin | |
|---|---|---|
| Form | Oral & IV | Oral & IV |
| Common uses | Sinus, ear, skin, UTI | Sinus, lung, skin, dental |
| Stomach side effects | Lower risk | Higher risk (from clavulanate) |
| Bacterial resistance coverage | Moderate | Higher (with clavulanate) |
What makes cefuroxime handy is it bridges the gap between simple antibiotics and really heavy-duty ones. If you’ve got a standard infection and want to avoid some of Augmentin’s drawbacks, it could be just what the doctor orders. Always talk things over with your provider, since allergies and infection type make a big difference here.
Clindamycin
When Augmentin is off the table—maybe it just isn’t working or you can’t tolerate it—Clindamycin often jumps into the spotlight, especially for skin and soft tissue infections. It’s also a go-to for certain dental infections and can tackle tough bugs like MRSA. In some cases, it’s the first pick if patients have a penicillin allergy, making it a pretty flexible choice in the alternatives toolbox.
Clindamycin gets prescribed in both pill and IV form, covering a wide range of bacteria, from strep and staph to some pesky anaerobes that love low-oxygen environments (think deep wounds or abscesses). It won’t cover every infection—gram-negative bugs are its weak spot—but it’s hard to beat for treating abscesses or infections where mouth or gut bacteria might be involved. It’s even used with other antibiotics for serious bone or joint infections (osteomyelitis).
Pros
- Works well against gram-positive bacteria, including MRSA (methicillin-resistant Staphylococcus aureus)
- Covers anaerobic bacteria, so it’s great for dental infections and deep tissue abscesses
- Oral and IV options give doctors flexibility, especially for moving patients from the hospital to home
- Good alternative for people with serious penicillin allergies
Cons
- Clindamycin is well known for causing diarrhea—and in around 1 in 10 cases, it can lead to a serious gut infection called C. difficile
- Not effective for most infections caused by gram-negative bacteria (like E. coli)
- Overuse can drive up antibiotic resistance, so it’s generally not a first-line pick unless needed
- Some folks develop skin rashes or allergic reactions
If your doctor prescribes Clindamycin, always let them know if you have stomach problems or have had C. diff before. Staying hydrated and reporting any new watery diarrhea is key. While it’s not as broad as Augmentin, when clindamycin’s targeted to the right kind of infection, it’s super effective—and sometimes life saving.
Doxycycline
If you hear your doctor mention Doxycycline as an alternative to Augmentin, you’re definitely not alone. Doxycycline is a trusty old-timer in the world of antibiotics, and it’s got a pretty wide range. It’s most famous for tackling things like sinus infections, pneumonia, acne, some STIs, and even Lyme disease. Unlike Augmentin, which is a combination of two drugs, Doxycycline stands alone and is a favorite when someone is allergic to penicillin.
Doxycycline is part of the tetracycline family. Here’s what makes it handy: it’s taken by mouth (tablet or capsule), typically once or twice a day, and it has pretty reliable absorption even if you miss a meal. You might see it prescribed when someone has a penicillin allergy, or in cases of resistant infections where first-line drugs won’t cut it. Fun fact: the CDC lists Doxycycline as the main option for treating Lyme disease and certain tick-borne illnesses.
"Doxycycline remains an excellent choice for outpatient treatment of community-acquired respiratory infections, and has favorable activity against atypical pathogens such as Mycoplasma and Chlamydia," says Dr. Mary Stack, infectious diseases specialist at a major university hospital.
Pros
- Broad-spectrum coverage, especially for respiratory, skin, and tick-borne infections.
- Well-absorbed whether you eat or not, though taking it with food reduces stomach upset.
- Usually safe for people allergic to penicillins or cephalosporins.
- A good option for unusual infections like chlamydia, Lyme disease, and even malaria prevention.
Cons
- Not for young kids under 8 or pregnant women due to teeth and bone risks.
- Photosensitivity—makes you more likely to burn in the sun.
- Can cause stomach upset, heartburn, or trouble swallowing if not taken with water.
- Bacteria can get resistant if the drug is overused.
Just a heads up—dairy and antacids get in the way of doxycycline absorption, so you’ll want to avoid them within two hours of your dose. If you’re out hiking where Lyme disease is a risk, Doxycycline is the go-to. Meanwhile, it punches above its weight for less severe chest and skin infections when Augmentin alternatives are called for. Don’t forget to use sun protection, since even a bit of sun can make you burn while on this med.
Summary and Comparison Table
So, which Augmentin alternatives actually pull their weight? It really depends on the type of infection, your health history, and any allergies you might have. There’s no one-size-fits-all, but here’s the gist of how these antibiotics stack up against each other.
Levofloxacin can be a heavy hitter against tough bugs, especially ones that hide out in hospitals. Amoxicillin is basically the classic old-school option—it’s simple, works for a lot of common infections, and usually causes fewer stomach issues than combos like Augmentin. Cefuroxime is all about versatility, especially if you’ve got mid-level resistance or can’t tolerate penicillins. Clindamycin steps in for folks who are allergic to penicillins and need coverage for skin or dental infections. Doxycycline is the go-to for some weird (but common) stuff, like atypical pneumonia, certain tick-borne illnesses, or acne.
Here’s a quick side-by-side so you can see which medication does what:
| Alternative | Best For | Pros | Cons |
|---|---|---|---|
| Levofloxacin (Levaquin) | Complicated UTIs, pneumonia, hospital-acquired infections |
|
|
| Amoxicillin | Ear infections, sinusitis, routine respiratory infections |
|
|
| Cefuroxime | Bronchitis, Lyme disease, skin infections |
|
|
| Clindamycin | Serious dental infections, MRSA, skin/soft tissue infections |
|
|
| Doxycycline | Tick-borne illnesses, acne, atypical pneumonia |
|

Your doctor takes a look at your infection, your other health problems, and what’s worked before, then picks the best tool for the job. No matter the alternative, sticking to the dose and watching for side effects makes a real difference in getting you back on your feet. If you’re not sure why you’re getting a certain antibiotic over Augmentin, don’t be shy—ask. It’s your health, after all.
