Both Choice And Dose Of Antimicrobial Are Important
While there are less available data regarding the antimicrobial susceptibility of bacteria causing AOM, the penicillin susceptibility rate of S pneumoniae, which causes invasive disease, is > 90% in most jurisdictions in Canada.- Because S pneumoniae is the predominant pathogen in AOM and because it also covers GAS, empirical amoxicillin remains the drug of first choice. M catarrhalis and some strains of H influenzae are more likely to be amoxicillin-resistant but they are less common pathogens, and AOM caused by either bacteria is more likely to resolve spontaneously.
Amoxicillin has excellent middle ear penetration , is inexpensive, well tolerated and has a relatively narrow antimicrobial spectrum. It has a short half-life of approximately 1 h. Given in an adequate oral dose, amoxicillin is more likely than other oral antimicrobials to be effective against penicillin-susceptible and some penicillin-resistant S pneumoniae, beta-lactamase-negative H influenzae and GAS. For clinical cure of AOM, the levels of amoxicillin in the middle ear should be adequate for over 50% of the day. Administering 45 mg/kg/day to 60 mg/kg/day of amoxicillin in three divided doses will achieve adequate middle ear levels, whereas a twice per day dosing regimen requires higher total daily doses of 75 mg/kg/day to 90 mg/kg/day to maintain adequate levels for a comparable percentage of the day .

Interpreting The Recommendations Of The Cdc Working Group
According to the CDC report, amoxicillin remains the initial drug of choice for the treatment of acute otitis media. Higher dosages of amoxicillin are recommended to address the issue of penicillin-resistant pneumococci.25 The increased dosage produces higher levels of amoxicillin in middle ear fluid.26 However, regardless of the dosage, amoxicillin will not eradicate beta-lactamaseproducing H. influenzae or M. catarrhalis. For this reason, alternatives to amoxicillin should ideally be effective against these beta-lactamaseproducing pathogens.
The CDC recommendations include the possibility of performing tympanocentesis in selected cases to guide management of refractory acute otitis media. Few family physicians, however, perform this procedure. Otolaryngologists are infrequently available to accommodate a same-day referral for the procedure, and still fewer have done it without the benefit of general anesthesia.

Drug Interactions Of Amoxicillin Vs Augmentin
Amoxicillin and Augmentin can interact with other medications, including probenecid and allopurinol. Probenecid can decrease the clearance of amoxicillin and cause increased blood concentrations of amoxicillin, which may lead to increased side effects of amoxicillin. Combining allopurinol with amoxicillin or Augmentin can increase the risk of a skin rash.
Taking amoxicillin or Augmentin with anticoagulants like warfarin may increase the risk of bleeding. The dosage of anticoagulants may need to be adjusted during treatment with amoxicillin or Augmentin.
Amoxicillin and Augmentin can affect the gut flora and reduce the reabsorption of estrogen. The use of these antibiotics may decrease the effectiveness of oral birth control pills that contain estrogen or progesterone.
This may not be a complete list of all possible drug interactions. Consult a doctor with all medications you may be taking.

Amoxicillin Dosage Chart Based On The Childs Weight/ Age
The dosage could vary depending on the condition and its severity. Given below is the list of recommended amoxicillin dosages for kids:
|Children â¥ 40kg and more than 5 years||500mg to 1g in every 8 hours|
|Children < 40kg aged two months to 5 years||20 to 90mg/kg/day in divided doses|
Amoxicillin clavulanate potassium combination is used in the lowest dose to bring down the adverse gastrointestinal drug effects. It is available in the form of suspension, chewable tablet, and tablet. The clavulanic acid in amoxicillin and clavulanate potassium formulation prevents amoxicillin degradation by Î²-lactamase enzymes. This extends the antibiotic spectrum of amoxicillin to many bacteria that are normally resistant to the drug.
- The average dosage is 30mg/ kg of the childâs weight/ day.
- Children above three months of age weighing up to 40kg â 25-45mg/kg/day, divided and given every 12 hours. For this age group usually, a suspension or chewable tablet is prescribed due to the clavulanic acid component.
- Children weighing more than 40kg â 500-875mg, divided and given every 12 hours. Usually, a tablet is prescribed.
Once the child starts taking medicine, she should be feeling better by the second day.
The above dosages are a broad standard and they may or may not be suitable for all children.
Note: If your child vomits within 30 minutes of taking medicine, then give the same dose again. You donât have to repeat the dose if she vomits after 30 minutes.

Management In The Setting Of Diagnostic Uncertainty
In reality, the clinician often faces a dilemma with children in whom the TM cannot be properly assessed. For many reasons clinicians may not be able to determine conclusively whether the TM is bulging. In these common situations, the differential diagnosis may still include viral illness affecting the upper respiratory tract with an associated OME, a systemic viral illness or an AOM that could resolve on its own. Using antimicrobials in these situations may not always be the most prudent course of action.
If the child is only mildly ill, does not appear to have severe otalgia, is still feeding reasonably well, has a temperature < 39°C for < 24 h and reliable caregivers, it is still reasonable to observe, and have child and caregiver return for follow-up the next day. The focus of reassessment is the evolution of the TM or the development of other symptoms or signs. As in the watchful waiting scenario for a confirmed AOM, explanations regarding the management plan should be discussed with caregivers so decision-making can be shared. Again, it is vital to provide appropriate advice about analgesics.

Oral Amoxicillin/clavulanate For Community Utis
In the case of uncomplicated and moderate urinary tract infections in the community, the empirical oral antibiotics nitrofurantoin, trimethoprim/sulfamethoxazole, fosfomycin, pivmecillinam, fluoroquinolones as well as amoxicillin/clavulanate and oral cephalosporins are prescribed. A susceptibility study for 2017 SENTRY surveillance of E. coli isolates collected from US patients with UTI showed 77.9% susceptibility to amoxicillin/clavulanate . More published studies also point towards contemporary UTI-causing Enterobacterales showing reduced susceptibility to amoxicillin/clavulanate . This phenomenon is part of the larger trend of rising prevalence of extended spectrum beta-lactamases coupled with OXA-1. Moreover, TEM-1 hyperproduction has also been implicated in resistance to amoxicillin/clavulanate . It should be also noted that, as a result of systemic metabolism, urinary concentrations of clavulanate could be low at the recommended oral dose of 125 mg. Furthermore, no PK/PD data is available to support that the detected urinary levels of clavulanate are adequate to restore the amoxicillin activity against ESBL isolates. All these observations need to be considered regarding the current utility of orally administered amoxicillin/clavulanate for the treatment of community UTI infections that do not require hospitalization .

How Does Amoxicillin Work
After starting therapy, amoxicillin will begin to work faster than many other antibiotics since it is “bactericidal“, which means it kills bacteria. This is in contrast to “bacteriostatic” antibiotics, which slow the growth and reproduction of bacteria but don’t kill them directly.
Specifically, amoxicillin works by inhibiting bacterial cell wall synthesis by binding to what is known as penicillin-binding proteins . These are located inside the bacterial cell wall.
Amoxicillin’s ability to interfere with PBPs in the cell wall ultimately leads to cell lysis .

Side Effects Of Amoxicillin For Cats
The side effects of amoxicillin are usually mild and infrequent, involving gastrointestinal upset like vomiting and diarrhea.
Oral amoxicillin, like many broad-spectrum antibiotics, can alter the normal, beneficial bacteria in the digestive tract, which is often a cause of digestive upset if it occurs.
Giving amoxicillin to your kitty around the time of a meal can help to offset these possible effects. If side effects like these continue, its important to ask your vet for further advice.
While discontinuing an antibiotic may relieve the side effects, this will also leave the original bacterial infection untreated. If your kitty is dealing with a very concerning infection, your vet may, for example, recommend starting a probiotic as opposed to discontinuing an antibiotic.

Severe allergic reactions to amoxicillin are extremely rare but can include rashes, hives, fever, and changes to red and white blood cell counts. To the rare kitty this might happen with, these effects would occur with even a very small dose. In other words, if your kitty is doing well at a prescribed dose, an accidental extra dose or overdose would not cause these effects.
Some Side Effects Can Be Serious If You Experience Any Of The Following Symptoms Call Your Doctor Immediately:
- severe skin rash
- vaginal itching and discharge
- yellowing of the skin or eyes
Amoxicillin and clavulanic acid may cause other side effects. Call your doctor if you have any unusual problems while taking this medication.
If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration’s MedWatch Adverse Event Reporting program online or by phone .
