Iâve had nosebleeds, nasal congestion for over a month â no other symptoms. This dose immediately kicked up my acid reflux so I started prilosec. Should I take this much Amoxicillin or drop it down to half the dose? Dr wants me to take this for 14 days.

I suggest you give your Dr. a call and explain the situation to him / her, you have had nosebleeds and reflux, so I do not think it is a good idea to self medicate, I would take less Amoxicillin, but I am not a Dr. and I can give you my opinion but the final word is for the Dr. to say, and I believe you do need a dose adjustment and your Dr. will lower the dose. And do not forget to tell him what happened when you took more of this antibiotic.

All the best,


I agree you should definatly consult the dr before lower the dose but that does seem like alot of antibitic. but it also seems like an awful bad sinus infection Iâm wondering does your dr no you are having the nose bleeds? are they really bad or just a little? If they are from the dry and congestion and only when blowing your nose I would put a few drp of saline in your nose to cut down the stuffiness s you can greth sold at any store in drps or spray even just warm water helps I really hope yu feel better soon!

What If You Don’t Start To Feel Better


Most studies, such as the guidelines to treat ear infections in children, recommend that if no clinical improvement is seen within 48-72 hours of starting amoxicillin, therapy should be reevaluated.

Similarly, the American Academy of Pediatrics guidelines for the treatment of sinusitis states the following:

“Amoxicillin with or without clavulanate is the firstline treatment of acute bacterial sinusitis. Clinicians should reassess initial management if there is either a caregiver report of worsening or failure to improve within 72 hours of initial management.”

So overall, amoxicillin is absorbed quickly after taking a dose by mouth, and you should feel improvement in your symptoms within 72 hours. If you do not, it is important to speak with your doctor as your infection may be resistant to the antibiotic, and alternative therapy options should be considered.

Alternative therapies include:

Pathogenesis Of Acute Sinusitis

Acute sinusitis usually follows an acute upper respiratory tract infection . As the viral infection spreads in the nasal mucosa, swelling and oedema of the mucosa results. As the mucosal surfaces of the ostiomeatal unit are in close proximity to one another , obstruction of the sinus ostia results. In addition, the viral infection may reduce normal cilial motility. This prevents normal muco-ciliary clearance resulting in an accumulation of mucus in the sinuses and the development of the symptoms of sinusitis. If this mucus becomes secondarily infected by bacteria, acute bacterial sinusitis develops.

Is It Possible To Prevent Sinus Infections Or Sinusitis

Treatment for sinus infections

Currently, there are no vaccines designed specifically against infectious sinusitis or sinus infections. However, there are vaccines against viruses and bacteria that may cause some infectious sinusitis. Vaccination against pathogens known to cause infectious sinusitis may indirectly reduce or prevent the chance of getting the disease however, no specific studies support this assumption. Fungal vaccines against sinusitis are not available, currently.

If you are prone to recurrent bouts of a “yearly sinus infection” it may be important to consider allergy testing to see if this is the underlying cause of the recurring problem. Treatment of the allergy may prevent secondary bacterial sinus infections. In addition, sinus infections may be due to other problems such as nasal polyps, tumors, or diseases that obstruct normal mucus flow. Treatment of these underlying causes may prevent recurrent sinus infections.

Most Sinus Infections Dont Require Antibiotics

Amoxicillin dosing for sinus infection, how much amoxicillin for sinus ...

Ah, sinus infections. The New England Journal of Medicine published a clinical practice review of acute sinus infections in adults, that is, sinus infections of up to four weeks. The need for an updated review was likely spurred by the disconcerting fact that while the vast majority of acute sinus infections will improve or even clear on their own without antibiotics within one to two weeks, most end up being treated with antibiotics.

It is this discrepancy that has clinical researchers and public health folks jumping up and down in alarm, because more unnecessary prescriptions for antibiotics mean more side effects and higher bacterial resistance rates. But on the other hand, while 85% of sinus infections improve or clear on their own, theres the 15% that do not. Potential complications are rare, but serious, and include brain infections, even abscesses.

What Interacts With Amoxicillin

Amoxicillin may cause problems when combined with other prescription drugs:

  • Amoxicillin may reduce the effectiveness of birth control pills. Women taking oral contraceptives may be advised to use additional birth control while on antibiotics.

  • When taken with blood-thinning drugs, amoxicillin increases the amount of time required to form blood clots, which can lead to an increased risk of bleeding. Anticoagulant doses may need to be adjusted.

  • Amoxicillin can reduce the effectiveness of live bacterial vaccines, such as typhoid vaccine or BCG .

  • When the gout medication allopurinol is taken with amoxicillin or ampicillin, there may be an increased risk of rash or more serious hypersensitivity reactions involving internal organs.

Not all amoxicillin drug interactions are bad. Probenecid, another drug used to treat gout, actually increases the effectiveness of amoxicillin. Some people may be prescribed both drugs for certain types of infections. An aminoglycoside may also be used with amoxicillin for increased effectiveness of both drugs.

Experts Update Best Practices For Treating The 1 In 8 Us Adults Suffering From Sinusitis

Pin by Elizabeth M :) on school in 2020
  • Sinusitis affects about 1 in 8 adults in the United States, resulting in over 30 million annual diagnoses. The direct cost of managing acute and chronic sinusitis exceeds $11 billion per year.
  • More than 1 in 5 antibiotics prescribed in adults are for sinusitis, making it the fifth most common diagnosis responsible for antibiotic therapy.
  • Because sinusitis is treated differently based on its cause, it is critical to differentiate between acute viral sinusitis and acute bacterial sinusitis.
  • New evidence supports a recommendation of either watchful waiting or antibiotic therapy for mild, moderate, or even severe acute bacterial sinusitis.

ALEXANDRIA, VA An updated clinical practice guideline from the American Academy of OtolaryngologyHead and Neck Surgery Foundation published today in OtolaryngologyHead and Neck Surgery identifies quality improvement opportunities and explicit actionable recommendations for clinicians managing adult sinusitis, including a greater focus on patient education and patient preference.

More than ever before, there is a prominent role for shared decision-making between patients and clinicians when managing adult sinusitisespecially in deciding whether to use antibiotics for acute bacterial sinusitis or to instead try watchful waiting to see if a patient can fight the infection on his or her own.
