Sinusitis is an inflammation of the paranasal sinuses, which develops as a result of untreated runny nose and the presence of a bacterial infection in the body. Individually selected treatment of sinusitis with amoxicillin guarantees a quick recovery and no negative consequences for the patient’s health. It is very important to start treatment in a timely manner and follow all the specialist’s recommendations. If you notice the following symptoms, you should immediately seek qualified medical help:

  • the sense of smell has become noticeably lower or has completely disappeared;
  • in the area of ​​the bridge of the nose and forehead, painful sensations periodically appear, which, if left untreated, lose their exact localization, the disease is expressed by severe migraine (the pain is so severe that even painkillers are not able to relieve it);
  • body temperature - elevated (up to 38 degrees);

It is after the discharge has ceased to be transparent and has become yellow-green that it is necessary to urgently begin treatment with antibiotics. After being examined by a doctor, he will tell you how to take amoxicillin for sinusitis and prescribe additional procedures to achieve faster results.

Amoxicillin is a semisynthetic drug that has a pronounced antibacterial effect and belongs to the group of penicillins. Thanks to this composition and special concentration of the active substance for sinusitis, amoxicillin helps to quickly and effectively destroy harmful microorganisms (they are the main cause of the development of the disease and complications).

Amoxicillin, which is available in tablet form (125, 250, 500 mg and 1g), contains:

  • amoxicillin trihydrate;
  • excipients: magnesium stearate, polyvidone, sodium starch glycolate, microcrystalline cellulose.

Most often, the drug is packaged in glass or plastic jars, as well as blisters (8 and 10 tablets each). The composition of the granules (for the preparation of suspensions for oral administration, dosage 125 and 250 mg) is slightly different:

  • amoxicillin (in trihydrate form);
  • excipients: sodium saccharinate, simethicone S 184, guar gum, sodium benzoate, sodium citrate, sucrose, passionflower flavor, raspberry flavor, strawberry flavor.

Granules are produced in bottles (40 ml, 60 ml, 100 ml) with a special measuring spoon. This is the most convenient form for treating children; it also has a pleasant fruity smell and sweet taste. Thanks to the presence of simethicone, unpleasant consequences such as colic and bloating were prevented.

For those who prefer capsules, manufacturers have begun to produce a capsule form (dosage 250 and 500 mg). Available in blisters packed in cardboard boxes. Additional components include gelatin (capsule), titanium dioxide, quinoline dye and indigo carmine for the cap. Regardless of the chosen form of release, you should definitely consult with your doctor about how to take amoxicillin for sinusitis.

Description of the drug Amoxicillin and its use for sinusitis

Sinusitis, or maxillary sinusitis, is an inflammation of the paranasal sinuses as a result of an untreated runny nose, which is accompanied by a bacterial infection.

Sinusitis is an inflammation of the maxillary sinuses with the accumulation of purulent contents in them

In the initial stage, it manifests itself with the following symptoms:

  • decreased sense of smell up to its complete loss;
  • pain in the area of ​​the bridge of the nose, cheekbones and temples, which with further development of the disease lose their clear localization (the head begins to hurt);
  • increased body temperature (on average up to 38 degrees, but sometimes higher);
  • nasal discharge from mucous to purulent.

When nasal discharge ceases to be clear and begins to acquire a yellow-green tint, it is necessary to urgently begin antibacterial therapy to avoid serious complications.

Amoxicillin is quite often prescribed for the treatment of sinusitis.

The drug Amoxicycline is used quite successfully in the treatment of sinusitis. It is a semisynthetic penicillin antibiotic with a broad spectrum of action. Effective in eliminating infections caused by aerobic gram-positive (streptococci and staphylococci) and gram-negative (escherichia, shigella, klebsiella, salmonella, gonococci, meningococci, proteus, hemophilus influenzae, helicobacter bacteria) microorganisms.

The drug does not stop the proliferation of bacteria, as many other popular antibacterial agents do, but has a destructive effect on the cell membrane, thereby causing lysis (disintegration) of microbes.

pharmachologic effect

Amoxicillin for sinusitis has a pronounced bactericidal and broad-spectrum antibacterial effect. Thanks to its unique composition, the drug inhibits transpeptidase and also promotes disruption of peptidoglycan division, which is the main cause of lysis of harmful microorganisms.

The instructions for amoxicillin also indicate that the drug has a wide spectrum of antimicrobial action. It is highly active against aerobic gram-positive microorganisms, but is not able to affect the lysis of indole-positive strains of Proteus.

When taken in the form of suspensions and capsules, it is quickly absorbed and has increased stability to an acidic environment. Thanks to this, food intake cannot in any way affect the quality of absorption.

How does antibacterial medicine work?

Amoxicillin, or as it is also called in the pharmacy chain, Flemoxin for sinusitis, promotes the rapid destruction of bacterial cell walls, causing the complete death of bacteria. It is susceptible to a wide range of pathological bacteria that cause not only sinusitis, but also other serious diseases. In an acidic environment, the drug shows a certain stability and has a minimum of side effects. The semi-synthetic antibiotic belongs to the group of penicillins and also eliminates the symptoms of otitis, pharyngitis, and other sinusitis with purulent lesions of the mucous membrane. Analogs of this medicine are:

  • Amosin;
  • Lincomycin;
  • Amoxicar;
  • Ospamox;
  • Amoxilav.

Release forms

One of the advantages of Amoxicillin is its several release forms, which will allow the doctor to choose the most effective treatment option for each patient. In most cases, it is the specialist who determines the form of the drug, but in rare cases the choice is given to the patient.

Regardless of the form, the main active ingredient of the drug is the same - amoxicillin trihydrate, and they differ from each other in the type and concentration of auxiliary components. It is currently available for sale in three forms:

  • pills;
  • capsules;
  • granules.

The remaining forms are used exclusively in veterinary medicine. At the same time, the dosage of Amoxicillin for sinusitis is selected individually for each patient, which allows for faster and more noticeable treatment results.

How to take for various forms of sinusitis

Before you start treating sinusitis with amoxicillin, you should carefully read the instructions and consult your family doctor. This approach will allow you to achieve faster results and prevent serious complications. For children, the dose is calculated individually and depends on their body weight.

The drug in tablet or capsule form does not require breaking; it just needs to be swallowed and washed down with water. The granules should first be diluted in water to prepare a suspension (it is better to find out the proportions of the drug and water from the instructions, since the concentration of the main active ingredient can be completely different from different manufacturers). In this case, it is advisable to use boiled water, pouring it inside the bottle. After achieving a homogeneous liquid, you need to drink the medicine. The shelf life of the prepared solution should not exceed 14 days, and the temperature should not exceed 25 degrees Celsius. Additionally, it is recommended to shake the suspension thoroughly before each dose to prevent the active components of the drug from settling into sediment and reducing their concentration in the bulk of the liquid.

It is important to remember that amoxicillin will help with sinusitis only in cases where its dosage was selected correctly. This is why you should not self-medicate, since only a highly qualified specialist can choose the most effective dosage for you! As a result of improper treatment, negative consequences and allergic reactions may occur.

Also, the effectiveness of antibiotic use largely depends on the quality of additional physiotherapeutic procedures, which are prescribed individually for each patient. For adults, the antibiotic dosage per day is 1500 mg, which should be divided into 3 separate doses. The absorption of the drug does not depend on food intake, but it is still better not to take it on an empty stomach in order to minimize the negative effect on the stomach. The dosage of amoxicillin in the treatment of sinusitis in adults is determined individually for each person.

Description of the drug

A broad-spectrum antibacterial drug that actively affects gram-positive and gram-negative microorganisms. Regular use of Amoxicillin leads to the destruction of microbes as a result of disruption of protein synthesis. But not all microorganisms are sensitive to this drug. Some of them secrete special enzymes that destroy the active substances of Amoxicillin.


Sinusitis is far from the only disease for which doctors prescribe Amoxicillin. It is also effective in the treatment of pharyngitis, otitis, acute sinusitis and other otorhinolaryngological infections.

Use of the drug in children

Does amoxicillin help with sinusitis in children? Experts recommend using this particular antibiotic for rapid treatment of children of different ages without negative consequences. In this case, the dosage of the drug should be selected individually by the doctor:

  • children 2-5 years old. For young children, experts prescribe suspensions that have a pleasant smell and taste. In this case, the daily dose of the drug should not exceed 375 mg, and should be taken 3 times a day;
  • children 5-10 years old. The drug is taken in tablet form (250 mg) 3 times a day, the interval between doses is 8 hours. In this case, the full course of treatment lasts no more than 7 days, which is quite enough to assess the effectiveness of the chosen treatment. If there are positive dynamics, the duration of treatment can be increased to 12 days;
  • children from 10 years old. In this case, the daily dosage of the drug is 1500 mg, which is divided into 3 doses.

Amoxicillin for sinusitis dosage for adults

This drug for sinusitis still remains relevant today. Amoxicillin is still prescribed in the acute stage of the disease. Although currently the production of such more modern drugs as Macropen and Zitrolide has already been launched. Unlike Amoxicillin, they help cope with sinusitis in less than five days. However, their frequent use reduces the body's immunity, and sinusitis may appear more often. That is why this drug has become the best choice for many patients.

Principles of Amoxicillin dosage in the treatment of sinusitis

Many doctors are inclined to believe that drugs such as Ampicillin and Amoxicillin cope with the disease no worse than more modern and expensive drugs. You should also take into account the fact that the drug has been used for a long time, and its medicinal properties have been repeatedly tested and approved by patients. When treated with Amoxicillin, all symptoms of sinusitis, even the most complicated ones, can be relieved within a week. You should also remember that if pus has accumulated in your maxillary sinuses and you have not removed it, the effect of Amoxicillin will be weakened by this. And even a slight weakening of the effect of the drug can cause unrelieved swelling of the nasal sinuses.

The dosage of the drug is determined individually, taking into account the severity of the infection and the sensitivity of the pathogen.

  • Children aged 5-10 years are prescribed 0.25 g of the drug 3 times a day.
  • Dosage of the drug Amoxicillin for adults and children over 10 years of age (with body weight more than 40 kg) – 0.5 g 3 times a day.
  • In severe forms of infection, the dosage of the drug can be increased to 1.0 g 3 times a day.

Before prescribing a drug to a patient, it is advisable to determine the sensitivity to it of the microflora that caused the disease in this patient.

It should be remembered that the effectiveness of treatment for sinusitis will greatly depend on how well you apply the drops and remove all the side symptoms of the disease. It is recommended to remove them with vasoconstrictor sprays or special drops that contain antibiotics.

Remember that before you start treating sinusitis with antibiotics, you need to check if you have a fever. All cold symptoms should also be completely cured.

How to take Amoxicillin when treating sinusitis?

If you are still planning to treat sinusitis with Amoxicillin, then remember that the bulk of the antibiotic will be injected into the sinuses. With thorough treatment, many doctors prescribe several types of antibiotics in addition to Amoxicillin. Moreover, they can affect both the entire body and a specific part of it.

Use during pregnancy

An antibiotic for the treatment of sinusitis can also be used during pregnancy, but only on condition that the result of such treatment does not exceed the level of risk for the unborn child. In this case, amoxicillin should be taken under the constant supervision of the attending physician.

Women during lactation are advised to interrupt breastfeeding while taking the antibiotic in order to prevent the development of allergic reactions in the baby (their appearance is due to the penetration of the active components of the drug into the milk). In this case, we recommend not only reading amoxiclav reviews and instructions, but also consulting a doctor.
