How Zithromax Is Used as an Antibiotic

I hate being sick. I almost feel over once while out and had to grab something to keep upright.

Azithromycin is not approved for preventing bronchiolitis obliterans syndrome. It is an FDA-approved antibiotic used to treat many types of infections affecting the lungs, sinuses, skin, and other parts of the body. The drug has been used for more than 26 years.

It is sold under the brand names Zithromax and Zmax and as generics by many different drug companies. It works by stopping the growth of bacteria that can cause infections. There are no known effective antibiotic treatments for prophylaxis of bronchiolitis obliterans syndrome. Health care professionals should not prescribe long-term azithromycin for prophylaxis of bronchiolitis obliterans syndrome to patients who undergo donor stem cell transplants because of the increased potential for cancer relapse and death.

Children weighing 34 kilograms kg or more—Dose is based on body weight and must be determined by your doctor. The dose is usually 2 grams once a day, taken as a single dose. Children 6 months of age and older weighing less than 34 kg—Dose is based on body weight and must be determined by your doctor.

Depending on the type of infection, this may be followed with doses of to mg once a day for several days. Children 6 months of age and older—Dose is based on body weight and must be determined by your doctor. The dose is usually 10 to 30 milligrams mg per kilogram kg of body weight once a day, taken as a single dose.

Depending on the type of infection, this may be followed with doses of 5 to 10 mg per kg of body weight once a day for several days. Children younger than 6 months of age—Use and dose must be determined by your doctor. For treatment of pharyngitis or tonsillitis: Adults— milligrams mg on Day 1 the first day , taken as a single dose.

Then, mg on Day 2 through Day 5. Children 2 years of age and older—Dose is based on body weight and must be determined by your doctor.

The dose is usually 12 milligrams mg per kilogram kg of body weight once a day for 5 days. Children younger than 2 years of age—Use and dose must be determined by your doctor. Missed Dose If you miss a dose of this medicine, take it as soon as possible.

However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses. Storage Keep out of the reach of children. Do not keep outdated medicine or medicine no longer needed. Ask your healthcare professional how you should dispose of any medicine you do not use. Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.

After water has been added to the powder, use the dose within 12 hours and throw away any unused liquid after your dose. A large cohort study found a small increase in the risk of cardiovascular death among people taking azithromycin. The risk was higher among those with other risk factors for heart disease , such as smoking, low physical activity levels, and a high body mass index BMI.

The study reported that when compared with amoxicillin, there were 47 additional cardiovascular deaths per 1 million azithromycin prescriptions. Among people with the highest risk of heart disease, there were more deaths per 1 million courses of azithromycin. This suggests that other antibiotics, such as amoxicillin, may be a safer option for people with heart disease or certain types of heart arrythmias.

In , the FDA issued a warning about the long term use of azithromycin in people with certain blood or lymph node cancers who have stem cell transplants.

Azithromycin for bronchitis in adults and children: instruction

Then, mg on Day 2 through Day 5. Fluconazole, in turn, can moderately affect the kinetic ability of Azithromycin.

Do not keep the oral liquid for more than 10 days. A well-thought-out decision on the advisability of treating a child with such a drug should be taken by a doctor.

Do not keep the oral liquid for more than 10 days. The antibiotic is characterized by an extended spectrum of antimicrobial activity, as it affects the staphylococci, streptococci, hemophilic infection, moraecella, bordetella, info, legionella, neisheria, gardnerella, bacteroids, peptostreptococci, peptococci, clostridia, chlamydia, mycobacteria, mycoplasma, ureaplasma, spirochetes.

Of the enrolled patients, had a Type 1 acute exacerbation of chronic bronchitis AECBthree patients had pneumonia, and 18 had purulent bronchitis.

Mycoplasma pneumonia and Chlamydia pneumonia are bacterial etiologies that can affect young adults. However, trials showing that treatment shortens the course of these infections, even when initiated early, are lacking. Bordetella pertussis, the causative agent in pertussis, can also lead to acute bronchitis. Treatment Treatment of acute bronchitis is typically divided into two categories: antibiotic therapy and symptom management. Physicians appear to deviate from evidence-based medical practice in the treatment of bronchitis more than in the diagnosis of the condition.

Although 90 percent of bronchitis infections are caused by viruses, approximately two thirds of patients in the United States diagnosed with the disease are treated with antibiotics. A survey showed that 55 percent of patients believed that antibiotics were effective for the treatment of viral upper respiratory tract infections, and that nearly 25 percent of patients had self-treated an upper respiratory tract illness in the previous year with antibiotics left over from earlier infections.

The meta-analysis also showed a number needed to harm based on antibiotic adverse effects of Outcomes at days 3 and 7 were no different between the two groups, and 89 percent of patients in both groups had clinical improvement. When pertussis is suspected as the etiology of cough, initiation of a macrolide antibiotic is recommended as soon as possible to reduce transmission; however, antibiotics do not reduce duration of symptoms.

Antiviral medications for influenza infection may be considered during influenza season for highrisk patients who present within 36 hours of symptom onset. An argument for the use of antibiotics in acute bronchitis is that it may decrease the risk of subsequent pneumonia. Azithromycin for acute bronchitis: a randomised, double-blind, controlled trial Lancet.

We have investigated this question in a randomised, double-blind, controlled trial. All individuals were also given liquid dextromethorphan and albuterol inhaler with a spacer. The primary outcome was improvement in health-related quality of life at 7 days; an important difference was defined as 0.

Analysis was by intention to treat.

Greene's Wellness RecommendationsSignup now to get Dr. How to tell if the drug is working: Your infection should go zithromax. Summary The recommendations in this report were developed to broaden the spectrum of antimicrobial agents that are available why treatment and postexposure prophylaxis of pertussis. However, neither vaccination nor natural disease confers complete or lifelong protective immunity against pertussis or reinfection.

Neither erythromycin nor clarithromycin should be administered concomitantly with astemizole, cisapride, pimazole, or terfenadine. Poor penetration into respiratory secretions was proposed as a possible mechanism for failure to clear B.

This could result in dangerous side effects. Childhood vaccination coverage for pertussis vaccines has been at an all-time high 4. Do not keep the oral liquid here more than 10 days. This may cause liver damage or an irregular heart rhythm.

Although children are often exhausted after a coughing paroxysm, they usually appear relatively well between episodes.

But if more here remember just a few hours before your next scheduled dose, take only one dose. For prevention, typical dosage is 1, mg once per week. References CDC. For skin and skin structure infections Adult dosage ages 18 years and older Your doctor may prescribe mg taken in a single dose on day 1, why by mg once per day on days 2 through 5.

Mawle, PhD, Acting Director. Telephone: ; Fax: ; Email: tit2 cdc. Summary The recommendations in this report were developed to broaden the spectrum of antimicrobial agents that are available for treatment and postexposure prophylaxis of pertussis.

They include updated information on macrolide agents other than erythromycin azithromycin and clarithromycin and their dosing schedule by age group.

Introduction Pertussis is an acute bacterial infection of the respiratory tract that is caused by Bordetella pertussis, a gram-negative bacterium Box 1. The national pertussis surveillance system is passive and relies on physicians to report cases of pertussis to state and local health departments, which then report cases of pertussis weekly to the National Notifiable Diseases Surveillance System NNDSS.

Despite high childhood vaccination coverage levels for pertussis vaccine 3 , 4 , pertussis remains a cause of substantial morbidity in the United States. Pertussis is the only disease for which universal childhood vaccination is recommended that has an increasing trend in reported cases in the United States. The disease is endemic in the United States with epidemic cycles every years. In the early vaccine years during , an average annual rate of per , population was reported 5,6.

After introduction of universal vaccination during the s, the incidence of reported pertussis declined dramatically to approximately one case per , population. During the preceding 3 decades, reports of pertussis steadily increased again in the United States, from a nadir of 1, cases in 3 to 25, in rate: 8.

Increased awareness and improved recognition of pertussis among clinicians, greater access to and use of laboratory diagnostics especially extensive polymerase chain reaction [PCR] testing , and increased surveillance and reporting of pertussis by public health departments could have contributed to the increase in reported cases 8.

Some of the reported increase might constitute a real increase in the incidence of pertussis 9. Although infants have the highest incidence of pertussis of any age group, adolescents and adults account for the majority of reported cases.

Clinical Manifestations The incubation period of pertussis averages days range: days 6,10 and has been reported to be as long as 6 weeks 11, Pertussis has an insidious onset with catarrhal symptoms nasal congestion, runny nose, mild sore-throat, mild dry cough, and minimal or no fever that are indistinguishable from those of minor respiratory tract infections. Some infants can have atypical disease and initially have apneic spells and minimal cough or other respiratory symptoms.

The catarrhal stage last approximately weeks. The cough, which is initially intermittent, becomes paroxysmal. A typical paroxysm is characterized by a succession of coughs that follow each other without inspiration. Paroxysms terminate in typical cases with inspiratory "whoop" and can be followed by posttussive vomiting. Although children are often exhausted after a coughing paroxysm, they usually appear relatively well between episodes. Paroxysms of cough usually increase in frequency and severity as the illness progresses and usually persist for weeks.

Paroxysms can occur more frequently at night. The illness can be milder and the characteristic whoop absent in children, adolescents, and adults who were previously vaccinated. Convalescence is gradual and protracted.

The severity of illness wanes, paroxysms subside, and the frequency of coughing bouts decreases. A nonparoxysmal cough can continue for weeks or longer. During the recovery period, superimposed viral respiratory infections can trigger a recurrence of paroxysms. Patients with pertussis often have substantial weight loss and sleep disturbance Conditions resulting from the effects of the pressure generated by severe coughing include pneumothorax, epistaxis, subconjunctival hemorrhage, subdural hematoma, hernia, rectal prolapse, urinary incontinence, and rib fracture Some infections are complicated by primary or secondary bacterial pneumonia and otitis media.

Infrequent neurologic complications include seizures and hypoxic encephalopathy. Adolescents and adults with unrecognized or untreated pertussis contribute to the reservoir of B. Patients with pertussis are most infectious during the catarrhal stage and during the first 3 weeks after cough onset.

Differential Diagnosis The differential diagnoses of pertussis include infections caused by other etiologic agents, including adenoviruses, respiratory syncytial virus, Mycoplasma pneumoniae, Chlamydia pneumoniae, and other Bordetella species such as B.

Despite increasing awareness and recognition of pertussis as a disease that affects adolescents and adults, pertussis is overlooked in the differential diagnosis of cough illness in this population Prevention Vaccination of susceptible persons is the most important preventive strategy against pertussis.

Universal childhood pertussis vaccine recommendations have been implemented since the mids. For protection against pertussis during childhood, the Advisory Committee on Immunization Practices ACIP recommends 5 doses of diphtheria and tetanus toxoid and acellular pertussis DTaP vaccine at ages 2, 4, 6, months, and years Childhood vaccination coverage for pertussis vaccines has been at an all-time high 4. However, neither vaccination nor natural disease confers complete or lifelong protective immunity against pertussis or reinfection.

Immunity wanes after years from the last pertussis vaccine dose 3 ,8, Older children, adolescents, and adults can become susceptible to pertussis after a complete course of vaccination during childhood. ACIP voted to recommend a single dose of Tdap for adolescents aged years in June and adults aged years in October Treatment of Pertussis Maintaining high vaccination coverage rates among preschool children, adolescents, and adults and minimizing exposures of infants and persons at high risk for pertussis is the most effective way to prevent pertussis.

Antibiotic treatment of pertussis and judicious use of antimicrobial agents for postexposure prophylaxis will eradicate B. A macrolide administered early in the course of illness can reduce the duration and severity of symptoms and lessen the period of communicability Close asymptomatic contacts 38 Box 3 can be administered postexposure chemoprophylaxis to prevent secondary cases; symptomatic contacts should be treated as cases.

Erythromycin, a macrolide antibiotic, has been the antimicrobial of choice for treatment or postexposure prophylaxis of pertussis. It is usually administered in 4 divided daily doses for 14 days.

Although effective for treatment Table 1 and postexposure prophylaxis Table 2 , erythromycin is accompanied by uncomfortable to distressing side effects that result in poor adherence to the treatment regimen.

During the last decade, in vitro studies have demonstrated the effectiveness against B. Results from in vitro studies are not always replicated in clinical studies and practice. A literature search and review was conducted for in vivo studies and clinical trials that were conducted during and used clarithromycin or azithromycin for the treatment and prophylaxis of pertussis Table 3.

On the basis of this review, guidelines were developed to broaden the spectrum of macrolide agents available for pertussis treatment and postexposure prophylaxis and are presented in this report to update previous CDC recommendations Treatment and postexposure prophylaxis recommendations are made on the basis of existing scientific evidence and theoretical rationale.

Recommendations I. General Principles A. The choice of antimicrobial for treatment or prophylaxis should take into account effectiveness, safety including the potential for adverse events and drug interactions , tolerability, ease of adherence to the regimen prescribed, and cost. Erythromycin and clarithromycin, but not azithromycin, are inhibitors of the cytochrome P enzyme system CYP3A subclass and can interact with other drugs that are metabolized by this system.

Azithromycin and clarithromycin are more resistant to gastric acid, achieve higher tissue concentrations, and have a longer half-life than erythromycin, allowing less frequent administration doses per day and shorter treatment regimens days.

Erythromycin is available as generic preparations and is considerably less expensive than azithromycin and clarithromycin. Postexposure prophylaxis. A macrolide can be administered as prophylaxis for close contacts of a person with pertussis if the person has no contraindication to its use.

The decision to administer postexposure chemoprophylaxis is made after considering the infectiousness of the patient and the intensity of the exposure, the potential consequences of severe pertussis in the contact, and possibilities for secondary exposure of persons at high risk from the contact e.

For postexposure prophylaxis, the benefits of administering an antimicrobial agent to reduce the risk for pertussis and its complications should be weighed against the potential adverse effects of the drug. Administration of postexposure prophylaxis to asymptomatic household contacts within 21 days of onset of cough in the index patient can prevent symptomatic infection.

Coughing symptomatic household members of a pertussis patient should be treated as if they have pertussis. The recommended antimicrobial agents and dosing regimens for postexposure prophylaxis are the same as those for treatment of pertussis Table 4.

The U. Data from subsets of infants aged months enrolled in small clinical studies suggest similar microbiologic effectiveness of azithromycin and clarithromycin against pertussis as with older infants and children.

If not treated, infants with pertussis remain culture-positive for longer periods than older children and adults 36, These limited data support the use of azithromycin and clarithromycin as first-line agents among infants aged months, based on their in vitro effectiveness against B. In this age group, the risk for acquiring severe pertussis and its life-threatening complications outweigh the potential risk for IHPS that has been associated with erythromycin A comprehensive description of the safety of the recommended antimicrobials is available in the package insert, or in the latest edition of the Red Book: Pharmacy's Fundamental Reference.

A macrolide is contraindicated if there is history of hypersensitivity to any macrolide agent Table 5. Neither erythromycin nor clarithromycin should be administered concomitantly with astemizole, cisapride, pimazole, or terfenadine.

The most commonly reported side effects of oral macrolides are gastrointestinal e. Specific Antimicrobial Agents 1. Azithromycin is available in the United States for oral administration as azithromycin dihydrate suspension, tablets, and capsules.

It is administered as a single daily dose. Adults: mg on day 1, followed by mg per day on days Side effects include abdominal discomfort or pain, diarrhea, nausea, vomiting, headache, and dizziness. Azithromycin should be prescribed with caution to patients with impaired hepatic function. All patients should be cautioned not to take azithromycin and aluminum- or magnesium-containing antacids simultaneously because the latter reduces the rate of absorption of azithromycin.

This is one of several reasons that azithromycin along with erythromycin, an older antibiotic in the same class is not recommended for use in children under 6 months of age when another antibiotic is available see article on Pyloric Stenosis as well.

Azithromycin is processed by the liver. The immature livers of infants in the first months of life are less ready to handle this, making the risk of jaundice greater.

A baby is not simply a little adult , but a developing child with unique metabolic capabilities. If given Zithromax in a powder form, mix it with water right before giving your child the dose. Dosage Depending on the condition being treated, your healthcare provider will usually tailor the dose based on your child's height and weight measured in kilograms, kg.

In such a case, skip the dose and give your child the next one as you normally would. Never double up on doses as this can increase the risk of side effects.
