Generic Erythromycin is created by pharmacy specialists to struggle against infections (pneumonia, Legionnaire's disease, sexually transmitted diseases, skin infections). It is also helpful in treatment of severe acne and prevention of heart diseases in people who suffer from rheumatic fever. Target of Generic Erythromycin is to control, ward off and terminate bacteria.

Generic Erythromycin acts as an anti-infection remedy. Generic Erythromycin operates by killing bacteria which spreads by infection. Generic Erythromycin and other antibiotics don't treat viral infections (flu, cold and other). Generic Erythromycin is a macrolide antibiotic.

Generic name of Generic Erythromycin is Erythromycin. Brand names of Generic Erythromycin are Erythromycin, MY-E, Erythrocin Stearate Filmtab, E-Mycin, Ery-Tab, E.E.S.-200, Robimycin, E.E.S.-400, Eryc, EryPed, Erythrocot, CE Dispertab.


Patients should be counseled that antibacterial drugs including Erythromycin Tablets should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When Erythromycin Tablets are prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by Erythromycin Tablets or other antibacterial drugs in the future.

Diarrhea is a common problem caused by antibiotics which usually ends when the antibiotic is discontinued. Sometimes after starting treatment with antibiotics, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as two or more months after having taken the last dose of the antibiotic. If this occurs, patients should contact their physician as soon as possible.


You overdose Generic Erythromycin and you don't feel good you should visit your doctor or health care provider immediately. Symptoms of Generic Erythromycin overdosage: retching, diarrhea, pain of stomach, loss of hear, nausea.


Store at room temperature between 15 and 30 degrees C (59 and 86 degrees F) away from heat, moisture, and direct light. Keep from freezing. Keep container tightly closed. Throw away any unused medicine after the expiration date. Keep out of the reach of children.

Prescribing Erythromycin Tablets in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.

Since Erythromycin is principally excreted by the liver, caution should be exercised when Erythromycin is administered to patients with impaired hepatic function.

Exacerbation of symptoms of myasthenia gravis and new onset of symptoms of myasthenic syndrome has been reported in patients receiving Erythromycin therapy.

There have been reports of infantile hypertrophic pyloric stenosis (IHPS) occurring in infants following Erythromycin therapy. In one cohort of 157 newborns who were given Erythromycin for pertussis prophylaxis, seven neonates (5%) developed symptoms of non-bilious vomiting or irritability with feeding and were subsequently diagnosed as having IHPS requiring surgical pyloromyotomy. A possible dose-response effect was described with an absolute risk of IHPS of 5.1% for infants who took Erythromycin for 8 to 14 days and 10% for infants who took Erythromycin for 15 to 21 days.5 Since Erythromycin may be used in the treatment of conditions in infants which are associated with significant mortality or morbidity (such as pertussis or neonatal Chlamydia trachomatis infections), the benefit of Erythromycin therapy needs to be weighed against the potential risk of developing IHPS. Parents should be informed to contact their physician if vomiting or irritability with feeding occurs.

Prolonged or repeated use of Erythromycin may result in an overgrowth of nonsusceptible bacteria or fungi. If superinfection occurs, Erythromycin should be discontinued and appropriate therapy instituted.

When indicated, incision and drainage or other surgical procedures should be performed in conjunction with antibiotic therapy.

Observational studies in humans have reported cardiovascular malformations after exposure to drug products containing Erythromycin during early pregnancy.

Primary cultures of rat hepatocytes were exposed to several concentrations of erythromycin estolate (EE). Hepatotoxicity was evaluated using lactate dehydrogenase (LDH) leakage and morphometric analysis of representative populations of cells examined optically. Results of the two techniques provided parallel information: cells exposed to the higher concentrations of EE had significantly greater LDH release and higher percentages of morphologically damaged cells. Planimetric analysis of a second set of hepatocytes showed increasing swelling of cells with increasing concentration of EE. Severe cellular swelling preceded disintegration, as hepatocytes became progressively more damaged by EE.

More than 120,000 patients are treated annually in Germany to resolve repeated episodes of acute tonsillitis. Therapy is aiming at symptom regression, avoidance of complications, reduction in the number of disease-related absences in school or at work, increased cost-effectiveness and improved quality of life. The purpose of this part of the guideline is to provide clinicians in any setting with a clinically focused multi-disciplinary guidance through different conservative treatment options in order to reduce inappropriate variation in clinical care, improve clinical outcome and reduce harm. Surgical management in terms of intracapsular as well as extracapsular tonsillectomy (i.e. tonsillotomy) is the subject of part II of this guideline. To estimate the probability of tonsillitis caused by β-hemolytic streptococci, a diagnostic scoring system according to Centor or McIsaac is suggested. If therapy is considered, a positive score of ≥3 should lead to pharyngeal swab or rapid test or culture in order to identify β-hemolytic streptococci. Routinely performed blood tests for acute tonsillitis are not indicated. After acute streptococcal tonsillitis, there is no need to repeat a pharyngeal swab or any other routine blood tests, urine examinations or cardiological diagnostics such as ECG. The determination of the antistreptolysin O-titer (ASLO titer) and other antistreptococcal antibody titers do not have any value in relation to acute tonsillitis with or without pharyngitis and should not be performed. First-line therapy of β-hemolytic streptococci consists of oral penicillin. Instead of phenoxymethylpenicillin-potassium (penicillin V potassium), also phenoxymethlpenicillin-benzathine with a clearly longer half-life can be used. Oral intake for 7 days of one of both the drugs is recommended. Alternative treatment with oral cephalosporins (e.g. cefadroxil, cefalexin) is indicated only in cases of penicillin failure, frequent recurrences, and whenever a more reliable eradication of β-hemolytic streptococci is desirable. In cases of allergy or incompatibility of penicillin, cephalosporins or macrolides (e.g. Erythromycin-estolate) are valuable alternatives.

Although 14 days of erythromycin is recommended for the treatment of Bordetella pertussis infection, there have been no prospective controlled studies to support the contention that this long course of therapy is required to eradicate the microorganism from the nasopharynx or to prevent bacteriological relapse. We randomly allocated children and adults with culture-positive community-acquired pertussis to either 7 or 14 days of erythromycin estolate treatment (40 mg/kg/d; maximum dose 1 g/d). Nasopharyngeal aspirate cultures were obtained by study nurses during home visits before and at the end of treatment, and 1 week after the completion of treatment. B pertussis-specific antibodies were measured before treatment and 1 month later. Information about clinical symptoms, adverse reactions, and compliance were collected at each scheduled contact.

Seventeen (36.2%) of the 47 patients had a positive culture the morning after initiating antibiotic therapy. However, thirty-nine (83%) of the patients became "culture negative" within the first 24 hours. Neither the time interval to the first negative culture nor the presence or absence of group A streptococcal organisms on any single convalescent culture could be predicted by clinical findings. Six of the eight children who failed to convert to a "negative" throat culture within 24 hours of initiating therapy were receiving erythromycin. We could detect no difference in either time to conversion to a negative culture or the presence of a positive culture 24 hours after starting antibiotics between those who demonstrated a significant antibody increase and those who did not.

erythromycin and alcohol

The effect of acute and chronic endotoxin (LPS) treatment on the erythromycin estolate (EE) induced cholestasis, was studied using the isolated perfused rat liver. Addition of EE markedly reduced bile and perfusate flows in livers from control rats but did not alter these parameters in livers from endotoxin pretreated rats or in vitro treated with LPS. We suggest that changes in membrane organization induced by LPS may alter the diplay of EE toxicity.

Primary cultures of rat hepatocytes were used to study the effects of the flavonoids diosmin and its main metabolite diosmetin on the cell membrane damage caused by erythromycin estolate (EE) and oxidative stress caused by tert-butylhydroperoxide (TBHP). The damage was evaluated by the leakage of intracellular enzymes lactate dehydrogenase, aspartate-aminotransferase and the residual cell content of a lysosomal marker acid phosphatase (AP). After treating the cells for 40 h with diosmetin EE induced less enzyme leakage. The content of AP was kept higher by diosmetin pretreatment after 6 h exposure to EE. Diosmin at the same concentrations had barely any effect. Diosmetin, but not diosmin, also protected against TBHP toxicity and this was related to lower lipid peroxidation and higher glutathione content caused by pretreatment with the flavonoid. When the cells were treated simultaneously with TBHP and diosmetin after 21 h of culture, the protection by the flavonoid was even higher. In fact the antioxidant activity of diosmetin was considerably greater than that of diosmin. After 40 h exposure to both flavonoids diosmin but not diosmetin was detectable in the cell membrane fraction, suggesting that the latter's protective effect is associated with its metabolites.

Erythromycin estolate (EE), a macrolide antibiotic, has caused hepatotoxicity both in human and experimental animals. The objective of this study was to integrate general toxicology, transcriptomics, and metabonomics approaches to determine the mechanisms of EE-induced liver injury. Histopathological examinations unveiled dose-dependent hydropicdegenerationof hepatocytes after EE administration. Further biochemical analysis of treated rats confirmed that cholestasis and oxidative stress were induced by EE treatments. Microarray analysis of the livers from EE-treated rats showed that differentially expressed genes were enriched in the ABC transporters, cell cycle, and p53 signaling pathways. Metabonomics analysis revealed that EE exposure could lead to disturbances in energy metabolism, amino acid metabolism, lipid metabolism, and nucleotide metabolism, which may be attributable to EE toxicological effects on the liver through oxidative stress. 5-Oxoproline may be used as a biomarker of EE-induced liver injury. More importantly, the integrated analysis of transcriptomics and metabonomics datasets demonstrated that the induction of ABC transporters pathway severed as an anti-cholestatic adaptive mechanism in EE-induced cholestasis. In addition, EE-induced liver injury was also related to alteration in glycogen and sucrose metabolism, arachidonic acid metabolism, and linoleic acid metabolism pathways.

Although a possible microbial etiology was identified in 43% of the evaluable patients, clinical findings and results of blood cultures, chest radiographs and white blood cell and differential counts did not distinguish patients with a defined etiology from those without a known cause for pneumonia. There were no differences in the clinical responses of patients to the antimicrobial regimens studied.

Topical antibiotics were used on patients with acne vulgaris. Corynebacterium acnes organisms from open comedones were quantitated during treatment, and the progress of the disease was evaluated. Clindamycin lotion completely suppressed the growth of C acnes organisms, whereas erythromycin and tetracycline did not depress the C acnes counts. Taken as a group, these antibiotics gave a substantial improvement of the disease on the treated side as compared with paired untreated sides of the face and back.

will erythromycin treat urinary tract infection 2016-03-11

Children who were 6 months to 16 years of age and had cough illness that was suspected to be or was culture confirmed as pertussis were randomized to azithromycin (10 mg/kg on day 1 and 5 mg/kg on days 2-5 as a single dose) or erythromycin estolate (40 mg/kg/day in 3 divided doses for 10 days) with stratification by center. The primary outcome measure was bacteriologic cure of infection as determined by cultures of nasopharyngeal aspirates. Culture-positive participants had a second aspirate collected at the end of therapy (days 5-7 for azithromycin, days 10-12 for erythromycin) and 1 week after therapy. Bacteriologic cure was defined as negative cultures at the end of therapy. Bacteriologic relapse was defined as a positive culture 1 week after completion of therapy and after a negative end-of-therapy culture. Secondary outcomes were pertussis diagnosed by serology and polymerase chain reaction (PCR), treatment-associated adverse events, compliance, and presence of clinical symptoms at the end of the treatment course. Serology was performed using standard enzyme-linked immunosorbent assay methods. A participant was considered to have pertussis when the PCR was positive or a 4-fold increase in pertussis toxin antibody between baseline and follow-up visits was observed. PCR was performed using a 1046-bp ClaI DNA fragment from B pertussis. Adverse events (nausea, vomiting, diarrhea, any gastrointestinal complaint, or other) were determined by a parent-completed diary that was reviewed with study personnel during study visits. Compliance was measured by review of the parent medication diary during study visits and observation of medication containers by the pharmacist at study completion. Symptoms were determined by history collected by study personnel at enrollment and subsequently from the diary. The design of the study was an equivalence trial, aimed at demonstrating that the bacteriologic failure rates with the 2 therapies did not differ by >8%. Azithromycin 5 Day Dose Pack 250 For the safety analysis, all participants who received at least 1 dose of study drug were included. In the per-protocol efficacy analysis, all culture-positive participants with end-of-treatment cultures were considered.

We conducted a nested case-control study to estimate and compare the relative risks for hospitalizations for newly diagnosed acute liver injury associated with the use of non-steroidal antiinflammatory drugs (NSAIDs) and other hepatotoxic drugs and their interaction. The source population comprised 228,392 members of the Saskatchewan Health Plan from 1982 to 1986. We used hospital records and the databases of the Department of Health. Thirty-four cases with confirmed liver injury were hospitalized. We randomly selected 500 controls from the source population. Crude risks ranged from 1 case per 100,000 prescriptions in current users of methyldopa, ampicillin, or NSAIDs to 14 cases per 100,000 prescriptions in current users of erythromycin estolate. The age-adjusted odds ratios for current users of NSAIDs was 1.8 [95% confidence interval (CI) = 0.8-3.7] and for other hepatotoxic drugs 5.9 (95% CI = 2.8-12.4). The adjusted relative excess risk due to the interaction between current exposure to both categories of drugs was 3.6 Nolicin 500 Mg , accounting for 31% of the cases of acute liver injury among those with exposure to both types of drugs. We conclude that the risk of hospitalization for acute noninfectious liver injury is different among users of various individual potentially hepatotoxic drugs. Concomitant current exposure to two or more drugs increases this risk above what would merely be expected from the sum of the individual risks.

A 53-year-old housewife who had developed severe cholestatic hepatitis following the administration of erythromycin estolate therapy two-and-a-half years previously, was studied by an in vitro "challenge" test in which peripheral venous lymphocytes were cultured in the presence of erythromycin estolate, erythromycin stearate Is Levaquin A Strong Antibiotic and erythromycin base. Evidence of blastogenesis was observed in response to erythromycin estolate, but not to erythromycin stearate of erythromycin base. This test thus provided evidence that the patient was "sensitized" to erythromycin estolate without exposing her to the risk of in vivo challenge. Furthermore, in contrast to previous studies, the findings provide evidence that erythromycin estolate jaundice is mediated by immunological mechanisms.

Treatment of rats with pregnenolone-16 alpha-carbonitrile (PCN) markedly induces rat liver Vanadyl 400 Mg microsomal cytochrome P-450p and UDP-GT-dt1, a glucuronosyltransferase active towards the digitoxin metabolite, digitoxigenin monodigitoxoside. The present study characterizes the regulation of these two enzymes in rats treated with different xenobiotics. Like PCN, treatment of rats with dexamethasone, spironolactone, troleandomycin or erythromycin estolate markedly induced both UDP-GT-dt1 and cytochrome P-450p (measured as erythromycin demethylase and testosterone 2 beta-, 6 beta-, 15 beta-, and 18-hydroxylase activities). However, compared to PCN and dexamethasone, both troleandomycin and erythromycin estolate preferentially induced cytochrome P-450p, whereas spironolactone preferentially induced UDP-GT-dt1. Treatment of rats with the polychlorinated biphenyl mixture, Aroclor 1254, increased both cytochrome P-450p and UDP-GT-dt1 activity to about 40% of that in liver microsomes from rats induced with PCN or dexamethasone. Treatment of rats with phenobarbital or chlordane caused a relatively small increase in cytochrome P-450p and UDP-GT-dt1 activity. Neither enzyme was induced by treatment of rats with 3-methylcholanthrene, rifampin or digitoxin. The induction of cytochrome P-450p and UDP-GT-dt1 by PCN followed similar dose-response curves. Although cytochrome P-450p and UDP-GT-dt1 are differentially affected by the age and the sex of rats, the enzymes responded similarly, but not identically, to xenobiotic treatment. This suggests that cytochrome P-450p and UDP-GT-dt1 are co-inducible but not coordinately regulated.
