Erythromycin is a prescription medication used to treat infections caused by bacteria. Erythromycin belongs to a group of drugs called macrolide antibiotics. These work by killing or stopping the growth of the bacteria that cause infections. This medication comes in capsule, tablet, long-acting capsule, long-acting tablet, chewable tablet, suspension, and pediatric drop forms for oral use. It is usually taken 3 to 4 times daily.

This medication also comes in topical solution and gel forms and as an ophthalmic ointment. Do not chew, divide, or break the long-acting capsules and tablets. Swallow these whole and take with a full glass of water. This medication is also available in an injectable form to be given directly into a vein (IV) by a healthcare professional. Common side effects of Erythromycin include stomach upset, diarrhea, vomiting, stomach cramps, mild skin rash, and stomach pain. Ophthalmic Erythromycin can also cause blurred vision. Do not drive or operate heavy machinery until you know how Erythromycin affects you.


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.


If you take too much erythromycin, call your healthcare provider or local Poison Control Center, or seek emergency medical attention right away.

If erythromycin is administered by a healthcare provider in a medical setting, it is unlikely that an overdose will occur. However, if overdose is suspected, seek emergency medical attention.


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.

Side effect occurrence does not only depend on medication you are taking, but also on your overall health and other factors.


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.

One trial involving 1071 women was included. Of these, 644 randomly received antibiotic treatment (174 erythromycin estolate, 224 erythromycin sterate, and 246 clindamycin hydrochloride) and 427 received placebo. This trial did not report data on preterm birth. Incidence of low birthweight less than 2500 grams was only evaluated for erythromycin (combined) (n = 398 ) compared to placebo (n = 427) and there was no statistically significant difference between those treated and those not treated (relative risk (RR) 0.70, 95% confidence interval (CI) 0.46 to 1.07). In regards to side-effects sufficient to stop treatment, data were available for all women, and there were no statistically significant differences between any antibiotic (combined) and the placebo group (RR 1.25, 95% CI 0.85 to 1.85).

Chlamydia trachomatis is an obligate intracellular parasite responsible for many clinical syndromes, including neonatal conjunctivitis and pneumonia. The gold standard of diagnosis has been isolation in cell culture. However, this requires days of processing. Several rapid diagnostic tests are available. Giemsa staining of conjunctival smears, enzyme immunoassay, and the fluorescein-conjugated monoclonal antibody test. Both the EIA and the FA tests show promise as ideal rapid diagnostic tests. Treatment of chlamydial conjunctivitis must focus upon the eradication of nasopharyngeal carriage as well as cure of ophthalmic symptoms. The need for nasopharyngeal eradication is underscored by the fact that it is the source for chlamydial pneumonia as well as for conjunctival re-infection. Clinical studies have shown that oral erythromycin estolate or ethylsuccinate suspension 50 mg/kg/day twice-daily or four times a day for 14 to 21 days are the therapeutic regimens of choice. Neonatal ocular prophylaxis is currently under study. One per cent silver nitrate does not prevent chlamydial conjunctivitis but preliminary studies do show favorable results with topical erythromycin. Nevertheless, neither 1 per cent silver nitrate nor topical erythromycin eradicate nasopharyngeal carriage, elimination of which is necessary for the prevention of neonatal chlamydial pneumonia.

The purpose of this study was to describe and compare the pharmacokinetic properties of different formulations of erythromycin in dogs. Erythromycin was administered as lactobionate (10 mg/kg, IV), estolate tablets (25 mg/kg p.o.) and ethylsuccinate tablets or suspension (20 mg/kg p.o.). After intravenous (i.v.) administration, the principal pharmacokinetic parameters were (mean +/- SD): AUC((0-infinity)) 4.20 +/- 1.66 microg x h/mL; C(max) 6.64 +/- 1.38 microg/mL; V(z) 4.80 +/- 0.91 L/kg; Cl(t) 2.64 +/- 0.84 L/; t((1/2)lambda) 1.35 +/- 0.40 h and MRT 1.50 +/- 0.47 h. After the administration of estolate tablets and ethylsuccinate suspension, the principal pharmacokinetic parameters were (mean +/- SD): C(max), 0.30 +/- 0.17 and 0.17 +/- 0.09 microg/mL; t(max), 1.75 +/- 0.76 and 0.69 +/- 0.30 h; t((1/2)lambda), 2.92 +/- 0.79 and 1.53 +/- 1.28 h and MRT, 5.10 +/- 1.12 and 2.56 +/- 1.77 h, respectively. The administration of erythromycin ethylsuccinate tablets did not produce measurable serum concentrations. Only the i.v. administration rendered serum concentrations above MIC(90) = 0.5 microg/mL for 2 h. However, these results should be cautiously interpreted as tissue erythromycin concentrations have not been measured in this study and, it is recognized that they can reach much higher concentrations than in blood, correlating better with clinical efficacy.

In this work, the producing of a biodegradable poly(l-lactide) (PLA)/poly(ethylene glycol) (PEG) microcapsule by emulsion solvent evaporation method was investigated. The effect of PEG segments added to the PLA microcapsules on the degradation, size distribution, and release behavior was studied. According to the results, PLA/PEG copolymer was more hydrophilic than PLA homopolymer, and with lower glass transition temperature. The surface of PLA/PEG microcapsules was not as smooth as that of PLA microcapsules, the mean diameters of prepared PLA and PLA/PEG microcapsules were 40 and 57 microm, respectively. And spherical forms were observed by the image analyzer and the scanning electron microscope (SEM). Drug release from microcapsules was affected by the properties of PLA/PEG copolymers determined by UV-vis spectra. It was found that the drug release rates of the microcapsules were significantly increased with adding of PEG, which explained by increasing hydrophilic groups.

The use of antibiotics in pregnancy requires that the clinician consider both toxicity to and pharmacokinetics for mother and fetus. Although most adverse reactions to antibiotics in the adult are not modified by pregnancy, those to tetracycline and erythromycin estolate are the exceptions. Tetracycline is contraindicated throughout pregnancy because of fetal effects, whereas sulfa preparations, trimethoprim, and chloramphenicol are contraindicated only at specific times during gestation. The pharmacokinetics of antibiotics in the mother are such that lower serum concentrations are achieved for a given dose, which may be important in serious or resistant infections. Fetal kinetics are such that transfer to amniotic fluid and distribution within the fetus may not provide adequate protection for the fetus in cases of chorioamnionitis.

Although universal immunization against Bordetella pertussis (whooping cough) infection has resulted in dramatic reductions in the incidence of pertussis, outbreaks continue to occur in countries with excellent vaccine coverage. Treatment of infection may ameliorate symptom severity during the catarrhal phase of pertussis but has no effect on established paroxysms, emesis, or apnea if given during the paroxysmal or convalescent phases. Erythromycin, recommended for treatment of pertussis to prevent transmission of infection, is poorly tolerated because of gastrointestinal side effects. We compared the safety and efficacy of erythromycin with azithromycin for treatment of pertussis in a large, randomized, controlled trial that enrolled children from primary care practices in 1 American and 11 Canadian urban centers.

The failure rate in this study is unacceptably high for erythromycin to be used as a sterilization method.

erythromycin drug side effects

To investigate the mechanisms of erythromycin cholestasis, the effects of erythromycin estolate (EE) on the excretory function of the isolated perfused rat liver and on liver plasma membrane (LM) preparations were studied and compared to those of erythromycin base (EB) and lauryl sulfate (LS), added alone or in combination. EE (at 125 to 200 microM) caused dose-dependent reductions of bile and perfusate flows, bile acid (BA) excretion, and biliary BA concentration. The alterations of the excretory function were only in part due to the decreased perfusate flow. In contrast, both 200 and 300 microM concentrations of EB elicited similar choleretic responses, which were presumably related to the osmotic activity of the drug excreted in the bile. LS did not affect hepatic excretory functions. However, the simultaneous addition of EB and LS resulted in a rate of bile flow lower than that observed with EB alone. EE, but not EB, increased canalicular permeability to [14C]sucrose as measured by bile to plasma (B:P) ratio. Neither drugs altered [14C]erythritol B:P ratio. In LM preparations both Na+,K+- and Mg2+-ATPase activities were inhibited in a dose-dependent manner by EE, but not by EB. The data suggest that EE could affect bile flow by inhibiting cotransport of Na+ and BA and by altering LM permeability and support the view that the effect of erythromycins on the liver may be related to their surface activity.

A combined cholestatic and hepatocellular injury occurred in nine patients, following therapy with erythromycin estolate (EE) or other erythromycin derivatives. Eight of the nine patients developed jaundice within three weeks after initiation of treatment; pain was one of the main symptoms in five patients while fever and itching were noted in four patients. Symptoms and signs subsided and abnormal tests of liver function returned to normal after withdrawal of the drug. The major histologic finding was cholestasis, but the Clavam 325 Mg majority of cases also had evidence of hepatocellular injury of variable severity; one biopsy specimen showed centrilobular necrosis. Ultrastructural findings in one case included changes related to cholestasis as well as hepatocellular injury with striking mitochondrial abnormalities. Our data are compared with those of the literature, with special reference to morphologic features.

Only penicillin has been adequately studied in treating syphilis during pregnancy. It is safe for the fetus and highly effective in doses currently recommended by the USPHS. Since these schedules appear to represent a minimal effective dose, smaller amounts should never be used. Whether higher doses would produce higher cure rates is Cefixima 1000 Mg not known. Penicillin is the drug of choice and the standard against which all others must be measured. Tetracyclines in any dose or form should not be used because of toxicity to both mother and child. Erythromycin (except the estolate) and cephalosporins are promising because of low toxicity, but their efficacy has not been established.

A method is described for the determination of erythromycin estolate by liquid chromatography. A C18 reversed-phase column (25 x 0.46 cm i.d.) was used with acetonitrile-tetrabutylammonium sulphate (pH 6.5, 0.2 M)-phosphate buffer (pH 6.5, 0.2 M)-water [x:5:5:(90-x), v/v/v/v] as mobile phase. The proportion of acetonitrile (x) has to be adapted to the type of stationary phase used. For RSil C18 LL 42.5% (v/v) was used. The column was heated at 35 degrees C, the flow rate was 1.5 ml min-1 and UV detection was performed at 215 nm. The main component, erythromycin A propionate, was separated from all other components which were present Suprax Cost Comparison in commercial samples. The impurities most frequently observed were the propionate ester of erythromycin C and the amide N-propionyl-N-demethyl-erythromycin A. Erythromycin A was shown to be present in specialties.

The release rate of procaine penicillin, erythromycin and erythromycin estolate from soluble and insoluble collagen films was Sulfatrim Pill investigated in vitro to develop an ocular insert for the treatment of infectious bovine keratoconjunctivitis. The release rate and duration of release varied according to the selection of antibiotic and vehicle. The combination of erythromycin estolate and soluble collagen produced the most sustained drug-delivery system. However, due to the inappropriate physical properties of collagen and poor retention of ocular inserts, it was considered that the development of an antibiotic-impregnated collagen ocular insert requires further investigation.

At 12 months of use, the failure rate of the sterilization procedure for the crushed 500 mg tablets was 35.8% (SE = 1.8 Tricef 400 Mg Dose ) with 417 women at risk. At 12 months of use, the failure rate for the erythromycin pellets was 28.6% (SE = 5.0) with 43 women at risk. There were no serious complications reported in either trial. All pregnancies resulting from failure of the sterilization procedure were terminated by menstrual regulation within 10 weeks gestation.

Chang liver cells and isolated rat hepatocytes were exposed to medium containing different concentrations of erythromycin estolate or erythromycin base for 1-5 h. Hepatotoxicity was quantitated by Ceftin Drug Interactions measuring leakage of enzymes from cells into surrounding medium and the damage to the plasma cell membrane seen under surface scanning electron microscopy. Only the cells exposed to erythromycin estolate showed significantly greater enzyme leakage than controls and appeared severely affected by cytopathic changes when observed under scanning electron microscopy.

We examined the vaginal washings from patients with nonspecific vaginitis (NSV) to seek biochemical markers and possible explanations for the signs and symptoms of this syndrome. Seven amines were identified including methylamine, isobutylamine, putrescine, cadaverine, histamine, tyramine, and phenethylamine. These amines may contribute to the symptoms of NSV and may contribute to the elevated pH of the vaginal discharge. They may also be partly responsible for the "fishy" odor that is characteristic of vaginal discharges from these patients. Among the seven amines, putrescine and cadaverine were the most abundant and were present in all vaginal discharges from each of ten patients before treatment. These amines are produced in vitro during growth of mixed vaginal bacteria in chemically defined medium, presumably by decarboxylation of the corresponding amino acids. We hypothesize the anaerobic vaginal organisms, previously shown to be quantitatively increased in NSV, are responsible for the amine production, because metronidazole inhibited the production of amines by Loxof 500 Mg Dosage vaginal bacteria in vitro, and Haemophilus vaginalis did not produce amines. H. vaginalis did release high concentrations of pyruvic acid and of amino acids during growth in peptone-starch-dextrose medium, whereas, other vaginal flora consumed both pyruvic acid and amino acids in the same medium during growth. These findings suggest that a symbiotic relationship may exist between H. vaginalis and other vaginal flora in patients with NSV.

The effects of erythromycin Macladin Dose Bambini estolate, a well known hepatotoxic macrolide antibiotic, on isolated rat hepatocyte viability and on subcellular Ca2+ transport have been investigated. Erythromycin estolate (0.5 mM), but not erythromycin base and erythromycin ethylsuccinate, induced 100% cell death after 60 min incubation, and caused maximal inhibition of mitochondrial and microsomal Ca2+ sequestration activities at 0.1 mM concentration. Sodium lauryl sulphate, which is the surfactant moiety of the erythromycin estolate molecule, caused effects similar to those exhibited by erythromycin estolate. Disorders of the intracellular calcium homeostasis seem to play a role in the lauryl sulphate-mediated hepatotoxic action of erythromycin estolate.

In the field of gene expression analysis, DNA microarray technology is having a major impact on many different areas including toxicology. For instance, a number of studies have shown that transcription profiling can generate the information needed to assign a compound to a mode-of-action class. In this study, we investigated whether compounds inducing similar toxicological endpoints produce similar changes in gene expression. In vitro primary rat hepatocytes were exposed to 11 different hepatotoxicants: acetaminophen, amiodarone, clofibrate, erythromycin estolate, isoniazid, alpha-naphtylylisothiocyanate, beta-naphtoflavone, 4-pentenoic acid, phenobarbital, tetracycline, and zileuton. These molecules were selected on the basis of their variety of hepatocellular effects observed such as necrosis, cholestasis, steatosis, and induction of CYP P450 enzymes. We used a low-density DNA microarray containing 59 genes chosen as relevant toxic and metabolic markers. The in vitro gene expression data generated in this study were generally in good agreement with the literature, which mainly concerns in vivo data. Furthermore, gene expression profiles observed in this study have been confirmed for several genes by real-time PCR assays. All the tested drugs generated a specific gene expression profile. Our results show that even with a relatively limited gene set, gene expression profiling allows a certain degree of classification of compounds with similar hepatocellular toxicities such as cholestasis, necrosis. The clustering analysis revealed that the compounds known to cause steatosis were linked, suggesting that they functionally regulate similar genes and possibly act through the same mechanisms of action. On the other hand, the drugs inducing necrosis and cholestasis were pooled in the same cluster. The drugs arbitrarily classified as the CYP450 inducers formed individual clusters. In conclusion, this study suggests that low-density microarrays could be useful in toxicological studies.
