How It Works
Erythromycin binds to bacterial ribosomes, specifically the 50S subunit, inhibiting protein synthesis. This prevents bacteria from producing essential proteins needed for growth and reproduction. Unlike antibiotics that kill bacteria directly, Erythromycin is generally bacteriostatic, stopping bacterial growth while the immune system eliminates the infection.
Dosage
Patient Age | Standard Dosage | Maximum Daily Dosage |
---|---|---|
Adults | 500mg every 6-12 hours | 4,000mg (4g) daily |
Children | 30-50mg/kg/day divided | 2,000mg (2g) daily |
Take Erythromax tablets with a full glass of water, either 1 hour before or 2 hours after meals for optimal absorption. Complete the full prescribed course.
Duration of Action
Erythromax reaches therapeutic blood levels within 1-2 hours after oral administration. The drug remains active in the body for 6-12 hours, depending on the formulation. Treatment duration typically ranges from 7-14 days depending on the infection type and severity, though shorter or longer courses may be prescribed.
Side Effects
Common side effects include gastrointestinal disturbances such as nausea, vomiting, abdominal pain, and diarrhea. Some patients may experience allergic reactions, headache, or temporary hearing impairment with high doses. Rare but serious side effects include severe skin reactions, liver problems, and irregular heartbeat.
Warning
Complete the entire prescribed course even if symptoms improve. Skipping doses or stopping early can lead to antibiotic resistance and recurring infection. Erythromax may cause QT interval prolongation in susceptible individuals. Severe diarrhea occurring during or after treatment may indicate a serious intestinal condition (C. difficile-associated diarrhea).
Pregnancy and Breastfeeding
Erythromax is generally considered safe during pregnancy and is often the antibiotic of choice when treatment is necessary. It passes into breast milk in small amounts but is typically compatible with breastfeeding. Consult your healthcare provider for personalized advice based on your specific situation.
Interaction
- May increase levels of certain statins, increasing risk of muscle damage
- Can enhance effects of blood thinners like warfarin
- Possible interaction with ergot derivatives causing serious side effects
- May affect levels of anti-seizure medications like carbamazepine
- Can increase toxicity of theophylline when used together
- Potential interactions with certain heart medications and antifungals
Precaution
Use with caution in patients with liver disease, myasthenia gravis, or heart rhythm disorders. Patients with history of QT prolongation or taking medications that affect heart rhythm need careful monitoring. Some formulations contain components that may trigger allergic reactions. Prolonged use may lead to secondary infections due to disruption of normal bacterial flora.
Important Information
Erythromax is effective only for bacterial infections, not viral infections like colds or flu. Taking antibiotics unnecessarily can reduce their effectiveness. Take at evenly spaced intervals for consistent blood levels. Store at room temperature away from moisture and heat. If you develop severe diarrhea, skin rash, or yellowing of eyes/skin, seek medical attention immediately.
