Avalon® 30 ml PFS
DESCRIPTION: Avalon® 30 ml PFS contains Azithromycin. It is an Azalide, a subclass of macrolide antibiotics active against Gram-positive and Gram-negative organisms. Azithromycin is derived from Erythromycin. Azithromycin interferes with ribosome function in susceptible bacteria by inhibiting the translocation of peptides.

CONTRAINDICATIONS: Azithromycin is contraindicated in patients hypersensitive to Azithromycin or any other macrolide antibiotic. Co-administration of ergot derivatives and Azithromycin is contraindicated. Azithromycin is contraindicated in patients with hepatic diseases.
SIDE EFFECTS: Azithromycin is well tolerated with a low incidence of side effects. Majority of the side effects were mild to moderate in nature and of gastrointestinal in origin with nausea, abdominal discomfort, vomiting, flatulence and diarrhea. Allergic reactions such as rash have occurred and there have also been rare reports of serious hypersensitivity reactions. Reversible elevations in liver transaminases have been seen with a frequency similarly to the comparative macrolides and penicillins used in clinical trials. Transient mild reductions in neutrophil counts have occasionally been observed in clinical trials, although a causal relationship to Azithromycin has not been established.
PRECAUTIONS: As with any antibiotic, observation for signs of super infection with no susceptible organisms, including fungi recommended. No dose adjustment is needed in patients with renal impairment.
USE IN PREGNANCY AND LACTATION: Animal reproduction studies have demonstrated that Azithromycin crosses the placenta, but have revealed no evidence of harm to the fetus. There are no adequate and well-controlled studies in pregnant women. Since animal reproduction studies are not always predictive of human response, Azithromycin should be used during pregnancy only, if adequate alternatives are not available. No data on secretion of Azithromycin in breast milk is available. So, Azithromycin should only be used in lactating women where adequate alternatives are not available.
OVERDOSAGE: There is no data on overdosage with Azithromycin. Typical symptoms of overdosage with macrolide antibiotics include hearing loss, severe nausea, vomiting and diarrhoea. Gastric lavage and general supportive measures are indicated.
STORAGE CONDITIONS: Store in a cool and dry place, away from light and children.
Avalon® 30 ml PFS: Dry powder in glass bottle for reconstitution into 30ml of suspension. After reconstitution each 5ml contains Azithromycin Dihydrate equivalent to 200mg Azithromycin.
