Clarithromycin 500mg Tablets
SKU GME997Product Introduction
Clarithromycin 500mg is a macrolide antibiotic used for susceptible respiratory, throat, sinus and skin infections. It also forms part of selected Helicobacter pylori eradication regimens and treatment for certain mycobacterial infections. Its usefulness depends on the organism and local resistance, not simply on the presence of a cough or sore throat.
How to use
Swallow the conventional tablet with water, with or without food; food may reduce nausea. Keep doses evenly spaced through the treatment day and complete the planned course. These tablets should not be confused with once-daily extended-release clarithromycin, which has different administration instructions.
How it works
Clarithromycin binds to the bacterial 50S ribosomal subunit and inhibits protein synthesis. This prevents susceptible bacteria from producing proteins needed for growth and survival.
Side effects
Nausea, diarrhoea, abdominal discomfort, headache and an altered or metallic taste can occur. Severe watery or bloody diarrhoea, jaundice, a blistering rash, palpitations or fainting needs urgent attention.
Important information
Tell your doctor about prolonged QT interval, low potassium or magnesium, coronary disease, kidney impairment, liver injury from previous clarithromycin, pregnancy and breastfeeding. Simvastatin, lovastatin, colchicine, domperidone, some antiarrhythmics and several other medicines can have serious interactions. The dose may need reduction in substantial kidney impairment.
Uses
- Susceptible bacterial respiratory, sinus, throat and skin infections
- combination H. pylori eradication
- selected mycobacterial infections.
Benefits
Clearing a susceptible bacterial infection can reduce fever, pain and local inflammation. In an effective H. pylori combination regimen, eradication can support ulcer healing and reduce recurrence; clarithromycin alone does not provide that complete regimen.
Can Clarithromycin 500mg eradicate H. pylori by itself?
No. It is used with other suitable medicines, usually including acid suppression and another antibiotic. Previous macrolide exposure and resistance can affect whether a clarithromycin regimen is appropriate.
Is a metallic taste a recognised effect?
Yes. Taste disturbance is a recognised clarithromycin adverse effect and usually resolves after treatment. Severe intolerance or inability to eat or drink should be reported.
Can I replace these tablets with an extended-release version at the same schedule?
No. Conventional and extended-release products have different dosing intervals and food instructions. The release type must match the intended regimen.
What if the infection is not improving after a few days?
The cause, bacterial sensitivity and possible complications need reassessment. Taking extra tablets or extending the course independently will not overcome every form of resistance.
