What are Klacid LA 500mg modified release tablets?
Klacid LA 500mg Modified Release Tablets contain clarithromycin, which is a macrolide antibiotic. They are designed to release the medicine slowly over time, rather than all at once.
This modified release design may help maintain medicine levels in the body for longer and can make once-daily dosing possible, depending on the prescription.
Klacid LA is used for certain bacterial infections, including infections of the respiratory tract, skin, and soft tissues, when prescribed by a healthcare professional.
How does Klacid work?
Clarithromycin works by inhibiting bacterial protein synthesis. In simple terms, it interferes with the bacteria’s ability to grow and multiply.
Because it is an antibiotic, Klacid LA is used for bacterial infections and is not effective against viral illnesses such as colds or flu.
The modified release formulation is intended to provide a slower, more controlled release of the active ingredient.
What is Klacid LA used for?
Based on the original content, Klacid LA may be prescribed for infections such as:
- Respiratory tract infections
- Pneumonia
- Bronchitis
- Sinusitis
- Skin infections
- Soft tissue infections
The exact use depends on the infection being treated and the prescriber’s assessment.
How is it usually taken?
The original content states that the usual adult dose may be 500mg once daily for mild to moderate infections, and that in some cases a higher dose may be used for more severe infections.
For children, dosing is based on body weight and the condition being treated. The exact dose should come from the prescriber or the official leaflet.
It is also stated that Klacid LA should be taken with food to help absorption and reduce stomach upset. Taking it at the same time each day may help with routine and adherence.
