Klacid La (Clarithromycin)

Clarithromycin works by binding to the 50S ribosomal subunit of susceptible bacteria, blocking the translocation step of protein synthesis. This inhibition halts bacterial growth, producing a bacteriostatic effect that allows the immune system to clear the infection.

The dose of clarithromycin is individualized by the prescribing clinician based on the type and severity of infection, patient age, weight, renal and hepatic function, and any concomitant medications. Only a qualified health professional should set the dosing regimen.

Safety data for clarithromycin in pregnancy and lactation are limited, and the product does not have a definitive pregnancy category. It should be used only when the potential benefit justifies any possible risk to the fetus or infant, and decisions should be made in consultation with a healthcare provider.

To order Klacid La, submit an enquiry on the product page at gnhindia.com specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including any cold‑chain requirements) and necessary import documentation.

Clarithromycin is often compared with azithromycin, another macrolide. Both share a similar mechanism, but clarithromycin generally has a broader spectrum against certain Gram‑positive organisms and a higher potential for drug‑drug interactions due to CYP3A4 inhibition. Azithromycin may have a longer half‑life and fewer gastrointestinal side effects, but the choice depends on infection type, resistance patterns and patient factors.

Klacid La should be stored at ambient temperature, below 25 °C, in its original packaging to protect it from moisture and direct sunlight. Keep the container tightly closed and out of reach of children. Do not store in bathrooms or near heat sources.

Klacid La is taken orally, usually with a full glass of water. It may be taken with or without food, although taking it with food can reduce gastrointestinal upset for some patients. The tablet or capsule should be swallowed whole and not crushed or chewed unless specifically instructed by a healthcare professional.

Serious risks include hepatotoxicity (signs of liver injury such as jaundice or dark urine), QT interval prolongation leading to arrhythmias, severe allergic reactions (rash, swelling, anaphylaxis), and Clostridioides difficile‑associated colitis presenting with persistent watery diarrhea. Patients should seek immediate medical attention if any of these symptoms develop.

Klacid La should not be used by individuals with a known hypersensitivity to clarithromycin, other macrolides, or any of the product’s excipients. It is also contraindicated in patients with a history of significant QT prolongation or ventricular arrhythmias unless the benefits outweigh the risks and appropriate monitoring is in place.
