Klacid Sr (Clarithromycin)

Clarithromycin works by binding to the bacterial 50S ribosomal subunit, which blocks the elongation of the peptide chain during protein synthesis. This inhibition stops bacterial growth, allowing the immune system to clear the infection. The action is bacteriostatic against most susceptible organisms.

The dosage of Klacid Sr is determined by the prescribing clinician based on the infection type, severity, patient age, weight, and renal or hepatic function. Healthcare professionals follow established guidelines and adjust the regimen as needed for optimal therapeutic effect.

Safety data for clarithromycin in pregnancy and lactation are limited. It should be used only if the potential benefit justifies the potential risk to the fetus or infant. Women who are pregnant, planning pregnancy, or breastfeeding should discuss risks and alternatives with their healthcare provider.

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.

Klacid Sr (clarithromycin) offers a broader spectrum against certain Gram‑positive organisms compared with azithromycin, and it has a longer half‑life allowing twice‑daily dosing. However, clarithromycin has a higher potential for drug‑drug interactions due to CYP3A4 inhibition, whereas azithromycin is less likely to interact but may be less effective for some resistant strains.

Klacid Sr should be stored at room temperature, below 25 °C, in its original packaging to protect it from moisture and excessive heat. Keep the product out of reach of children and avoid exposing it to direct sunlight or humid environments.

Klacid Sr is taken orally, usually with a full glass of water. It can be taken with or without food, although taking it with food may reduce gastrointestinal upset. The exact administration schedule is set by the prescriber.

Serious risks include severe allergic reactions such as anaphylaxis or Stevens‑Johnson syndrome, Clostridioides difficile‑associated colitis, liver injury, and cardiac effects like QT prolongation that can lead to arrhythmias. Patients should seek immediate medical attention if they experience rash, persistent diarrhea, jaundice, or palpitations.

Klacid Sr should not be used by individuals with a known hypersensitivity to clarithromycin, other macrolides, or any component of the formulation. It is also contraindicated in patients taking drugs that can cause serious cardiac arrhythmias when combined with clarithromycin, such as cisapride, ergot alkaloids, or pimozide.
