This guide covers the product details, how clarithromycin works, administration information, potential side effects and precautions to discuss with a healthcare professional.
What Is Synclar 500 mg?
Synclar 500 mg is an oral antibiotic tablet containing clarithromycin. It is manufactured by Cipla Limited according to the product listing. Clarithromycin is classified as a macrolide antibiotic, a group of medicines used in the treatment of infections caused by susceptible bacteria.
The 500 mg strength refers to the amount of active ingredient contained in each tablet. This information helps distinguish this presentation from other clarithromycin strengths.
Synclar is the product name, whereas clarithromycin identifies its active pharmaceutical ingredient. Although different brands may contain the same active ingredient, their inactive ingredients, tablet appearance and packaging can vary.
The prescribed use of Synclar 500 mg depends on the infection being assessed and the instructions provided by the prescribing healthcare professional. It should not be selected or used independently based only on symptoms.
Synclar 500 mg Composition and Product Details
Each Synclar tablet delivers a measured 500 mg dose of clarithromycin alongside inactive excipients that help bind the tablet, preserve stability, and assist absorption in the digestive tract. Always inspect the outer carton and blister foil to verify the exact tablet count and inactive ingredients, particularly if you have known allergies or sensitivities to excipients such as lactose or specific film coatings.

What Is Synclar 500 mg Used For?
Synclar 500 mg contains clarithromycin, an antibiotic associated with the treatment of certain bacterial infections. The specific conditions for which clarithromycin may be prescribed depend on the identified or suspected bacteria, clinical assessment and applicable prescribing information.
Respiratory Tract Infections
Clarithromycin is included in medicine information for certain respiratory tract infections. These may involve bacterial infections affecting the lungs and other parts of the respiratory system.
The selection of an antibiotic depends on the suspected organism and its susceptibility. Respiratory symptoms alone do not establish that an antibiotic is appropriate.
Throat and Ear Infections
Certain bacterial throat infections and ear infections are included in clarithromycin medicine information. The type of infection and the bacteria involved are considered when a healthcare professional selects treatment.
A sore throat, earache or similar symptom does not automatically indicate a need for clarithromycin.
Skin and Soft Tissue Infections
Clarithromycin information also includes certain infections affecting the skin and underlying soft tissue. The relevant bacterial organisms and clinical presentation determine whether this ingredient is an appropriate option.
Other Prescribing Considerations
Clarithromycin is also included in specific treatment combinations for certain conditions involving Helicobacter pylori. Such treatment involves a prescribed combination of medicines rather than clarithromycin being considered independently.
The indications for an individual clarithromycin product should always be checked against its applicable prescribing information. Not every use associated with the active ingredient necessarily applies to every branded presentation.
How Does Clarithromycin Work?
Clarithromycin exerts its antibacterial effect by interfering directly with how bacterial cells build essential proteins. Inside bacterial cells, structures called ribosomes assemble amino acids into the proteins needed for survival, repair, and reproduction. Clarithromycin selectively binds to the 50S subunit of the bacterial ribosome, blocking the translocation step of protein synthesis.
Without the ability to produce vital proteins, susceptible bacteria stop multiplying, which allows the body’s natural immune defences to clear the remaining infection. At higher concentrations or against particularly sensitive organisms, the medicine can also directly kill the bacteria. Clinical effectiveness relies on accurate diagnosis and ensuring the targeted bacteria have not developed resistance to macrolide antibiotics.
How to Take Synclar 500 mg
Synclar 500 mg should be taken according to the instructions provided by the prescribing healthcare professional and the directions accompanying the supplied medicine.
The following administration points are relevant when reviewing clarithromycin tablets:
Tablet administration: Check the product instructions to confirm how the supplied tablet should be swallowed. Australian clarithromycin tablet information generally describes swallowing tablets whole with water.
Timing: Follow the prescribed dosing intervals. Taking doses at the instructed times helps maintain a consistent medication schedule.
Food considerations: Follow the food instructions provided with the specific formulation. Do not assume that instructions for a different clarithromycin product automatically apply to Synclar.
Missed dose: If a dose is missed, follow the accompanying medicine information or ask a pharmacist for guidance. Do not take an additional dose to compensate without appropriate instructions.
Treatment duration: Follow the prescribed duration. Do not independently shorten, extend or repeat the treatment.
💡 Tip
Synclar 500 mg Dosage Information
The appropriate Synclar 500 mg dosage cannot be determined from tablet strength alone. Clarithromycin dosing depends on the condition being treated, the patient’s circumstances and the prescribing instructions.
Why Dosage May Differ
A healthcare professional considers several factors when determining the prescribed amount and schedule.
These include the type and severity of the infection, the patient’s age, kidney function, other medical conditions and medicines being taken.
Kidney function is particularly relevant because clarithromycin dosage may require adjustment in people with significant renal impairment.
Missed Dose Guidance
If you forget a dose, check the medicine instructions or contact a pharmacist for advice. The next dose should not be doubled to replace a missed one.
Treatment Duration
The prescribed treatment period varies according to the condition and individual circumstances. Follow the complete instructions provided by the prescriber rather than using a duration taken from another product or an online dosage example.
There is no single Synclar 500 mg dosage schedule that should be assumed suitable for every patient.

Drug Interactions to Know About
Synclar 500 mg strongly inhibits a key liver enzyme called CYP3A4 as well as certain drug transport proteins, which means it can significantly raise blood levels of many other medicines. Always provide your doctor and pharmacist with a complete list of your prescription drugs, over the counter remedies, and herbal supplements before starting treatment.
Medicines That May Interact
Several clinically important interactions require strict management:
- Cholesterol lowering statins, especially simvastatin and lovastatin, which must not be taken alongside clarithromycin due to the risk of severe muscle breakdown
- Colchicine, used for gout, as combining these medicines can lead to dangerous toxicity
- Blood thinners such as warfarin and direct oral anticoagulants, where clarithromycin may heighten bleeding risk
- Heart rhythm medicines and other drugs known to prolong the QT interval, which increase the chance of serious arrhythmias
- Certain migraine treatments like ergotamine, sedatives such as oral midazolam, and specific calcium channel blockers
Some drug combinations are strictly contraindicated, while others require temporary dose adjustments or close clinical monitoring by your doctor.
❗ Important
Precautions Before Taking Synclar 500 mg
Certain medical circumstances need to be discussed before clarithromycin is prescribed.
Existing Medical Conditions
Tell the prescribing professional about any history of liver or kidney impairment, heart rhythm abnormalities, electrolyte disturbances or previous reactions to macrolide antibiotics.
A previous allergy reaction to clarithromycin or another ingredient in the formulation is particularly important.
Pregnancy and Breastfeeding
If you are pregnant, planning a pregnancy or breastfeeding, discuss the medicine with a healthcare professional before use. The decision requires consideration of the individual circumstances and available clinical information.
Antibiotic Resistance
Antibiotic resistance is an important consideration when using clarithromycin. Unnecessary or inappropriate antibiotic use can contribute to resistant bacteria.
The medicine should only be used for the condition and duration specified by the prescribing professional. It should not be shared with another person or used for a different illness.
Storage and Handling
Store Synclar 500 mg tablets in their original blister packaging until the moment you are ready to take a dose, as the foil protects the medicine from moisture and light. Keep the pack in a cool, dry place below 25 degrees Celsius, away from bathroom cabinets or windowsills. Store all medicines securely out of the sight and reach of children. Never use tablets past their expiry date or if the packaging appears damaged, and return unused medicines to your local pharmacy for safe disposal.
