Levofloxacin Info

What Is Levofloxacin?

Levofloxacin belongs to the fluoro-quinolone class of antibiotics. It works by stopping certain bacteria from multiplying, helping the body clear infections. In Hong Kong, levofloxacin is available in several products, including the well-known brand Levaquin and generic levofloxacin tablets or oral suspensions.

Medicines That Contain Levofloxacin

Levofloxacin is marketed in Hong Kong under a few names:

• Levaquin - a brand-name tablet that comes in 250 mg, 500 mg and 750 mg strengths.
• Levofloxacin (generic) - sold by local pharmacies and hospitals as tablets, oral suspensions (often 100 mg/5 ml), and occasionally as eye drops for specific eye infections.

These formulations may be supplied alone or combined with other agents in fixed-dose products for particular infections. All are regulated by the Hong Kong Department of Health under the Medicines and Poisons Ordinance.

What Conditions Does Levofloxacin Treat?

Levofloxacin is commonly prescribed for a range of bacterial infections. Typical uses include:

• Respiratory tract infections such as community-acquired pneumonia, acute exacerbations of chronic bronchitis and sinusitis.
• Urinary tract infections (UTIs), including uncomplicated cystitis and more complex kidney infections.
• Skin and soft-tissue infections, for example cellulitis or infected wounds.
• Prostatitis (infection of the prostate gland).
• Certain eye infections when supplied as ophthalmic drops, like bacterial conjunctivitis.

The drug is chosen because it covers many of the bacteria that cause these illnesses, offering an option when first-line antibiotics are unsuitable.

How Does Levofloxacin Work?

Levofloxacin interferes with the bacteria’s ability to replicate their DNA. By blocking this essential step, the bacteria can’t grow or spread, allowing the immune system to eliminate the remaining organisms. Effects usually start within a day, but the full benefit may take a few days depending on the infection type.

Safety and Side Effects

Common Side Effects

• Mild stomach upset, nausea or diarrhea.
• Headache or dizziness that usually resolves on its own.
• Slight increase in sensitivity to sunlight (photosensitivity).

These reactions are generally temporary and do not require medical attention unless they become severe.

Serious Reactions

• Allergic reactions such as rash, swelling of the face or throat, or trouble breathing. Seek emergency care if these appear.
• Tendon problems, especially tendon rupture in the shoulder, elbow, wrist, knee, or ankle. Stop the medication and get medical help if you notice sudden tendon pain.
• Severe gut inflammation (Clostridioides difficile-associated diarrhoea). Persistent watery stools with abdominal cramping should be reported promptly.

Who Should Be Cautious

• People with a history of tendon disorders or recent corticosteroid use.
• Individuals with known hypersensitivity to fluoro-quinolones.
• Pregnant or breastfeeding women should avoid levofloxacin unless a specialist advises otherwise.

Interaction Awareness

Levofloxacin may interact with:

• Other medicines such as antacids containing aluminium or magnesium, some heart-rhythm drugs, and certain anti-seizure medications.
• Alcohol and caffeine, which can increase the feeling of nervousness or tremors.
• Foods high in calcium or iron, which may reduce absorption if taken at the same time.

For a full list of possible interactions, refer to the specific product’s information leaflet.

Things to Keep in Mind

Store levofloxacin tablets and suspensions at room temperature, away from moisture and direct sunlight. Keep medicines out of reach of children. Treatment courses are usually short, ranging from a few days for uncomplicated infections to up to two weeks for more serious conditions. Always follow the directions printed on the product label, as formulations and strengths differ between Levaquin and generic levofloxacin.

For detailed usage, dosing, and administration, refer to the information provided with your specific medication.
