Doxycycline

Description

Doxycycline is a broad-spectrum antibiotic that belongs to the class of tetracyclines. It is used to treat various bacterial infections, including acne, Lyme disease, and respiratory tract infections.

Mechanism of Action
Doxycycline works by inhibiting protein synthesis in bacteria. It binds to the bacterial ribosome, which is responsible for protein production, and prevents the assembly of amino acids into proteins. This ultimately leads to the death of the bacterial cells.

Side Effects
Common side effects of doxycycline include:

– Nausea and vomiting
– Diarrhea
– Abdominal pain
– Headache
– Fatigue
– Sun sensitivity

Adverse Effects
Less common but more serious adverse effects of doxycycline include:

– Allergic reactions (anaphylaxis, angioedema)
– Increased risk of Clostridioides difficile (C. diff) infection
– Hepatotoxicity (liver damage)
– Photosensitivity (severe sunburn)
– Permanent tooth discoloration in children under 8 years old

Important Safety Information
Doxycycline is not recommended for:

– Pregnant or breastfeeding women
– Children under 8 years old
