Doxycycline treats various bacterial infections. Its broad-spectrum activity makes it useful for a wide range of conditions.
Common Infections Treated with Doxycycline
- Acne vulgaris: Doxycycline reduces inflammation and bacterial load, improving acne symptoms. Dosage typically ranges from 40-100mg daily. Respiratory tract infections: It’s effective against Mycoplasma pneumoniae and Chlamydia pneumoniae, causing atypical pneumonia. Usual dosage is 100mg twice daily. Sexually transmitted infections (STIs): Doxycycline is a first-line treatment for chlamydia and gonorrhea infections, often prescribed as a single dose or a short course. Lyme disease: It’s part of the standard treatment regimen for early Lyme disease, usually administered for 10-21 days. Other infections: Doxycycline also treats rickettsial infections (like Rocky Mountain spotted fever), ehrlichiosis, and some types of cholera.
Important Prescribing Information
Patient history: Thoroughly assess for allergies, pregnancy, breastfeeding, and liver or kidney problems. Doxycycline can cause photosensitivity, so sun protection is crucial. Drug interactions: Doxycycline interacts with several medications, including antacids, certain antibiotics, and oral contraceptives. Always review the patient’s medication list for potential conflicts. Dosage adjustments: Dose adjustments may be necessary for patients with renal or hepatic impairment. Always consult relevant guidelines. Monitoring: Monitor for side effects, including nausea, vomiting, diarrhea, and esophageal irritation. Advise patients to take the medication with plenty of water and avoid lying down immediately afterward. Compliance: Ensure patient understanding of the prescribed regimen, including duration of therapy. Proper adherence is essential for treatment success.
Specific Considerations for Certain Patient Groups
- Pregnancy and breastfeeding: Use is generally avoided during pregnancy and breastfeeding due to potential fetal harm. Alternatives should be considered. Children: Doxycycline is generally not recommended for children under 8 years due to potential tooth discoloration. Alternatives are usually preferred. Elderly patients: Renal function often declines with age, necessitating dosage adjustments to prevent toxicity.
