Adjustments for Specific Patient Populations

Doxycycline dosage requires careful consideration for certain patient groups. Adjustments are often necessary to ensure safety and efficacy.

Renal Impairment

Reduce the dosage for patients with moderate to severe kidney disease. Consult appropriate renal dosing guidelines for precise adjustments based on creatinine clearance. Lower doses are usually recommended to prevent drug accumulation.

Doxycycline is generally avoided during pregnancy due to potential risks to the developing fetus. Alternative antibiotics are usually preferred. Use during breastfeeding should be carefully weighed against potential risks to the infant; monitoring is recommended.

Children

Doxycycline is generally not recommended for children under eight years old due to the risk of tooth discoloration. Safer alternatives are available for pediatric patients.

Older Adults

Older adults may be more susceptible to adverse effects. Start with a lower dose and monitor closely for any signs of toxicity. Consider potential interactions with other medications commonly used in this population.

Specific Medication Interactions

• Antacids containing aluminum or magnesium: Administer doxycycline at least two hours before or after these medications.
• Dairy products: Avoid consuming dairy products concurrently, as this can decrease absorption.
