Contraindications and Precautions for Doxycycline Use

Before starting doxycycline, discuss your medical history with your doctor. Doxycycline is unsuitable for pregnant or breastfeeding women due to potential harm to the fetus or infant. Avoid this medication if you have a known allergy to tetracyclines.

Liver and Kidney Impairment

Doxycycline requires careful consideration if you have liver or kidney problems. Your doctor will adjust the dosage or choose a different antibiotic if necessary. Regular monitoring of your liver and kidney function may be required during treatment.

Interactions with Other Medications

Doxycycline interacts with several medications, potentially reducing their effectiveness or increasing side effects. These include antacids, certain laxatives, and some blood thinners. Provide your doctor with a complete list of all medications, supplements, and herbal remedies you are taking.

Sun Sensitivity

Doxycycline increases your sensitivity to sunlight. Use sunscreen with a high SPF, wear protective clothing, and limit sun exposure during treatment to prevent sunburn.

Potential Side Effects

Common side effects include nausea, diarrhea, and stomach upset. Less common, but potentially serious, side effects include increased pressure in the skull (pseudotumor cerebri), esophageal irritation, and tooth discoloration in children. Report any unusual symptoms to your doctor immediately.

Specific Considerations

Condition Recommendation
Children under 8 years Generally avoided due to tooth discoloration risk.
Individuals with porphyria Contraindicated due to potential exacerbation of the condition.
Patients with myasthenia gravis May worsen muscle weakness; careful monitoring needed.

Medication Compliance

Complete the full course of doxycycline as prescribed, even if you feel better. Stopping treatment early can lead to antibiotic resistance and incomplete treatment of the infection.
