Adults typically receive a daily dose of 100-200 mg, while children’s dosages are calculated based on body weight. It can be taken with or without food, but drinking a full glass of water with it helps reduce esophageal irritation. Consistency in medication schedule is essential for optimal results.

Contraindications and Precautions

Doxycycline is contraindicated in individuals with known hypersensitivity to tetracyclines. Caution is advised in patients with liver impairment or a history of candidiasis overgrowth. It is not recommended for children under 8 years old due to the potential for permanent tooth discoloration and impact on bone development.

Drug Interactions

Concurrent use of doxycycline with anticoagulants, penicillins, antacids, or iron supplements can affect the efficacy of either doxycycline or the other medications. Consultation with a healthcare provider is crucial to avoid potential interactions.

Adverse Reactions

While generally well-tolerated, some patients may experience gastrointestinal discomfort such as nausea and vomiting, as well as photosensitivity leading to an increased risk of sunburn.

Warnings and Precautions

Sun exposure should be minimized during doxycycline treatment due to its photosensitizing potential. Prolonged use may lead to superinfection by resistant organisms, and patients with renal impairment require close monitoring.

Pregnancy and Lactation

Doxycycline is typically avoided during pregnancy, particularly in the second and third trimesters, due to potential risks to the fetus’s dental and bone growth. Caution is also advised during breastfeeding as it can pass into breast milk.

Overdose and Symptoms

Overdose symptoms may include nausea, vomiting, and diarrhea. Immediate medical attention is necessary in case of suspected overdose, with supportive care and symptomatic treatment being the mainstays of management.

Storage and Handling

Doxycycline should be stored at room temperature away from light and moisture. Tablets and capsules should be kept in their original package until use to protect from elements. Oral suspension should be discarded after the expiration date or if not used within a specific timeframe after reconstitution, according to manufacturer recommendations.

Patient Counseling Information

Patients should be informed about the importance of completing the entire prescribed course of doxycycline, even if feeling better, to prevent the development of resistant bacteria. Additionally, they should be briefed about the risk of photosensitivity and advised on the importance of using sun protection.
