It is not effective against viral infections and should not be used for common colds or influenza.

How it is dosed

Doses and duration are chosen by the prescriber according to the infection and patient factors. Adult regimens frequently fall between 100 mg and 200 mg per day. This can be given once daily or split into two doses about 12 hours apart.

Practical points to follow:

• Swallow tablets or capsules with a full glass of water to reduce the risk of throat or esophageal irritation.
• Taking doxycycline with food can reduce stomach upset; however avoid taking it close to milk, calcium supplements or iron unless the product advises otherwise.
• Remain upright for at least 30 minutes after dosing to lower the chance of esophageal problems.
• Do not crush, chew or open delayed-release tablets or capsules; take them whole.
• If you use an oral suspension, shake the bottle and use an accurate measuring device provided with the medicine.
• Separate dairy products or antacids containing calcium, magnesium or aluminium, and iron supplements by 2 to 3 hours from doxycycline if instructed for your formulation.

Always complete the full prescribed course unless your clinician tells you otherwise.

Steps for safety and precautionary actions

• Dental and bone considerations: Use in children during tooth development may cause permanent tooth staining; routine use is usually avoided in children under 12 unless a specialist recommends it.
• Photosensitivity: Doxycycline can increase sensitivity to ultraviolet light. Use sun protection and suitable clothing while taking it and for a short period afterwards.
• Tracking: For extended treatment courses, clinicians may request periodic checks of liver and kidney function and full blood counts.
• Esophageal care: Drink water with each dose and avoid lying down immediately after taking the medicine to reduce the risk of irritation.
• Pregnancy and nursing: The drug is generally avoided in pregnancy and lactation; discuss risks and optional choices with a clinician before taking it.
• Driving and operating machinery: If you become dizzy or experience visual disturbance, avoid driving or operating machines until you know how the medicine affects you.

Conditions that rule out its use

• Known allergy to doxycycline or any tetracycline antibiotic
• Pregnancy, especially beyond early pregnancy, unless specifically recommended by a specialist
• Breastfeeding without medical advice
• Young children in the period of tooth development, typically under 12 years, unless directed by a specialist
• Severe impairment of hepatic capacity
• Certain rare blood disorders or porphyria unless under specialist care

Unfavorable outcomes

Most patients tolerate doxycycline, but side effect risks do occur. Common and important adverse reactions include:

• Gastrointestinal upset: nausea, vomiting, abdominal discomfort or diarrhea
• Headache pain, dizziness or temporary visual changes
• Increased tendency to sunburn or develop a sun-sensitive rash

Essential drug the act of interactions fuel collaboration and innovation. checks

• Antacids and mineral supplements containing aluminium, magnesium, calcium, iron or zinc can reduce doxycycline absorption; space these by 2 to 3 hours if advised.
• Warfarin is one example of an anticoagulant medication. may have altered effects; performance monitoring of clotting tests may be needed when antibiotics are started.
• Some anticonvulsants and enzyme inducers (for example phenytoin, carbamazepine, phenobarbital) can lower doxycycline levels.
• Systemic retinoids are not recommended together because of a potential increase in intracranial pressure.
• Combining doxycycline with beta-lactam antibiotics can be antagonistic against some organisms; only use together if the prescriber specifies.
• Oral contraceptive reliability is not usually directly reduced by doxycycline, but vomiting or severe diarrhea could impair contraceptive absorption so use extra safety precautions when appropriate.

Actions to take after missing a dose

If a dose is skipped, take it when you remember. If the next dose is due soon, skip the failure to take a dose and continue with the usual schedule. Do not take a double amount to replace a failure to take a dose.

• Tetracycline - an older member of the same class
• Macrolides such as azithromycin or clarithromycin - often used for respiratory infections and some STIs
• Beta-lactams like amoxicillin or amoxicillin-clavulanate - used for many dental, skin and respiratory infections when appropriate

• Metronidazole - for anaerobic infections and particular dental or skin conditions; also used in some rosacea regimens
