Doxycycline may produce gastrointestinal irritation to a varying degree in some but not all individuals. Epigastric distress, abdominal discomfort, may occur. Long term therapy with doxycycline may produce hematological changes. Various skin reactions including rashes, urticaria, exfoliative dermatitis may follow the use of Doxycycline but they are rare.

The use of drug of tetracycline group during tooth development (last half of pregnancy, infancy and childhood to the age of 12 years) may cause permanent discoloration of the teeth. Tetracyclines, therefore, should not be used in these age groups unless other drugs are not likely to be effective or are contraindicated.

Hypersensitivity to any of the tetracyclines contraindicates the use of Doxycycline.
