As with other antibiotics, treatment with tetracycline can cause secondary bacterial or mycotic infections (fungal). There is in particular the possibility of resistant staphylococcal enterocolitis (inflammation of the small intestine and colon due to bacteria that are resistant to the therapeutic action of the drug). Should you undergo cycles of prolonged treatment with Tetralysal, your doctor will prescribe regular checks of blood composition and liver and kidney function. Take the medicine with adequate amounts of water to avoid irritation or ulceration of the esophagus. Children Tetralysal should not be used in children under 8 years because of the risk of permanent alterations of tooth and enamel discoloration.

You should tell your doctor if you are taking any treatment with lithium, this medicine may increase the lithium levels.

Avoid use with penicillins (another type of antibiotics), for the possible interference between the two products.
