Monitor for reduced efficacy of the tetracycline if these products are used concomitantly. Consider therapy modification
Retinoic Acid Derivatives: Tetracyclines may enhance the adverse/toxic effect of Retinoic Acid Derivatives. The development of pseudotumor cerebri is of particular concern. Exceptions: Adapalene; Bexarotene (Topical); Tretinoin (Topical). Avoid combination
Sodium Picosulfate: Antibiotics may diminish the therapeutic effect of Sodium Picosulfate. Management: Consider using an alternative product for bowel cleansing prior to a colonoscopy in patients who have recently used or are concurrently using an antibiotic. Consider therapy modification
Strontium Ranelate: May decrease the serum concentration of Tetracyclines. Management: In order to minimize any potential impact of strontium ranelate on tetracycline antibiotic concentrations, it is recommended that strontium ranelate treatment be interrupted during tetracycline therapy. Avoid combination
Sucralfate: May decrease the absorption of Tetracyclines. Management: Administer most tetracycline derivatives at least 2 hours prior to sucralfate in order to minimize the impact of this interaction. Administer oral omadacycline 4 hours prior to sucralfate. Consider therapy modification

Separate dose administration of oral tetracycline derivative and oral zinc salts by at least 2 hours to minimize interaction. Exceptions: Zinc Chloride. Consider therapy modification
1% to 10%: Gastrointestinal: Nausea (3%)
<1%, postmarketing, and/or case reports: Vulvovaginal candidiasis, vulvovaginal infection
Concerns related to adverse effects:
- CNS effects: Lightheadedness, dizziness, and vertigo may occur; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving). Symptoms usually disappear with continued therapy and when the drug is discontinued.
- Intracranial hypertension: Intracranial hypertension has been associated with use of tetracyclines; headache, blurred vision, and/or papilledema may occur. Women of childbearing age who are overweight are at greater risk. Concomitant use of isotretinoin (known to cause intracranial hypertension) and sarecycline should be avoided. Intracranial hypertension typically resolves after discontinuation of treatment; however, permanent visual loss is possible. If visual symptoms develop during treatment, prompt ophthalmologic evaluation is warranted.
- Photosensitivity: May cause photosensitivity; discontinue if skin erythema occurs. Use skin protection and avoid prolonged exposure to sunlight; do not use tanning equipment.
- Superinfection: Prolonged use may result in fungal or bacterial superinfection, including Clostridioides (formerly Clostridium) difficile-associated diarrhea(CDAD) and pseudomembranous colitis; CDAD has been observed >2 months postantibiotic treatment.
- Pediatric: May cause tissue hyperpigmentation, tooth enamel hypoplasia, or permanent tooth discoloration (more common with long-term use, but observed with repeated, short courses) when used during tooth development (last half of pregnancy, infancy, and childhood ≤8 years of age).
- Pregnancy: Do not use during pregnancy. In addition to affecting tooth development, tetracycline use has been associated with retardation of skeletal development and reduced bone growth.
Ophthalmologic evaluation if visual disturbances occur
Tetracyclines accumulate in developing teeth and long tubular bones. Permanent discoloration of teeth (yellow, gray, brown) can occur following in utero exposure and is more likely to occur following long-term or repeated exposure. Reversible inhibition of bone growth may occur following maternal use of tetracyclines in the second and third trimesters. Sarecycline should be discontinued immediately if pregnancy occurs during treatment.
- Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
- Patient may experience nausea or diarrhea. Have patient report immediately to prescriber sunburn, severe dizziness, passing out, signs of Clostridium difficile (C. diff)-associated diarrhea (abdominal pain or cramps, severe diarrhea or watery stools, or bloody stools), headache, blurred vision, double vision, or blindness (HCAHPS).
- Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
