Generic Name: tetracycline (tet-ra-SYE-kleen)
Brand Name: Sumycin
Tetracycline suspension is used for:
Treating infections caused by certain bacteria. It is also used to treat certain types of acne and used along with other medicines to treat amoeba infections. It may also be used for other conditions as determined by your doctor.
Tetracycline suspension is a tetracycline antibiotic. Tetracyclines slow the growth of sensitive bacteria by interfering with the production of proteins needed by the bacteria to grow. Slowing the bacteria's growth allows the body's defense mechanisms (eg, white blood cells) to destroy them.
Do NOT use tetracycline suspension if:
- you are allergic to any ingredient in tetracycline suspension
- you have a sulfite allergy
- you are taking acitretin, isotretinoin, or a penicillin
Contact your doctor or health care provider right away if any of these apply to you.
