Achromycin® is the brand name of an antibiotic used to treat a variety of bacterial infections. It is also known by its generic name, tetracycline. The medication is often used as a treatment for infections of the respiratory system, skin — including acne — and urinary tract. Although it may have other uses, antibiotics are not prescribed for colds, the flu, or other viral conditions.
When used to treat acne, Achromycin® usually comes as a liquid solution that is applied directly to the affected skin. For other conditions, it can be taken orally or intravenously. While the medication sometimes has side effects, including diarrhea, upset stomach, and increased sensitivity to the sun, most are considered minor. People with certain health conditions or who take other medications may not be able to use Achromycin®.
To use Achromycin® for acne, one should apply it directly to the affected skin using the hands or an applicator that may be included with the prescription. In some cases, the medication may cause irritation, stinging, or burning of the skin, though side effects may decrease with continued use of the drug. Consult a doctor if these side effects become persistent or bothersome, or if more serious side effects develop. Achromycin® may also cause yellow staining of the skin, which can usually be removed by rinsing with water. Before using other acne medications in conjunction with Achromycin®, a person is advised to speak with a doctor to help avoid drug interactions.
When used in its oral or intravenous form, Achromycin® can make birth control pills less effective, and a backup method of contraception may be needed. While most side effects are not serious, a doctor should be notified right away about worrisome side effects such as difficulty breathing, blurred vision, or jaundice symptoms. In some cases, Achromycin® should not be taken with blood thinners or antacids. People with health conditions including diabetes, kidney or liver disease, or medication allergies should ask a doctor before taking this antibiotic.
As with most antibiotics, it is important to follow the dosage instructions for Achromycin® and to finish all of the medication. In some cases, an infection can remain in the body after symptoms disappear, and not finishing a course of antibiotics can produce resistant strains of bacteria. Do not share medication with others; antibiotics should only be used by the person for whom they are prescribed. Only a doctor can ensure that antibiotics are the appropriate treatment for a given illness.
