Salmycin 250 Capsules

To reduce the development of drug-resistant bacteria and maintain the effectiveness of tetracycline hydrochloride and other antibacterial drugs, tetracycline hydrochloride should be used only to treat infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. …

• Adults Usual daily dose, 1 gram as 500 mg twice a day or 250 mg four times a day
• Higher doses such as 500 mg four times a day may be required for severe infections or for those infections which do not respond to the smaller doses

• Administration of adequate amounts of fluid with the capsule formulation of tetracycline is recommended to wash down the drug and reduce the risk of esophageal irritation and ulceration (see ADVERSE REACTIONS )
• Absorption of tetracycline is impaired by antacids containing aluminum, calcium or magnesium and preparations containing iron, zinc or sodium bicarbonate
• Food and some dairy products also interfere with absorption

See WARNINGS and DOSAGE AND ADMINISTRATION .

• Counsel patients that antibacterial drugs including tetracycline should only be used to treat bacterial infections
• They do not treat viral infections (e.g., the common cold)
• When tetracycline is prescribed to treat a bacterial infection, tell patients that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed
• Skipping doses or not completing the full course of therapy may decrease the effectiveness of the immediate treatment and increase the likelihood that bacteria will develop resistance and will not be treatable by tetracycline or other antibacterial drugs in the future

This drug is contraindicated in persons who have shown hypersensitivity to any of the tetracyclines.

Since bacteriostatic drugs may interfere with the bactericidal action of penicillin, it is advisable to avoid giving tetracycline in conjunction with penicillin or other bactericidal antibacterials. Because the tetracyclines have been shown to depress plasma prothrombin activity, patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage. Absorption of tetracyclines is impaired by antacids containing aluminum, calcium or magnesium and preparations containing iron, zinc, or sodium bicarbonate. Concurrent use of tetracycline may render oral contraceptives less effective.

Tooth Development The use of drugs of the tetracycline-class during tooth development (last half of pregnancy, infancy and childhood to the age of 8 years) may cause permanent discoloration of the teeth (yellow-gray-brown). This adverse reaction is more common during long-term use of the drugs but it has been observed following repeated short-term courses. Enamel hypoplasia has also been reported. Tetracycline drugs should not be used in this age group, except for anthrax, unless other drugs are not likely to be effective or are contraindicated. …

Gastrointestinal: anorexia, nausea, epigastric distress, vomiting, diarrhea, glossitis, black hairy tongue, dysphagia, enterocolitis, and inflammatory lesions (with Candida overgrowth) in the anogenital region. Esophagitis and esophageal ulceration have been reported in patients receiving particularly the capsule and also the tablet forms of tetracyclines. Most of the patients were reported to have taken medication immediately before going to bed (see DOSAGE AND ADMINISTRATION ). Teeth : permanent discoloration of teeth may be caused during tooth development. Enamel hypoplasia has been reported (see WARNINGS ). Skin : fixed drug eruption, maculopapular and erythematous rashes. …

Pregnancy Teratogenic Effects Pregnancy Category D (see WARNINGS ) Nonteratogenic Effects (see WARNINGS ) Pregnant women with renal disease may be more prone to develop tetracycline-associated liver failure.

In case of overdosage, discontinue medication, treat symptomatically and institute supportive measures. Tetracycline is not dialyzable.

Store at 20° to 25°C (68° to 77°F) [See USP Controlled Room Temperature].
