Sumycin

Sumycin (tetracycline hydrochloride) is a broad-spectrum tetracycline-class antibiotic indicated for the treatment of various bacterial infections. It works by inhibiting protein synthesis in susceptible bacteria, thereby stopping their growth and spread. This medication is prescribed for conditions including respiratory tract infections, urinary tract infections, and acne, among others. Proper usage under medical supervision ensures optimal therapeutic outcomes while minimizing risks.

Features

• Active ingredient: Tetracycline hydrochloride
• Available in 250 mg and 500 mg capsules
• Broad-spectrum activity against Gram-positive and Gram-negative bacteria
• Inhibits bacterial protein synthesis at the ribosomal level
• Requires prescription; not available over-the-counter

Benefits

• Effectively treats a wide range of bacterial infections
• Reduces severity and duration of infection symptoms
• Helps prevent complications from untreated bacterial conditions
• Can be used for both acute and chronic bacterial infections
• Supported by decades of clinical use and research

Common use

Sumycin is commonly prescribed for bacterial infections such as pneumonia, bronchitis, sinusitis, urinary tract infections, skin and soft tissue infections, and acne vulgaris. It is also used in the management of sexually transmitted infections like chlamydia, and for certain rickettsial diseases and zoonotic infections. Off-label uses may include periodontal disease and Helicobacter pylori eradication in combination therapy.

Dosage and direction

Dosage is individualized based on the infection type, severity, patient age, and renal function. For adults, the typical dose is 500 mg twice daily or 250 mg four times daily. For severe infections, an initial dose of 1 gram followed by 500 mg every 12 hours may be prescribed. Take on an empty stomach (1 hour before or 2 hours after meals) with a full glass of water. Do not lie down for at least 10 minutes after taking. Complete the full course even if symptoms improve.

Precautions

Avoid dairy products, antacids, or iron supplements within 2–3 hours of taking Sumycin, as they can reduce absorption. Use sunscreen and protective clothing due to increased photosensitivity. Not recommended during tooth development (last half of pregnancy, infancy, childhood up to age 8) due to risk of tooth discoloration. Use with caution in patients with renal impairment; dosage adjustment may be necessary.

Contraindications

Hypersensitivity to tetracycline or any component of the formulation. Contraindicated in patients with systemic lupus erythematosus. Do not use during pregnancy or in children under 8 years of age due to risk of permanent tooth discoloration and inhibition of bone growth.

Possible side effect

Common side effects may include nausea, vomiting, diarrhea, epigastric distress, glossitis, dysphagia, enterocolitis, and inflammatory lesions with monilial overgrowth in the anogenital region. Photosensitivity, rash, and urticaria may occur. Rare but serious side effects include pseudotumor cerebri, hepatotoxicity, and blood dyscrasias. Discontinue if severe diarrhea, headache, or visual disturbances occur.

Drug interaction

Antacids containing aluminum, calcium, or magnesium; iron preparations; and bismuth subsalicylate can impair absorption. May potentiate the effect of oral anticoagulants. Concurrent use with retinoids may increase risk of pseudotumor cerebri. Barbiturates, carbamazepine, and phenytoin may decrease tetracycline levels. Penicillins may interfere with the bactericidal action of tetracyclines.

Missed dose

If a dose is missed, take it as soon as remembered unless it is almost time for the next dose. Do not double the dose to catch up. Maintain the regular dosing schedule to ensure consistent antibiotic levels.

Overdose

Symptoms may include nausea, vomiting, and diarrhea. No specific antidote exists; management is supportive. Gastric lavage may be considered if ingestion was recent. Hemodialysis does not significantly remove tetracycline.

Storage

Store at room temperature (15–30°C or 59–86°F) in a tightly closed container. Protect from light, moisture, and excessive heat. Keep out of reach of children and pets. Do not use after the expiration date.

Reviews

Clinical studies and decades of use support the efficacy of Sumycin for indicated infections when used appropriately. Patient experiences vary; many report effective resolution of bacterial symptoms when the full course is completed as directed. Consult your physician for information specific to your condition.
