Sumycin (Tetracycline) Tablets: Prices, Strengths, and Package Options

We carry Sumycin, the brand-name tetracycline antibiotic, as oral tablets in two strengths: 250 mg in 180- or 360-tablet packages, and 500 mg in 90-, 120-, 180-, 270-, or 360-tablet packages. Because tetracycline is usually prescribed as a defined course rather than an open-ended supply, choosing the right strength, tablet count, and package size matters as much as comparing unit prices. This guide walks through the real choices available in our catalogue, explains what drives value across pack sizes, and places those decisions alongside the practical details of using tetracycline safely.

Throughout this page we focus on the exact strengths, package quantities, and prices we currently offer, rather than general estimates. Separate parts of this listing cover full specifications, regulatory classification, and frequently asked questions, so this guide concentrates on helping you weigh price, quantity, and clinical fit together.

Comparing our package sizes and unit value

Unit price is one of the clearest ways to compare tablet packs, but it only tells part of the story. A larger pack lowers the cost per tablet, yet it only represents good value if it matches the quantity directed for your treatment, fits your realistic storage window, and will be used before the expiry date printed on the package. We built the comparison below specifically to show how total price and per-tablet value move together across the 250 mg pack sizes we stock.

Use this comparison as a starting point rather than a shortcut to the largest pack available. A lower unit cost is useful only when the quantity aligns with your prescribed regimen and does not leave an unnecessary surplus of antibiotics.

Which Sumycin strength and package size fits your treatment plan?

We offer Sumycin as 250 mg tablets in two pack sizes and as 500 mg tablets across a wider range of quantities. The right strength depends on the dose your prescriber has set, not on price alone. Although two 250 mg tablets contain the same total amount of tetracycline as one 500 mg tablet, do not change the strength or number of tablets per dose without confirming the substitution with a prescriber or pharmacist.

To assess quantity, start with the exact number of tablets per dose, doses per day, and treatment days in your directions. The resulting total can be compared with the available package sizes, but it should not be increased merely to obtain a lower unit price or to keep tablets for a possible future infection. If the available quantity does not align with your directions, ask a prescriber or pharmacist how to proceed.

If your prescribed regimen changes, our range of package sizes at each strength lets you select the closest appropriate option rather than being limited to a single fixed quantity.

Brand-name Sumycin, generic tetracycline, and related antibiotics

Sumycin is a brand name for tetracycline in tablet form, and tetracycline is also available generically under its own name. Choosing Sumycin over a generic tetracycline tablet is primarily a question of brand preference and the exact packaging available, since both share the same active ingredient, dosage form, and route.

Tetracycline belongs to a broader family of related antibiotics. We also carry Doxycycline, another tetracycline-class antibiotic that some prescribers favour for once- or twice-daily dosing and a somewhat different food interaction profile. For patients who cannot take any tetracycline-class drug, Erythromycin is a macrolide alternative sometimes used for comparable indications. If you are exploring the wider antibiotic range, our Antibiotics category brings together these and other options in one place.

What Sumycin tetracycline is used for

Tetracycline is a broad-spectrum antibiotic prescribed for selected susceptible bacterial infections, including some respiratory and urinary tract infections, moderate inflammatory acne, and chlamydia in an appropriate regimen. Tetracycline has also been used for gonorrhea historically, but it is not routine first-line treatment for gonorrhea in Canada because resistance is common; any such use requires current susceptibility information and professional direction.

• Moderate to severe inflammatory acne, generally as a time-limited systemic-antibiotic course within a broader acne treatment plan
• Chlamydia infections when a prescriber selects an appropriate tetracycline regimen
• Other bacterial infections where susceptibility testing or clinical judgment supports tetracycline

Because the exact dose, course length, and combination with other medicines depend on the infection being treated, the specific regimen should always follow your prescriber's instructions rather than a generic schedule.

How does tetracycline work, and how should it be taken?

Tetracycline works by binding to the bacterial ribosome's 30S subunit, which blocks bacteria from making the proteins they need to grow and multiply. This bacteriostatic action gives the immune system the opportunity to clear the remaining infection as bacterial numbers stop increasing. Clinical improvement for many acute infections may become noticeable within a few days, while acne treatment generally requires several weeks before visible improvement. Lack of improvement or worsening symptoms should be assessed rather than managed by extending the course without advice.

Administration matters more with tetracycline than with many other antibiotics. It is usually taken on an empty stomach, at least one hour before or two hours after meals, because food, dairy products, and calcium-, magnesium-, iron-, or aluminum-containing supplements and antacids can reduce how much tetracycline the body absorbs.

• Take each dose with a full glass of water and avoid lying down immediately afterward, since tetracycline can irritate the esophagus
• Separate doses from milk, yogurt, antacids, and iron or calcium supplements by at least two hours
• Take the medicine for the prescribed duration, even if symptoms improve early, unless a prescriber tells you to stop or change treatment
• Store tablets at 20°C to 25°C in a tightly closed, light-resistant container, away from excess heat and moisture, and discard any tablets once they pass their expiry date

Safety, precautions, and interactions to be aware of

Tetracycline carries well-established precautions alongside its established benefits. It is contraindicated in pregnancy, since it crosses the placenta and, when used in the second or third trimester, can permanently discolour a developing baby's teeth, affect enamel formation, and temporarily inhibit bone growth. For the same reasons, tetracycline passes into breast milk and is generally avoided during breastfeeding, and it is not used in children under 8 years of age because it can permanently discolour developing teeth.

• Known hypersensitivity to tetracycline or related tetracycline-class antibiotics is a contraindication
• People with diabetes should monitor blood glucose closely, since tetracyclines can potentiate insulin and oral hypoglycemic medicines
• Oral retinoids such as isotretinoin are generally not combined with tetracycline because the combination can increase the risk of intracranial hypertension
• Anticoagulant treatment may require closer monitoring because tetracycline can increase anticoagulant effects in some patients
• Increased sun sensitivity can occur, so sunscreen and protective clothing are advisable during treatment
• Dizziness or visual disturbances such as blurred vision can occur; anyone affected should avoid driving or operating machinery until these resolve
• Common adverse effects include nausea, diarrhea, and, less often, a sense of fullness or indigestion

Severe headache with visual changes, signs of an allergic reaction, or severe or persistent diarrhea requires prompt medical assessment. This overview is general medical information rather than a personal recommendation, and anyone with specific health conditions, other medicines, or planned pregnancy should discuss their exact regimen with a prescriber or pharmacist before starting or continuing tetracycline.

What should Canadian customers know about prescription status and ordering?

Tetracycline is authorised for human medicinal use in Canada, and oral tetracycline tablets such as Sumycin are classified as a prescription medicine under Canadian regulation. That classification describes how the dosage form is regulated nationally; it is separate from what we require to process an order through our checkout.

Under our ordering policy, we do not require a prescription to accept an order for Sumycin, so customers can order tetracycline tablets through us without submitting one first. This reflects our own ordering process rather than a change to tetracycline's prescription classification in Canada, and we still encourage anyone starting treatment to confirm the correct strength, dose, and course length with a prescriber or pharmacist.

Ordering, support, and delivery with us

We have operated as an online pharmacy catalogue since 2018, and our support team is available 24/7 by email and online chat, with a pharmacist on hand to answer questions about Sumycin or any other product in our catalogue.

• Select your preferred Sumycin strength and package size at checkout, where the exact option and price are confirmed before payment
• Reach our support team by email or online chat at any hour if you have questions about a pack size, your order status, or general product information
• Expect your chosen package to arrive through our standard delivery process, which you can review at checkout alongside any applicable delivery timelines
• When the order arrives, confirm the strength and tablet count against your selection and contact our support team if the package is damaged or does not match the order
• Keep an eye on the printed expiry date, and store tablets as directed rather than in a bathroom cabinet exposed to heat and moisture

Choosing the Sumycin option that fits your course and budget

The package-value comparison above gives you the exact prices and per-tablet costs across our 250 mg Sumycin packs, and similar reasoning applies when comparing 500 mg package sizes: a larger package may lower the unit price, but it delivers real value only when its tablet count aligns with the quantity directed for your treatment and the medicine can be stored correctly within its expiry date. Rather than treating the lowest unit price as the only consideration, weigh it alongside your prescribed strength, dose frequency, treatment duration, and storage plans, then select the package size at checkout that most closely matches the quantity you are expected to use.
