Tetracycline — Compare Prices at US & Canada Pharmacies
Compare real Tetracycline prices at US and Canadian pharmacies, see official FDA uses and warnings, and find generic alternatives. Save up to 80% by comparing Canada pharmacy prices.
Tetracycline is the original drug in the tetracycline class — doxycycline and minocycline are newer, longer-acting relatives in the same family, not the same drug. All three share the class's core risks (tooth staining in children, photosensitivity), but tetracycline itself is dosed more frequently and is used less often today than doxycycline for most infections.
How much does tetracycline cost without insurance?
A standard course (500 mg, 56 capsules) ranged from about $47 to $91 across the pharmacies in our data — a real spread for the identical generic prescription, so comparing a couple of pharmacies before filling is worth doing.
Is there a generic version of tetracycline?
Yes — tetracycline has been generic for a long time, and the original brand (Sumycin) has been discontinued in the US. The generic is the only version generally available today.
Do I need a prescription to buy tetracycline?
Yes, in both the US and Canada. It's not available over the counter.
How can I save on tetracycline?
Comparing pharmacies directly is the main lever for a generic this cheap — the price spread we found for the identical 56-capsule prescription was nearly double between the lowest and highest pharmacy. A free discount card frequently beats an insurance copay for a drug in this price range.
"As low as" figures compare the single lowest oral tablet/capsule price found on each side — not necessarily the same strength or pack size. Always check the full tables below for your exact dose. Prices updated 2026-08-21.

What is Tetracycline used for?
Tetracycline was one of the first broad-spectrum antibiotics ever brought to market, and while newer relatives in its own drug class — doxycycline especially — have largely replaced it for most everyday infections (better absorption, less frequent dosing, fewer GI side effects), tetracycline itself is still prescribed for acne, some respiratory and skin infections, and as one component of combination therapy for H. pylori stomach infections.
It's taken multiple times a day on an empty stomach, which is a real practical downside compared to doxycycline's once- or twice-daily dosing — a large part of why doxycycline has become the more commonly prescribed drug in this class for new prescriptions, even though tetracycline itself still works well against susceptible bacteria.
Like every drug in the tetracycline class, it should not be used in children under 8 or during the second half of pregnancy, because it can permanently discolor developing teeth and, at high doses, has been linked to a serious liver reaction in pregnancy.
How Tetracycline works
Enters the bacterial cell
Tetracycline is actively transported into susceptible bacteria, reaching concentrations inside the cell higher than in the surrounding environment.
Blocks the bacterial ribosome
It binds the 30S subunit of the bacterial ribosome, physically blocking the next building-block (aminoacyl-tRNA) from attaching during protein synthesis.
Bacteria stop growing (bacteriostatic)
Without new proteins, bacteria can't grow or divide — tetracycline mainly halts bacterial growth rather than killing bacteria outright, relying on your immune system to clear the stalled infection.
Typical dosage forms & strengths
| Use | Typical adult dose | Form |
|---|---|---|
| Most infections (adults) | 250–500 mg, two to four times daily on an empty stomach | Capsule |
| Acne (longer-term, lower dose) | 250–500 mg once or twice daily | Capsule |
| Children 8 and older | Weight-based (mg/kg/day), divided into 2–4 doses | Capsule |

Warnings & interactions
This is a summary of the official FDA label text, not personalized medical advice. It does not list every possible interaction or side effect. Always tell your prescriber and pharmacist about every medicine and supplement you take.
Common, usually mild
- Nausea, stomach upset (more common than with doxycycline since it's taken on an empty stomach)
- Diarrhea
- Sun sensitivity (sunburn more easily than usual)
- Sore mouth or tongue
Serious — seek care promptly
- Severe headache with vision changes (rare intracranial pressure increase)
- Yellowing of skin or eyes (liver effect, more of a concern at high doses or in pregnancy)
- Severe or watery diarrhea (possible C. diff)
- Signs of an allergic reaction: hives, facial/throat swelling, trouble breathing
Contraindications
CONTRAINDICATIONS This drug is contraindicated in persons who have shown hypersensitivity to any of the tetracyclines.
Warnings
WARNINGS 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.
Notable drug interactions
| Drug / substance | What can happen |
|---|---|
| Calcium, magnesium, iron, and antacids (including dairy products) | Bind to tetracycline in the gut and substantially block its absorption — take tetracycline at least 1–2 hours apart from these. |
| Oral contraceptives | Classically counseled to reduce effectiveness; evidence is mixed but a backup method during treatment is a reasonable, low-cost precaution. |
| Warfarin and other blood thinners | Tetracycline can enhance the anticoagulant effect — more frequent monitoring may be advised. |
| Digoxin | In some people, tetracycline alters gut bacteria in a way that increases digoxin absorption, raising digoxin levels — relevant mainly for long-term tetracycline users also on digoxin. |
Pregnancy & breastfeeding
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.
