Generic tetracycline is a broad-spectrum antibiotic that inhibits bacterial protein synthesis. It’s used for acne, respiratory infections, and certain sexually transmitted diseases. Because the patent has expired, manufacturers can produce it at a fraction of the brand‑name cost, making it a popular choice for budget‑conscious patients.
The active ingredient in both brand‑name and generic versions is the same molecule: tetracycline hydrochloride. The difference lies in excipients, packaging, and price. In the UK, the MHRA (Medicines and Healthcare products Regulatory Agency) ensures that any product labelled "generic" meets the same quality, safety, and efficacy standards as the original.
Typical dosage for adults is 250‑500mg every 6hours, taken on an empty stomach. A standard 28‑tablet pack costs around £2‑£4 when sourced from a reputable online pharmacy, versus £15‑£20 for a branded equivalent.
In Britain, tetracycline is classified as a prescription‑only medicine (POM). That means you need a valid prescription from a qualified prescriber before any pharmacy-online or brick‑and‑mortar-can dispense it.
The General Pharmaceutical Council (GPhC) and the MHRA jointly regulate online pharmacies. Look for the UK registered pharmacy logo and a valid registration number on the site’s footer. If the site claims to sell tetracycline without a prescription, it’s likely operating illegally and the product may be sub‑standard.
When you’ve narrowed the list, request a copy of the patient information leaflet (PIL) for the exact generic product. Legitimate sellers will provide it instantly.
Product | Typical Price (28 tablets) | Prescription Status | Spectrum of Activity | Common Uses |
---|---|---|---|---|
Generic tetracycline | £2‑£4 | POM | Broad‑spectrum (Gram‑positive & Gram‑negative) | Acne, respiratory, chlamydia |
Brand‑name Tetracycline (e.g., Tetracyn) | £15‑£20 | POM | Same as generic | Same as generic |
Doxycycline (generic) | £5‑£7 | POM | Broad‑spectrum, better GI tolerance | Acne, Lyme disease, malaria prophylaxis |
As the table shows, the cheapest way to get the same active ingredient is through a genuine generic. Doxycycline is an alternative if you experience stomach upset; it’s slightly pricier but still far below the brand name.
If anything feels off-missing batch number, unfamiliar imprint, or a price that looks too good to be true-contact the pharmacy’s support line before taking a dose.
Tetracycline can cause photosensitivity, upset stomach, and, rarely, liver toxicity. To minimise risks:
Keep a short diary of how you feel each day. If side effects become severe, stop the medication and seek medical advice immediately.
Understanding the broader context helps you make informed choices:
Each of these areas deepens your understanding of safe antibiotic use and helps you avoid common pitfalls when purchasing online.
No. Tetracycline is a prescription‑only medicine. Any site offering it without a valid prescription is operating outside UK law and may be selling counterfeit products.
A legitimate UK‑registered online pharmacy typically charges between £2 and £4 for a standard 28‑tablet pack, excluding any shipping fees.
Common side effects include nausea, diarrhoea, and photosensitivity. Rare but serious reactions are liver inflammation and severe allergic rash. Stop the drug and seek medical help if you notice yellowing of the skin or persistent vomiting.
No. Calcium binds to tetracycline and reduces absorption. Take the medication on an empty stomach and avoid dairy, calcium supplements, or antacids for at least one hour before and two hours after each dose.
Check the pharmacy’s registration number on the GPhC website, look for the UK registered pharmacy logo, read recent reviews, and ensure the site uses HTTPS for checkout. A legitimate pharmacy will also provide a copy of the patient information leaflet on request.
Macrolides (e.g., azithromycin) or sulfonamides can be suitable alternatives, depending on the infection. Consult your doctor for a tailored prescription.
