I want to give you a genuinely practical answer here because the price difference between the most expensive and cheapest places to buy common medicines in London is remarkable, and I think most students are overpaying without realizing it.

The Core Point: Supermarket Own-Brand Is Always Cheaper Than Pharmacy-Branded
I'd start with this principle because it underlies everything else: a box of branded paracetamol (like Panadol or Nurofen) costs several times more than the identical active ingredient in a supermarket own-brand or pharmacy own-brand product. The ingredient is the same; 500 mg of paracetamol is 500 mg of paracetamol regardless of the packaging. You are paying for the brand name, not better medicine.
The Cheapest Option: Supermarket Own-Brand
Aldi, Lidl, Tesco, and Sainsbury's all sell their own-brand paracetamol and ibuprofen at prices that are genuinely very low compared to high street pharmacies. A pack of 16 Aldi or Lidl paracetamol tablets typically costs around 25p. The same quantity of Panadol at Boots could cost 15 to 20 times more. I'd encourage you to genuinely compare next time you're in both shops.
For antihistamines, cold and flu remedies, antacids, and other common over-the-counter medicines, the supermarket own-brand versus branded gap is similarly large. I'd always check the supermarket's own-brand shelf before buying anything at a pharmacy.
Poundland, Savers, and Home Bargains: Worth Knowing About
These discount shops stock a range of generic over-the-counter medicines at low prices comparable to supermarket own-brands. Poundland and Savers in particular carry paracetamol, ibuprofen, antihistamines, and cold remedies at prices that are consistently lower than Boots or Superdrug.
Boots and Superdrug: When They're Worth Using
I wouldn't avoid Boots and Superdrug entirely; they have their own advantages. Both carry a much wider range of medicines than a typical supermarket, including products for more specific conditions. Both operate loyalty points programs (Boots Advantage Card, Superdrug Health and Beautycard) that build up usable points over time. And both frequently have three-for-two or multibuy offers on own-brand products that can genuinely be competitive.
For prescription collection, contraception, and specific pharmaceutical advice, Boots and Superdrug pharmacies are staffed by registered pharmacists who can give you personalised guidance that a supermarket till can't.
The Pharmacist: A Genuinely Underused Free Resource
I'd specifically want you to know this: the pharmacist at any Boots, Superdrug, or independent pharmacy is a qualified healthcare professional who can give you free, personalised advice about which medicine is appropriate for your symptoms without an appointment. You can walk in, describe your symptoms, and they'll recommend the right product and check for any interactions with anything else you're taking.
This service is completely free and often faster than trying to get a GP appointment for a minor ailment. I'd use pharmacists more and GPs for minor things less; it frees up GP appointments for situations that genuinely need them.
Online: Amazon and Other Platforms for Bulk Buying
For medicines you take regularly, like antihistamines if you have hay fever, for example, buying in bulk through Amazon or a reputable online pharmacy can reduce the per-dose cost significantly. I'd only do this for medicines I know I take and know are appropriate for me, rather than for new symptoms I haven't had assessed.

Frequently Asked Questions
Where is the cheapest place to buy paracetamol in London?
Aldi's and Lidl's own-brand paracetamol are consistently the cheapest options, typically around 25p for 16 tablets. Supermarket own-brands at Tesco and Sainsbury's are similarly priced. All are significantly cheaper than branded equivalents at high street pharmacies.
Is supermarket own-brand medicine as effective as branded pharmacy medicine?
Yes. Over-the-counter medicines contain the same active ingredients regardless of brand. Supermarket own-brand paracetamol contains the same 500mg of paracetamol as Panadol. You're paying for the packaging and brand name, not a better product.
Can I ask a pharmacist for advice without an appointment?
Yes. Pharmacists at Boots, Superdrug, and independent pharmacies can give you free, personalized advice about which medicine is appropriate for your symptoms without any appointment. This is a genuinely useful and underused free service.
Is Boots cheaper than Superdrug for medicines in London?
They're broadly comparable, with both significantly more expensive than supermarket own brands for common medicines. Both have loyalty programs and regular multibuy offers that can reduce costs. For everyday paracetamol and ibuprofen, a supermarket's own brand is consistently cheaper than either.
Should I buy medicines online to save money?
For medicines you take regularly and know are appropriate for you, buying in bulk online can reduce the per-dose cost. I'd only buy online when I'm familiar with the medicine and its appropriate use, not for new symptoms that haven't been assessed.
