IQ Doctor discount code
£45 off an eligible first order with DYWELCOME. It is typed in rather than applied for you, so the promo box at checkout is where this saving is won or quietly lost.
New customers at IQ Doctor
One tap copies DYWELCOME to your clipboard and opens IQ Doctor in a new tab. Paste it into the discount, promo or voucher field at checkout and confirm the total has fallen by £45 before you pay.
Offer terms last checked 4 September 2026. Eligible first orders only; IQ Doctor sets its own account, basket and checkout conditions. Treatment is subject to an online assessment and clinical approval, and a code is never a guarantee that treatment will be prescribed to you.
One code, one customer type
DYWELCOME is a new customer code. If you have ordered from IQ Doctor before, expect it to be refused rather than to fail silently, and do not read that refusal as the site being broken. Providers usually run separate returning customer offers that are worth less, so if you are already a patient, ask what is available to you rather than assuming the headline figure applies.
Why IQ Doctor appears on Dayo
A code only counts if the pharmacy behind it is registered and traceable. IQ Doctor publishes its own GPhC registration, and the record is linked below rather than described.
GPhC verified pharmacy
Registration 9010411, checked on the official register
Maintenance friendly
Supports treatment at lower maintenance BMIs
Dayo Verified
Premises and certificates manually checked
Patient reviews of delivery and support sit on the IQ Doctor Trustpilot profile. Read those alongside the registration record: an inspection tells you how a pharmacy is run, a review tells you how the parcel arrived, and you want both answers.
How ordering through IQ Doctor works
Copy the code and open the service
The button above copies DYWELCOME and opens IQ Doctor in a new tab. Leave that tab open. You will not need the code until the final screen, and clipboards get overwritten by whatever you copy in between.
Complete the online assessment
You answer questions about your weight history, health conditions and current medicines, and IQ Doctor’s clinical team reviews your answers before any prescription-only decision is made. Answer to inform rather than to pass: the assessment is there to catch the cases where treatment would do you harm, and being declined means it worked.
Paste DYWELCOME and read the total
Enter DYWELCOME in the discount field at checkout and confirm £45 has come off. Check the delivery charge and the repeat order price in the same glance, because a first order saving tells you nothing about what month two costs.

About IQ Doctor
IQ Doctor is a UK online pharmacy service built around an assessment pathway: you complete the provider’s questions, a clinical team reviews suitability, and only then is a prescription-only treatment decision made. It publishes pharmacy registration number 9010411 with the General Pharmaceutical Council, and the badge above opens that entry on the regulator’s own site so you can confirm it rather than take our word for it.
For questions about an order, a consultation, an account or a delivery, contact IQ Doctor on 0121 752 7584 or at [email protected]. Dayo cannot see your order or account, so provider questions go to the provider; we can only re-check the listing itself.
Does DYWELCOME apply to oral weight loss treatment?
The code is a first order saving on eligible orders rather than a discount attached to one named treatment, so it is not restricted to a single route by design. Which treatment can be prescribed to you, tablet or injection, is decided by the clinical team after your assessment and depends on what is suitable for you and available at the time. Ask during the consultation rather than assuming, and read our tablet versus injection guide first so you can weigh the answer when it comes.
Using DYWELCOME properly
- Nothing happens unless you paste it. This is a typed code, not an automatic link discount, and forgetting to enter it is the single most common way a saving disappears.
- New customers only. Budget for the standard price from your second order onwards, and check whether the service reorders on a cycle.
- Enter it exactly. A trailing space copied along with the code is enough to have it rejected, and the error message rarely tells you that is the reason.
- Check the discount lands before paying. If £45 does not come off, do not complete the order, and tell us through our contact page so we can re-check the listing.
- Compare the discounted total, not the discount. £45 off a higher price can still lose to a cheaper provider. Our discount price list and retail price list compare the true cost at checkout.
- Price the step you will settle at. Tablet treatment escalates through six steps and cost usually rises as you move up; see our steps guide.
- A code is not eligibility. Whether treatment suits you is a clinical decision; start with our BMI and eligibility guide.
Our commercial disclosure
Dayo may earn a commission if you order after following the link on this page, at no cost to you. Commission does not affect ranking or inclusion: our tables are ordered by price, and a provider that does not meet our verification standards is removed. At least 20% of relevant surplus is committed to UK charities under our charity pledge. Full detail in our independence statement.
Before you order anywhere
Treatment of this kind is prescription only and available privately rather than on the NHS. Prices, codes, eligibility criteria and delivery terms all change, sometimes weekly in a newly launched market, so treat the figures here as a starting point and confirm everything at the provider’s own checkout before paying. If any provider offers prescription treatment without a clinical assessment, walk away and read our fake pharmacy guide.
