Tadalafil Dr Reddy's: Price, Availability and How to Order in the UK
Published: 8 November 2026
Tadalafil Dr Reddys is one of several generic versions of Cialis available in the UK for treating erectile dysfunction. While Dr Reddy's Laboratories manufactures tadalafil for the UK market, availability of specific manufacturers can vary between pharmacies and over time. At Cured Pharmacy, we supply tadalafil from licensed UK manufacturers at prices starting from £7.95 (or £6.36 for your first order with code Ednew), following an online consultation reviewed by a UK prescriber.
At a glance
What is tadalafil Dr Reddys and how does it work?
Tadalafil is the active ingredient in Cialis, a prescription medicine used to treat erectile dysfunction in men [1]. Dr Reddy's Laboratories is an international pharmaceutical company that manufactures generic tadalafil alongside other well-known manufacturers such as Teva, Accord, and Mylan. All generic tadalafil products contain the same active ingredient and work in the same way, regardless of the manufacturer [4].
Tadalafil belongs to a group of medicines called PDE5 inhibitors. It works by relaxing blood vessels in the penis, allowing increased blood flow when you are sexually aroused [4]. Unlike some other ED treatments, tadalafil can remain effective for up to 36 hours after taking a dose, which is why it is sometimes called 'the weekend pill'. This does not mean you will have an erection for 36 hours; rather, you may be able to achieve an erection during this window when sexually stimulated [4].
Tadalafil is available in two forms: on-demand tablets (usually 10mg or 20mg taken at least 30 minutes before sexual activity) and daily low-dose tablets (2.5mg or 5mg taken once a day) [4]. The choice depends on how often you have sex and your personal preference, which your prescriber will discuss during your consultation.
Tadalafil Dr Reddys price: what affects the cost?
The price of tadalafil in the UK depends on several factors, including the manufacturer, the strength, the quantity ordered, and whether you choose branded Cialis or a generic version. Generic tadalafil from manufacturers such as Dr Reddy's, Teva, Accord, and others is significantly less expensive than branded Cialis because the original patent has expired and multiple companies can now produce the medicine [4].
At Cured Pharmacy, generic tadalafil starts from £7.95 per treatment, or £6.36 for your first order when you use code Ednew at checkout. This represents a 20% discount on your first purchase. The exact price depends on the strength you are prescribed (10mg or 20mg) and the quantity. Branded Cialis is also available at £12.00 (£9.60 with code Ednew) for those who prefer the original product [12].
It is important to note that while the manufacturer name may vary depending on stock availability, all generic tadalafil supplied by UK-registered pharmacies meets the same rigorous quality and safety standards set by the Medicines and Healthcare products Regulatory Agency (MHRA). Whether your prescription is dispensed as Dr Reddy's, Teva, or another licensed manufacturer, the active ingredient, strength, and effectiveness remain the same [12].
Why do prices vary between pharmacies?
Different pharmacies negotiate their own supply agreements with manufacturers and wholesalers, which can lead to price differences. Online pharmacies often have lower overheads than high-street branches, allowing them to offer competitive pricing. At Cured Pharmacy, we aim to provide transparent, affordable pricing with no hidden consultation fees, and our first-order discount code Ednew gives you 20% off to help you try the service.
How is tadalafil Dr Reddys supplied and what strengths are available?
Tadalafil is supplied as film-coated tablets in two main strengths for on-demand use: 10mg and 20mg. The usual starting dose is 10mg, taken at least 30 minutes before sexual activity [4]. Your prescriber may adjust this to 20mg if the 10mg dose is not effective enough, or reduce it to 5mg if you experience side effects. The maximum dose is one tablet per day [4].
For men who have sex more than twice a week, a daily low-dose option (2.5mg or 5mg) may be more suitable. This is taken once a day at the same time, allowing you to be ready for sexual activity at any time without needing to plan ahead [4]. Daily tadalafil can also be prescribed for men with both erectile dysfunction and urinary symptoms related to an enlarged prostate, though this use requires careful assessment by a prescriber [4].
Tadalafil tablets are usually supplied in blister packs. At Cured Pharmacy, your medicine will arrive in discreet, tamper-evident packaging with a dispensing label showing the medicine name, strength, dosage instructions, and expiry date. You will also receive a patient information leaflet that lists all possible side effects and safety information [12].
Can I choose a specific manufacturer?
While some patients ask for a specific manufacturer such as Dr Reddy's or Teva, availability depends on current stock. If you have a strong preference or have previously had a good experience with a particular brand, you can mention this in your online consultation. However, we cannot guarantee a specific manufacturer will always be available, as supply chains change. Rest assured that any generic tadalafil we dispense is fully licensed and meets UK quality standards [12].

Tadalafil Dr Reddys vs other ED treatments: how do they compare?
Tadalafil is one of four PDE5 inhibitors licensed in the UK for erectile dysfunction. The others are sildenafil (generic Viagra), vardenafil (generic Levitra), and avanafil (Spedra) [1][2]. Each works in a similar way but differs in how quickly it starts to work and how long the effect lasts.
Sildenafil is usually taken about one hour before sex and lasts for around four to six hours [3]. It is often the first treatment men try because it has been available the longest and is very affordable, starting from £0.45 per tablet at Cured Pharmacy (£0.36 with code Ednew). Vardenafil works in about 25 to 60 minutes and lasts a similar length of time to sildenafil [5]. Avanafil (Spedra) is the newest option and can work in as little as 15 to 30 minutes, though it is more expensive [6][11].
Tadalafil's main advantage is its long duration of action—up to 36 hours—which many men find gives them more spontaneity and less pressure to time sexual activity [4]. Some men prefer the shorter-acting medicines because they like the effect to wear off more quickly. Your prescriber will help you choose the most suitable option based on your lifestyle, other medicines, and any health conditions.
Who can take tadalafil and are there any interactions?
Tadalafil is suitable for most men over 18 with erectile dysfunction, but it is not safe for everyone [4]. You must never take tadalafil if you use nitrate medicines for chest pain (such as GTN spray, isosorbide mononitrate, or isosorbide dinitrate), nicorandil, riociguat, or recreational drugs called 'poppers' (amyl or alkyl nitrites). Combining tadalafil with any of these can cause a dangerous drop in blood pressure [4].
If you take alpha-blockers for an enlarged prostate or high blood pressure (such as tamsulosin, doxazosin, or alfuzosin), you may still be able to use tadalafil, but you must be stable on the alpha-blocker first and will usually start on the lowest dose of tadalafil. Your prescriber will check this carefully during your consultation [4]. Other blood-pressure medicines can also add to the blood-pressure-lowering effect of tadalafil, which may cause dizziness, but this is usually manageable [4].
Certain medicines that affect liver enzymes can alter tadalafil levels in your body. Potent CYP3A4 inhibitors—such as ritonavir, cobicistat (found in some HIV medicines), ketoconazole, itraconazole, and clarithromycin—can increase tadalafil levels, so your dose may need to be reduced [4]. Conversely, CYP3A4 inducers like rifampicin, carbamazepine, phenytoin, and St John's wort can make tadalafil less effective [4]. Always tell your prescriber about every medicine, supplement, and recreational drug you use.
When is tadalafil not suitable?
Tadalafil is not suitable if you have been advised by your doctor that sexual activity is inadvisable—for example, if you have had a recent heart attack or stroke, unstable angina, severe heart failure, very low blood pressure, or certain serious heart rhythm problems [4]. It is also not recommended if you have ever had sudden vision loss due to a condition called non-arteritic anterior ischaemic optic neuropathy (NAION), or if you have certain inherited retinal disorders [4]. Your prescriber will review your medical history to ensure tadalafil is safe for you.
When to get urgent help
- Erection lasting more than 4 hours (priapism) - go to A&E immediately
- Sudden loss of vision in one or both eyes - stop tadalafil and seek urgent medical help
- Sudden decrease or loss of hearing - stop tadalafil and see a doctor urgently
- Chest pain during or after sex - stop activity, do not take more tadalafil, call 999 if pain does not resolve
- Severe allergic reaction (swelling of face, lips, tongue, difficulty breathing) - call 999
Call 999 or go to A&E in an emergency, or contact NHS 111 for urgent advice.
How to order tadalafil Dr Reddys safely online at Cured Pharmacy
Ordering tadalafil online from Cured Pharmacy is straightforward, safe, and discreet. Because tadalafil is a prescription-only medicine, you will need to complete an online consultation before your order can be approved. This consultation asks about your symptoms, medical history, current medicines, and lifestyle to ensure tadalafil is safe and suitable for you [1][2].
Once you submit your consultation, it is reviewed by a UK-registered prescriber (a doctor or an independent prescriber pharmacist). If approved, your prescription is sent electronically to our pharmacy team, who will dispense and dispatch your medicine in plain, unmarked packaging. Most orders arrive within one to three working days. If the prescriber has any concerns or needs more information, they will contact you before issuing a prescription.
Your first order is eligible for a 20% discount when you use code Ednew at checkout, reducing the price of generic tadalafil to £6.36. You can choose the quantity that suits you, and there are no hidden consultation fees. If tadalafil is not suitable, the prescriber may suggest an alternative such as sildenafil or refer you back to your GP for further assessment. We encourage all men experiencing new or worsening erectile dysfunction to see their GP, as ED can be an early warning sign of conditions such as diabetes or heart disease [1][2].
What happens if I need to change my treatment?
If you find that tadalafil does not work well for you, or if you experience side effects, you can request a follow-up consultation to discuss alternatives. Many men try more than one type of PDE5 inhibitor before finding the one that suits them best. Our prescribers can adjust your dose, switch you to a different medicine, or provide advice on other options. You should never take more than the prescribed dose or combine tadalafil with another ED medicine [4].
Take tadalafil consistently
Tadalafil works best when taken as prescribed. If the first dose does not work, try it on at least four to six separate occasions before considering a dose change or switching treatments.
