Cialis Black: UK Status, Risks & the Licensed Equivalent

Written by Suks Minhas, MBBS, MD, FRCS(Urol) · Last updated

Cialis Black does not have MHRA approval for sale in the UK. It can still show up in some listings, but the MHRA has not assessed its safety or effectiveness.

Check with a pharmacist before using any unlicensed product, and verify a seller's registration before buying. A seller who is vague about licensing status should not be assumed to mean approval.

Not UK-licensed. This medicine is not supplied through UK-registered pharmacies.

Sellers list the active ingredient as tadalafil (claimed). The MHRA has not assessed what these products actually contain.

UK-licensed equivalent: Tadalafil

The MHRA warns that medicines sold outside registered pharmacies can be counterfeit, contaminated, or contain the wrong amount of active ingredient. Buy prescription-only medicines from a pharmacy registered in the UK.

as of Oct 2, 2026 · Pricing methodology

Treat any price here as an estimate, drawn from UK pricing sources including NHS dispensing data, not a price any one pharmacy has promised. Actual prices vary by pharmacy, pack and location, so confirm the exact price with the pharmacy before you buy. A price well below the listed range should raise a red flag about who is actually selling it.

About Cialis Black

Cialis Black is not a licensed medicine in the United Kingdom and cannot legally be sold there as a medicine. Its ingredients, quality and claimed effects may not have been independently checked by the medicines regulator. Adults considering treatment for erectile difficulties can discuss licensed tadalafil with a doctor or pharmacist, who can assess suitability and safer options.

Claimed strengths are manufacturer claims, but no strength is listed for Cialis Black. No dosing schedule or instruction is provided here.

The absence of a listed strength makes the product contents and appropriate amount uncertain. A doctor or pharmacist can discuss a licensed tadalafil product and suitable use.

What Cialis Black is used for

Cialis Black is marketed for erectile difficulties and is claimed to help an adult obtain or maintain an erection for sexual activity. This is a marketing claim, not an established medical benefit for this product. Erectile difficulties can have several causes, including health conditions and medicines.

A doctor or pharmacist can help assess the cause and discuss licensed treatment options. Cialis Black should not be used as a substitute for medical assessment, particularly if erection problems are new, persistent or linked with other symptoms.

How Cialis Black works

Tadalafil belongs to a group of medicines called phosphodiesterase type five inhibitors. This class supports the natural erection response by helping blood vessels in the penis relax when sexual stimulation occurs. This can increase blood flow and make an erection easier to obtain or maintain.

Sexual stimulation is still needed; these medicines do not usually cause an erection on their own. Cialis Black is not classified as a licensed medicine, so the amount and contents of any product sold under this name may not be reliable or independently checked.

Key warnings

  • Cialis Black is not a licensed medicine in the United Kingdom and cannot legally be sold there as a medicine.
  • The product's contents, strength and quality have not been independently verified.
  • PDE5 inhibitors can cause a fall in blood pressure, dizziness, headache, flushing, indigestion or changes in vision.
  • Chest pain during sexual activity needs urgent medical attention.
  • A prolonged or painful erection needs urgent medical attention.
  • Extra caution is needed with heart or blood pressure problems and with medicines that lower blood pressure.

Main interactions

  • Nitrate medicines used for chest pain can cause a dangerous fall in blood pressure when combined with tadalafil-type medicines.
  • Riociguat can interact with this medicine class and may lower blood pressure excessively.
  • Alpha-blockers and other blood pressure medicines can increase the risk of dizziness or low blood pressure.
  • Other medicines in the PDE5 inhibitor class should not be combined with tadalafil-type treatment.
  • Some medicines that affect liver enzymes can change tadalafil levels in the body.
  • Large amounts of alcohol may increase dizziness and the risk of low blood pressure.

Missed dose

A missed dose depends on whether tadalafil has been prescribed for occasional or regular use. A replacement amount should not be taken to make up for a missed dose, and doses should not be doubled.

For an unlicensed product, the contents and dosing instructions may not be reliable. A doctor or pharmacist can give product-specific advice for licensed tadalafil and explain what to do after a missed dose.

Pregnancy and breastfeeding

The marketing material does not specify pregnancy data for Cialis Black. Tadalafil-type medicines are not generally intended for use during pregnancy.

It is also unclear whether an unlicensed product contains what its packaging claims. Anyone who is pregnant, planning pregnancy or breastfeeding should discuss this with a doctor or pharmacist before considering tadalafil or any product sold as Cialis Black.

Storage

No storage conditions are listed for Cialis Black. Keep the product in its original packaging, away from moisture and excessive heat, and out of the sight and reach of children.

Follow any storage directions on the label to maintain quality. A pharmacist can advise if the packaging is damaged or storage conditions are unclear.
