Fake Keytruda (Pembroluzimab) Is Flooding Pakistan

Cancer patients in Pakistan are being sold fake Keytruda vials for a few thousand rupees. A genuine vial of this drug costs between Rs 200,000 and Rs 550,000 and must travel through a licensed, refrigerated supply chain to reach a patient safely. What patients are receiving from grey markets and Instagram sellers contains no active ingredient at all.

This guide covers how counterfeit Keytruda enters Pakistan, what doctors are witnessing in clinics, and exactly what patients and families can do to verify every vial before an infusion begins. In this piece, we’ve discussed key points, including:

• Genuine Keytruda 100mg costs Rs 200,000 to Rs 550,000 per vial in Pakistan. Fakes are being sold for a few thousand rupees.
• Oncologists in Karachi have seen patients arrive with cloudy, particle filled vials labelled as Keytruda purchased through informal channels.
• DRAP has already approved pembrolizumab pricing. A federal cabinet notification delay is the only reason legal importation is still blocked.
• Instagram and Facebook are now active platforms for selling fake cancer drugs directly to Pakistani patients.
• A US federal court sentenced an Indian national to 43 months in prison in 2026 for selling fake Keytruda he admitted was just like water.
• DRAP testing found that 50% of medication samples across Pakistan were fake or substandard.
• Patients can verify Keytruda through DRAP’s official portal and Merck Pakistan before any infusion.
• The Pakistan Medical Association has formally declared the shortage of registered oncology drugs a humanitarian crisis.

What Is Keytruda and Why Counterfeiters Target It

Keytruda is the brand name for pembrolizumab, a cancer immunotherapy developed by Merck and approved by the U.S. Food and Drug Administration. It works by blocking the PD-1 receptor on cancer cells, which allows the patient’s immune system to recognise and attack tumours. It is one of the most widely used cancer drugs in the world.

Keytruda is used to treat a broad range of cancers, including:

• Melanoma (skin cancer)
• Non-small cell lung cancer
• Head and neck squamous cell carcinoma
• Bladder cancer and cervical cancer
• Hodgkin lymphoma and breast cancer
• Gastric and oesophageal cancer

A single box of eight 50mg pembrolizumab vials costs approximately $17,000 in the United States. In Pakistan, one genuine 100mg injection costs between Rs 200,000 and Rs 550,000. That enormous price tag makes Keytruda one of the most counterfeited oncology drugs in the world.

Fake Keytruda in Pakistan: What Doctors Are Seeing

Senior oncologists across Pakistan are regularly seeing patients who bring in Keytruda vials purchased from grey markets for a few thousand rupees. A Karachi oncologist told The News Pakistan in 2025 that the vials had cloudy solutions, visible floating particles, and less liquid than a real dose should contain. These are clear signs of a falsified medicine that was never manufactured in a licensed facility.

Patients who received these counterfeit vials showed no clinical benefit. Their cancers kept growing while they believed they were receiving treatment. By the time doctors detected the failure, months of irreplaceable treatment time had already been lost.

The physical warning signs of a fake Keytruda vial include:

• Cloudy or discoloured liquid inside the vial
• Visible floating particles in the solution
• A fill level visibly below the standard 4ml volume
• Inconsistent or low quality label printing
• No DRAP registration number on the outer packaging
• A price far below the Rs 200,000 to Rs 550,000 genuine market range

Why Legitimate Keytruda Cannot Be Legally Imported in Pakistan Yet

DRAP has already finalised pembrolizumab pricing and endorsed it at multiple regulatory levels. Pharmaceutical companies cannot legally import and market Keytruda in Pakistan because the federal cabinet has not yet issued a formal notification to complete the process. That single administrative step is the only thing blocking the entire authorised supply chain.

While the paperwork sits unactioned, black market operators have completely filled the gap. Pakistan Chemists and Druggists Association chairman Abdul Samad Budhani told The News that pharmacies are approached daily by patients seeking medicines not registered for legal sale in the country. The Pakistan Medical Association has called this situation a humanitarian crisis and urged the government to expedite approvals and act against those running the illegal drug trade.

Currently, patients are switching to alternative pembroluzimab products like:

• Pembroxim (Beacon Pharmaceuticals)
• Pemomab (Ziska Pharmaceuticals)
• Brolizum (Icepta Pharmaceuticals)

How Counterfeit Keytruda Enters Pakistan’s Drug Market

Fake Keytruda enters Pakistan through two main routes. The first is local: unregistered factories in unmarked industrial units produce counterfeit injectables in packaging designed to look exactly like Merck’s product. According to a 2025 PLoS One study on counterfeit drugs in Pakistan, more than 100,000 companies manufacture and sell drugs in Pakistan with no registration and no regulatory oversight whatsoever.

The second route is international. Smuggling networks move falsified pembrolizumab through transit hubs like Dubai to hide the country of manufacture before shipments reach Pakistani markets. Once inside the country, corrupt wholesalers distribute these products into pharmacies, clinics, and hospital procurement chains.

Key entry points for fake cancer drugs into Pakistan include:

• Unregistered local factories in Karachi, Lahore, and other cities
• Cross border smuggling from Afghanistan
• International shipments transiting through Dubai and other commercial hubs
• Corrupt wholesalers supplying pharmacies and hospital distributors
• Online sellers operating through Instagram, Facebook, and WhatsApp

Instagram and Social Media Selling of Fake Keytruda

Fake Keytruda is now advertised openly on Instagram and Facebook. Sellers create pages offering pembrolizumab at dramatically reduced prices, targeting patients and families searching online for a drug they cannot find at any licensed pharmacy. According to GeneOnline’s 2025 investigation, counterfeiters specifically target oncology medications through social media because of the broad reach and easy access to vulnerable patients.

The U.S. Food and Drug Administration issued a formal consumer warning in January 2026 about social media platforms including Instagram being used to sell fake cancer treatments. The FDA’s guidance states that any seller who does not require a valid prescription for a prescription medicine should be treated as suspicious. Pakistani patients should apply that standard to every seller they encounter online.

Red flags to watch for on social media drug sellers include:

• Prices dramatically below the legitimate Rs 200,000 to Rs 550,000 range
• No requirement for a prescription before purchase
• Promises of fast or discreet delivery with no documentation
• Accounts with little history, few followers, or recently created pages

Documented Cases: Criminals Caught With Fake Pembrolizumab

In March 2026, the U.S. Department of Justice sentenced Sanjay Kumar, a 45 year old Indian national, to 43 months in federal prison for selling counterfeit Keytruda to cancer patients through online marketplaces. During court proceedings Kumar admitted the substance in his fake vials would do nothing to treat cancer and described it as just like water. As reported by IBTimes UK, federal prosecutors called the conspiracy a direct assault on the hope of vulnerable patients.

In an earlier case documented by Medscape, two Ukrainian nationals pleaded guilty to smuggling fake pembrolizumab into the United States. They sold two boxes of counterfeit 50mg Keytruda, worth over $30,000 at legitimate pharmacy prices, to undercover agents for just $3,400. Laboratory testing confirmed those vials contained no active anticancer ingredients whatsoever.

DRAP Raids and Seizures Across Pakistan

In January 2025, DRAP exposed a large scale operation distributing fake medicines under international brand names, including products falsely labelled with pharmaceutical company addresses in France and Germany. As ProPakistani reported, DRAP issued a formal recall alert and directed the Punjab government to enhance surveillance and remove the counterfeit drugs through its full regulatory field force.

In November 2024, DRAP directed all provincial governments to crack down on unauthorised medicines after illegal imported drugs were discovered being administered inside Pakistani hospitals. Healthcare advocates have called for capital punishment for those proven guilty of producing and distributing fake cancer medicines, citing direct and fatal consequences for patients.

Key actions DRAP has taken against counterfeit cancer drugs include:

• Raids across Punjab uncovering factories using fake European pharmaceutical branding
• Recall orders issued for identified fake drug batches in January 2025
• Directives to all provincial governments to intensify surveillance in late 2024
• Instructions to the Punjab Drug Control Directorate to investigate and remove fake medicines from Lahore and surrounding markets
• Bans placed on two specific counterfeit drug batches found in active distribution

Smuggled Keytruda From Afghanistan and Across the Border

Pakistan’s long border with Afghanistan is a primary entry route for smuggled pharmaceutical products including cancer medicines. Drugs crossing through this route carry no registration, no quality testing, and no documented manufacturing origin. Keytruda must be stored at 2 to 8 degrees Celsius throughout its entire supply chain, and a vial transported across hundreds of kilometres without refrigeration has almost certainly been rendered ineffective before it arrives.

Patients who import pembrolizumab from neighbouring countries to bypass the cabinet notification delay face multiple compounding risks. The drug may be a deliberate counterfeit, an expired batch with relabelled packaging, or a genuine drug destroyed by improper storage during transport. Healthcare experts in Pakistan are clear that restoring the authorised supply chain is the only sustainable solution to this problem.

How to Spot Fake Keytruda Before It Is Administered

Every patient receiving Keytruda in Pakistan should complete these verification steps before every new batch of medication is opened. A few minutes of checking can prevent months of ineffective treatment and further cancer progression. Share these steps with your oncologist, your pharmacist, and every family member involved in sourcing the medicine.

Steps to verify a Keytruda vial before infusion:

• Inspect the solution. Genuine Keytruda 100mg is completely clear and colourless to slightly yellow with zero visible particles. Any cloudiness or floating matter means stop and verify immediately.
• Check the fill volume. A genuine 100mg vial holds 4ml of solution. A visibly underfilled vial should be flagged before the infusion begins.
• Cross check the batch number printed on the vial directly with Merck Pakistan or Merck’s global product verification system before the vial is opened.
• Confirm the purchase price. Genuine Keytruda in Pakistan costs Rs 200,000 to Rs 550,000 per vial. Any price significantly below this range requires immediate verification.
• Report any Instagram, Facebook, or WhatsApp account selling Keytruda to DRAP at dra.gov.pk and to the social media platform directly.

Roswell Park Comprehensive Cancer Center’s 2025 patient advisory confirms that Keytruda is among the most frequently counterfeited intravenous cancer therapies globally. Their clinical advice is direct: when a patient’s cancer shows no response to Keytruda treatment, one of the first questions should be whether the medicine came from a verified and authorised source.

What Needs to Change in Pakistan’s Cancer Drug System

The federal cabinet must issue the formal notification for pembrolizumab pricing that DRAP has already approved. That one step unlocks legal importation and restores the authorised supply chain. The regulatory work is complete. No new legislation is required and no new agency is needed.

Beyond that, Pakistan needs structural changes to protect cancer patients long term. As former Pakistan Pharmaceutical Manufacturers Association chairman Kaiser Waheed told Dawn, decisions that should take days currently take up to two years to clear the ministry. Cancer patients cannot wait two years.

The structural reforms Pakistan’s drug control system urgently needs include:

• Full operational independence for DRAP from the Ministry of National Health Services
• A national track and trace system for pharmaceutical supply chains modelled on the FDA’s Drug Supply Chain Security Act
• Significantly larger surveillance budgets for ongoing monitoring rather than periodic raids
• Mandatory pharmacist verification requirements for all imported oncology medicines
• Stronger cross border enforcement along the Afghanistan border to stop pharmaceutical smuggling
• Removal of all Instagram and social media accounts selling unregistered cancer drugs in Pakistan

Frequently Asked Questions

What cancers does Keytruda treat?

Keytruda treats melanoma, non-small cell lung cancer, head and neck cancer, bladder cancer, breast cancer, Hodgkin lymphoma, gastric cancer, cervical cancer, and other solid tumours. It is given as an intravenous infusion every two to three weeks. For many of these cancers, pembrolizumab is the most effective systemic therapy currently available.

How much does genuine Keytruda cost in Pakistan?

Genuine Keytruda 100mg costs between Rs 200,000 and Rs 550,000 per vial in Pakistan depending on the supplier and current exchange rate. Any offer significantly below this range should be treated as a serious warning sign and verified through DRAP before purchase or administration.

Why can pharmaceutical companies not legally sell Keytruda in Pakistan?

DRAP has approved pembrolizumab pricing and endorsed it at multiple regulatory levels, but the federal cabinet has not yet issued the formal notification required for companies to legally import and market the drug. Until that notification is published, authorised commercial importation remains blocked and patients are left without a formal supply chain.

How can I tell if my Keytruda vial is fake?

Genuine Keytruda contains a completely clear, colourless to slightly yellow solution with no visible particles, held in a 4ml vial. Cloudy liquid, floating particles, or a visibly underfilled vial are immediate warning signs. Verify the DRAP registration number on the official DRAP website and cross check the batch number with Merck Pakistan before any infusion takes place.

What happens when a patient receives fake Keytruda?

Fake Keytruda contains no pembrolizumab, meaning the patient receives zero immunotherapy benefit while their cancer continues to grow. By the time clinical failure is detected, the disease has typically progressed to a more advanced and harder to treat stage. Some counterfeit vials also contain unknown substances that cause direct physical harm beyond the treatment failure itself.

What action has DRAP taken against fake cancer drugs?

DRAP conducted raids across Punjab in late 2024 and January 2025 that uncovered counterfeit drug operations using fake European pharmaceutical branding. Recall orders were issued, provincial governments were directed to intensify surveillance, and the regulatory field force was instructed to remove identified fake medicines from circulation. Healthcare experts and the Pakistan Medical Association have urged DRAP to be granted full independence and greater resources for ongoing surveillance rather than reactive periodic raids.

The Bottom Line: Fake Keytruda and Pakistan’s Cancer Drug Crisis

A single unissued federal cabinet notification has blocked legal access to pembrolizumab in Pakistan. It has handed criminal networks the opportunity to fill that gap with fake vials sold through grey markets, Afghan border smuggling routes, and Instagram sellers.

Cancer patients who received these counterfeits lost months of treatment time while their diseases advanced. The regulatory approval is done. The human cost of not acting on it is documented and growing every week.

Verify every Keytruda vial before infusion. Confirm batch numbers with Merck Pakistan without delay. Every cancer patient in Pakistan deserves access to real medicine, and every safeguard available right now is worth taking.
