Lariam (Mefloquine) Compensation Claims | Irwin Mitchell Solicitors

Our expert military injury lawyers will provide you with free initial advice on your compensation claim and with our No Win No Fee agreements there's no financial risk to you if you're unsuccessful*.

Soldiers that are deployed overseas may be given Lariam (also known as Mefloquine) tablets to prevent malaria, despite the drug’s long list of potential psychological side effects being well known. These symptoms include:

  • Psychosis
  • Suicidal thoughts
  • Self-endangering behaviour 
  • Severe anxiety
  • Paranoia
  • Hallucinations 
  • Depression 
  • Panic attacks
  • Personality changes
  • Aggression

If you were prescribed Lariam without being warned of its dangers, and have since suffered psychiatric problems, our military solicitors could help you claim compensation for any side effects you've suffered. We've worked for many years to help members of the armed forces and are currently acting for several soldiers who've suffered from side effects of Lariam from different military backgrounds.

What’s The Process For Making A Lariam Compensation Claim?

We’ll take a detailed look at your medical records, investigating:

  • How Lariam was prescribed to you (whether individually or as a group)
  • The extent to which you were warned about Lariam’s adverse effects
  • The type of symptoms you experienced, when they started to happen and how they developed
  • The treatment you received

Once we’ve gathered this evidence we’ll need to establish a link between your injuries and the misprescription of Lariam. We’re aware of the fact that mental health issues are rarely discussed in the military, and will always handle your case sensitively. 

The Ministry of Defence (MoD) didn’t offer any alternative anti-malarial drugs to most personnel who suffered negative side effects after taking Lariam. As Lariam is a prescription-only drug, this means the same principles that apply in civilian prescriptions also apply to the military. The availability of other anti-malaria treatments tells us that other options should have been offered to soldiers who were at risk of harmful psychiatric symptoms.

Prescription should take place on a one-to-one basis, with the prescriber taking a detailed medical history and asking questions to determine whether Lariam is a suitable drug for you. The additional pressures – psychological and physical – of a military environment should also be taken into account when prescribing drugs.

Why Make A Claim?

Safer alternatives to Lariam have been widely available since 2007, making the MoD’s lack of action seriously concerning. Many other countries’ militaries have either banned it or ruled it a “drug of last resort”, including:

  • America
  • Canada
  • Denmark
  • France
  • Germany
  • The Netherlands

If you’ve been prescribed Lariam since 2004 and have suffered negative psychological symptoms (either on deployment or post-deployment), we may be able to help you to claim.

In many cases you won’t have been warned of Lariam’s potential for harmful effects, with the anti-malarial drug simply being prescribed en masse.

The continued use of Lariam in the British military is incredibly worrying, given the potential severity of its side effects. We believe any personnel that have been affected by Lariam deserve to know how and why the drug is still prevalent in the Armed Forces.

Are There Any Time Limits For Claiming Compensation?

You have three years to make a claim, starting from the date of your injury or the date that you became aware that it had been caused by Lariam and the way it was prescribed. 

However, it’s important to contact a solicitor as soon as possible so that we can begin to investigate your claim, contact witnesses and gather evidence.
