A retired soldier who served in Chad and Liberia is suing the State claiming he suffered personal injuries as a result of being prescribed the anti-malaria drug Lariam.
Anthony Moore, a member of the Defence Forces for 25 years, has brought his action in the High Court.
Mr Moore of Drimnagh, Dublin has claimed he suffered and continues to suffer serious personal injuries, loss and damage following the use of Lariam.
It is claimed he first began to experience problems while posted to Liberia when he noticed a swelling in his hands which he initially ascribed to working in a humid and hot environment.
He has alleged that after first taking the drug he had hallucinations and disturbing dreams. He also claimed he suffered severe pain in his shoulders and back, causing lack of sleep, and this continued after he returned from his tour of duty.
It is claimed it was the duty of the State to provide a safe place and system of work, and to ensure all medicines prescribed would be safe to use. The claims are denied.
