Formed in 1993, IHD is a finished goods logistics service provider to a number of multinational pharmaceutical manufacturers. IHD currently distributes for Abbott Laboratories, Bayer Healthcare, Boehringer Ingelheim, Bristol-Myers Squibb, EAS, Eli Lilly, Genop Healthcare, MSD, Novartis, Nutrimax, Pfizer, Pharmaco, Roche, Schering, Schering-Plough, Wyeth South Africa and companies in the sanofi-aventis group.

The company operates nationally from five distribution centres within South Africa (Linbro Park, Bloemfontein, Cape Town, Port Elizabeth and Durban), and employs nearly 500 people around the country.

IHD does not take ownership of the product, nor play any role in the marketing activities or pricing decisions of these products. This remains the responsibility of the manufacturer concerned. The company receives orders, processes these through the picking and packing procedure, invoices orders, delivers the product and manages the debtors book on behalf of the manufacturers. IHD supplies to any person or entity permitted to purchase pharmaceuticals for on-sale or dispensing purposes, and does not supply directly to members of the public.
