Dihydrocodeine tartrate (DF 118 Forte / DHC Continus) is an opioid drug that is used as a painkiller. It is used to relieve moderate to severe pain, particularly after surgery. It is usually taken by mouth. Dihydrocodeine can also reduce coughing.

Co-formulations of dihydrocodeine and paracetamol are available, since these two drugs enhance each other’s painkilling properties. This combination is called co-dryamol.

Side-effects of dihydrocodeine include giddiness, feelings of hyperactivity, headaches and difficulty breathing. Dihydrocodeine can also be abused, leading to dependence and addiction in rare cases.

Dihydrocodeine is not known to interact with any anti-HIV drugs.
