Tildiem LA contains a medicine called diltiazem hydrochloride. This belongs to a group of medicines called
‘calcium-channel blockers’.
It works by making your blood vessels wider. This helps to lower your blood pressure. It also makes it easier for
your heart to pump blood around the body. This helps to prevent the chest pain caused by angina.
Tildiem LA is used for:
• High blood pressure
• Angina (chest pain)
Do not take this medicine and tell your doctor if:
• You are allergic (hypersensitive) to diltiazem hydrochloride or any of the other ingredients of Tildiem LA (listed
in Section 6 below)
Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your lips, face, throat
or tongue

below: ‘Taking other medicines’)

breath and have swollen ankles
