The Health Service Executive (HSE) is warning pharmacists that it will seek legal action if their dispute over fees paid for the state drugs scheme continues.
In a letter issued to pharmacists the health authority said that a pharmacy with a HSE agreement which is not providing medications under the state drugs scheme is in breach of its legal obligations.
It also said that those involved are neglecting their duty of care to their clients.
The HSE has set up temporary dispensing units, but there have been reports of patients in rural areas having major problems getting their medication.
