If your NHS prescription is not being filled, it's crucial to address the issue promptly. Start by contacting your GP or the pharmacy where you submitted the prescription to understand why it's not being filled. There could be various reasons, such as stock shortages or issues with the prescription itself. If the problem persists, you may need to seek a review of your prescription or request an alternative treatment. Remember, medications are essential for your health, and you have the right to receive them without unnecessary delays.
