It is free to visit an NHS doctor both in a local surgery and in a hospital. Some people choose to pay for private treatment so that they get treated faster. Dentists often charge for treatment but it is much cheaper if they are NHS dentists and you may be able to get help with these costs.
If you are aged 16 or 17 and supported by a local authority because you recently left care, you are entitled to full help with health costs through the NHS Low Income Scheme. This includes things like dentists, money for glasses and travel to medical appointments. Ask your social worker for an HC1 (SC) claim form or he end of the planner.
If your GP prescribes medication you should take the prescription to any pharmacy to get the medicine. You will not have to pay as prescriptions in Wales are free for everyone.
