Can this guide tell me whether IV therapy is suitable for me?

No. Suitability depends on an individual clinical assessment, your history, current medicines and the proposed treatment.

Should I stop my prescribed medication before treatment?

No. Do not change prescribed medicines unless the clinician managing them tells you to do so.

What should I bring to my appointment?

Bring a medication and allergy list, relevant medical information and any recent results requested by the clinic.

What if I feel unwell after treatment?

Follow the aftercare instructions you received. Use 999 for life-threatening symptoms and NHS 111 for urgent non-emergency advice when you are unsure.

IV Therapy Preparation, Side Effects and Aftercare

What to discuss before treatment, how to recognise a concern and why clinician-led suitability assessment matters.

Before your appointment· Bring a full medication and allergy list, details of kidney, heart or other long-term conditions, and recent test results. Do not conceal symptoms such as fever, chest pain, breathlessness or a new rash.

IV therapy is not suitable for everyone and should be considered only after an individual clinical assessment. Before treatment, tell the clinician about your medicines, allergies, medical conditions and current symptoms; after treatment, follow the specific aftercare advice you receive and seek urgent help for severe or rapidly worsening symptoms.

I approach IV therapy as a clinical intervention rather than a general wellness shortcut. Any discussion should cover the reason for considering it, realistic evidence limits, alternatives, relevant blood results where appropriate and the specific product or treatment pathway offered by the clinic.

No online guide can determine whether IV therapy is safe or appropriate for you. Suitability, benefits and risks depend on your health history, the intended treatment and the clinician's assessment.

Preparation and suitability assessment

The clinician should review your reason for attending, relevant history, current medicines, allergies and any recent results. Ask what is being proposed, what evidence supports it for your circumstance, the alternatives and what follow-up is planned.

Do not assume that a product is suitable because it is available elsewhere or because it is described as a wellness treatment.

Possible side effects and aftercare

Possible concerns vary with the treatment and person. A clinician should explain expected short-term effects, symptoms that need a call to the clinic and symptoms that need urgent NHS care before treatment begins.

Follow the clinic's individual aftercare instructions. Do not start, stop or change prescribed medicines on the basis of a wellness treatment or an online guide without medical advice.

Seek urgent help rather than waiting for routine follow-up if you develop severe or rapidly worsening symptoms.

Urgent symptoms

Call 999 for severe breathing difficulty, swelling of the face or throat, severe chest pain, collapse, confusion, seizure, signs of stroke or another life-threatening emergency. Use NHS 111 for urgent non-emergency advice when you are unsure. Contact the treating clinic for the specific non-urgent aftercare route you were given.
