Hi Paul,
Thank you for taking the time to review your treatment; I am very sorry to hear that you have had this experience with the Aciclovir 400mg Tablets.
As a regulated UK pharmacy, we take reports of this nature seriously and we appreciate you bringing this to our attention. We immediately escalated your feedback to our clinical team for further guidance and we have been in regular communication with you.
Our clinical lead has confirmed that there are no listed cardiac side-effects listed within the product literature for this treatment. Therefore, we strongly recommend that you seek medical attention to investigate the underlying cause of suspected atrial fibrillation (arrhythmia).
The most effective way to diagnose an arrhythmia is with an electrical recording of your heart rhythm called an electrocardiogram (ECG). It is sensible to discontinue the treatment supplied until you have had a full face-to-face assessment with a health professional to discuss this incident further.
Where possible we do provide the item pictured on our website and underneath the image for this treatment, we advise customers to contact us directly, if a specific brand is required.
Please be reassured that all brands of this treatment are made to British Pharmacopeia (BPC) standards regarding the core ingredient, only the inactive ingredients may vary. We use the same suppliers as the main high-street pharmacy chains and all the medication dispatched is brand new.
We are glad to hear that you are now feeling better and our clinical team remains available to you.
