Re: Water retention

Hi Jan and thanks for the response.

I think the culprit might be Verapamil which I'm taking to control cluster headaches caused by a sporting head injury some years ago. Of course the information leaflet supplied with the tablets did not mention water retention as a possible side effect but the timings do coincide.

I'd just like to thank you for running this web site which is a great resource for information in plain english on my condition. Knowing about it and how to deal with it makes such a big difference.

Re: Water retention

I'll bet you're right about the Verapamil. This is a list of side effects from Mayo's information page:

Verapamil Oral

I have a brain injury from encephalitis a car accident and the best thing I have found for the headaches is low dose Benadryl (children's dose of 5 ml every 4-6 hours) and an amino acid called L-Histidine which helps with inflammation. Taking a lower dose of Benadryl keeps you from getting sleepy.

I'm glad the site is helpful!
