Online Doctor (UK)
 

There's an online doctor/GP service here:

http://www.e-med.co.uk/

for UK users. They are not cheap but offer online consultation by email, and will ship medicines etc. Register with them before you travel. I used them for a recent trip to Cambodia (ameobic dysentery) . They also do a great Medi Pack, antibiotics, syringes, needles, painkillers etc to take with you.
A good reassurance for travellers, although drugs are cheaper abroad it's good to have an online doctor - and their Medi Pak includes a lot of prescription only stuff. They have been great for me, when my GP sent me away untreated with Am. Dysentery.
