What you have to remember is that the tablets are anti fungal not antibiotics which are anti bacteria.
The side effects are not much different from an antibiotic such as fluoxacillin.
If they were that nasty they wouldnt be produced in the first place would they? Sporanex pulse is taken for, iirc, 3 weeks then one week off then another 3 weeks on cycle.
I have noticed that patients who are retired GP's seem to find it quite easy to get prescribed anti fungal tablets whereas retired people their age dont. Strange that.
If you have a nail removed and destroyed at the root using phenol (carbolic acid) then it will not grow back, if you dont destroy them they grow back deformed due to the trauma of the op. It's not a rough operation but the action of surgically removing it damages the cells that grow the nail forever.
You have to remember the GP's have a budget and see lamisil and the like as expensive.
Always question what health professionals tell you (even podiatrists) as patients do get lied to, usually to deflect them away from the cold hard truth that they cannot have xyz due to cost.
Tea tree is useless for fungal nails ime but some patients tell me it worked for them, it works in the petri dish if you drop it on the fungas neat but when it's growing in the nail keratin it seems to offer some natural protection to the turpinols in the oil. And it stinks when your treating the feet. That and Dettoll (wtaf?) are the two most common things I smell on patients feet.
