If you get a prescription for Malarone, then Tesco's is just over £2 per tablet.
Side Effects - Adverse reactions to mefloquine, as to other antimalarials, have been recognised for many years. Recent concern has focused mainly on neuropsychiatric reactions. This term is used to cover one main neurological phenomenon (convulsions) and several psychiatric disorders including insomnia, vivid and unpleasant dreams, agitation, anxiety, irritability, depression, feelings of unreality, panic attacks, hallucinations, and frankly psychotic episodes.
Of course you may easily avoid these side-effects if you buy tablets in country. They may easily turn out to be re-labelled aspirin. Or simply don't bother with the tablets. You get malaria instead. Death may occur from general debility, anemia, or clogging of the vessels of cerebral tissues by affected red blood cells. Cerebral malaria is most commonly seen in infants, pregnant women, and nonimmune travelers to endemic areas.
