I stayed in The Gambia for several weeks in the rainy season and was quite reluctant to take traditional preventative medicine due to the side effects. Demal 200 was easy to take and carry around, did not have any nasty side effects and I stayed malaria free. My friend took the traditional preventative medicine and was quite ill with dizzy spells. It is thought this is down to her tablets. This has continued for 6 months. I will definately use Demal 200 next time I am in a malaria risk country. I have even had it sent to someone in Africa who had malaria. They are fine now and appear malaria free.
