My son began this for a trip to Indonesia and shouldn't have been prescribed it due to prior anxiety issues that he didn't think were severe enough to mention. He is having bad symptoms on it... will have to come home as it's that bad and may be home in time to not take the next dose and change drugs for the post trip time, but until then is there anything one can take to ease the anxiety/paranoia while experiencing it? Getting medical help abroad is not as easy as here. If he did have to stay on and was able to get another anti-malarial drug, how does one switch over and when would he notice the adverse symptoms easing? Thanks.
