acciclovir too much ?

[Johnd]

Hello. every time i think i am getting an outbreak i take episodic medication (3 times a day for 5 days 400 mg acyclovir) in the past 3 weeks i took it twice and yesterday i started again., i am leaving on a trip so i guess i am nervous. i am now on the 2nd day and this morning about an hour of taking a pill i had redness on my chin and maybe my bottom lip was a little swollen. the redness went away after an hour. could it be an allergic reaction from too much medication? i am scared now. btw i took it so much these last few weeks because i don't want an outbreak before or during the trip.now i don't know if to just stop taking the episodic treatment i started yesterday because maybe my body is allergic now or it was too much and if i do stop in the middle will it trigger an outbreak?

Thanks.
