How soon you can have intercourse after shingles depends on the severity of the shingles and the location of the shingles. If shingles is severe, you should wait half a month to a month after the rash has dried up and scabbed over before having intercourse. If the shingles is on the vulva or buttocks, it will take about half a month to a month for the shingles to completely heal or be cured before having intercourse to avoid the chance of shingles occurring in the spouse. The treatment of shingles requires oral antiviral medications such as valacyclovir hydrochloride tablets, famciclovir tablets, and acyclovir tablets. If the condition is severe, acyclovir injection or ganciclovir injection can also be administered and acyclovir ointment can be applied. If there is exudation, a 2% boric acid solution can also be applied topically twice a day.
