What happens if I miss a dose of p-aminosalicylic acid?

If you miss a dose of p-aminosalicylic acid, take the medication as soon as possible, unless it is almost time for the next scheduled dose. If it's almost time for your next dose of  p-aminosalicylic acid, skip the missed dose and return to your regular schedule. Never take two doses of  p-aminosalicylic acid at once. If you overdose, contact poison control or call an ambulance.
