What happens if I miss a dose (Aralen Phosphate)?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose (Aralen Phosphate)?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of chloroquine can be fatal, especially in children.
Treatment of a chloroquine overdose must be started quickly. You may be told to induce vomiting right away (at home, before transport to an emergency room). Ask the poison control center how to induce vomiting in the case of an overdose.
Overdose symptoms may include headache, drowsiness, nausea, vomiting, vision changes, seizure (convulsions), slow heart rate, weak pulse, fainting, slow breathing (breathing may stop).
What should I avoid while taking chloroquine (Aralen Phosphate)?
Avoid taking an antacid or Kaopectate (kaolin-pectin) within 4 hours before or after you take chloroquine. Some antacids can make it harder for your body to absorb chloroquine.
If you also take an antibiotic called ampicillin (Principen, Unasyn), avoid taking it within 2 hours before or after you take chloroquine. Chloroquine can make ampicillin much less effective when taken at the same time.
This medication may cause blurred vision and may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert and able to see clearly.
