DDAVP

If nasal congestion, scars, or swelling inside the nose make it difficult to absorb DDAVP, your doctor may temporarily stop the drug or give you tablets or an injectable form. If you are switched to tablets, you should start taking them 12 hours after you last used the nasal spray or nose drops.

• If you miss a dose...
  Take the forgotten dose as soon as you remember. If you take 1 dose a day and don't remember until the next day, skip the dose. If you take DDAVP more than once a day and it is almost time for the next dose, skip the one you missed and go back to your regular schedule. Never try to "catch up" by doubling the dose.

• Storage instructions...
  The drops should be stored in the refrigerator. If you are traveling, they will stay fresh at room temperature for up to 3 weeks.

The tablets and nasal spray can be kept at room temperature. Protect the tablets from heat and light.
