Overdosage
There is limited experience of overdose with saquinavir.
No acute toxicities or sequelae were noted in 1 subject who ingested 8 grams of INVIRASE as a single dose. The subject was treated with induction of emesis within 2 to 4 hours after ingestion. A second subject ingested 2.4 grams of INVIRASE in combination with 600 mg of ritonavir and experienced pain in the throat that lasted for 6 hours and then resolved. In an exploratory Phase II study of oral dosing with INVIRASE at 7200 mg per day (1200 mg q4h), there were no serious toxicities reported through the first 25 weeks of treatment.
Treatment of overdose with saquinavir should consist of general supportive measures including monitoring of vital signs and ECG and observations of the patient's clinical status. Since saquinavir is highly protein bound, dialysis is unlikely to be beneficial in significant removal of the active substance.[1]
