How to use delavirdine:
Use delavirdine as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- An extra patient leaflet is available with delavirdine. Talk to your pharmacist if you have questions about this information.

- Do NOT take antacids or didanosine within 1 hour of taking delavirdine.
- Certain strengths of delavirdine may be dissolved in water. Before doing so, make sure that your strength of delavirdine can be dissolved in water. To dissolve, add the tablets to at least 3 ounces (90 mL) of water. Allow the medicine to stand in the water for a few minutes. Stir the mixture until the tablets dissolve completely and drink it immediately. Rinse the glass with water and drink the rinse to be sure the entire dose is taken. Do not store the mixture for future use.
- Take delavirdine on a regular schedule around the clock, unless your doctor tells you otherwise.
- Continue to take delavirdine even if you feel well. Do not miss any doses.
- If you miss a dose of delavirdine, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once. If you miss several doses, contact your health care provider.
Ask your health care provider any questions you may have about how to use delavirdine.
Important safety information:
- Delavirdine may cause drowsiness or dizziness. These effects may be worse if you take it with alcohol or certain medicines. Use delavirdine with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
- Do not take more than the recommended dose, change your dose, or stop taking delavirdine without checking with your doctor. Taking more than the recommended dose of delavirdine may not provide additional benefits and may increase the risk of side effects.

- Delavirdine is not a cure for HIV infection. Patients may still get illnesses and infections associated with HIV. Remain under the care of your doctor.
