Drug Name
Apcalis SX

Drug Uses
Apcalis SX is a jelly solution for the treatment of male erectile dysfunction, often called impotence.

How to use
For most patients, Apcalis SX should be taken once a day as needed. In patients taking certain protease inhibitors (such as for the treatment of HIV), it is recommended to not exceed a maximum single dose of 25 mg of Apcalis SX in a 48-hour period.

Drug Class and Mechanism
Apcalis SX increases blood flow to the penis allowing more blood flow into the penis like happened naturally when a man is sexually stimulated. With more blood flowing in and less flowing out, the arteries in the penis enlarge resulting erection.

Missed Dose
If you miss a dose of this medicine, take it as soon as possible. Do not take 2 doses at once.

Storage
Apcalis SX should be stored at room temperature, 15-30 degrees C (59-86 degrees F).

Warnings/Precautions
Before you start any treatment with Apcalis SX, be sure to ask your healthcare provider if your heart is healthy enough.

If you're a man who uses nitrate drugs, like nitroglycerine, never take Apcalis SX. The combination of Apcalis SX and nitrates can make your blood pressure suddenly drop to unsafe levels. You could get dizzy, faint, or even have a heart attack or stroke. Nitrates are found in many prescription medications that are used to treat angina (chest pain due to heart disease).

If you are not sure, whether any of your medications contain nitrates, or if you do not understand what nitrates are, ask your healthcare provider or pharmacist.
