This medicine is given by injection (shots) directly into the penis to cause an erection in adult males who have problems with erections. It may also be used to help diagnose such problems. This medicine may also be used for other conditions as determined by your health care provider.
The correct amount of medicine you need to cause an erection is usually determined by your health care provider in the office or clinic. Thereafter, you will self-inject this medicine following your health care provider's instructions and the instructions included in the medicine package.
These shots are different from other types of shots. Carefully follow the instructions in the medicine package to prepare the medicine for injection. Ask your health care provider or pharmacist about anything you do not understand.
