What are the precautions to be taken if I want to use viagra?
Sildenafil citrate is a prescription medication, so you'll need to talk to your health care provider to find out if it's right for you. Be sure to ask your health care provider if your heart is healthy enough to handle the extra strain of sexual activity.
If you have chest pains, dizziness, or nausea during sex, stop and immediately tell your health care provider. Remember to protect yourself and your partner from sexually transmitted diseases.
