What is this medicine used for?Treatment of erectile dysfunction in males. Tri-Mix contains three drugs mixed in a sterile injection. They are:
1.) Papaverine:A drug that causes blood vessels to expand (vasodilator): it produces an erection by increasing blood flow to the penis.
2.) Phentolamine:When injected into the penis, it produces an erection by increasing blood flow to the penis.
3.) Prostaglandin E-1:A potent hormone-like substance that can control blood pressure, helping produce erections.
Reasons not to take this medicine:Do not take this medicine with any of the following medications: hypersensitivity or allergy to any component of this formulation; conditions predisposing you to priapism (painful erection lasting 4 hours or more): sickle cell anemia, multiple myeloma or leukemia; anatomical deformation of the penis or with penile implants; direction by your physician that sexual activity is inadvisable or contraindicated.
Key warnings before taking this medicine?Tell your doctor if you have a condition or are taking a medicine that interferes with blood clotting.
What are the precautions when taking this medicine?Give your health care provider a list of all the medicines, herbs, non-prescription drugs, or dietary supplements you use. Some items may interact with your medicine.
How is it best taken?Ideally, the injection should be administered just prior to foreplay. To prevent bruising, apply firm pressure to the injection site for 5 minutes after injection. It is administered via intra-cavernosal injections and should produce an erection in 5 to 20 minutes and can be expected to last up to one hour. Do not use Tri-Mix Injection more than 2 times a week; use at least 24 hours apart. There is a possibility of needle breakage with use of Tri-Mix Injection: you should pay careful attention to your doctor's instructions and handle syringe and needle properly. If the needle breaks during injection, you should promptly contact your doctor.
What do I do if I miss a dose?Do not take double or extra doses. This medicine should only be taken 5 to 20 minutes before intercourse.
What are some possible side effects of this medicine?Mild to moderate pain during injection; painful sensation with erection; small amount of bleeding at the injection site. Call your healthcare provider if you notice any redness, lumps, swelling, tenderness or curvature of the erect penis. If you experience an erection lasting more than 2 hours, you may take 2 - 4 pseudoephedrine 30 mg by mouth once and apply an ice pack. If your erection does not go away within the next hour, seek professional help immediately. Erections that last more than 6 hours can cause serious damage to penile tissue.
How should I store this medicine?The mixture is not stable for long periods. Our studies indicate that frozen preparations are stable for a year. Otherwise keep this medicine in a refrigerator below 41°F (5°C).
