These Medications Can Affect How Viagra Works
Your doctor needs to know about all medications you are taking, both prescription and over the counter, as well as any vitamins or herbal supplements. They may affect or be affected by taking Viagra. Always know what medications or supplements you are taking. Keep a list of them in your wallet so it is available when you need it. Never stop or start a medication without checking with your doctor.
Tell your doctor or pharmacist of you take any of the following:
- Any alpha blockers.
- Medication to treat an abnormal heartbeat. These include procainamide, quinidine, amiodarone and sotalol.

Possible Viagra Side Effects
All medications you talk flow throughout your body and may cause unintended side effects. This is also true for Viagra. These are some possible side effects to watch for:
- Viagra blocks PDE5, but can also block PDE6 which is used in the cone cells of your retina, causing the way you perceive green and blue to be affected. Or you may see the world with a bluish tinge for several hours.
- You may experience a heart attack. Because of this possibility, Viagra is only dispensed as a prescription drug.
Be sure your doctor knows your medical history.
- You may have a problem with taking Viagra if you also take Nitroglycerin. That drug increases nitric acid production to help with angina pain by opening up the arteries which supply your heart with oxygen.
- You may experience a headache. Viagra causes the arteries in your brain lining to be opened up which causes excess pressure.
- You may experience a prolonged erection which could cause lasting damage to your penis. You may also have problems with future erections. If your erection lasts longer than four hours, seek medical help.
- If Viagra is taken when it isn't needed you could develop a dependence on it and not be able to maintain an erection without it.
Do not give your Viagra to anyone else even if they have the same symptoms. Taking Viagra can result in some serious side effects, even death. A medical professional must evaluate each patient individually to determine if it is appropriate to take Viagra.
If too much Viagra has been taken, it may result in nausea, dizziness, or discomfort, tightness, numbness or tingling in the chest, arms, jaw or neck during sexual activity. If you experience any of these symptoms, immediately stop sexual activity and call your doctor or go to the emergency room.
