If you suffer from erectile dysfunction, you may be desperate to find a suitable treatment option that will enable you to enjoy lovemaking again. Many men are so excited about this prospect that they rush over to their doctor’s office to obtain a prescription for the small blue pills. They may even decide to take more pills than prescribed to enhance their lovemaking even further. However, this is a very unwise decision. You should never take more than the prescribed dosage of any medication, including Viagra. The drug is available in 25mg, 50mg and 100mg doses, and it is not usually recommended to exceed 100 mg a day. However, factors such as certain other medications, your age and any present medical conditions can also affect how Viagra works. That’s why it’s important to discuss your situation with your doctor. Together, you can find a suitable dosage that will work best for you without compromising your safety.
