What is Spedra and how does it work?
Spedra is a medication that contains the active ingredient avanafil, which is a phosphodiesterase type 5 inhibitor (PDE5 inhibitor). It is primarily prescribed to treat erectile dysfuction.
Spedra tablets are available in 50mg, 100mg and 200mg doses.
Avanafil causes the blood vessels in your penis to relax and improves the blood flow to the penis. As a result, you will find it easier to get and maintain an erection. Spedra will not cause an erection without sexual stimulation.
How to take Spedra
You need to take one Spedra tablet approximately half an hour before intercourse. You can take it with or without food, but taking the tablet with food means that it may take longer to work.
You must not take more than one Spedra tablet per day. Avoid drinking alcohol while taking Spedra, as it increases your risk of side effects such as dizziness, headaches and low blood pressure. Alcohol also has a negative impact on your ability to gain an erection.
Avanafil, in Spedra, interacts with grapefruit juice. You should avoid consuming grapefruit or grapefruit juice 24 hours before taking Spedra.
The standard dose of Spedra is 100mg. The dosage you will be prescribed depends on what works best for you. If you are currently taking any other medication, you may need a different dosage. Your doctor will advise you on which dosage to take when you get your prescription. It is important that you mention any medication you are currently taking, so your doctor can prescribe the most suitable dosage.
