Spedra contains an active ingredient called avanafil, which belongs to a group of medicines called PDE5 inhibitor. It helps to relax the blood vessels and increases blood flow to your penis when you are sexually stimulated, allowing you to maintain erectile long enough to achieve satisfactory sexual activity.

How to take

The starting dose for Spedra is usually 100mg for ED, taken about 15-30 minutes before you plan to have sex. There might be different dose adjustments if you feel that it is too strong/weak or if you take any other medicines. Grapefruit juice should be avoided within 24 hours prior to taking Spedra. You should not take the medicine for more than once a day. It is important to note that Spedra only works if you are sexually aroused.

Side effects of Spedra

Like all medicines, Spedra can cause some side effects, although not everyone gets them.

The most common side effects associated are headache, nose congestion, facial flushing, and hot flush. Side effects are usually mild but if you are concerned about any side effects of the medicine, you should speak to your doctor of pharmacist for more advice. If you experience dizziness while using Levitra, you should avoid driving or using machinery.
