Sleeping after taking Viagra may result in an increased number of nighttime erections. However, Viagra itself doesn't cause sleepiness; it's primarily intended to treat erectile dysfunction. Therefore, whether or not you can sleep after taking it depends on individual factors and isn't inherently problematic.
Understanding Viagra and Sleep
Viagra, or sildenafil, is a medication designed to improve erectile function, not induce sleep. Multiple sources confirm that Viagra does not cause drowsiness. This NHS page explicitly states that it's usually safe to drive after taking sildenafil because it doesn't make you sleepy.
However, studies indicate that taking Viagra before bed can lead to more frequent nighttime erections. This is because Viagra increases blood flow, which can affect erections even during sleep. This study supports this finding, noting that sildenafil taken at bedtime significantly increases nocturnal erections in patients with erectile dysfunction.
It is crucial to remember that the effects of Viagra last for a few hours, varying based on factors like age, health condition, and dosage. As noted here, these factors should be considered.
Practical Considerations
- Intended Use: Viagra is for treating erectile dysfunction and should be taken when sexual activity is anticipated.
- Side Effects: While sleepiness isn't a common side effect, other side effects like headaches, flushing, or nasal congestion might affect sleep.
- Individual Response: How Viagra affects sleep will vary depending on individual factors.
