Headaches are a common side effect reported by some individuals who take medications containing sildenafil citrate, such as Fildena 100. There are several reasons why someone might experience headaches after taking Fildena 100:
- Vasodilation: Sildenafil citrate works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), leading to vasodilation (widening of blood vessels). While this increased blood flow to certain areas of the body, such as the penis, is desired for the treatment of erectile dysfunction, it can also lead to vasodilation in other areas, including the head, which may result in headaches for some individuals.
- Blood pressure changes: Sildenafil citrate can cause slight decreases in blood pressure, particularly when taken with other medications that also lower blood pressure or with alcohol. Changes in blood pressure can sometimes lead to headaches.
- Dehydration: Sildenafil citrate may increase fluid loss through increased urination, particularly if accompanied by alcohol consumption. Dehydration can contribute to headaches in some individuals.
- Individual sensitivity: Some people may simply be more sensitive to the effects of sildenafil citrate and may experience headaches as a side effect even at lower doses.
- Interaction with other medications: If someone is taking other medications that interact with sildenafil citrate, such as certain antibiotics or antifungal medications, it could increase the likelihood of experiencing headaches as a side effect.
