Viagra and Headaches
Viagra (sildenafil) is a prescription medicine used for treatment of erectile dysfunction. It belongs to a class of medications called PDE5 inhibitors, others being tadalafil (Cialis) and vardenafil (Levitra). These medications work by dilating the blood vessels to the penis resulting in an erection.
Like other medications, Viagra can cause some side effects and headache is among the most common. Many men taking Viagra report headaches especially during the start of treatment.
What Studies Say?
Before a medication gets approved for distribution, it is carefully evaluated through placebo-controlled clinical trials. These studies are participated by thousands of people. Data about the medication are then gathered and compared with another group of participants who took “dummy pill” or placebo. Side effects are then noted and classified either as “common side effect” (those reported by more than 1 percent of users) or “rare side effects” (those reported by less than 1 percent of users).
During clinical trials, headache was reported by about 16% of men who were given Viagra. It tops the list of “common side effects”. Compared to other ED medications, headache was more commonly reported by people taking Viagra. It is not entirely clear how Viagra causes headaches. However, it is suggested that the dilation of blood vessels is not just limited to the penile region but also affects the entire body including the brain. The increased blood flow to the brain can probably lead to headaches.
Individuals may experience mild to severe headache. It is also thought that headache is dose dependent, meaning men taking higher doses of the medication have increased chances of suffering from headache.
Managing A Headache Caused by Viagra
Although not all men experience headaches while on Viagra, it is best to know how you can manage this side effect in case it occurs.
A Viagra-induced headache often resolves by itself without medical intervention. However, for some people, this side effect can become disturbing and prolonged. If you experience severe headaches while on Viagra, your healthcare provider may recommend reducing your dosage. Work with your physician closely to get the lowest effective dose of Viagra for you.
Your healthcare provider may also prescribe over-the-counter pain medication such as Aleve or Tylenol. Depending on the severity of headache, you may take pain reliever every four to six hours. Be sure to take the pain reliever exactly as instructed by your healthcare provider. Do not take more than the recommended amount.
Some people are sensitive to the effects of Viagra and develop headache if it is taken on an empty stomach. If this is the problem, you can try taking it with meals or light snack. Others experience moderate to severe headache if they drink alcohol while taking Viagra. Therefore, you should avoid drinking alcohol, especially in large amounts using this medication.
Be sure to consult your physician if you continue to experience headaches even after dose adjustments or use of pain relievers. Your healthcare provider may consider prescribing other medications or treatment alternatives.
