More Info


Viagra, known generically as sildenafil, is a medication primarily used to treat erectile dysfunction. It works by increasing blood flow to the penis, helping to achieve and maintain an erection. When it comes to drug testing, particularly in military or workplace settings, the concern often revolves around whether certain medications will yield a positive result for illicit substances.

To address your question directly: Viagra is not classified as a controlled substance, and it is not typically included in standard drug tests. Therefore, if you take Viagra tonight, it should not cause a positive result in a urine drug test conducted the following day. Standard drug tests usually screen for substances such as marijuana, cocaine, opiates, amphetamines, and benzodiazepines, among others. Sildenafil does not fall into any of these categories.

However, it is important to note that while Viagra itself will not cause a positive drug test, there are a few considerations to keep in mind:
1. Drug Testing Variability: Different organizations may have different protocols for drug testing. Some may conduct more extensive tests that could include a wider array of substances, but Viagra is still not commonly included.

2. False Positives: While Viagra is unlikely to cause a false positive for illicit drugs, there are instances where certain medications can lead to unexpected results. If you are taking other medications or supplements, it is wise to inform the testing administrator.

3. Medical Disclosure: If you are in a military setting or a workplace with strict drug policies, it may be prudent to disclose any medications you are taking, including Viagra. This can help avoid any potential misunderstandings during the testing process.

4. Health Considerations: If you are prescribed Viagra, it is usually for a legitimate medical reason. It is essential to follow your healthcare provider’s instructions regarding its use. If you have concerns about how it may affect your health or any drug testing, discussing these with your doctor is advisable.

5. Potential Interactions: If you are taking other medications, especially those that might affect blood pressure or heart function, it’s crucial to consider potential interactions. Always consult with your healthcare provider about all medications you are taking to ensure safety and efficacy.

In summary, taking Viagra should not result in a positive drug test for illicit substances. However, always stay informed about the medications you are using and maintain open communication with your healthcare provider and any relevant authorities regarding your health and medication use. If you have further questions or concerns about drug testing protocols or the implications of taking Viagra, consider reaching out to a medical professional or the testing organization for clarification.
