Viagra is generically known as sildenafil tablets. Some girls will not be affected if they mistakenly take it, but others will experience flushing and palpitations. Sildenafil tablets are clinically used to treat erectile dysfunction in men and should not be taken by girls. Some girls may not experience any abnormalities after taking sildenafil tablets by mistake. Some girls may experience flushing, palpitations (rapid heartbeat, often accompanied by panic), dizziness and other symptoms after taking the drug due to different dosages of the medication and physical condition. If the girls themselves are allergic to sildenafil tablets, they will have allergic reactions after taking the drug by mistake, such as itching of the skin, breathing difficulties, etc., which may be life-threatening if treatment measures are not taken in time. Meanwhile, if the girls themselves take nitrates, the accidental intake of sildenafil tablets may lead to a further drop in blood pressure. When girls take sildenafil tablets by mistake, they can reduce the effects of the drug on the organism by inducing vomiting, etc., and seek medical attention if necessary. The drug should be applied under the guidance of a doctor.
