Fildena CT 100 mg is typically taken 30 to 60 minutes before sexual activity. Its effects can last up to 4 to 6 hours, but sexual arousal is necessary for it to work. It should not be taken more than once a day. Common side effects may include headache, flushing, nasal congestion, dizziness, and indigestion. Men with heart problems or those taking nitrates should not use this medication due to the risk of a serious drop in blood pressure.
