Take this medication by mouth as directed by your doctor, usually as needed. Take vardenafil, with or without food, about 1 hour before sexual activity. Do not take more than once daily. Doses should be taken at least 24 hours apart. The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Avoid eating grapefruit or drinking grapefruit juice while using this medication unless your doctor or pharmacist says you may do so safely. Grapefruit can increase the chance of side effects with this medicine. Ask your doctor or pharmacist for more details.
Mechanism of action:
Levitra typically starts working within 30 to 60 minutes after ingestion, but it may vary from person to person. Its effects can last for about 4 to 5 hours. It’s important to note that sexual stimulation is necessary for the medication to work.
Common side effects of Levitra may include headache, dizziness, flushing, stuffy or runny nose, indigestion, and back pain. In rare cases, serious side effects such as sudden vision loss or changes, prolonged erections (priapism), or allergic reactions can occur. Seek medical attention if any concerning side effects arise.
