Cialis and Viagra are both FDA-approved medications used to treat erectile dysfunction. While they work in similar ways, each drug has a different chemical composition and differs in price, dosage, how quickly it works, and how long it lasts.
Viagra is a blue pill available in 25mg, 50mg, and 100 mg tablets. Cialis is an orange pill available in 2.5mg, 5mg, 10mg, 20mg, and 40mg doses. Both drugs take approximately 30 minutes to become effective. Viagra lasts about 4 hours. Cialis is available as a once-daily pill or as a high dose tablet that can last for up to 36 hours. The price will depend on various factors, including quantity and dosage.
Your doctor will consider your medical history, how each medication works, and other factors when deciding which medication is a good choice for you. Only take medications to treat erectile dysfunction as directed by a US licensed physician.
