Cialis: Known for its longer duration of action, Cialis can last up to 36 hours in some individuals.
Filagra: Typically, the effects of Filagra last around 4-6 hours, similar to Viagra.
Common Side Effects:

Interactions and Precautions:

Both Cialis and Filagra can interact with certain medications, particularly nitrates used for chest pain (angina) and alpha-blockers used to treat high blood pressure or prostate enlargement. They should not be taken with these medications as serious interactions can occur.
Both medications may also have interactions with other drugs, so it's important to inform your healthcare provider about all medications you are taking.
Individuals with certain medical conditions such as heart disease, liver or kidney problems, low blood pressure, or a history of stroke should use these medications with caution and under medical supervision.
Overall, while Cialis and Filagra are both effective treatments for ED, they have similar common side effects due to their mechanism of action but may differ in terms of onset, duration, and less common side effects. It's essential to discuss with a healthcare provider which medication is most suitable for individual needs and to monitor for any adverse reactions while taking them.
