Sildenafil, a powerful medication commonly used to treat erectile dysfunction, is the active ingredient present in a number of leading ED medications. Two notable options are Cenforce 100 mg and Kamagra Oral Jelly. Available since the expiry of the Viagra patent, these two medications are changing the landscape when it comes to getting effective, affordable medication.

The difference between Cenforce 100 mg and Kamagra Oral Jelly lies within their formulation. Cenforce 100 mg is a traditional hard tablet, while Kamagra Oral Jelly is a gel. This differences in formulation impacts the absorption rate and onset time of sildenafil.

Sildenafil Activation Time

The activation time varies depending on the formulation. Kamagra Oral Jelly, being a gel, dissolves quickly in the mouth and is absorbed rapidly by the body, as quickly as 15 minutes after intake. Its quicker absorption leads to a faster onset of action, making it a suitable choice for those seeking immediate effects.

On the other hand, Cenforce 100 mg, being a hard tablet, needs to be swallowed and broken down in the digestive system, which takes up to one hour to be absorbed into the bloodstream. This time frame is due to the time taken for the body to metabolize the medicine and the drug to reach sufficient levels in the bloodstream.

Sildenafil Duration of Action

Despite the differences in activation time, both Cenforce 100 mg and Kamagra Oral Jelly, once activated, demonstrate a similar duration of action. The medicine typically peaks within the first 4 to 6 hours of activation. During this period, patients can experience the optimal effects of the medication.

Once in the bloodstream, it may remain active for up to 24 hours. However, it is important to note that the effects gradually decrease after the peak period as the drug is gradually metabolised and excreted by the body.

Side Effects of Sildenafil

Like all medications, sildenafil can cause side effects. While the majority of patients tolerate sildenafil well, there are several minor side effects to be aware of:

  • Headaches: This is the most common side effect. Hydration can help reduce this effect.
  • Flushing: Temporary reddening of the skin, particularly on the face.
  • Nasal congestion: Some people may experience a blocked or stuffy nose.
  • Dyspepsia: Also known as indigestion.
  • Dizziness: Usually mild, but can occasionally affect balance.
  • Visual disturbances: Such as blurred vision or increased sensitivity to light.
  • Back pain: Typically, mild and temporary.

Use Sildenafil Safely

Despite the success of sildenafil in treating erectile dysfunction, it is essential to use it responsibly. Always follow the dosage instructions, take advice, and never exceed the recommended dosage. Moreover, individuals with pre-existing conditions or those taking Nitrates should discuss their conditional with a health care professional. 

Understanding the side effects and duration of action for any medication is important to maximising the benefits.
