Allergies and Intolerance

Ineffectiveness against Viral Infections

This medication is powerless against viral infections such as the flu or the common cold. It should not be employed for these conditions.


Allergic Reactions

Given the potential for serious and occasionally life-threatening allergic reactions during penicillin treatment, individuals with prior penicillin allergies, cephalosporin antibiotic allergies, or sensitivities to other substances should inform their healthcare providers before using Devapen 400 I.M.

Procaine Reactions

In some instances, especially when administered in large single doses, rapid and toxic reactions to procaine may transpire. These temporary reactions encompass anxiety, fear, fever, rapid heartbeat, increased blood pressure, vomiting, dilated pupils, and sensory hallucinations.

Pseudomembranous Colitis

Nearly all antibiotics, including Devapen, carry the risk of causing pseudomembranous colitis—a severe intestinal inflammation. If you experience diarrhea while using this medication or in the weeks following its use, prompt medical consultation is imperative.

Long-Term Usage

Prolonged use of Devapen may lead to infections unresponsive to its effects or fungal infections. Long-term usage should be diligently monitored by healthcare providers.

The truth is that when we’re sick, or worried about getting sick, the internet won’t help.

According to Wikipedia, cyberchondria is a mental disorder consisting in the desire to independently make a diagnosis based on the symptoms of diseases described on Internet sites.

Why you can't look for symptoms on the Internet

If diagnoses could be made simply from a textbook or an article on a website, we would all be doctors and treat ourselves. Nothing can replace the experience and knowledge of specially trained people. As in any field, in medicine there are unscrupulous specialists, differences of opinion, inaccurate diagnoses and incorrect test results.
