Fildena Chewable 100 mg contains Sildenafil 100 mg and is used for erectile dysfunction. Because counterfeit ED medicines are common, it is important to check the product before taking it. How to check if a Fildena Chewable 100 mg tablet may be fake: Buy only from a licensed pharmacy and avoid tablets from unknown websites, social media sellers, or loose/unlabelled packaging. Check the packaging carefully: Spelling mistakes, poor print quality, blurry logos, missing batch number, or missing expiry date can be warning signs. Look for a manufacturer name, batch/lot number, manufacturing date, and expiry date. The seal should be intact and not tampered with. Check the tablet appearance: Compare the colour, shape, markings, and packaging with a genuine product from a trusted source. Be cautious if tablets look different from previous supplies or have unusual smell, texture, or crumbling. Verify the batch: Use any manufacturer-provided verification system if available, or ask the pharmacy/manufacturer to confirm the batch number. Do not take it if: The tablet is loose without proper packaging. The label is unclear or the source is unreliable. The tablet causes unusual effects or severe side effects. A fake sildenafil tablet may contain too little, too much, or the wrong ingredient, which can be risky—especially for people with heart conditions or those taking nitrate medicines. If you share a photo of the front and back of the strip/box (including batch number and manufacturer details), I can help you check visible warning signs.
