So for clarity:
- Pseudoephedrine HCL is an effective medication, and can also be used to make Methamphetamines so is now more restricted although still over the counter. It is what is in the branded medicine Sudafed, but is basically a naturally occurring drug.
- Phenylephrine HCL is not an effective medication in tablet form, and the US FDA has decided recently to remove it from sale after studies showed it performs no better than placebo. This is what had been in the branded medicine Sudafed PE, and was a patented drug in 1927.
So one is an effective generic naturally discovered drug that cannot be patented, and the other is an ineffective drug that although off patent now has been pushed by the pharmaceutical industry for nearly 100 years. In fairness, nasal spray Phenylephrine is likely to be effective - it is the tablets that are ineffective.
The packaging is likely the same to deliberately confuse consumers, in the same way the original major brands are Sudafed and Sudafed PE. Once medications have to be bought from a pharmacist behind the counter rather than just taken off a shelf it sells less well, so better for the Pharamceutical industry to ensure people think they’re the same thing even though one is useless.
