Any of the OTC medications that people take for headache and fever will help for someone that has hypertension, just be sure and read the label carefully. There are many brands of medications on the market that say you can safely take if you have high blood pressure, just be sure you choose one that is safe for someone to take that has high blood pressure. Also, check your blood pressure more often than usual while taking medication.
As with any medications, OTC or prescription you must be careful of interactions. With some BP meds., an interaction with anti-inflammatory drugs such as ibuprofen can interact and affect your kidneys. Always read your pamphlet that comes with your medication. Your trusted pharmacist will also explain the possible interactions if you have questions about your medications. I know this is way later than actual question date. Hopefully someone with same question will realize that NOT ALL OTC meds will be safe taking if on medication for hypertension.
My Dad had high blood pressure and was taking medication for it, he also had no problems taking regular paracetamol for his headaches. He also took later on in life osteo-panadol for his bad knee. So I would guess Panadol is ok.
