To avoid improper use of this medication, it is important to know what its main contraindications and side effects are.

What is blood pressure
Before answering the question of whether paracetamol raises blood pressure or not, it is important to know what blood pressure is. Blood pressure are the values that the force exerted by the blood flow itself on the walls of the arteries when it is pumped by the heart.
The tension is measured by means of a stethoscope accompanied by a bracelet that will exert pressure on one of the arms, which will show two main values: systolic pressure and diastolic pressure. Although there is no exact figure, values that are approximately 120/80 mmHg are generally considered normal. If the measurements obtained are not close to normal, the blood pressure is classified into 4 categories :
- Hypotension: blood pressure is below approximately 100/60 mmHg.
- Prehypertension: the values obtained are slightly above normal (either around 130 mmHg or between 85-89 mmHg).
- Type 1 hypertension: the values are above what is healthy (between 140-159 mmHg systolic and more than 90 mmHg diastolic).
- Type 2 hypertension: blood pressure is approximately 160/100 mmHg.
Does paracetamol raise blood pressure or not? – here the answer
For those wondering if acetaminophen raises blood pressure, according to the MedlinePlus medical encyclopedia, the answer is Yes, acetaminophen can raise blood pressure and thus can aggravate cases of hypertension. Paracetamol, being a medication within the group of analgesics, can cause fluid retention, which consequently causes kidney problems and an increase in blood pressure.
For this reason, although it is an analgesic that can be purchased without a prescription, it is important that you do not consume it without first consulting your GP.

- Other analgesics and anti-inflammatories: non-steroidal drugs, ibuprofen, indocin and piroxicam.

- Hormonal contraceptives: birth control pills, patches and vaginal rings among others.
- Antiflu: pseudoephedrine and phenylephrine.
- Immunosuppressants: cyclosporine and tacrolimus.
- Herbal supplements: arnica, bitter orange, ginseng, guarana, St. John's wort, licorice and ephedra.
