Nicotine and Pseudoephedrine, a caution.
Pseudoephedrine and nicotine can both raise heart rate, blood pressure, and sympathetic tone. Pseudoephedrine has a measurable pressor and chronotropic effect in meta-analysis, while nicotine stimulates sympathetic neurotransmission and cardiovascular activation. The combination is most relevant for people with hypertension, palpitations, coronary disease, anxiety, or heavy nicotine use.

Caution
What is happening. Pseudoephedrine and nicotine can both raise heart rate, blood pressure, and sympathetic tone. Pseudoephedrine has a measurable pressor and chronotropic effect in meta-analysis, while nicotine stimulates sympathetic neurotransmission and cardiovascular activation. The combination is most relevant for people with hypertension, palpitations, coronary disease, anxiety, or heavy nicotine use.
Mechanism. Pseudoephedrine is an indirect sympathomimetic that promotes norepinephrine release and stimulates alpha and beta adrenergic activity. Nicotine activates nicotinic acetylcholine receptors in autonomic ganglia and the adrenal medulla, increasing catecholamine release and sympathetic cardiovascular effects.
Recommendation. Use pseudoephedrine cautiously if you use nicotine patches, vaping products, pouches, cigarettes, or other nicotine products. Check blood pressure and pulse during the first day of combined use, and avoid extra doses if you feel palpitations, chest tightness, tremor, or marked anxiety. Choose a non-stimulant decongestant strategy if you have uncontrolled blood pressure or heart disease.
