Medications that should not be taken before driving include: 1. Sedatives and sleeping pills: Phenobarbital-class drugs often have side effects such as drowsiness, fatigue, dizziness, and in large doses, can cause ataxia, temporary memory loss, and impaired consciousness, which can affect a driver's judgment and reaction time, leading to accidents. 2. Antihistamines: First-generation antihistamines, also known as sedating antihistamines, including diphenhydramine and promethazine, can induce varying degrees of dizziness, vertigo, fatigue, attention deficits, and slowed reactions. Overdosing can worsen these effects, making them unsuitable for drivers. 3. Antispasmodics: Atropine, scopolamine hydrobromide, and belladonna tablets may cause dizziness, blurred vision, and attention deficits. 4. Antipsychotics: Both typical and atypical antipsychotics have sedative effects and can cause dizziness, blurred vision, fatigue, drowsiness, attention deficits, and slowed reactions. Overdosing exacerbates these effects, making them unsuitable for drivers. 5. Cough suppressants: Drugs like pentoxyverine and dextromethorphan can cause dizziness, headaches, drowsiness, and fatigue, making them unsuitable for use while driving. 6. Analgesics: Morphine, codeine, and pethidine can cause dizziness, vertigo, fatigue, drowsiness, attention deficits, and pupil constriction, impairing driving ability. 7. Ulcer medications: Omeprazole can cause dizziness, tinnitus, blurred vision, drowsiness, and numbness in the legs; cimetidine, ranitidine, and famotidine can cause dizziness, fatigue, and drowsiness, all of which impair driving ability. 8. Anti-angina medications: Propranolol and mexiletine can cause headaches, blurred vision, tinnitus, and hypotension. High doses may lead to bradycardia, heart block, or even fainting, requiring caution while driving. 9. Anti-angina medications: Propranolol and mexiletine can cause headaches, blurred vision, tinnitus, and hypotension. High doses may lead to bradycardia, heart block, or even fainting, requiring caution while driving. 10. Blood pressure and diabetes medications: Unlike drugs affecting the nervous system, antihypertensives like propranolol, reserpine, and nifedipine can cause drowsiness, headaches, dizziness, and hypotension, affecting driving safety. All diabetes medications carry a risk of hypoglycemia, especially insulin and sulfonylureas. Taking them on an empty stomach increases risks. Improper use can lead to drug-induced hypoglycemia, causing palpitations, dizziness, sweating, and collapse, all hazardous for driving.

I remember one time I drove after taking cold medicine containing diphenhydramine, which made me dizzy and nearly caused me to sideswipe a guardrail. Since then, I've been extra careful: many medications should never be taken before driving, such as painkillers like codeine or fentanyl, which can cause severe drowsiness; antihistamines like chlorpheniramine have similar effects, slowing reaction times; even sleeping pills or antidepressants can impair judgment. If everyday cold medicine is labeled 'not suitable for driving after use,' it's best to stay off the road. The risks of driving under the influence of medication are too high—accidents are more likely, and you could face fines or license checks. I recommend checking the medication instructions and waiting until the effects have completely worn off before driving. Safety comes first, protecting both yourself and others. It's also a good idea to keep some non-drowsy alternatives on hand.

When it comes to driving under the influence of medication, from a health perspective, I must remind everyone that it is very dangerous. Common problematic medications include sedatives such as Valium or sleeping pills, which depress the central nervous system and slow down hand and foot reactions; antihistamines in cold medicines can make people drowsy; even blood pressure medications sometimes cause dizziness. The key is to pay attention to the warnings on drug labels and avoid driving during the peak effect period of the medication. I recommend consulting a professional before taking any medication and choosing non-drowsy alternatives; if medication is necessary, wait at least a few hours to allow the body to metabolize the drug components. Safe driving is not only about personal safety but also involves the well-being of others—don’t risk major consequences for minor gains. Developing the habit of reading medication instructions can help prevent accidents.

After having children, I became extra cautious about driving safety. Driving after taking medication is absolutely unacceptable, especially cold and cough medicines or sleep aids, such as those containing diphenhydramine, which can impair your focus. Every time I'm responsible for picking up or dropping off my kids, I make sure I haven't taken any such medications. If I feel unwell, I ask family members for help or take a taxi. Avoiding driving under the influence of medication is a basic responsibility to ensure the safety of the whole family. Simply checking the ingredients of the medication is enough—don't take unnecessary risks.
