What products should be in the medicine cabinet?

In absolutely any first-aid kit there should be medicines for first aid - these are antiseptics (Aseptolin, Miramistin, alcohol, brilliant green), dressings, syringes, needles, a tourniquet.
Painkillers - pentalgin, analgin, antispasmodics - at least a banal no-spa, NSAIDs will also come in handy - this is the beloved by the people Nimesil, Nurofen.
It is very useful to have antihistamines on hand, especially in the form of injections, in case of anaphylactic shock, insect bite.
The god of any first-aid kit is also Panthenol, when it is needed, it is traditionally not at hand. Perfect for burns, with it you can use solcoseryl, for the healing of large wounds and abrasions - "Rescuer".
Vishnevsky's ointment is a proven means for pulling off pus, irreplaceable in everyday life and in surgery.
Vasoconstrictor nasal drops - for the timely restoration of normal breathing in various rhinitis and rhinitis. In addition to the classic "Otrivin" there is an even more expensive and hormonal preparation, but excellent in the case of allergic rhinitis - "Avamis". Also a good local antibiotic for the nose is "Polydexa", it will also help reduce swelling of the mucous membrane.
You can't go anywhere in the modern world without activated carbon. To him it would be logical to buy the banal "Loperamide" for constipation, as well as have at home "Maalox" - a remedy for heartburn and to reduce the acidity of the stomach.
Necessary nitroglycerin, captopril, the presence of antiarrhythmics, especially if there are people in the family with a tendency to heart disease.

It seems that having a first-aid kit is vital, but if you are not a doctor and live in a city, then you need it rather for convenience. And put in it only those funds that are needed most often.

- Painkillers and antipyretics. Aspirin (at temperatures it should not be taken until the age of 19), ibuprofen or paracetamol (syrup and suppositories are better for children).

- Anatacids. Needed to deal with heartburn or upper abdominal pain.

- Oral Rehydration Medication. The powder is dissolved in water and drunk with diarrhea and vomiting to prevent dehydration.

- Antidiarrheal agent (loperamide). It should not be given to children, and adults should be taken with caution: if there is no fever and blood in the stool.

- Antiseptic (chlorhexidine). It is needed if there is an infection in the wound.

- Moisturizing eye drops. With their help, you can rinse your eyes if something gets there.

- Antihistamines. First generation allergy drugs (Suprastin, Diphenhydramine) often cause drowsiness, second generation drugs (cetirizine, loratadine, fexofenadine) do not have them.

- Hydrocortisone ointment, cream or emulsion. It will help with itching and pain from insect bites.
